checking main bearings on a 3.9
I been battling low oil pressure for a while now. I ordered a new oil pump gear housing, and while it gets here, I was told to check the gap on the main bearings...sometimes you can loose pressure that way? I have the oil pan out. But im not sure which gap im meassuring. Should I remove one of the bearings? Also, I feel a little play on the timing chain. Not much, but I can move back and forth a little. Is this normal? Rover has 145, 000 miles. Head gasket was done. But no work on the bottom half to my knowledge.
