Oil pressure gauge install issue

jmroy6 · 04-16-2021, 10:25 AM

I have a different adapter that threads to the engine block so i just drilled and tapped a NPT thread for the sensor.

It looks like you cant do that. Would you be able to use something like this?

Not sure why I didn’t think of tee’ing the sensor there! looks like this should be a pretty easy/compact solution. Too bad I just put in fresh oil and I don’t have an extractor... guess I’ll be waiting another 3000 miles to install

Any chance you remember if your relocation block has 2 o'rings like shown here? The smaller o'ring in mine was mangled so I had to find one that sorta fit. I'd like to replace with the actual o'ring but I can't find any info about the GTM kit. I don't think theres any manufacturer markings on my block either. I also don't see any other kits online that use this second o'ring, so I'm wondering why this one has it and if its necessary?

If anyone knows anything about the GTM kit please let me know!

You need that o-ring. Otherwise you will get unfiltered oil leaking into filtered oil.

Makes sense. Any idea why it looks like most sandwich plates (like this Mocal unit) don't have this o'ring?

It's the way it's designed.
