well to update this sawp/turbo install i've got good and bad news.
the motor runs which is good.
And the bad, my turbo was leaking oil bad from the compression housing and into the exhaust so I thought it was pooched and had it rebuilt........ STILL leaking oil, after adjusting a few things this is where im at with it. I am running a -4an (1/4") line with a restrictor for my feed off of a T on the block where the oil pressure sensor port is. For my return i'm running a -8an (1/2") line into a 45* bung into the pan (just north of the oil filter) ABOVE the oil line when the pan was full at 4.5 quarts...... I am so stumped I don't even know where to start?? It's like it's getting too much oil pressure, and not returning fast enough.... But both my feed and return are very similar to stock turbo lines. Any ideas?? I've tried to disconnect the PCV valves to eleviate any excess crank pressure,cranked over and still leaked.... I've pulled spark plugs to check for any fowling due to excessive blow by and couldn't notice anything irregular.
How ever apon firing (and note my idle isn't set and I don't have a tach set up yet) my oil pressure was reading around 60 PSI. Does this seem high? could this be my culprit? It seems high to me. i've read in the past as a foot note you should be at about 10PSI per 1000RPM.
If my oil pressure is too high.... what could be causing that??
