I have a 84-SE, I see there is heavy oil build up on the oil metering pump and on the oil pan. Is it coming form the pump or pan? Or are the hoses from the oil metering pump leaking? https://www.nopistons.com/forums/pub...IR#>/dunno.gif Does anyone know?

its prolly the metering oil pump. it leaks thru the shaft



mike

its the pump its self or just need to change the gasket or O ring?

it could be either one, clean it off and see



mike

if it leaks thru the shaft, I need to get new?

yup



mike

know where i can get one cheap

Its hard to say where to find a shaft like that for cheap.If mine starts doing that the OMP is getting pulled off and a block off plate will be in its place.

block off plate!.....then it would need to be premix then right?

yes, if you remove the metering pump, you need to pre-mix



mike

how do you do that?...... is it better!

If I can remember correctly its 8oz of 2 stroke oil for every 15liters of gas.Its supposed to be just as good and will save your engine if the oil pump gives out on you.I might do it once this pump gives troubles.

I think thats alot of hassel just to put gas in, this car will be daily driver and dont think i wanna do that every time i gas up. I do what some performance, enough to where i know i can step on the gas and it will pull. I will ugrade the suspension though, odering all the busings from Mazdatrix. looking for sturts and shocks. Also thinking of going w/ the race spring thst mazdatrix is selling. Its a 2.5" drop. Think thats to low?

For parts to rebuild your Oil Metering Pump call Mike Lowe. He'll hook ya up with everything you need plus instructions on how to do it. I rebuilt mine and it was quite easy to do.

or you can just ask around and find someone who's switched to premix that can send you their old one... make sure it's the shaft thats leaking before you go replacing it though. there are alot of areas with potential for leaks.

thanks for the info....I already took it out to see if it was leaking and did see some fresh oil around the linkage and spring area of the shaft, did not find any leaks around the the o ring, cleaned it off and put back together and ran for awhile and did not see any leaks. should I run it longer and drive around.

I order the reseal kit from Lowes Performace and it does come with instrction on how to rebulid the OMP. It was easy to take the OMP apart and put in all the new o-rings in . It works great, just like new. It cost $21.00 for a reseal kit for my 84 -SE. Thought I was going to have to spend the $200 for the NEW OMP that I don't have. Thanks for the info Inittab.
