Help please, I blew my motor and need to plan the rebuild

Spooler

That just sucks. At least you know.

It's under the front cover above the oil pump.

Knowing what I know now I'd probably recommend replacing the OEM oil gears with the Nismo steel ones and upgrading that gasket when replacing the timing chain at an early interval maybe 60k???

My timing chain was in good shape.

...and of course the distributer cap.

Don't forget the plug wires, points, condenser, and distributor rotor. Also don't forget to pull the vacuum line off the vacuum advance and plug it when you set the timing.


The younger guys probability don't know what we are talking about.

This motor is pretty cool. A lot of parts but very cool.

Lots of parts to make a big shrapnel grenade?

Head gasket leak and oil leak all at low miles. Must really have bad luck, if this were a vw/Audi I would say normal.

I'm curious how z1 etc is going about rebuilding these blocks with boring and honing aluminum walls. I haven't kept up on my engine building but they usually have a hard coating for wear and if rings leak etc the manufacturer just replaces the piston and rings but no re honing is done (at dealer level). Curious.

Ape Factory

I'm guessing there's a long and storied history with the oil galley gasket failing if EPS is actually making a gasket set to replace OEM. I was aware of the pre-2012 issues with the gasket that fails under rear timing cover but not this one. Many documented cases of the rear gasket failing on the G37 forum.

Well it's ugly when it happens and honestly I'm glad it happened at the track where I had a lot of ready help around. This could have gone on the freeway and I would have been screwed.

Were the phillips heads hand tight? Eps told me that's an issue. They back out and the gasket blows out. They need safety wired!

Shame a damn gasket will do that much damage.
Oil pump gear still in one piece.

The crank is still good. A little grinding on it will make it good as new.

Some JB Weld to fill in the hole on the block. And it will be good for another couple of trackdays.

What you can do with the piston, rod, and pieces. Is to encase them in clear poly, and use it as a paper weight or bookend.
