Re: Glock's new project: "Fred"
 

It's just mocked up for the photo op. I still have to put the fan on. :D

Probably would, but then again, this is only temporary. I plan on making a 4" tube that runs over to the drivers side, then turning slightly towards the radiator support. I just happen to have this old intake setup in one of my sheds, so it got used just to get me going and to put the $$$ in other places.

I don't think an inch would matter too much. This setup just happens to almost perfectly centered the fan in the shroud. But this too is only temporary. The 06 truck electric fans are waaay too wide for the stock 85 radiator, so this is just to get me running and on the road. Later I'll build a custom shroud with a couple e-fans in it.

So in a few months the clutch fan, shroud and stock intake tube will all be bye-bye.

Re: Glock's new project: "Fred"
 

Bob,
I could make one of these fittings for you out of 303 Stainless. I doubt it would strip as easy as the aluminum fitting. Also, I would almost bet if that part you purchased is made from 6061 Aluminum. It's readily available and it's pretty strong.

Seriously, send me a drawing with the male end thread specs and I can program that part and send it to you. Not a problem we have fall off that would probably work for you.
Mike

Re: Glock's new project: "Fred"
 

Mike, that's awesome!! I'll get something drawn and send it to you.

Re: Glock's new project: "Fred"
 

Mike - PM me an email address, and I'll email you a .DXF drawing. It's not to scale, but it should give you what you need.

Re: Glock's new project: "Fred"
 

Hmmm, how's this? The female (top) is 3/8NPT, and the male threads are M12x1.5 and about 1/2" or so long. It is of course drilled straight through too.

It's about 1.75" tall (not including the 1/2" of male threads), and I think I used a 7/8" wrench to tighten it.

Re: Glock's new project: "Fred"
 

What a cool pic. Looks sweet from the top..:metal:

Re: Glock's new project: "Fred"
 

Thanks Travis! Even got the spider webs in the pic! :lol:

Re: Glock's new project: "Fred"
 

Man, that thing couldn't look more at home in that engine bay. Great work.

Re: Glock's new project: "Fred"
 

Is that what that is. :lol:

Re: Glock's new project: "Fred"
 

This will work for the geometry. What about the pilot hole that runs through the metric side? Did it have an O-ring groove too?

Re: Glock's new project: "Fred"
 

Actually, yes kind of. It has a brass washer instead of an o-ring but there is something of a groove between teh last thread and the base of the adapter.

Well.........

I got one of the tanks installed tonight, and did a pressure test of all the fittings. 55psi with key on and no leaks! :metal:

That's the good part. The bad part is I tried to fire it, and nada. :( I've got power to the fuel pump, power at all 3 ignition points on the fuse block, and power at the 1 battery hot point on the fuse block. I didn't really get into it beyond that, or else I may have been there all night until I found the problem! :lol: I don't have the passenger side O2 sensor yet, so nothing is plugged in there, but I don't think that would keep it from starting.

So I'll finish installing the other tank tomorrow after work and then leave it until Saturday. Maybe I will be able to come up with some ideas by then. I'll probably take up residence on top the engine with a wiring diagram and a DVOM and start checking all the sensors.

Now the real fun begins!!!!

Re: Glock's new project: "Fred"
 

I thought about this last night laying in bed. I need to check for spark of course, and that I'm getting the proper power and ground signals from the PCM to the injectors. But I feel fairly confident that the injectors are plugged. It's not uncommon at all for the injectors to plug if the engine has not been ran in a month or so, and this one has sat in my shop for a month now, and who knows how long it sat at Rancho. Plus I'm sure California puts about a million different additives in their fuel, so that's just more reason to think they are just plugged.

So if all the electrical tests check out, I'll probably pull the injectors and send them out to be ultrasonic cleaned, rebuilt and flow tested.

Re: Glock's new project: "Fred"
 

Bob, Right on with no leaks!! I think your on the right path w/ the trouble shooting... of all the start-up threads i have read its 1) bad ground on the electrical 2) fuel pressure not between 58-61psi? and 3) there were a few with the clogged injectors and if i remember right they just lightly tapped on each injector while firing??..

Re: Glock's new project: "Fred"
 

Makes me wish now that I hadn't turned them 180° so they wouldn't be visible! :haha:

Re: Glock's new project: "Fred"
 

:lol: i know what ya mean... if it will make you feel any better i'll put mine in turned around like yours before the 1st fire up;)

Re: Glock's new project: "Fred"
 

After a phone call to my old drag racing buddy Dave Slatten, I found out this guy in literally right down the street from me: http://www.totalinjection.us/ :metal:

And I mean literally, right down the street! I can see the shop from my parking lot here at work!! I will probably be talking to him today!

