I made a exhaust video yesterday for a member on here. I watched the video I made. After the car was running for a few minutes, maybe 5. I reved up the car a few times. The exhaust would puff a bit of white smoke with a blue tint. Is this normal for a car with headers and a catless ory? It doesn't smoke on start up. Any info or help would be great!

It's burning oil.. maybe the Valve Seals are shot..or the PCV System is sucking alot of it in.

Well that sucks. I'd bet either one won't be cheap to fix.

Check the PCV valve to see if it's soaked in oil. A catch can will help keep the oil out of the intake. Hope it's the PCV system as that's a common problem for modded cars and is cheaper to resolve.

If that is your problem run some MCCC after you install the catch can.

How many miles do you have on your car?

52,000. I went out to the garage with the wife. Started the car, no smoke. Let it run for awhile. The only smoke there was, was a white condensation smoke. I think it's from the cold. It's only 48* out. My daily driver does the same thing.
Anyways, I had the wife rev the car, no smoke, just the white condensation. It evaporated as soon as it left the tail pipe. I didn't see any blue smoke. The vid must have made it look blue. I have a cheap pos 4mp camera.

Who makes a good catch can? I found a few with a fast search. Just need to know what ones work the best. Thanks!
