Need to check on the insurance part. If all you have is liability, you may be on your own here. Sounds like you have something more serious than a headgasket, hope not, but very likely.

Mike, I had a 944 Turbo, and I did what skip said to do. Drill 1" holes into the intake tube's underside, this prevents water from entering your intake. Sal

Joe Isuzu wasn't that the guy who couldn't say Cheverlay?

Quick update,

last night, filled reservoir with water and ran motor. Did not notice any mixing with oil, but engine ran poorly. Bogged down when I gave it gas, and kinda sounded like a rod was wacky. I think I definitely need to perform a compression check.

As to my insurance, I have minimum coverage.

Skip, I too had an Impuse. Mine was an 84 Turbo. Neat little car, double wishbones, 4 whl discs, intercooled turbo.

Dunno what steps to take next.

Thanks again for everyone's help.

I am just curious but is it possible that he bent a valve instead of a connecting rod?

smart money is on the rod

If the engine hydrolocked, chances are the rod is bent, not the valve..

Reason why valve doesnt break.

Valve closed, it's supported. Able to withstand the pressure of combustion right.

Valve open, either the exhaust manifold is present, or intake manifold. So rather than bend the valve water will go around and fill either plenum.

Rod bends on compresion stroke when valves are closed.

What about the old broken piston/piston ring, hydro lock does this the boats all the time.

When an engine has ingested water it's a crapshoot to guess what damage was done (except in an extreme case of "compound fracture"). If the engine is not running right, and especially if there is an undetermined noise, do not run the engine any more. Tear it down, find the problem, fix it or abandon it... it will not heal itself and you are compounding what could be a reversible problem.

FWIW, the engine is not hydrolocked - if it were, it would not run. Being hydrolocked infers that the engine is locked, unuseable, and most certainly very broken.

Good Luck!

Right, the more you run it the worse it gets. I wouldn't have drive it home.

Hey there,

Just an update... Its looking like I have blown the head gasket. I took my car to a local race shop that prepares SCCA 944s. The mechanic says that the gasket was in bad shape to begin with, and by ingesting the water just helped it to blow out. Apparently the seal around #4 cyl was really bad and completely toasted. Also said the there are little bits of paper from the gasket in the motor, but should clean up nicely. Also said the head/valves and the block look fine, and doesnt expect to find any other problems

Hopefully, I will have the car back in about a week. Will post again when I find out more.

Take care,

Mike

yeah, sounds like a head gasket or cracked head/block. more likely block if something's cracked, due to cool water on a hot engine/shock cooling. now, do what they said and contact your insurance about repairs, if you're on your own, start with the headgasket, and if its plainly blown (sounds like it, motor will run poorly and shoot white smoke if you're burning your coolant) you'll certainly be in for a less difficult fix than a new/rebuilt engine block.

good luck,
-Michael-

Lucky you!

I knew a guy who used to restore flooded cars. When they did the engine, he'd fill it with diesel oil (it absorbs water) then refill it with regular oil after it sat for a day and then drained for a day, then possibly refill it a second time if needed. Just let it drain real good between refills.
