oil pump spacer
oil pump spacer Is it a good or bad idea to use rtv on the oil pump spacers when using a double roller chain? I put rtv on mine but now im paranoid some may have squeezed into the oil passage.
Going to take it back apart in a few days. Need peace of mind that it's not clogged. Freakin stupid mistake. Oh we'll better to catch it now than when it's in the truck.

I don't like metal to metal seals on a high pressure system. A lot of people get away with it, but I think you're losing volume and pressure. What's the point of using the best pump you can find, and then losing some of it's performance through a leaky seal?
I'd use a very light smear of silicone sealant. Does it really need it? IDK, but it helps me sleep at night.

The aluminum spacers are soft enough to compress like a gasket. You are sandwiching them between two machined flat surfaces. There is no gasket stock.
Why some of you guys think your smarter than the well paid engineer that designed them is beyond me.

Probably the same reason GM doesn't hand port their oil pumps.
Anyways i took it apart tonight and my concerns were correct. Some of the rtv had squeezed into the galley. So glad i took it back apart and checked it thanks guys. I put it back on and put a VERY THIN coat of threadlock on the spacer.
Good you got off the silicone but bad you went and used threadlocker.
It's not made for that-it won't do anything for you.
You've got it all apart so get with the copper spray and do it again.

Sorry guys but you are way over doing it. My stock motor (no sealant on oil pump) ran 40 psi oil hot idle. I now have a Mellings pump (HV) and bearing clearances far looser than stock and carry 55 psi hot idle with spacers for the double roller chain. Car makes over 1000 RWHP (twin turbo) now and has ran for over a year. 30+ dyno pulls. What ever little drop or 2 of oil per minute is lost is not an issue. But do what makes you sleep at night.
Mine makes 750 with no turbo. Rpm puts a strain on the oiling system the power is not as big of a deal. I have 90 passes and 4000 miles and 10 pulls on two different engines 7500 rpm with no issues.
I have spent quite a bit of time working with Schumann on their pumps. They found leaks at the block and a few other things that were killing engines in the Texas mile that are allowing the engines to live.
The inlet side of the pump is also a area that can benefit from a couple mode.
There is some new bypass recovery system that looks like it will show gains.
