Alot of smoke came out of the exhaust after the test...I let the car idle and then took it for a spin. After about 15 minutes of driving did the smoke stop. Did I do something wrong?? Also the pressure test seemed like air was leaking through the oil cap is this bad?

Most likely you gave the crank case a good dose possitive pressure air, forcing oil past the rings and into the cyl's or past the valve guides. The air coming from the oil cap is a tip.

I don't think you did any damage (short of oily plugs) and the drive burned out what little oil you forced into the combustion chamber. Check your oil level though!

Next time ease up on the pressure.

Also, what do you mean about the air coming through the oil cap is a tip??

OCA::DIY Motorsports

that is a tip that the crank case has positive pressure (among others). You just want enough pressure to test the intake system...yes?

Not blocking off the "Positive Crankcase Vent." valve would allow pressurized air into the crank case and the oil past the rings could result.

gotcha thanks...did you ever find out what was wrong with your car (with the CEL)

OCA::DIY Motorsports

the problem never surfaced again. No other CELs. I took it easy for a bit, but then last night I pushed it a bit and nothing...solid. I drove it today and again, a few 3 gear 5K runs and it seems fine. Bad gas maybe??

Today I pulled all the top covers to poke around a bit (general familiarization) and to see if I could see a cracked TBB, but nothing...all looks good. The car only has 11,600 on it so I did'nt think I'd find anything obviously wrong.

replaced it and it was better until 2 weeks later. It turned out to be a bad coil pack.

and point them in the direction of the coil packs.

Thanks.

You didn't cap off the PCV damper port.
