1987 740 turbo with lots of mods.
Decided to try do a cold boost leak test and ended up getting frustrated with air leaking past the turbo seals (apparently they need oil to seal up). Forgot I still had the end cap in and tried to start the car. The car struggled to start up and I thought nothing of it (stupid stupid me) but it did end up starting and running before i realized what I had done and turned the car back off.
Now Since the car started with an end cap in, that means that a lot of air could get in from somewhere else... And I doubt its from that tiny nipple going to the pcv...
Car still has about 18mmHg vacuum warm at idle but I can't help but wonder where all that air was getting in. I have pressure tested from the turbo outlet to the throttle body and it checks out fine holding 20 psi. Haven't checked post throttle body yet, but I was hoping you guys could give me some insight on where I may have caused damage.
