Oil Pump

I have one or more oil leaks I need to deal with, one looking like it's from behind the oil pump. At 385k, I might as well replace it since I'm in there. Think there's any difference between the Aisin pump on Rockauto for about $75 vs. the "Genuine" Toyota pump, which I believe is also Aisin, p/n 15100-62050 for about $210?

I would appreciate any thoughts on this subject as well.

 

First thing is pack the gears with grease and the seond thing is use a toyota gasket only... there are horror stories of people using aftermarket cover gaskets and having 0 oil pressure, apparently too thick of a cover gasket will not allow the suction side of the pump to pull oil through the pickup, the gears are sucking air and not oil.

 

Packing the pump gears with grease? Haven't heard of that. This is a 3.4 L. In terms of the gasket, think there is one paper version on the pickup tube, an o-ring that sits against the block, and then FIPG between block and pump.

 

An Aisin pump should be fine, it is probably identical to the OEM pump.

 

When I did mine on the 3rz, didn’t use grease but a basic petroleum jelly. Just smooshed it into the gears and oil pressure built right away

 

That P jelly recommended to me by member Thatt
No issues after installation

 

You're probably right. They scratch something out on the one from RockAuto - could be "Toyota", hard to make out. Be aware if you order this one it does not come with the pickup tube paper gasket or the o-ring for the block. Don't be like me, and make sure you have those before you plan on doing the job.
