Hey what’s up guys. I recently bought a 95 VTEC del sol. With 228k miles on it. Drove it 4hrs back to my house, no smoke. I hit VTEC on the way a couple of times, no smoke. Passed emissions fine.

I just got a new full 2.5 stainless steel piping installed on the car, no cat, cut right at the axle back.

Got into vtec a few more times maybe 4-5.. with the new exhaust and the car now blows blue smoke everywhere, on decel, any acceleration past 5500 rpms, even on a 4K rpm decel.

I know its probably the rings. But the motor was gone thru before I bought it, apparently. The mechanic said everything looked good and showed no wear, and basically buttoned it up with new gaskets and called it good. The dude had the paper work too.

Could it be because of the new exhaust? The car was only driven 200 miles after the work and was sitting for 8 months I believe.

 

Time for a compression and leakdown test but with that mileage it's likely the rings like you are thinking...

 

So it’s nothing for a motor with that mileage, no smoke, no symptoms and the next day it’s blowing by like crazy

On the dipstick it isn’t burning anything either, it stays on full. But it’s deifently a oil burning blue smoke.

 

You removed the catalytic converter which will burn the oil vapors and turn it into carbon instead. Compression check.

 

Oh he removed the cat.

A quick test would be to pop a cat back in and see if it still does that.

 

My other car had a test pipe and it never ever smoked. I don’t have a compression tester, and I wouldn’t even do that because I’d just swap the motor for the one in my other car, if the rings are that bad.

I just wanted to know if it could be from the cat less exhaust install, or say maybe a bad pcv valve. I drove around today and it still smokes but not as bad

 

Compression test you rent from your local hardware store.

you can pull your exhaust headers off and see if oil is leaking from the valves and shooting in your exhaust.
Uou can also pull your spark plugs out to see if oil is leaking from the o-ring gaskets.

 

A new exhaust smokes until “broken in”

 

That’s what it seems like. Way less smoke

 

Guess not, smoke is still there. It’s after a pull or two and on engine braking. It’ll smoke all the way from 7500-2000 rpm deceling. I had the exhaust on for over a week, and been driving it around to try to burn off anything in the exhaust. But it seems like it’s just smoking

suggestions?

 

Do what was already suggested.
