Pre-mix / block off plate/ dimes/ ?????????
Ok, yes I searched but couldn't find it and don't have much time. I'm gonna pre-mix on my turbo motor. I'm concerned with just the block off plate, the shaft that normally runs the OMP will still spin and either wear on the block off plate, or move out towards the block off plate and the gear will not mesh right inside the motor and wear something out in there.
I heard the whole just stick 2 dimes in there behind the block off plate trick but as I see it, it will still be metal on metal grinding (shaft vs dimes). What is the correct way to do this. My motor is already back together and I forgot to take that gear off of the omp shaft that sits in the front cover.
My plan was maybe to leave the omp on there but take out the guts of it so it doesn't try and pump oil and screw 4 bolts in where the oil lines usually come from.
Any suggestions, am I incorrect in thinking that the dime thing might cause problems later on? Metal shavings ect?
thanks

I have had mine blocked off for aprox. 20K miles and when i pulled it off there was no noticeable wear at all, infact i do belive the silicone was still around where the OMP shaft would touch. I didnt use dimes.

I used the four OEM banjo bolts (just without the OMP lines) and tightened them down all the way. Then I used 4 bolts that I matched the threads to the stock OMP injection 'holes' and used some copper crush washers and tightened them down in the top of the rotor housings. Simple, no problems (thus far) and pretty much free and easy.
Don't know if it's the "proper" way, but whatever, it works great.

My worry was that the shaft does move in there and that it might spin against the plate and cause metal shavings that might make their way back along the sides of the shaft and into the engine. Everyone seems to have no problems with this though.

There is a roll pin behind the front cover that holds that shaft in roughly the same position. There is some give, but not enough to even come close to your block off plate.

With the gear and all totally intact, the shaft CAN still come out past where the block off plate would be. It can come out about 1/8 inch or so past the front cover, it's deffinately enough to make contact. Whether there can be any long term damage, I dunno. The best way is to remove the gear from the inside then there would be no spinning but my motor is back together and I don't want to take it apart.
