To be clear the mating surfaces are fine but theres a small ridge on each side where the oil pan mates to the block. What should I do about this? I have a Felpro pan gasket and I thought maybe it would seal this. I was also going to dab some rtv on there but I'm not too sure about it.

 

Does anyone have experience with this? Do you think it'll be okay?

 

was your block lined honed in the past? check the clearance around the crank and front oil o ring to see if its centered properly.

 

any pics? the one pic u have is showing a red box

the only work I've had done cylinder bore and decking.
Clearances were checked beforehand, everything was good. If you can see that image, the other side is not as bad as that one.

 

a dab of rtv there and u should be fine..... only way to truely fix it is to pull the studs and use a flaper sanding disc and make it flush. but its not a big deal as the gasket is slicone or rubber and will seal that little bit of difference...

 

Alright, I hope so. That Ultra Black does hold like superglue when fully cured. Thanks for the help.

 

Another thing. I cannot get this stupid crankshaft sprocket(for the timing belt) back on. It came right off now problem whatsoever when I first removed it.

 

Are you absolutely sure it's the correct oil pump?

The problem I'm having with the sprocket doesn't have anything to do with the oil pump. The sprocket goes onto the crankshaft.

 

that sprocket will fit on a z6 and /or y seriies motor... it should fityt as long as the key groove lines up

 

That's what I'm not understanding. The sprocket came off this very crankshaft with very little effort now I can't even tap it on.

 

Clean corrosion off with a wire brush. I've had to tap them on with a rubber mallet before even

 

I've cleaned it off. I've even sanded material off the sprocket and its still too tight. If I try to bang it on there the end of the crank starts digging into the sprocket

 

I guess I was too scared to damage the crankshaft. A few good, hard wallops and it drove down on there.
