Occasional Rich Fuel
 

Now I've got one more problem to worry about after cleaning out the PCV system. Now the car has occasional bursts of smoke out the tail, which smell of unburned fuel. Seems to only do it at idle and when making left hand turns. What could be causing this??

Any codes in the system?
The light might be off but still have codes stored.

Yes, I think that was the problem. Apparently when the turbo hose fell off it stored 2 codes in the computer, one for turbo boost regulation, the other for idle valve/intake leak. There was no check engine light on. So I cleared the code, started it up, and didn't see any more smoke, but didn't drive it either. Hopefully this fixed the issue. By the way, the procedure in the Haynes manual for checking the codes is wrong.

I don't doubt that one bit

It actually worked to my advantage though when I bought the car, I kept trying to check the codes according to the manual, and it says the #6 hole is the diagnostic hole, so anyway it wouldn't return any codes at all, and I told the seller that I was concerned that maybe the computer was bad. I didn't know any different, and that combined with everything else she thought was wrong with it gave me a lot of leverage when it came to price. I tell people how much I paid for it, and they are actually accusing me of ripping the lady off! I mean the car has 220k miles, wouldn't read the codes, and it smoked like a chimney. I suspected it was the PCV, but who can really tell with that many miles? I don't know what you guys think about it, but I don't feel one bit guilty about it, especially considering that she was ready to call the salvage company to come get it!

I think you ripped her off. It's only fair that you go back and offer her more money. Better yet just deposit the money in my paypal acount and I'll square things up with the lady for you.

I hope the stored coeds solve your problem. I make it a point to check the computer for codes each time I change the oil. Its funny how some stored coeds will turn on the check engine light, while others will not.

I think it wasn't rich fuel after all, I noticed it starting to put smoke out the dipstick again, so I got to looking and realized the piece that fits into the turbo pipe had partially fallen out. I may need to order a new one, because the rubber is so deteriorated from the heat and oil that it was nearly impossible to get it to stay in.
