Smog
I sold my 87 K5 to a kid I know, he smogged it last week and was told it almost passed but would have to be taken to a Gold Star smog station after he fixed a few issues like the plugs & wires, change oil, basic tune up stuff. Today he was told by the gold star station that it passed emissions but he couldn't give him a cert because it blew a puff of white smoke when he hit the gas. The guy tells him he might need the heads done, new EGR, and maybe a new cat converter. The kid and I have already put a lot into this thing, he can't afford new heads right now and I'm already out way too much on it as well, I gave it to him for $1500 and put half that much back into it to help the kid out. Anyone have any experience with these Gold Star smog stations? Any ideas how to get it to pass without spending more money? By the way the kid and I agreed he would take care of the smog. Thanks for any suggestions, this is a good, hard working kid, kinda rare these days, I really want to help him out.

Re: Smog
As much as I hate to do it, I hate CA smog more, what about some no smoke in the oil just to get it to pass? I'd rather see a safety inspection for the junkers I run into on the highway then smog.

Re: Smog
I'm not sure if it does, only heard of people using it. was it white smoke, blue smoke? that's probably a good question to ask first, was the truck hot when you tested it? I used to always get my oil changed, fill up with premium, run it down the freeway and when i got to the smog place I would leave it idol until they were ready. it's such a pain and especially when your trying to do something nice for this kid. Maybe try a different shop? never heard of this Gold star, are they a test only station or a test and repair? and does it puff every time you hit the gas?

Re: Smog
From CA DMV
Gold Shield Program Fact Sheet Scheduled to end in 2013 and will be replaced by STAR Test Only and STAR Test and Repair stations. STAR Performance Standards (Starts 2013) November 2010 The Gold Shield Program is designed to make the Smog Check Program more convenient for consumers. It allows a licensed Smog Check station, that meets higher performance standards to provide a variety of inspection and repair services to California consumers. In addition to the regular Smog Check inspection and repair services, Gold Shield stations can inspect and certify "Directed Vehicles," issue certificates to "Gross Polluters," and perform state subsidized repairs through the Consumer Assistance Program.

Re: Smog
The smog guy now seems to think some valve seals will most likely take care of it, I've never done it but it seems pretty straight forward. If its nothing more than pulling the valve covers, rockers and holding the valves up, we could take care of it easily (an assumption) what surprises would I find putting seals on it? Special tools other than a spring compressor? Thanks!

Re: Smog
You'll need a plug hole fitting to hook up an air line to hold up the valves. Other than that it's a straight forward job. You could try using some 20/50 oil to cut the slight valve leaking down enough to pass if it's that close. I have used a product called engine restore in the past and it has cut down oil use albeit temporarily. Good on you for being a helpfull seller I'm sure the kid apreciates it.

Re: Smog
Truthfully, Id try a different station, not all smog techs are all that strict on the visible smoke test. Unless the laws have changed you dont have to get it repaired at a Gold Shield station, it can be done at a test and repair station also. Really the deal with the Gold Shield stations is that theyre allowed to repair as well as certify a car that is a test-only car while a non-Gold shield test and repair can do the repairs but they cant certify it, after repairs it will have to be certified at a test-only station.

Re: Smog
What weight oil is in it? I'd put a straight weight oil in it, at least 40 or more. Add a bottle of hyperlube or Lucas stop leak. Use a different test only station. That with a fresh tune up will probably pass. With the new visual "is it smoking" rule, your truck is on the very slippery slope and a rebuild, at least a valve job, is in it's future. Also all smog test results are automatically, electronically sent to the DMV, they can see all tests and the results.

Re: Smog
If it's "white"... it's prolly water vapor. If it's "bluish white"... it's oil. Which is prolly what it is. Which would be normal for a vehicle that old with probably a lot of miles. Valve seals could do it for ya, to get you by this year. But you might be lookin' at new valve guides or a re-ring in the future.

