Man, I'd really consider an aluminum bung on the pan if you already have it off.

I woke up in a cold sweat last night having a nightmare about a tranny. Not the usual kind, but one of my transmission breaking because I'm an idiot who wants too much. After reading and searching a bit more, I'm scaling back the trubo goals to the 6758 with probably a conservative tune. I'd rather drive the car than have a dyno queen.

I don't think that's enough RTV on the oil pump - it's going to leak past the empty areas around the bolt holes.

I used the paper gasket in addition to the RTV, is that alright?

I dont think you can run a gasket on pumps that have the oring on the feed to the block, only rtv. Earlier pumps didnt have a recess for the oring and they were to be used with a gasket.

Thanks for pointing that out. I just searched a bit more and found that another user on mnet asked about the same thing. 1.6 engines didn't use the oring and the later 1.8s didn't use the gasket. I'll go back tomorrow and remove the gasket and put more RTV on it. And I had just gotten the oil pan back on today lol. Gonna have to re-seal that flange too, but there's the right way and the wrong way.

Went back in, removed the paper gasket and RTV'd the oil pump much better this time.

Head gasket in place, studs in, head on torqued to 65 ft/lbs

I know the feeling. Im gonna have to crack open my freshly sealed oil pan and mbsp to plug the oil jets after learning about some issues with them and builds with forged pistons that have oil drain back holes.

All Miatas run the o-ring. All of them (well, 89-05). Believe me, I had a 1.6, I left out the o-ring, you need it.

You could have left the paper gasket in, but if you're RTV'ing a gasket on both sides to make it properly seal, you don't need the gasket. So it was removed for later engines.

I RTV'd the heck out of it second time around, it should be good. These rtv tubes are annoying, trying to get it out i had to roll it and then rtv started coming out of the sides. Messy af

Had that happen trying to put in an exhaust gasket once. I squeezed too hard and it blew out the back. Of course the silicone was at body temperature so I didn't realize it until I felt something goopy on my arm. That took a while to clean up...

After reading through JeffBucc's thread, I almost feel like I'm neglecting my Miata. Some day I will have the time and drive to do 50% of what he has done.

This is what we use at work exclusively. Comes with a handy tube roller that I hold on to for any future tubes. Really should bring one home for tooth paste...

One experience with this style of RTV applicator and you'll never **** around with another rollup tube again.

Not yet. Decided I'll trim some bolts when I get the hankering to pull all that back apart.

What Curly posted had me kind of perplexed. I fired up the old epc and looks like mazda went to the o-ringed pumps in '93. Heres a screenshot of '92. All pumps after that were non-gasket, according to the parts catalogue. I dont own a miata, and I am not challenging the post, just interesting none-the-less.

I come from the land of fwd BP powered cars and have had both variants of pumps
