I want it gone becuse i broke the lines to it, it leaks and i would rather premix.Does any one have a write up or pic's? Isint it better to pre mix (clean /burnable oil insted of dirty crank case oil)? Less parts to fail.

If you want to use a block off plate, you have to remove the pump and fabricate one yourself. I don't think there's a tutorial on this one. Rotary7s made one, and is thinking of making them for sale to forum members, hit him up with a PM and see what happens.
However, if the type of driving you're doing is "daily driving with occasional racing", just rebuild the omp with a rebuild kit from Lowe's Automotive
http://www.loweperformance.com/
It's $10USD, plus the cost of some mineral spirits to clean it with. There IS a tutorial (actually two) on how to do that here:
http://www.godofredo.com/mound/3-11-03.html
and here:
http://www.mazspeed.com/oilmeteringpump.htm
For ten dollars and one night&day's worth of work (you soak it overnight, rebuild it the next day), you have a damn good deal for something as critical as the Oil Metering Pump.
In case you aren't sure what the OMP really does, it's a small pump that takes oil from the oil pan and injects it into the intake manifold (or carb, depending on your model) to help lubricate the engine's apex seals. If you remove this pump, and don't find another way to lubricate those seals, you can say goodbye to your engine, because it will sieze up on you.
One way some people get around this is to mix two-stroke oil into their gas when they fuel up at a 100:1 ratio (roughly). This is pre-mixing. It assures that you get enough lube, but it'll either cause you to run rich at low RPM, or not have enough lube at high RMP.
Some people say that because you use less gas (and thus less oil) at low RPMs, and more gas (thus more oil) at high RPMs, it works just fine... but the reality is the mix will be *slightly* unbalanced. It's nothing to worry about, many of the people on here pre-mix for their daily driver cars, but my optimal solution is this:
http://www.rotaryaviation.com/oil_in...p_adaptors.htm
keep the OMP, add the little adapter above, and boom, you have a 2-stroke resivoir to feed the OMP. This would be optimal because two-stroke oil is [I]designed[I] to be burnt off, and leave behind a lubricant as a by-product, unlike the oil from your oil pan, which is not designed to burn. In the case of synthetics, it's even designed *not* to burn, so you should never use synthetics.
*takes a breath* alright, you probably knew most of that info, but at the very least, this makes the thread a good reference for the next person who searches for
OMP blockoff (block-off) plate
OMP rebuild
two-stroke resivoir
OMP adapter
or anything else I've mentioned
Have a great day, I'm off to finish my brakes

There's a thread in the 2nd gen forum about this. Most would apply to a first gen--except the S5 OMP which is electric.
Tells what to do and has lots of juicy arguments for and against premix.
I'm still undecided by need to make a decision soon for the TII engine.