That would make me feel a little better! :lol:

Re: Glock's new project: "Fred"
 

Dont forget a couple have been vats not being disabled...

Re: Glock's new project: "Fred"
 

True, but my experience with VATS is that it will start, but die shortly after.

Short of checking spark and power/ground to the injectors, I am leaning towards stuck injectors.

Re: Glock's new project: "Fred"
 

Bob, I love the overhead shot. Glad to hear the preasure test went well. Now, ge the rest figured out. Way to go man! :metal:

By the way, I don't remember seeing anything about a driveshaft? Did the original one still fit or did you have one built, or did I just miss that all together?

Re: Glock's new project: "Fred"
 

I was a machinist in the Air Force for 13 years and worked at the flight test center repairing and building test aircraft parts & equipment and have made & redesigned many things like that over the years. There are a couple minor things you may want to fix if you are going to make a new one.

Where the small metric male threads transition to the hex stock put a 1/4" fillet radius there. It will increase the strength of the part tremendously.

It doesn't need to be that long either. Less length will put less load on the threads if you accidentally lean against it while working on the truck. It would suck to snap that thing off flush with the head. The closer you can get the sensor to the head the better.

If you can make it out of brass or aluminum bronze that would be much better too.

The stainless will need antisieze compound on it to keep from galling the threads and getting stuck in the head plus the galvanic corrosion from the dissimilar metals will cause the aluminum head to oxidize around the fitting possibly causing it to leak down the road.

Aluminum bronze or brass will only need Teflon tape as they are much closer to aluminum in the dissimilar metals range chart.

You could make it out of round stock and just put a set of wrenching flats on it to use more common scrap material.

If you did strip out the threads on the head you can always tap the head for the 3/8" pipe threads of the sensor and be done with the adapter. Just put some grease on the tap drill and on the tap and they will collect the shavings so they don't go into the water passage.

Re: Glock's new project: "Fred"
 

When I put a 93 LT1 & 4L60E into my 67 Chevelle the VATS was not disabled in the programming at first. It would fire while in the start position but die as soon as the key was transitioned back to the run position.

You could spray a little fuel in the throttle body and it would fire up and run for a second.

After getting the chip programmer to do it right the thing fired right up.

My motor had been sitting for close to two years with no injector clogging issues.

VATS may not be disabled in your PCM.

Re: Glock's new project: "Fred"
 

Making good progress man. It's looking amazing. Getting all giddy waiting for it to fire up.

The old VATS would do that, but I think the newer ones just crank, and never turn over. I wouldn't think this is it though. The guys that did your pcm and such are pretty good, and VATS is usually a big priority to be disabled so I'm sure they did it.

Re: Glock's new project: "Fred"
 

Anybody know how VATS works on the newer trucks? My only experience with it is the older versions with the resistor chip in the ignition key.

There is nothing like that on the key to my 03 Tahoe. Maybe it is buried inside the key out of sight.

The older system I was able to physically bypass by jumping a pair of wires under the dash. I yanked the computer and 305 TBI motor out of my 91 RS and dropped in a brutal 408 small block that no longer used any computer controls. It wouldn't start even though it still had the correct resistor chip in the ignition. Turns out there is a mechanics bypass harness out there so I was able to use that info and figured out what needed jumpered to get it to start with no ECM in place.

Maybe there are a pair of wires you can connect or a single wire you can supply power to that will tell the PCM that the VATS module is sensing the correct information to allow the engine to start.

Re: Glock's new project: "Fred"
 

The new ones are lot more advanced than the early 90's ones. The chips are in the plastic head of the key. Not all of them have them though. Most chip keys, and non chip keys look identical, with exception for a few. At my hardware store we have a little chip reader box we put the key in and reads if it has a chip. I don't think you can bypass the newer systems like you could the earlier ones either. I know the older ones you could just put a resistor in the wire like you stated, but the newer ones you have to pretty much have it disabled in the PCM.

Re: Glock's new project: "Fred"
 

All late model trucks use serial VATS, which is simply deleted in programming. Serial VATS is designed to run and fire the injectors for 2 seconds, then shut everything down if a series of data is not generated in the BCM (body control module) by the key, steering column, etc. The is nothing to bypass with serial VATS, it's programming is simply deleted in the PCM programming.