Re: Smog
Just pull all the rocker arms off and plugs out and use your compressor fitting in the cyl your going to do. Do one cyl at a time (do not remove springs before chamber is full of air).you only need about 70 psi to hold the valves up but more is ok if they are a bit leaky.the engine shouldn't turn at least I have never seen one do it. Another old trick is to stuff some nylon rope in there to hold valves up but I dont like that one due to it could get stuck or leave shreds behind. Good luck

Re: Smog
We changed the valve seals today, went well until I tried out the piece of crap spring compressor I just bought! One of the hooks was just a little too long (or the other too short of course) and it kept slipping off. Don't buy cheap spring compresors! Anyway I got it too work after a little practice. The old seals were split, dried up or completely gone. The rockers and top of the head and inside valve covers were spotless clean,I was surprised how clean it was. the valve stems seemed very tight, I had compressed air holding them up but I couldnt feel any play in the valve guides. I put it back together and started it up getting a single puff of smoke then nothing, just "clean" exhaust. We let it sit for a couple hours and started it again and still no smoke. Hopefully that will help it pass smog this time. He is going to try out some Restore and change the oil with some 50 wt, it's been hot here so I don't think it will hurt anything. Thanks for the advice everyone! I will let you know what happens when he takes it back to the smog guy.

Re: Smog
Smog tests suck! We changed the valve seals, EGR valve, changed the oil, all the things the smog guy told us to do, things he said would cure the issues. This morning the kid took it back and it failed again, this is the fourth time, the first test locally and three "gold star" tests, now the smog guy says a new cat converter will fix it! This sucks, each trip to the gold star smog shop cost over $100 with gas and the cost of the test. We've spent at least $200 on parts and now have to spend another $100 for a new catalytic converter and another $100 for gas and another test. It's going to end up costing $1000 by the time it's all over and we don't even know if a new catalytic converter will fix the problem! I'm thinking he should sell the damn thing or part it out at this point!
Do I have to buy a specific converter or can I get one out of a similar sized, low mile wrecked truck at the junk yard? I have found a few universal converters for around $50, will one of these work or should we just go for the specific model made for the truck? Any suggestions or recomendations would be GREATLY appreciated! Maybe I should compress the exhaust out of my wife's car, it had zero emmisions it's last test, put it in a bottle and pipe it to the K5s exhaust, heck I could make some fake pipes and pump the bottled exhaust into it! I am so glad my trucks never need smog! Another reason to drive old trucks! Thanks all! Again, any suggestions, no matter how ridiculous will be considered at this point! Posted via Mobile Device

Re: Smog
No, the truck doesn't smoke at all since we changed the valve seals, not a single puff of smoke! I'm not sure the specific reason for the failure this time, I'm waiting for the kid to get back with the printout, it's a four hour round trip to the smog shop.

Re: Smog
The smog tests 4 different exhaust gases at 2 speeds. Which test/speed failed and by how much? A "new" cat will generally clean up all but has the most dramatic effect on HC and NOX usually by about 1/2.

Re: Smog
ok, don't laugh... But an old guy told me when I was a teenager with a chugging old 57 bel air with dual quads and header glass packs to pour a can of heet (fuel line anti-freeze) and put 3-4 mothballs in the tank about 25-50 miles before the smog check. I have no idea if it made any difference, but it passed every time and always pissed off the smog check operator. Smog check machines are probably a bit more complicated nowadays, but this was the Indiana tailpipe sniffer test, if that helps.
Now, I'm not sure I'd go throwin any moth balls in my tank today, but there you have it. Heet cannot hurt the engine. Just to give you an idea of this old guy's crazy remedies, believe it or not - a half jar of corn meal sealed my (bad) radiator leak. Also used pepper in another radiator with a pinhole leak and that worked too. No, I'm not kidding. Bottom line - I may have missed above if you've taken it to the same guy repeatedly - but if you've been twice and failed, I'd never go back to the same dude. |
