how would i install an mechanical oil pressure guage on my JDM H22a without having to drill into the block??

thanks guys

 

Tee off the oil pressure sending unit. I'm not sure of the thread sizes though.

Yup

The engine block thread is 1/8 BSPT (British Standard Pipe Threading) and the oil pressure gauge will most likely be 1/8 NPT (National Pipe Threading....I think).

So you'll need an adapter going from BSPT male to NPT female, an NPT tee (make sure you put it on the firewall, not directly on the block), and an adapter from NPT male to BSPT female (this will be for the oil pressure sending unit that was initially in the block).

There was a company online that had everything you would need.....I forget the name. Mc...something, some help me out if you know.

thanks guys. i just went off of the back of the block. and NO LEAKS!!! gauge works great... but i saw the pic of what you explained. i'm most likely end up doing that with the braided line, when i get some spare time to do it.

anyways thanks' for your help

That's a really good idea, because 4-cyl engines produce a lot of vibrations and there is a possibility that whatever you have hooked up to the block might break off wiith the vibrations. That's why it is suggested to hook the tee to the firewall.
