Hey I just finished my custom made adapter to accept the mazda oil sending unit, as most of u know that the 80 does not comes with a oil gauge and a sending unit. Anyway I made my 80 to accept the 82 gauge cluster that comes with oil gauge and custom made an adapter to accpet the sending unit.This is what I did drill the rear oil line bolt and tap it. I have thread good for the sending unit but I use a white teflon tape on it so it won't leak? Now for my ?,what other seal can I use beside the teflon tape? I have test it and rev the engine and I don't see any sign's of oil leaking but with the rotary heat u never know what can happen to the teflon tape? thanks, khris

 

Sounds like an interesting idea. I have an 80' engine as well and I'm going ot need to do something abut the oil guages. What you did is a good way to save $45.

 

i use liquid teflon and havent seen any problem.

 

Are you saying that you drilled and tapped the banjo bolt that attaches the oil cooler line? That shouldn't get too hot to cause a problem with teflon tape.

 

I saw one in the junk yard like that. He had a liquid sealant on there. White stuff, kinda like what you would put on pipe threads. Probably the same stuff.

also, what you can do is add a "T" on the banjo bolt fitting to accommodate for a stock oil pressure and after market gauges.

 

Or buy an oil distribution block from Steve at www.rotaryautosports.com . They look great and work great too .
