What do you need to do this? why do it?
thanks

I generaly need a Funnel to do it correclty. I do it because my OPM is not connected.

The reason I do it on my TII, is because it dirties the oil very quickly, and I do not want that crap injected into my housings. Plus, theoretically misting rotors/housings with oil through the injectors should be better than dribbling it with the MOP system. Not sure how this applies to carbed systems.

I don't premix on my -SE.

Yes if you didnt know, these cars have metering oil pumps which pumps small amounts of your crankcase oil up right into the carb to lube internals(yours is carb right-84 gsl?)

You can take off the MOP, make a blockoof plate(pretty easy), plug the carb, then just mix 1 ounce per gallon of 2-cycle oil or MMO.

OMP, MOP?
Where are these at, pics maybe?

Thanks.

MOP

Bet his ring finger was just faster then his pointer finger.


The OMP, is on the front passenger side of the engine, It has 2 or 4 clear plastic lines comming out of it.

Mazda calls it the Metering Oil Pump

OHHH, Still funny to call something on these cars a MOP.

In a high-performance application you want to premix to keep from blowing an engine if the oil pump quits. 2-cycle oil is the least volitile. Of the 2-cycles, I prefer Lucas' Semi-Synthetic. The Wal-Mart stuff will work in a pinch (and is cheaper for DD applications).

RotaryRyan

Yeah i usually call it the OMP cuz everyone else does. But i decided to call it the correct MOP this time

sixstar

And where do I need to block it off at, how to block it off? pics would help alot.
thanks

The MOP is mounted on the front cover directly below the inlet pipe for the water pump. Generally you will see some lines creeping up the side of the engine towards the carb, or under the UIM for FI cars.

Just remove it, then use the existing gasket as a template to cut a block-off plate for it. 1/4 inch or more aluminum is good.

The just use some of that orange sealant goop to make a gastket for it and attach the plate.

Thanks, alot of help.

I use about a quart of oil per 15 gallons, 60:1. 2 stroke oil. I normally use Pennzoil or Valvoline (though i don't like Valvoline much) all-purpose 2 stroke oil.

FB II

a whole quart per tank?

RotaryRyan

usually i run 128:1. one ounce per gallon. why do you use so much oil?

Man, I don't even run that much in my high HP TII.

RotaryRyan

What ratio do you do?

Brianhsval

I with him, A whole quart?! Damn, I have always been under the imperssion that a cap full to 16 gal. 2 cylcle of course, although I have noticed that when I do this that it doesn't want to start as easy.

In the Haynes manual, and in the book "How to modify your Rx7", it states that the stock MOP puts out approximately 250:1, and is capable of 150:1,oil rich.
The mix I use is 150:1, .85oz. per. gal., or 8.5oz. per. 10gal., or 12.3oz. per. 14.5gal., 14.5gal. is the stock capacity if you were to run it dry before filling/mixing.
In the book it also states that the Camel Light race cars(late 80's),use 100:1 ratio, and a street engine fed this ratio will experience increased deposits on the spark plugs and possible fouling.
1qt. per. tank is 58:1

RotaryRyan

Youre talking about your 85, right? It should have like a 16.5 gallon tank. 81-85 has 16.5 and earlier has 14.5. im not sure about this though.

RotaryRyan

OK, i just found the info in the haynes: In the back, in the revision for later models(81-85) it says the tank in 16.4 gallons. And before that was 14.5

sixstar

So the haynes manual will show how to block off the mop?

thanks again

RotaryRyan

I dont think the haynes wil show how. ??? im not sure.

Once you take the omp off, youll see how to block it. Just one, flat piece of metal, with two holes the correct distance apart will do. I used the MOP itself as a template thing.


Stevan, what part of the haynes are you reading from?????
