Oil pressure is too high.
I got my bird back on the road after being down way to long.
The motor was swapped. One of the mods I did to the M54DS pump was change the check ball from .625 to the .5625 and shim the spring. I also used one the 1/4" spacer plates on the pump. I think I used the VR1 racing oil. I believe its 20W-50 weight. Not completely sure. The pressure is at 80psi most all the time. Around 60 at idle. I wouldn't think the mods or the thicker oil, would cause the pressure to be that high. I was going to change the oil to a much lighter weight and see what that does. This is a roller cam and lifters, so I wouldn't think I would have to be concerned with zinc additive. I was considering like a 5W-30 Mobile 1. Thoughts? |
