Why are you taking what im saying out of context? i never said anything about it running on a broken seal (BTW: There have been cases where a motor has had a broken seal and still ran.. like ****... but it ran). honestly, I dont care if god himself came down from the heavens and pissed in a combustion chamber, once that chamber goes to compress something is going to break (assuming it is filled and the water has no where to escape). Water does not compress.

LOL...it's all good, man. I think I understand what you're saying. Those hydrolocked piston engines both ingested a lot of water...usually at full throttle. Are you saying that broken apex seals is what would probably happen if a rotary ingested a comparable amount of water? That makes more sense. Your posts made it sound like you were trying to say that any amount of water can do that type of damage.

At least in the piston engines, I don't think so.
Just last week I took my wife's car into the dealer on a minor warranty issue (plastic end tank of the radiator split...go figure ). At that same time, I mentioned a slight ticking sound that I had noticed her car had begun making in the last month or so. Although the engine is a NORTHSTAR V8, I likened the ticking as sounding similar to a bad hydraulic lifter on my antique car. The service tech immediately suspected that it was carbon build-up in the combustion chamber, apparently not uncommon problem with this engine when it's driven "conservatively". As I watched, they did the water ingestion and cleared it right up. While I didn't notice any power increase, the noise was gone and it now seems to idle a bit smoother.

hmmm... worth a shot.. Im going to try the sea foam trick though

ac delco makes top engine cleaner that is specificaly designed to not attack rubber or plastics. it does a number on carbon deposits though. that said water does a nice job also

guess it really can't hurt to try.... ill do the sea foam then water...see what happens.

i did the sea foam, cleaned up my idle. im sure water is just as or more effective. note: use distilled water. tap water contains minerals and chemicals and such which may not be engine friendly. seriously.

My roommate second semester freshman year at college worked at a Caddy dealership during the summer as a porter, and he said that they got Northstar powered cars in there all the time for that problem. He said that they used some sort of chemical to clean out the carbon buildups, and the reason was two fold, one that people drive their cars conservatively, like you said, and that Caddilac recommended one too many quarts of oil, so the engines were burning the excess oil, causing the buildups.

BUddy of mine has a North star and had to change the O2 sensor many times .

and the northstar leaks and pulls head bolts like it is it's job. batman there is no reason to go through several o2 sensors , there are 4, could be a fuel prob or the maf. there is a fuel rail recall for alot of years and the fpr fail all the time. on topic the top engine cleaner does a nice job also
