i got the motor rebuilt about 10 months ago and then 3 days after drove it 3000 miles across country. runs great..no problems.

I didnt hook any gauges that where mechanical because i didnt want any leaks on the trip. so yesterdays i hooked up the mechanical oil pressure gauge to a sandwich plate on the oil filter

started the car up ran at 60 psi or so let it warm up and dropped to about 20 psi. SWEET!!

took it for a drive (cold) and it spiked to 100psi a few times. once warmed up it was all good. my question is... you think there was some air in the lines for it to spike to 100psi?? it never been that high before the rebuild??

2001 h22a4 Turbo
pistons/rods ect

stock oil pump!!

 

???

 

anyone?

 

Post this in the Forced Induction forum.

 

why???

 

If you can't figure out why yourself..

 

its mot a turbo question..its more of a prelude question personally.

 

There's nothing H22 specific about the question. There are only a handful of people in this forum who could reliably answer it. A lot of them don't post regularly.

This is a general engine (and potential turbo related) related question, the FI forum is dedicated to engine tech, a plethora of resource there.

 

anyone else?

 

mine at WOT is around 80-85 approx. im running an s2k filter with removed balance shafts on a stock pump. This is on an NA build with a basically stock h22a bottom end.

 

Sounds fine to my. My datalogged oil pressures max out around 90-ish PSI hot, and idle is under 20 PSI hot.

 

what weight oil are you using?

 

umm..this last oil change i think was 5-30.

so i guess im doing well then. i just never seen hit 100psi before when cold so it made me think a little
