Hi guys.
Haven't posted for a while now but need some help please...
I've just finished rebuilding the gearbox and turbo and installed the MSD wasted spark kit 3 weeks ago and gave it some beans this weekend but noticed some blue smoke coming out the rear and noticed that the oil pressure was coming down when on boost.
All these readings were done with the engine hot and oil at about 100ºC and I'm using 100% synthetic 10w60 oil (it's 40ºC here in Portugal):
I'm getting 45psi on boost (at 4000rpm for example) and when I let go the throttle (still geared) the oil pressure goes up to 55psi. If i give it throttle again it goes down to 45psi.
I had to put oil in the car this weekend (the dip stick was at the lowest) and I haven't done more than 350 miles since it was full.
I have a racetech capillarity gauge.
Could this be a faulty turbo (it's new)? Main bearings? oil pump? all of them?
Can someone help me on this one? I'm getting a bit desperate now... I've had the car for 17 years now but it's becoming more and more frustrating. There is always something terribly wrong with it... I'm about to give up on him...
Thanks, André
