Message I have a 1995 TTZ, 5speed with 155K miles on the clock, with stock turbos, JWT Stage 3 Ecu, Stillen turbo back exhuast, and pop charger..

Recently bought it a week or so ago with the passenger side turbo seal apparently leaking oil bad... now the drivers side turbo seal went out while doing routine short distance moves between the work area for it, and the body shop for paint and body estimates...

It was running on 5W-30, but once the leak started, switched to 20w 40 to help her smoke less in the mean time.

at idle, the stock oil pressure gauge is reading 80-95 PSI and 120 PSI at hwy speeds of around 60 75 PSI..

I am fairly mechanically inclined, and from the research I have done on here that is to HIGH.. I will be doing a "TRUE" test of the "ACTUAL" pressure in the morning by tapping into where the sensor is next to the stock sensor with a known good gauge..

Until I get to that leg of the investigation, "IF" I am reading this "HIGHER" than normal reading with my external gauge.. what "MECHANICAL" issues could be the cause??

IE: Valves, etc... AM I looking at a complete rebuild..??

Thanks for the input ya'll..

~M.
