mystery hose (2)

[sactoC10]

Picture number two, from the driver's side. What is that brass fitting for the looks like a vacuum fitting, and why did I get oil leaking there before tightening that hose.

[ozarkhippie]

What dope smoking old man plumbed pressurized oil into a valve cover where a pcv valve should go.

[71-longbed]

hey sacto

i notice you have the same idle solenoid as me ... i wish i knew more about those buggers... .. i have no idea what that fitting is doing there.. i dont have one

[Class of 69]

In 37 years of working on vehicles, that is the damndest thing I've ever seen!!!I am at a complete loss as to why someone would want to put oil into the intake manifold??!!It appears to be adapted to one of the intake mounting bolt holes. I would remove the valve cover, and see if someone drilled thru the head casting to provide oil in the head. If the hole is still a blind hole, remove the whole goofy setup, and plug the hole in the front of the block with a pipe plug and put a bolt back in the intake. It is not factory, nor should you need it, unless there is some other modification in the head. That hose is bleeding off oil pressure to the front cam bearing, and timing chain and may be doing a significant amount of harm.

Well I guess I'm the dope smokin old man I was looking at the splice and fitting in the pcv hose lol

[cranknut67]

That's like majorly funky. - if I was you I would stick the appropriately sized plugs into those holes.
that might give you a bit more pressure and less made fun of..

j/k about that last part..

[rickh]

Could it be a smoke set up?
Not sure why someone would want to do that, but if it had a solnoid on it hooked to a switch and it its plumbed into an intake runner.... lots of smoke!
Dumb idea, but like everyone else, I have never seen anything like that before!

I kept looking and looking and looking and I did not see ANY engines with this line anywhere. No wonder no one knew what I was talking about!!!

"blind hole" Class of 69, what does that mean? I ought to check and see if the hole goes deep? Is that it? And as for plugging the hole in pic #1, just get some thread lock and a short bolt? What is a pipe plug? Both of them are threaded in, so I'd think a bolt could go in there easily.

Please keep advising...as you keep laughing.

Maybe it is a good thing that there is a donor vehicle I am looking at buying!

[dinnut]

thats possible..

A blind hole means that the threaded hole bottoms out. In other words, the hole doesn't go all the way through, but only part of the way into the material.

Forget the bolt and pick up a proper plug for the bottom end of that contraption. They're threaded like a bolt, but (usually) have a square head instead of a hex and they're normally pretty short. You'll definately need one for the bottom connection and, if that top one's not blind, you'll need one there, too (or suffer a HUGE vacuum leak).

Beware that a plain bolt is likely to leak. Why? Because they're not tapered and the shoulder of a "normal" bolt isn't mean to make a pressure seal which is what's needed here. Any parts store should have tons of 'em in stock and nobody will snicker at you if you use a proper plug.

Any way you choose to go, I'm with everyone else here. First, I don't have the slightest idea why anyone in their right mind would do this intentionally. I figure this is a 18 beer f*%k up. In other words, it'd take me about three 6-packs to do something that dumb.

Second, listen to Class of 69. Yank the top end of that thing and check to see if it's a blind hole (doesn't go all the way through... in other words, it bottoms out). If it is, RUN to your parts store and get the plug you'll need to get rid of that thing.

If it's not a blind hole, yank the valve cover and look for a head modification. I really doubt you'll find one, but you never know. If so and you're not terribly familiar with the business end of an engine, you should probably leave well enough alone and have someone you trust take a peek.

If that line goes where one of the middle intake manifold bolts is supposed to be then that hole I believe goes through the head towhere a push rod runs.

[shuttermutt]

Holy smokes!

I just took a second look at that picture. That sucker's plumbed into an intake manifold bolt hole, isn't it?! At first glance, I thought it was just a manifold hole. Dude, that is seriously weird.

If you do end up pulling that thing (man, let's hope so), be aware that you'll need a pipe plug at the bottom end and a real, proper intake manifold bolt at the top.

Geez... I'm gonna have freakin' nightmares about that rig tonight!

[dinnut]

i just too noticed that it is plumbed into the intake mani bolt hole. thats weird

[RussTburb]

How is this for a theroy?

Jr. is trying to change his intake with out pappy's help. he accidently brakes a manifold bolt in the head. (seen it lots). Jr. grabs daddys black and decker and starts a drillin'. Well the next thing ya know ol Jeds a million air seams he struck oil! now what! well lets put a hose nipple on it and run all that oil back into the injun were it belongs right? Just a thought!

[sactoC10]

What to do first? OK, get to the parts store and get the holes plugged with the correct fittings...and that's OK and good to do, right?

And get fittings, not bolts. Ya know...each of those has a fitting into another fitting, so simply find what will plug the fitting.

But why am I worried about the depth of the hole that goes through the intake mainfold? I can't do anything about it can I? Do I really need to get the intake manifold off ASAP?

Wife needs me (better things to do right now), I'll check these again in the morning.

Thanks, keep it coming. (btw, 18 beer-LMAO!!!)

[Class of 69]

Trouble with that theory, RussTburb, is that the oil pressure is coming from the block at the front of the line and going to the intake.
DO NOT pull the intake!!! Remove the valve cover, the metal cover on the head, and look for anything unusual in there. Better still take a pic of it, and post it, and we'll tell you if you have anything weird in there. I doubt it too, but seeing that hose makes me wonder just WTF the PO was doing??!!
Your wife has something BETTER than talking to US !!!
The only reason I'm still here is, I've already been told it's too late for that Why is it "too late" for a woman, but never for a man??

[Longhorn Man]

Why is it "too late" for a woman, but never for a man??

Why is it women always need a reason...all I need is a place.
They should try thinking like us...they'll enjoy life better.

[sactoC10]

Here it is again, in all of its messed up glory!

[sactoC10]

is pictured here...

[Class of 69]

I meant, take a pic of the head with the valve cover off.
I thought you went to be with the wife?
Oh,...you're done already!! Welcome back LOL!

[gonebad2]

If a bolt did break off in there, try drilling it out. If the threads in the head are damaged, use a helicoil. BTW...The bolt you need is 3/8" coarse thread x 1-1/4". I have seen people use a longer bolt and it hits the pushrod...Good luck..Keep us posted.

[Hooter]

what is the other side hooked up to?

[BtnkBndt]

Looks like an adapter fitting to an elbow. Maybe they threaded the manifold hole?

I would just remove the thing and try seeing if a standard manifold bolt will still thread into the head. If so, coat it GOOD with sealant and torqe it down. (If it won't thread looks like you will have to remove the intake and tap an heli-coil the head). Then just plug the one on the block. If it runs and doesn't leak after this, go with it.

Hooter,

From the pics it seems to go from the manifold bolt to the front of the block??? I looked at this post last night and thought I was just seeing things. Apparently I'm not the only one seeing it.

Thats what I want to know.....if we knew that maybe we could figure out what the PO was thinking....or smoking...lol

Wherever this is.Is that the front of the intake, or the timing cover???
