i already know hte answer to this, but homeboy doesn't seem to believe me. anyone wanna chime in?

thanks

 

I have an original Mazda 13B-REW in my garage, it has grey or black sealant goop squeezed out between the housings near the oil pan.

It also looks like the lower intake manifold gasket it paper. I don't know when Mazda stopped using the paper gaskets but it was at least a few years ago.

I don't see any evidence of it being rebuilt from the pics.

 

OF course it has, the tension bolts are numbered. You don't pull a flexplate to write **** on tension bolts for your health, you only do it when y ou want to open one up.

ON that note, I won a REW longblock core on ebay a few weeks back. The thing arrived on a pallet about like yours. I knew something was up when it had cosmo twins on it. Come to find out someone took 2 motors and made one out of it. Half the accessories were missing, half were there, none of it was connected, as if someone just bolted some leftover stuff together.

Turns out it had cosmo twins and manifold, rew intake, rew secondary rail with injectors, cosmo lower rail with no injectors, about 1/3 of a vacuum rack and solenoids, a cut US rew wiring harness (they cut off the tranny wires), and a cosmo oil filler neck. The block was cosmo rotorhousings, cosmo front and INT plate, rew rear plate, and cosmo/rew rotors. It had been put back together with some of the coolant seals missing altogether.

I have no clue what in the **** they were trying to accomplish with that deal.

Looks like you got a raw deal, too. He's right in the fact that the top hole/ear doesnt really matter, however what about the other broken one by the OPSU, that *is* necessary to bolt up either trans?

 

Oh, and mazda used either a clear or white sealant, never black. That's definitely aftermarket.

 

i know the top bolt hole isn't going to be used IF it's bolted to a manual tranny, but the fact that it's broken shows either abuse, stupidity, or just plain clumsiness---like the engine was dropped at one point in time. in any case, i most definately should have been made aware of that beforehand.

and if the tension bolts were actually torqued in that order, i want nothing to do with that motor.

thanks for the replies. now i just gotta try to get a refund out of this guy....good luck to me!

 

I double checked my motor, the sealant appeared dark grey but when wiped off it is actually light grey, almost white.

 

as far as i know, the factory never used permatex ultra black

 

My top bolt hole was broken and the motor had never been out of the car.....

 

Sometimes people try to use the top bolt holes to pull a stubborn trans up against the engine during a clutch job or auto rebuild. OR, they cross thread a bolt or use the wrong bolt. so it's not terribly uncommon to see one broken off. Now, you don't *want* to see a broken off ear, but it doesnt mean it can't be used. The manual trans uses 6 and the 93+ auto trans uses 7 bolt holes, but in reality 4 of these will hold a trans with no issue at all.

 

i'm planning on race gas and a couple 500+ whp dyno pulls.
i like ALL the bolts to be in place for that kind of stuff.

but i know what you're saying and i agree for the most part--i'm more pissed about the shady way the guy is dealing, the lies, hiding things, etc than i am about the rear iron in and of itself.

if it were only the top bolt and he came out and said oh yea dood, i dropped it during the rebuild, or whatever, it wouldn't have been all THAT big of a deal. but he conceiled it, then lied about it, then blamed the shipping company , etc....

 

fwiw, I have a couple of spare back irons for an rew 5sp if you need. You can port match the runner without much issue.

 

i appreciate that, but one of the reasons i like the cosmo so much is the mounts don't go through the pan--less chance of leakage over time.

thanks anyways though.

 

well no luck with the refund...
i guess this one's gonna end up in court. that's just ******* sad.
