So. What Do We Think About Fixing This?

I finally got a good look at my J2000’s block today, and the reason it was in pieces became readily apparent.

I’m hoping I can fix it by machining it down and maybe running a shim gasket. There doesn’t appear to be any other cracking or anything, just that damage. I’m not sure what even would have caused it, but the head gasket was blown right there as well.

shaving 10 mil down will raise compression. That means power! that means fast! What an excuse!!

It’s not a repair, and it’s opportunity!

Can’t spell “Job well done” without JB Weld

Looks like a failed gasket led to some sort of detonation event - or the detonation caused the gasket and nearby block area to fail. In any case you could add some material via welding then gring it down to factory spec.

As the othes commented this is an opportunity for some improvements to correct a cost-compromised factory build.

There’s a couple ways to fix this, depending on your budget and goals for the engine. I would suggest talking about your options with a machinist who's familiar with this motor.

1. Simple machining. That’s a lot to take off though. Are shim gaskets readily available? Cometic probably...? Just be careful about calculating compression and checking piston clearance. This should all be a cake walk for any competent machinist.

2. Re-sleeve it. Expensive. But you clearly need at least a real good hone anyways. Might be a good opportunity to increase bore.

3. O-ring it. Usually done for extremely high boost race engines where gaskets tend to blow out under pressure.

Machining it was my thought. I want to spend very little on the motor, and if it works pretty good that’s good enough. Shim gaskets are available for it, I’m also not averse to having custom gaskets made if necessary. It’s a cheap motor, but it’s proving to be a hard motor to find a replacement for...if I could find one it would be about a hundred bucks, but all the Sunbirds, Skyhawks, and Firenzas they powered have long since become Hyundais.
