Hi All,
Tried digging through PCV related posts but couldn't find an answer to this specific question.
I have a VTT headport block off kit with full external catch cans.
I recently installed a VTT oil cap breather and relocated inlets
Due to the relocated inlets I had to vent the high side to atmosphere as the VTT kit didn't not have a line that would run to the new inlets.
Anyway, ever since these mods I have been mixing oil and fuel something crazy.
Also the high side vent puffs crankcase vapors pretty heavy at idle.
I do not feel any vacuum at the oil cap. Normally should feel that light pull but not sure if that changed after headport block off.
There is actually a bit of positive pressure.
Don't have a manometer to test the exact value.
Replaced all my injectors.
Removed them and double checked they aren't leaking.
Removed my tune.
I've done 4 oil changes in 100 miles due to a strong fuel smell.
Compression is good.
Haven't done a leak down, tool is in the mail.
I know the recirc could of just been masking something bigger but the car has never mixed fuel and oil.
Doesn't really smoke while driving either.
Even after the initial installation of the head port block off and external cans.
I was running the block off kit and full external for a year with no issues.
Has anyone had this issue?
Is my pcv routing correct?
Would the oil cap breather cause this?
I've checked both check valves.
The one inline with the throttle body T ad well as the oil cap breather.
Everything seems to be working fine.
Any input is appreciated.
Thanks
Jay
