Re: Engine bearing noise?
If it was a bearing, I would take a close look at your oil psi. To adjust the lifters, purchased a set of the metal lifter clips and adjust them while the car is warmed up and running. I think the chilton manual tells you how to do this, if your don't know how to do it, LMK, it's easy. I suspect it's an exhaust leak. They tick tick tick

go to the local harbor freight, purchase a stethoscope and listen around the suspected area.
Just some thoughts to keep some easy diagnostic things to look at first before dumping a ton of money into an engine that may or may not need it
Keep us all informed as a conclusion to these typs of threads helps us all:tup:
