Turns out I have a broken Piston ring, so I guess that's the end of the SHO. I had it less than a year too and I loved driving it...

So what are you going to do with the car? Did someone run a compression check?

Yeah, I still have it in the shop. I'm not sure what I'm going to do yet, I may end up junking it. I can't put it back on the street, the city has been watching it since it sat for so long.

Seriously....Jamal, give me the opportunity to buy it back if you plan on getting rid of it.

The guy at the shop had mentioned oil pressure. If I do get rid of it, Ken, you will be the first to know. I'm looking to get a new 3.2L engine (even though everyone around me thinks I'm crazy.) but it's getting harder to keep a dead car parked in one spot for long, without the city taking notice.

Rod bearings were done on that motor at 160k. Did the shop do. Compression test? Im just curious how they came to the conclusion that the piston was cracked. It takes A LOT of heat to crack a piston.

There's gotta be a SHO guy in the area that can have a look at it. If it's a single broken piston ring, it should still start and run...it would make quite a racket at idle, but I'd think it would start up, no problem.

I've definitely started these SHOs with more than 1 plug wire diconnected. I've even started one missing a spark plug before. One broken piston will not stop the combustion process in the other 5 holes.

It should take a shop about 10 minutes to pull the intake and another 10 minutes pop off the valve covers so that the valvetrain can be inspected. My guess is that they did a compression test, saw the low number and decided they'd rather not mess with it so they named the worst possible cause.

Tell them that you think there's a shim that popped out of it's bucket and it's probably laying in the head.

A cracked piston ring would cause the charge to go into the crank case, where it would escape through the crank case ventilation system.

A spit shim is probably the result of a valve that got stuck open. If it was an intake valve, the charge would be shot back into the intake where it could cause all kinds of havoc with the combustion process of the other 5 holes.

I guess it doesn't matter...if you've got a stuck valve and a spit shim, or a cracked piston, the engine should be replaced.

I'm not 100% sure if they did a compression, I was at work when they called me and told me the news about the piston ring. They claimed to have done it.

What is a good place to buy smoked GTS headlight covers?

Hey thanks for working on the car, Scott, Drew. Saved me some cash and even the car from me getting rid of it over a clogged up fuel system. I am going to have a talk with that BP shop about the difference between fuel injectors and a cracked piston ring.

Maybe someone should explain the difference between premium unleaded and diesel fuel to you.
