Looking for help

[jmallen05]

I started my engine today after re-gasketing it this winter and now I think its worse then before. The oil pump cover leaks like crazy. When I replaced the gasket I found a stripped stud and now I think its leaking by other studs as well. What I would like to do is pull the cover back off and drill them all out to the same size like 8mm just to be safe. Also when I started it the oil pressure light was on. Could it be on because of the leaky oil pump cover. Its leaking really bad. Is there anyone in the gr area or willing to drive too gr to give me a hand. I have little experience and few tools. I think I'm going to have to pull the engine again and could use as much help as I can get. I would need some advice and tools to tap the block for the oil pump cover and help with diagnosing my oil pressure problem. Please let me know.

Can you add 2 washers and a new nut on each side ?

[jmallen05]

I don't know, I don't understand what your trying to explain. The threads are stripped out of the block and 7mm studs and bolts are impossible to come by. Has anyone used rtv grease on the plate or does the paper gasket normally work.

Jerry, use NOTHING on the oil pump cover, besides the gasket of course. The last thing you want to do is suck a piece of RTV into the pump and push it through the system. It can also change the tolerance between the cover and gears, losing pressure. I'm guessing you currently have stripped 6mm threads? I would continue on the 8mm route.

I figured that much, thought I would ask anyway. The cover leaks enough to carry a steady stream. Do you think that is why its not reading any oil pressure? I didn't have any oil pressure issues before I pulled the engine, I was hoping that would be the problem.

Is the idiot light on the left generator and the right oil pressure? The colors are faded so I can't go by that.

Jerry,

You shouldn't have fired the motor without taking care of the stud problem first. If you can't find the 7mm to go in you need to take all of them out and tap to 8mm then you will need to drill the cover slightly to fit the 8mm studs. The steady leak is most likely your oil pressure issue. Don't worry we will get it fixed up.

I thought the bolt I had in it would work until I found a stud but I guess not. Looks like I'll pull the engine again and buy a tap set. When we pulled the cover it had wear marks on it from the pump rubbing against it. Is this normal, or could that be part of my problem?

After reading on thesamba it looks like this isn't uncommon. The 6mm stud tends to strip from the block on a 1500 because its made from a softer metal. They were suggesting to tap them to 8mm, thats what vw started doing. Does anyone know if I can do this without pulling the engine? Or is the apron too close to get a drill in there?

My bad , I thought it was a stud . Heli - Coils are easy to install . Or J-B Weld if its oil free .

[Dustin]

We should have taken the cover and inspected it more. The wear marks should be sanded down if not too deep or the cover replaced. Then inspect the gears of the pump and check their clearances and check the pump shaft to make sure its tight and does not wiggle.

This is what I recommend and that would be drill then tap the 8mm thread. Then use the oil pump plate with the larger holes or just drill the holes larger.

I have taps with the correct drill bits if you need them and I have a oil pump plate with the larger holes if you need that. Also I have studs too

The stud centerlines are not the same on the 6mm and 8mm oil pumps. Keep this in mind when you decide to either repair the thread or enlarge the size.
