Oil pressure and whine!

[PropXprt]

I rebuilt my engine about a month ago. I used a crapline front cover on it, it just recently starting sounding like my oil pump is whining real bad. It whines all the time and gets louder as rev's go up. I also have half the oil pressure that I used to. I've got everything off of the front end... I am contemplating pulling the front cover off and replacing it with another (new pos crapline) that I have sitting here. Any ideas what may have caused this or what else might be making this noise? I'm about fed up with this car!!! All I want to do is drive the damn thing.

Um....maybe you should replace the oil pump then and not the front cover. I believe they changed the design of the pump so the grooves are angled instead of up-down. If you really think it's the oil pump, hook up a drill to the pump (14mm) and spin it for like 5 seconds. Don't do it for too long because it'll build up pressure pretty damn quick and you might cause things to leak/break/split apart/etc.

Well the reason I said replace the entire front cover is because I have a complete new one sitting here. Although I will take your advice and hook a drill up to it and see if it is the oil pump. I sure hope this is all it is... I sure hope it isn't something like a main bearing.

Thanks for the reply.

Have you noticed any new vibrations at all?

Thanks for the replies you all. The oil pump was the problem, just turning it by hand it was obvious. Luckily, I accidently bought two of them when I was doing my rebuild. So I will throw this one on and see what happens.

I love my car! !

Update: If anyone cares. My stub shaft came unbolted from the gear in my oil pump. What kind of luck is that! I pulled my oil pan and found the stub shaft laying there.