I remember doing alarm and remote start systems and having to match up resistors with the same resistance as the vehicle to get around it when installing remote starts.

Re: Glock's new project: "Fred"
 

Just sold the e-fans that I got with the engine for $125. Also just got the refund from Autobarn.com on some 3/8" FI hose I ordered that I wound up not needing, another $46. I will also be sending back the 3 AN fittings to Summit when I get them, another $44 back in the budget.

Re: Glock's new project: "Fred"
 

Nice! Recycle old or unused new parts to buy new parts, it keeps the wheels moving :metal:

Re: Glock's new project: "Fred"
 

I should be working on Fred right now, but it's kinda nice relaxing with my kiddos too. Fred will still be in the shop in the morning.

Re: Glock's new project: "Fred"
 

:metal: good idea buddy. take a night off and enjoy what you have around you. i'm a firm believer that i take too much for granted in everyday life and one never knows what they have until its gone! so kick back and enjoy it.

Re: Glock's new project: "Fred"
 

Good for you man! The kids like to be out there with you...but I am sure they like having you in with them too. I hope all goes well on it tomorrow. I will try to keep an eye on here from work. ;)

Re: Glock's new project: "Fred"
 

All I can say is Wow! You do some amazing work!

Re: Glock's new project: "Fred"
 

Well, Fred starts and runs!!!!! ;metal: But the electric throttle isn't working. Diagnosing that right now.

The problem was the ignition wire I was using to trigger the relays. 12v disappeared when the key was turned to "start". Figured that out while testing power to the coils. Changed that and it fired right up.

Re: Glock's new project: "Fred"
 

:metal::bann::hot::four::two::ele::wave::ennyd::five::cong:





now where's the video?

Re: Glock's new project: "Fred"
 

I think the TAC module is bad. I don't have a 5v reference signal at one pin that should, and a low reference signal on another is missing. I'm going to see if any yards around here have one in just a bit. Rancho has been really slow in responding to me lately, and I don't really want to wait a week or longer for them since I really want to drive this on our cruise next weekend.

Also, I seem to have a miss on the right side, might be a plug.

Anyhow, here is a vid for now:

Re: Glock's new project: "Fred"
 

I knew that is who would be behind the wheel. Little show off. :lol: I felt some room being made in my zipper area when it fired up. :D Nice job Bob!

Re: Glock's new project: "Fred"
 

man that is SWEET!!!!

I can't wait for some burn out videos :burnout:

Re: Glock's new project: "Fred"
 

Congrats!!! nice very nice... can't wait to start on mine....

Re: Glock's new project: "Fred"
 

Yep, all the stuff he said!

Re: Glock's new project: "Fred"
 

Well, I still can't get the throttle to work. I am missing a 5v signal on one pin of the TAC module, so I still think the module is shot. There should be 2 reference signals; one the increases voltage and one that decreases in voltage when the pedal is pushed. As of now, both signals go up. So until I get a scanner, I'm kind of peeing in the wind.

And it runs a little rougher at an idle now too. So there really isn't much more I can do to it at this point without a scanner. I have the ODB II connector coming, but I will have to wait until I get some more $$$ to get the scanner bought. There is one guy on another forum that wants my LS1 intake, but I still haven't seen the $$$ yet.

I'm thinking unless some drastic changes happen in the next few days, I'm probably not going to make the cruise this coming weekend. :( I do know there is a yard in Loveland that has the TAC module I need (only 2006-07 used this part #), I might go get it because I don't want to wait on Rancho. If I have it, and if that's the problem, then I might still be able to make our cruise.

Otherwise, I found NO fuel leaks, no trans cooler leaks, and no power steering leaks! And the temp sending unit adapter seems to be sealing too. :metal:

It's just the kids and I tonight, so I think we are going to go clean up and head to Sonic for some http://www.co-diva.org/forums/style_...ult/hungry.gif http://http://www.co-diva.org/forums...t/eatdrink.gif then maybe come home and http://www.co-diva.org/forums/style_...ht_lifting.gif to take my mind off of it for a while. :D

Re: Glock's new project: "Fred"
 

right on!! sounded good Bob! man, i hope you can get it figured. this is where i run out of ideas... except 1 which you have already covered. find a scanner... good luck! i'm gonna watch it again. :lol:

the kiddo's were happy as can be. thats awesome;)
