Ford 351 OMC Taking on Water (Water in oil)
The boat is EFI not carbed - but thanks.

When you look into the riser, wouldn't you see evidence of water (rust) in
the exhaust? Dave "Florida Keyz" wrote in message ... When it happend to me it was rusted risers. |

Ford 351 OMC Taking on Water (Water in oil)
Bill,
A lot of good input. I will be busy this Saturday looking in to all this. The Engine has only 212 hours on it, also a 1993. 4 years ago I did have 2 freeze plugs blow out. I replaced them with the marine type. The boat has been out several times since then. It has only been in salt water once. Rest of the time it has been lake or river ran. The oil gets changed every season, but this year water is filling up the sump fast after only running it for a hour or so. I have pumped out a couple gallons of sludge so far, and there is still more to go. My intake will be pressure tested soon for leaks. I appreciate the time. Thanks You Dave "Wildest Dream" wrote in message et... That would explain why all the piston tops are clean too, check that intake manifold out good, if it leaked to the inside of the fuel air chamber it would go to all pistons, my block froze last winter and I have the 351, 1993 and the only thing that happened was the core plugs blew out. They do have a big oil cooler on them that could be a remote possibility, I don't think it is though, my oil cooler blew out and it looked fine inside on the water and oil side (I soldered it back together, no problems) and I ride in only salt water. I didn't read what u ride in? I was going to change the risers and exhaust manifolds this yr. only about 400 hrs. on motor. If that water pump is solid on the back and has just the 2 water passages I could see a problem there, at gasket or pump housing as it looks as the back comes in contact with the oil. was it allot of water in the oil? well it sounds like u are getting allot of good remarks, GL figuring it out, I'm just a shade tree auto. mech. trying to help.

It still has an intake manifold for the air doesn't it?

Yes it does bill. But it is placed in such a manner that the water would
have to travel up hill in order to get to it. Plus a cover is over it like an umbrella. Unless the rainfall fills up the engine compartment first. There is no feasable way the water could enter through it. I believe a manifold is to blame or I have a cracked block. I'll keep you posted. Thanks again. "Wildest Dream" wrote in message . net...

Ford 351 OMC Taking on Water (Water in oil)
I have a mercruiser 4 cylinder that gets water in the oil ever season. The
boat is tarped and the engine cover is on and all entrances to the oil are blocked. My understanding is that as condensation gets in and around that area it can collect that way. Now mind you I live in Colorado so even thought the boat is covered some water will drip through the tarp and wind up in the bilge. With the cold tempters in the winter Ice will collect around where the drain hole is and block the drain hole. So as it melts and freezes there is allot of moisture in the air around the engine. I found that I just had to drain the oil and replace it . Then put some penetrating oil down the spark plug holes and let it sit for a few hours. Then it fired right up. I ran it and let it get good and warm. Shut it off and flushed out the oil again. It seems to be a spring ritual here with this boat. "DMU" wrote in message .. . Yes it does bill.

Hi,
My specific issue is this. New season - change the oil and filter. I take the boat and run it on the lake for about an hour. Come home, check oil level, and wollah - The oil is 3/4 the way up the dipstick, yellow and as thick as mud. Change the emusified oil and filter. Put new clean stuff in, take the boat back to the lake the following day, and the same thing repeats. The engine starts spitting the gunk out of the PVC tube and from here, things get nasty. I understand condensation, but when I put 6 quarts of oil in and get 2.5 gallons out, there is something wrong. It is not that humid here in central Texas. lol Sometimes I wished I still lived in Colerado Springs. sigh Dave "Greg Boyles" wrote in message . net...

The water pump was pulled today. The pump itself has no oil ports, however
the timing chain cover does, and showed some rust on the gasket. I decided to purchase a cherry picker and engine stand today. I am going on a business trip and will be back the 13th of November. The engine will be removed then and dismantled totally for inspection. I discovered that the bolts holding on the water pump timing chain cover were loose. I pray that was the problem, but hell. I got it almost all the way tore down now. Doing it all the way. Thanks for all the help guys... Dave "DMU" wrote in message ... Hi, My specific issue is this. New season - change the oil and filter.
