I have a 2011 Camry. 2.5L, 4 cyl, gas, not hybrid. The pump feels gritty when rotated by hand, and it makes a whirring noise that varies in pitch with the engine RPM.
I bought a pump locally from Carquest, and it came with a paper gasket. The dealership was open today, so I went in for some oil, coolant, etc. Turns out their pump gaskets were pretty cheap too, so I bought that. The tech said not to use sealant because it's metal instead of paper. Ok, understandable.
But will it leak if I use the metal OEM gasket with the Carquest pump? The pump was only half as much as OEM, so did they choose a paper gasket to make up for the tolerance differences by filling in gaps? Or is it just cheaper to make? The flat side of the pumpin contact with the engine looks like it's milled. I can see the grooves.
