Oil Pump O-ring Mod - Testers NEEDED

***TitaniumTT*** · 11-10-2009, 08:00 PM

I used the 13B-RE metal gasket (similar to the Renni but no need to trim) along with the white teflon piece and the o-ring. Everything pressed in all nicey nice. I have no idea why it popped out. Now that I think more nad more about it though, the there is no other o-ring to pop out of place. I hate that setup, I really do. I'm thinking about plugging that passage on the iron and reeming the iron to the side and using an NPT to -10 AN fitting on the next engine I build. Just seems like an uneccessary potential failure.

Rot Inspired - my idle is MUCH lower than yours and such it would be expected that my oil pressure lower @ idle. I'll check the logs when my laptop is up and running again to see what the OP is @ 12-1300. When my engine cold idles at that speed I see about 90-100psi

I like the idea of doing this kind of oil pressure mod but doesn't excessively high oil pressure like that cause problems? I would think you would want flow and that pressure that high is not necessarily a good thing.

13B-RX3 did a good write up on what you're describing on the other site. Though it's a better setup it would be over kill in a street car IMO. Though the front cover o-ring does fail from time to time it's been around long enough and worked well enough that I don't really consider it an issue.

What I have looked for an would like to try is a copper or aluminum crush washer instead of the o-ring but I have yet to find something that is the right combination of diameter and thickness. When I mentioned earlier about the o-ring squeezing out without a gasket on the front cover, that is from experience. We found the o-ring in the cooler many miles down the road. Thing is idle oil pressure on this engine was still solid at around 40 psi. The teflon retainer had been squeezed enough (since I didn't use a front cover gasket) that it was doing the job of holding the seal. Again, I would like to try something similar with a soft metal crush washer.
