Eng Crapped

[FULL-THROTTLE]

Bummer,

I crapped an engine today, 98 challenger w/twin 787's R/side locked up, it is odd I was towing a tube and throttled back to idle then shut down both engines, r/side wouldn't start, limped home, Aft plug gap was completely closed and apparently hit by the piston, eng will rotate 3/4 the way around left and right but not all the way around you can hear a significant clunk when it comes to a stop, I put a screwdriver on the top of each piston and they both move freely??????? I assume the rod bearing let go.
Luckily it is a 1 year old SBT rebuild put in at a local shop so it is warrantied, the shop takes forever to do this kind of work, I am probably going to do the change over myself if SBT will honor the warranty if I do the work, I am a licensed aircraft mechanic and feel completely comfortable doing it.

Bummer, the weather is great and 4th of July is next weekend.

SBT don't fail me now

[FULL-THROTTLE]

Found the Problem

I pulled the engine and the rave valve is missing both outer edges, I can see some of the pieces mushed up against the head. It is on its way to SBT tomorrow, luckily it is still under warranty. I guess I'll have to sit on the deck and drink beer instead of water skiing over the 4th, still a successful weekend.

P.S. The folks at SBT have been great helping out with the warranty and shipping info.

At least its still under warranty...that's a good thing to think about while drinking beer...
