After my car warms up for about 30 seconds it begins to produce a thick blue smoke...I thinkit is because oil is somehow geting into the exhaust because once it warms up it smoke for about a mibute and then doesnt smok at any other time. Any ideas on why this i s happening? I have a straight back exhaust with a borla tip...no emissions on it

 

Make sure it's oil, and not fuel. The car will run rich while warming up, and might smoke a fit if choking too much.

Now, it could be oil leaking into the chambers while sitting for a while, but I doubt it. If it is oil, then the only real fix would be to replace the seals (rebuild time). Short term fix; use Lucas heavy duty oil stabilizer in place of 1 or 2 quarts of oil the next time you do an oil change.

 

Are you carburated or FI?

 

did you have good results with this? Mine smokes like crazy whenever I start it, and i just want a temporary fix until my engine is rebuilt.

 

Lucas rocks man! I use it in all of my engines since I first tried it in my 7 to help the oil control rings (used to smoke horribley on deceleration).

 

I'm carbuerated...I'll definately give that lucas product a try because im pretty sure its not fuel causing the smoke. how long does it take to replace the seals and how hard is it?

 

Check and make sure your OMP is not stuck partially open. Check your linkage to make certain there are no binds.

 

How many miles on the motor? High mileage motors have that issue at start-up. if it goes away once warm, drive it until it blows.

 

the motor was rebuilt so it has about maybe 2,000 tops because of my license suspension....

 

I was wondering, do the early RX7s have to run for quite a while before smogging the car effectively, one of you said that it runs rich when it first starts. Could that be my problem. And does anyone know where I can find the interior sterio panel for my '82?

 

Yes, it is best to drive the car for a bit, prior to getting it smog tested. The cats do not work as effectively until they reach optimal temp.
