You think the dealer wouldn't warranty their own work? They fixed the engine and said it would be OK. If it died a short time later I'd be holding them to their statement.

When I had my leak down test on my blown engine the good cylinders were exactly 185 not more or less.

Well, I initially had the car towed to the dealership after hydrolocking my engine in a rainstorm. They proceeded to get the water out of the cylinders. Afterwards they performed a compression test and the numbers I posted above are what they found. They said the numbers were okay, but I still think the water did some damage that the dealer did not notice. After all, they didn't even open up the darn block. Everyone I've talked to said my compression shouldn't vary that much. Also I've read about a bmw being hydrolocked, dealer diagnosing it as okay, then 20K miles later the engine was gone. It happened to be a piston a millimeter or two off spec. Oh well.

This slight bend in the rod would drop the compression in the bad cylinders because it would no longer reach max stroke at the top of the cylinder. Possibly you had a really good motor with 200 across the board before the hydrolock incident.

hey btw this is kind of OT but how do you like those mines test pipes?
