Recently had a oil pan denting issue on my 172k gtp. I have fixed the pan and replaced the pickup tube. Wasn't too bad but you could see where the pickup tube was marking the bottom of the oil pan.
I thought i fixed it because when it could started i didn't have a knock. I test drove it. When the engine temp went up it started to have a knock to it. I don't drive it anymore. I have stated it a few times since to move it. It always sounds great when its cold. Doesn't start to knock until like 190 degrees.
I was thinking maybe replace the rod bearings with the engine in car. Maybe the oil pump isn't doing well? The knock sounds pretty healthy when you hear it. Wouldn't it knock all the time if something was bad wrong? Instead of only when it warms up. Just looking for some idea's to get her back on the road one day.
