Low oil pressure
So I've been reading several post re: low oil pressure , and having that problem myself, I joined your forum. I have a Buick lasabre with a 3800 with 150,000k
When it'* idling, the oil light comes on, so like many before me, I put mechanical gauge on , and the pressure is 5-7 lbs hot idle. When reved it picks up to 25-35 lbs. I have bought oil pump repair kit from melling,but after reading these forums, it looks like these pumps don't go bad, I did however replace the regulator & spring. No change, so I've pulled a couple of rod caps and see wear, not enuff to make noise however, the engine has never made any bearing or low pressure knock or rattle.
So here'* the $64000 question? Did the low oil pressure cause the bearing wear? Or did the worn bearings cause the low oil pressure?
If I replace the rod bearings, will I get oil pressure back?
