1990 Jeep Cherokee Problem
So I am new to this forum, as you can tell by my posts. After all that aside, here is my problem.
I own a 1990 Jeep Cherokee. I've owned it for 1 1/2 years. It had given me some trouble, but we finally solved the problems. A couple weeks ago, my dad and I decided that we were going to replace the Oil Pump because my pressure was dropping.
So he ordered the part, we replaced it one day, put everything back together, and started the engine. A major oil leak occurred. We replaced the oil pan gasket with a rubber one, instead of the standard cork. It still leaked. So we took it in to a local garage where we get all out vehicles worked on. It ended up being the main seal for the engine, and after a $631 repair, it did not leak. So we were happy for a couple weeks. The oil pressure was staying up, we didn't have trouble starting, and the engine ran great. Well last Thursday, I started my engine to go to work, and I noticed the valves were tapping. I didn't think anything of it, because its always done that. The next day I get in, and the valves were louder. I was curious because it never did that before.
After a couple days of the valves getting louder, and no way to quiet them. It started tapping extremely loud. I would start it up, and it would rattle so loudly that you could hear it from inside the house. The valves would tap all the time. And when you accelerated, revved the engine, or just idol it would tap. But when the engine got over 2100 RPM's, it would be tapping loudly. I have no idea what is wrong with it. I read through my jeep book, and no answers on it.
Any help would be nice. I know I do not have much info on it, but its late, and I am tired. Thanks for everything.
