Default 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 **** 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?

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 **** did not have and all the bolts that i ran on my stock **** are installed. So lumping me into the mess of people who just didnt put there **** 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 **** 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 **** 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.

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.
