Ok so my oil pump is leaking so I was going to change the seal. Is there a gasket or something behind the oil pump I can only find the round seal on O'Reilly's

 

There is no gasket - you use the black goop sealer stuff but there is a small o-ring that should be replaced if you are removing the oil pump.

 

Ok thanks

By "black goop sealer stuff" hidesert may be referring to FIPG ("Form in Place Gasket"). That's an excellent Toyota product that sets very quickly. Great if you're charging by the hour, need to get the vehicle out of the bay, and are practiced enough to get the pump correctly in place first time, every time. That's not me; I like a little more "open time" to get the part installed correctly, and I can wait to the following morning to start it up. So I like Permatex Ultra Black https://www.permatex.com/products/ga...asket-maker-4/

Your choice.

 

Ok thanks and if someone could answer this question also that would be great. It's leaking from around the bolts would I need to replace the middle o-ring seal or would it be fine just to reseal the oil pump

 

Do it right! If you go to the trouble of removing it clean it well, use the correct sealer and replace both the o-ring and the crankshaft seal.

 

Ok thanks
