Recently built an m50 stroker, s50 crank, nonvanos 135mm rods, m54b30 pistons with new rings gapped over for turbo, new crank bearings, new rod bearing, Athena cutring headgasket, I use an m52 oil pump, use a vanos oil filter housing (used the vanos feed to feed the turbo), rebuilt hx40 with 3/4” oil return and 4AN oil feed w no restricter. The oil return is at the correct angle, and it is above the oil pan. All parts were cleaned and inspected prior to assembly.
My issue right now is my oil pressure. When the engine is at cold idle the gauge would read 40-45psi. When the engine warms up and reaching operating temp, the gauge is reading 60-65psi. Isn’t it suppose to be the other way around? I am using 20w-50, is this oil not appropriate for this application?
Yesterday, I decided to take the car around my block. I didn’t push the engine, no hard acceleration. When I got back into my garage, smoke was coming my turbine; there was oil coming out on the bottom of where the bearing housing and the turbine meets. Seal blown from too much oil pressure? Has anyone experienced this? Obstruction in my oil passages somewhere? I am getting oil pressure but it is just high at operating room temp and low at cold.
thanks.
