I might have just figured out my oil leak
 

Ok anyone who went to the miata meet at steves knows i have an oil leak, the leak was anywhere from .6-1 quart per 100 miles, it only leaked at high speed/pressure, and got slung around everywhere under the hood from the crank pulley.
I thought it was the crank seal but upon disasembly all the usual shit that is slick and oily when that fails was dry and in great shape. Then i noticed a new hole in my BE oil pump i geuss they used a different housing etc.
anyway here is my 1.6 stock oil pump

and here is my new BE oilpump after i jb welded the extra bolt hole

I measured the depth of the hole and it goes damn near all the way through so I thought it was worth a shot. Once the jbweld has cured i will post an update. Thoughts etc. anyone else seen this problem?

this has been discussed... that's your leak for sure.

ahh i thought so but most of what i saw was the shit for the AC compressor bracket wich i have installed with all bolts etc. I looked for nubbins thread but i didnt find it thx scot.

im the king of search.

so should i take out the jb weld or do you think i will be ok?

well wtf did no one have any insight? Like i said before this is in the same area but it is a bolt hole that my stock shit did not have and all the bolts that i ran on my stock shit are installed. So lumping me into the mess of people who just didnt put there shit back together with all the bolts they needed to get the job done is BS. Seriuslly why do i even ask questions if you guys wont take what the fuck i post serius?

It appears that I'm almost 12 hours too late, but I would've gone and found a bolt of the appropriate length and put that in there. Non-AC equipped Miatas have a shorter bolt in that place.

You're effectively shorting yourself some clamping load (or at least uniformity) on the oil pump to engine block seal.

AC equiped all the time and bolts properly installed and torqued. Little shit like this drives me crazy.

Ah, different hole than what I thought. Mine has a press-fit plug in that hole. JB-weld should be fine then. I was working on sealing up my oil pan and pump today on the bench but found out I didn't have the oil pump o-ring or the pickup tube gasket. FML.

bryce ty so much that was all i wanted was for someone to actualy look at the problem. I am just as savvy as the next .net user but an extra set of eyes actualy looking at the situation helps a ton, it's not like i have 10 turbo miatas within a 50 mile radius that i eat lunch with every day.

Has that little crack always been there on the end of the crankshaft?

Yup, I was losing about a quart every 1k miles through that same hole. Stuck the appropriate bolt in there and I'm leak free.

there is a crack where? i didnt even notice one tell me where, and i will go back out to make sure it isnt a trick of the light. Or left over loctite etc

Just pulling your chain. :D

Joe made a funny! Hahahaha

Ok so after predigous amounts of jbweld, locktite, and, time etc the car still leaks oil i verified that it is comming out from beneath the crank pulley so at this point im probly gonna be pulling the motor and redoing the pan. :yippee: you gotta love this shit. :crx:

ouch man. good luck. just have someone weld that ho up once and for all

I know that sucks! I ended up buying a 2.0 to fix my leak. You might as well reseal the oil pump while you have the pan off.

Lord of the Gays.
