When I had my LIM and UIM off, I broke a nipple off that vacuum spider thingy for the OMP tubes. I Plugged the hole, and used a vacuum T off one of the other tubes to make it work. But how do I know if the system is working? And the Haynes book said something about blowing through the oil metering nozzles to see if they work...I wasn't too sure if I did that correctly either, but I think air went through both ways.

I have a couple of those spyders, send me some cash for shippin and I'll send it to you. What all do you need??

your supposed to be able to blow, not suck, I'm not sure if your supposed to put your fingers over the wholes on the side for that test tho.



In the hayes manual they say for you to remove the injectors then run at idle ???? Sounds like it is more work than it is worth, but i guess removing the injector to physically see that oil is dripping is the only true way to know that oil is being injected.



I don't trust that ****, so I'm runnin premix now. That's all i need is to do all this damn work and have something like that blow my motor.



you can have the whole setup if you want it, it's a paper weight to me

I thought you were supposed to suck on them to be sure that they held a vaccuum

Thats why you run premix, no more guessing if the apex seals are getting oil https://www.nopistons.com/forums/pub...#>/biggrin.png https://www.nopistons.com/forums/pub...R#>/tongue.png

hm. good idea. i dont know what to do w/ all those extra nipples lying around.



premix, eh? i'm running a blowthrough carbeurator turbo setup. i may just do that jsut to be sure.



would having working omp lines, as WELL as premix, do any damage??



thanks

all of that oil might foul your plugs, you can run a lesser amount of 2 cycle oil than normal. That's better than the stock setup.



Hell w/ your setup it wouldn't take 20 minutes to remove and plug your oil injectors, what are you waiting for??



I recommend amsoil 100:1 premix. It's very good tho, very concentrated, I'd run a high ratio that you would with a lesser brand.
