View Full Version : EGR and blowby

My question seems to be overlooked in the other thread so I thought I'd post it here:

Is blowby normal if removing EGR on a EGR equipped vehicle? The Mustang TEMs I got had the EGR hole welded shut so I just deleted the EGR on the car and now I notice some blowby in the dipstick tube. This can't be normal? Nothing else has changed.

No, deleted EGR does not cause blowby... Improperly setup PCV, on the other hand, can cause issues to crop up.
