so i have my block off plate now. so i can finally get rid of my always leaking problematic OMP.



im set on the protek-R by pettit racing for my additive. anyone have experience with this product?



know of any that are better or equal for less money?



oh yeah...what thread size and pitch is the oil injectors? so i can block them off.

I used to know. I blocked mine off forever ago though.



It's NF (Normal Fine) thread pitch, and I think M10. Not positive anymore though.



Hopefully someone can answer this quicker than me, but I can dig up the thread pitch and size next time I'm working on my crap.

M10X1.0 thread pitch I believe. Metric doesn't have coarse and fine. They measure distance between threads in mm so if its xxX1.0 its 1mm per thread if its xxX1.5 its 1.5mm between threads. I hope that clears some things up. The bolts are relatively fine in their thread pitch.

Whoops. I deal with SAE all day long, I got mixed up. 1.0 is comparable to an SAE NF and 1.5 to NC, no? https://www.nopistons.com/forums/pub...DIR#>/wink.gif

You'll be fine with any tcw-3 2 cycle oil.
