It seems like my car is getting major blow back in the motor after doing a pull. We went and tuned the car yesterday and noticed that after a good pull and the car pulling deep vaccum it will puff a cloud of whiteish smoke. I instantly thought the valve seals were shot but the motor is FRESH and has under 1k miles on it (GSR w/ BC IV cams, Crower vt, and PR3 Pistons). The car pulls great and isn't using any oil at all (that i've noticed). Nor is it using any water.

I'm not venting the Valve cover and the black box is still on teh back but not hooked up to anything. Should I vent the VC to a catch can? Do you think that would help with the smoking? Its driving me up the damn wall! Makes me not even want to hammer

This is my first B-Series as I've always been a D-Series turbo guy. A few B-Series buddies said that most B's will smoke like that... Any input?

 

you should always have your block ventilated. Reconnect the black box breather on the back of the block the way it's supposed to be and see what happens then.

 

hook up a catch can system or syock pcv system. check your tune under vacuume. if you can datalog. record datalog and stop it 3 seconds after the smoke, just makes it easier to dial in when the smoke happens throughout the table

 

I'm going to hook up the stock black box this coming weekend.

I'll hook up with my tuner and do a datalog and see what it shows. Good thing my tuner is one of my best friends. Or i'd be broke as ****... LOL
