Locked up engine

It is/was a comp engine.

The heads were built by Element Tuning with Ferrea big valve components. The spring kit sells for over $900 and valves range from $60-$70 each. I realize the valves in #2 are probably/maybe/most likely toast but the springs and the rest of the valves (and bank 1 head) should be fine.

I don't know if anything in the bottom end is worth anything.

When pulling the heads off, should I try and keep the rockers and shims matched?

I don’t think I would worry about keeping rockers and shims matched too much but putting them in a bag and labeling where the came from isn’t a bad idea. Heads can be repaired so I would try to salvage what you can as it may be worth something to someone. That head package is not cheap and a repair is much cheaper than having it all done from scratch.

Meh. Those shims are going to be all mix-&-match once you start cutting valve seats, lapping, blah blah... MSG is on point. Those heads are worth way more as complete packages. Maybe repair, spruce up... I dunno. I'm amazed at people that are good at wheeling and dealing. I always get burned unless I pay retail for new shit, and I just give away what I don't need.

Noob question here: This engine has ARP head studs. Yesterday, I was trying to take the nuts off to get the heads off but they were really really tight. Much tighter than a wheel lug and much tighter that the old chevys that I worked on years ago.

I don't know what is normal for these engines. Do I get on it with a 6' cheater bar and go for it?

A buddy said it might have been caused by detonation. To my untrained
eye, it looks like the piston just f'ing broke.

As I posted earlier, these are Element Tuning big valve heads. As a noob, I have no idea how much it would cost to repair this kind of damage. The valves (-4) and springs are around $1800. Plus bronze guides.

I didn't reply because I don't know about the FA. Did you just send it?

Yeah, I found a guy on YouTube taking the heads off of a WRX. He used a looonnnggg breaker bar and lots of ugga duggas.

I’d try sending an email to Headgames. I bet it is repairable.

Piston and sleeve look to be mildly annoyed for some reasons.

"Nope. Not gonna. Hangry."

How many miles/hours were on this expensive motor? I don't ever remember seeing a piston in that many pieces. Yikes!

Only about 25k. I had hoped that my expensive motor would last longer that a stock one, but me and my wallet were wrong.

Good idea. I, myself, am not interested in keeping them. I'll probably put in the classified ads at a bargain price. Is it a $500 repair or $1000? It might be easier for someone (who know what they are doing) just to strip them for parts.

They are really tight. It’s really tough to get them off without knocking over the engine stand.


This failure looks kind of reminiscent of a high RPM single dirt bike engine. When they started going to 4 strokes for MX I saw a similar looking failures lot. Piston slaps around and breaks the skirt and wedges itself in cylinder and the rod beats it apart.

That'll buff out.
