i have a rebuilt engine and now it reads maybe 1bar at idle then shoots up to 4 or 5 as rpms increase. but at idle 1 or less. just seeing if this is normal. was gonna hook up an oil pressure gauge at sender tomorrow. im running 20/50 oil now. thanks

Is this when completely warmed up? Make sure the crank bolt is torqued properly.

Is your oil pressure relief valve seated correctly? Long shot, but it could be binding.

A healthy reading is 3 to 3.5 at idle when warm. I went through this and it was a faulty oil pump.

i just hooked up an oil pressure gauge at port. 90 lbs at cold and 25 lbs warm at idle. seems to jump to 70-80 when i bring it up to 3k rpms. im assuming crank bolt and oil pressure relief are correct. these items scared me so had a porsche mechanic assemble motor. though my exhaust fell off while driving and a couple boots blew off under boost. thanks for input. ive switched to lbs instead of bar becuase not really sure how it converts and my gauge reads lbs.
