Re: Which Oil Pump Spring
OK, guess I was thinking correctly by going to the black 60# spring. I was thinking it would be ok to leave the 70# spring and just alternate oil viscosities, but I am used to running the 15-40 oil.
One thing that has caught my eye is the mating surface on the rear main cap to new oil pump. When I pop it on to the dowels with out being tightened down, there is a little "rocking" and that is leading me to think the mating surface on the main cap to oil pump surface , is not perfect.
Now this surface is parallel to the sealing surface of the rear oil pan gasket seal. My thinking is that IF there is a leak at the cap to oil pump surface, it could be shooting a hi pressure ( 70#) stream directly on this deal, thus causing forced pressure on the sealing parting line of the pan and gasket. Possible? So, I remove my main cap, stud, and dowel pins, I will lap this cap to oil pump surface on a piece of glass with fine sandpaper to reveal and uneveness and hopefully make the surface true.
Tim, No I did not add rtv on those pan end seals ,only the corners as I always do, but it getting a new gasket, another new blue main seal and RTV. Good luck for me as winter storm hit this morning after blowing sand for 3 days and I will not be missing any cruising.
I am really not concerned now about oil temp as since I got this motor together and added the rear intake bypass water lines to T-stat adapter, my water temp is lower by 10-15°, so I am good here.
Thanks All for the input, black spring it is.
