(Not*) Mediocre 242

Wow. That's impressive. One thing I have seen is alot of time failures like that is the event that caused the main failure happens earlier and takes some cycles to propagate to something like this.

That’s what I told him as well, I’d guess it’s a previous injury that finally let go.

Bummer but also kind of a badge of honor for pushing it a lot further than most.

Yeah, I'm sure that's what it was. I dug a little bit and found the cylinder 1 spark plug is toast; cylinder 1 rod or piston likely failed. It's gonna be bad when I open it up.

Well, if anyone wants some redblock performance parts I think I'm going to part it out and swap in a non redblock. I worry this will keep happening with the power I'm looking for. Cylinder 1 of the head is probably cooked, but might be weldable and the spark plug threads can surely be fixed. We'll see. Here's a quick list of stuff I can think of:

NIW manifold
Ported KL racing manifold
Domiworks 8HP adapter kit
RSI tubular manifold with provisions for EGT and EMAP
Baffled/enlarged oil pan
ATI crank damper and serpentine pulley setup (lightly used lol)
Mil spec wiring harness (I can help you convert it to fit your ECU. It's pinned to fit my Motec, but that's easily changeable)
ASS engine mounts

If you want info about anything on my car or want everything to support a big power 8v (🤞) let me know and I'm happy to answer any questions. I've got to at least try to fund a new engine purchase.

Noooooo. Bummer to see that Tate. This has been my favorite redblock build to follow.

What are you thinking of for power plant? Keeping it Volvo?

I'm thinking 2jz. It'll be expensive but I'm probably just gonna keep the internals stock for now. It should be ok around 800 hp.

Was this the 531 head you just put on? What a bummer! Im really saddened to see this.

Yeah unfortunately.

I put a borescope down the cylinder 1 spark plug hole and it did not look good. I saw the back side of some bolt and nothing that resembled a piston or cylinder wall.

Selling the damaged bits or mounting them on the wall?
 
Dang that is gnarly! Sorry to see such a wild failure dude! I was looking forward to seeing the dyno results.

If you part out I'll definitely scoop some parts up
 
More bad news for me. Cylinder 1 combustion chamber is going to be ugly. I found piston/rod bits in the intake and exhaust manifolds. My turbine wheel took some damage, and the turbo going to need to be rebuilt; at least I know a guy for that.

I guess 8ish years between 400-600ish whp is the limit for RSI rods/pistons.

What if valve failed first?
