My 99 Blaster has oil leaking from something under the Oil Injector Pump Plastic Housing (black plastic case).

I removed the black plastic housing and could see the oil injector pump, but I cannot see where it is leaking since there is oil on everything.

I removed the two screws that hold the actual pump up into the bottom of the motor and pulled the pump off. This is where it began to get interesting.

I am hoping that the leak is due to a failed gasket between the pump and the engine block. Is it "OK" that I removed these two screws and pulled the pump away from the engine?

I noticed that a silver rod with threads on it is sticking out of the engine and this rod went into the Oil Injector Pump when it was attached. Can I just slide the pump back onto this after replacing the gasket, or does something have to be lined up?

Also, on the pump was a rubber boot that covered another (smaller) threaded rod that stuck up out of the top of the oil injector pump. This boot was full of oil. Should I put some hi-temp silicone on the inside of this boot when I reinstall everything? This would keep the oil from leaking out of it if the problem is here?

Did I mess up any adjustments or timing of the oil injector pump by removing it? If I did, how do I make it right? If I didn't, exactly where is the adjustment (if any) for the pump made?

Last question...Do I have to run Yamalube Injector Oil or will any Injector Oil work? I also have a Sport 400 and would like to share the Polaris Brand Premium Injector Oil between the Blaster and Sport 400 so I have one less bottle to carry around and keep track of.

I was also considering putting the same 2-stroke oil I run in my Banshee in the Blaster Oil Injector. I use Power Plus and according to the bottle, this can be used by either Pre-Mix or Oil Injectors.

I know this is alot of info, but helppppp!!!!

Thanks!

 

nac's sells block off kit where you can totally get rid of it.just mix your gas. later

 

I bought a block off kit for 12.99 on ebay that would be less of a head ach then waiting for it to lock your motor up.
