So I finally got the timing belt and front seals replacement underway today, and when I opened the package for the crank seal (non-Subaru) I found a paper gasket was also included. It just happened to be the exact size for my oil pump. The oil pump that I removed from the car did not have a gasket, just some sealant. All the manuals and forum discussions I have read have called for sealing the pump to the block with OEM sealant or Ultra-Gray #599 (and thus I purchased the latter). I have not seen any mention of a paper gasket anywhere. What's the deal with this paper gasket? Something that they used to use? Fel-Pro's suggestion for sealing the pump to the block?

I also found that three of the screws inside the pump were loose and partially backed out. I have seen mention of inspecting these, but is it very common that they are actually loose? I put some loc-tite on them and tightened them down.

Way back when, about 45 years ago, I took some auto mechanics courses in high school. At that time, paper gaskets were quite common for sealing oil pumps. Remember that this is long before silicone sealants were readily available.

I'd use the silicone sealant, and ignore the paper gasket. Be sure to use only a very small amount of sealant. You don't want the excess to get into the pump's works. Be sure to clean both mating surfaces thoroughly before applying the sealant.

I'd be careful with non-subaru oil seals. I've heard of problems (leaks) if you don't don't stick with OEM for this part.

Glad to hear that you guys are in agreement. I used teh Ultra-Gray to reseal the pump but figured I would ask as this paper gasket was news to me.

my OEM seal turned to hard black crap in 60,000 miles, I put in a new OEM which had a different appearing rubber, but I wouldn't be afraid of an aftermarket one under the circumstances.

I wouldn't say it's not uncommon for the screws on the oil pump backing plate to be loose. I've heard quite a few people talk about it. Mine however were not loose.....and were pretty tight. So....not sure why that was the case....
