SMOKE SMOKE SMOKE
 

When i bought the car 2 years ago the exhaust fumes were clean, now my car smokes a hell of a lot when i start it/any acceleration. it has a 305 tbi with 166,000 miles on it, and flowmaster exhaust with the cayt removed. but the smoke just started about 6 months ago, does anyone have any ideas on how to fix/what is causing this, thanx

I had the same problem, it's your valve stem seals. They're worn and need to be replaced. It's a very common problem. When your car cranks it smokes and when you're at a red light and you hit the gas the smoke comes out and eventually burns out, but if it smokes all the time then it's your rings. Have you changed oil lately?

Yes, sounds like valve stem seals.

Head job anyone...haha

What color is the smoke? Blue is oil, black is fuel, and white is coolant. Makes a difference as to what the issue may be.

:yup:


Also is it when the car starts up after sitting for awhile or does it smoke all the time?

hey, thanks for the replys, it is blue oil smoke, and it smokes a little even when idling, but its when i start it/accelerate that i get pretty nice cloud

then its most likely the piston rings

I know what you are going through I have had enough 305's in my life. It could be valve guides, rings, camshaft, and various other things. What you have to do Is a good 'ol fashioned compression test. That will tell you exactly what is going on. You can pick up at Compression Tester up from any auto parts store, tool supplier, etc. for like $25.00 - $60.00 (depends on brand name).
