Hello,

I am going Pre-Mix. I have searched around the site but cant find the size pipe plugs needed to block off the holes for the OMP. I hate starting a new thread but the searches turned up nothing with the exact size plugs. Pineapple Racing sells them but it does not say the size on their site and I dont feel like putting in an order for two small pipe plugs.

 

Meant Pipe Plug!!!!!

 

I'm about to do the same so am interested in what you mean. Do you not just make a metal block off plate and bolt it down using the holes you removed the OMP from?

 

OMP/MOP: N/A, 10mm x 1.0 bolts
TII, 10mm x 1.25

Oil Pan: M6 x 1.00

Oil Injectors: N/A, M10 x 1.0
TII, M10 x 1.25

Oil Injector Lines: NA: 10mm x 1.25
TII (some) : 10mm x 1.00

Oil Cooler: Front Cover is M16 x 1.5 — Rear of engine and both oil cooler are M18 x 1.5

Oil Feed Line Hole: front cover, 16mm x 1.5 thread pitch,
other three, 18mm x 1.5

Oil pressure sensor: 1/8” BSPT – 28 BSP

Rising RPM: Oil Injector Plugs <- (Out of stock.) :-/

I'm assuming they would work. (The same oil injectors fit through years '84-'92.)

 

On a 12A is there an injector on the actual rotor housing? I was thinking of just plugging the old lines off the OMP that go to the intake manifold and just making a metal block off plate to put where the actual pump was. No?

 

My engine is a 79 12A. Getting block-off plate from Atkins.

 

Well what are the plug holes you were speaking of? For injectors? I'm a little confused now on what to do. lol

 

Link to Atkins plate?

Doh never mind http://atkinsrotary.com/store/79-85-...97-10-602.html

For that price I may as well buy it from there.

 

do you mean the brass fittings on the carb?

 

If that was directed to me yeah. lol
