Coolant in the oil....crap!

[Bodofish]

455 in a boat is pretty common thing. I'll bet you get a crate marine engine out of kent. There's a couple engine builders there that do auto and marine.

Jackson,

Its because they are deparate for your business.

Should put us on your list next time you need help. We do honest work and you wont get skinned alive doing business with us.

So here is some fun info..... After 4 rivers quoted me near 8K to fix my blown up, craked block, "worst case scenario" engine, I decided to pick it up and take it to Skagen Marine instead. They came very highly recomended from a friend, so I thought I would have them look at it. I just got a call from them. The block is not cracked, nor are the heads. There is a hole in the manifold. No big deal to fix, however, after 3 rivers left the coolant in the pan and the cylinders for 2 weeks, the bearings and rings are now gone, so I have to pull the motor and rebuild it anyway. Makes you want to kill people.

A hole in either manifold is not going to cause water intrusion into the oil. Somewhere there is/was a leak between the two systems due to gasket failure or warped head(s) if the block wasn't cracked. Either way once coolant got into the oil, pulling the motor would be prudent to ensure that it gets fully inspected and properly cleaned out. Someone should have been able to show you where the failure between the two systems occurred, without positive proof it is only a guess as to what caused the problem. If the block isn't cracked you should be able to pick up a remanufactured engine with core exchange for under $2K.

Like G-Man said, a hole in the manifold is not going to cause your anti-freeze in oil situation. Be careful with who fixes it. Make them explain why the hole in the manifold caused your oil to be contaminated with antifreeze.

Couldnt it get in through the exhaust ports and go into the cylinders and past the rings...?

[flinginpooh]

Ive not rebuilt a motor before but kinda understand most parts of the motor. I was pretty sure the intake manifold only has fuel and air in it. Fuel and air are forced into the carb then passes it to the manifold that is like a splitter if ya will and then into the intake valves fires up from the spark on the upswing of the piston and out the exhaust valves. To the best of my knowledge there isnt any water flowing in the intake manifold. If there is then yeah there definately can be water in your oil because of that.

If its getting in from an exhaust valve and Through the rings then its not from your intake manifold. Even if it was your exhaust manifold cracked there is no water in your exhaust manifold.

I dont claim to be the greatest mechanic either, but in a jet boat, doesent raw water, coolant and the exhaust system all run through the heat exchanger system, which hooks up the the exhaust manifold.....somehow??

[scott080379]

if nothing is cracked then it would be a head gasket......if the heads haven't been pulled yet they still need to checked for cracks and machined. like already said you should still have the motor gone through, it needs to be properly cleaned and all bearings and crap needs to be checked.

1] depends on the engine design as to whether or not there is water in the intake manifold. I have no idea on THAT engine

for starters;

2] do a CYLINDER PRESSURE TEST, and LEAK DOWN TEST for a bad head gasket, cracked cylinder wall, etc.

4] do a coolant system pressure test to see where the water is going - could reveal a bad gasket, or cracked block/head. And thus the leak down test - will show which cylinder/cylinder wall is cracked. If there is no water going thru THAT design of INTAKE manifold, take it off and check the lifter galley very closely, etc. while doing the coolant system pressure test.

5] take off the heads and check it all out including magnafluxing the heads and block.

[G-Man]

Short of having a hole in the piston, there is really no way that amount of water is getting in through any valve and past the rings and into the oilpan. Coolant is circulated through the block and heads, the manifolds get neither oil or coolant. Perhaps one of the heads had the hole blown in it and there was some mis-communication involved.

Ah here we go again. So this is yet another case of three dogs and a mule ruining marine equipment that has been left in their care. My fishing buddy took his boat in for a tune up and before they were done he had to replace the interior and repower the boat. Mind you he did buy a Suz OB and it's sweet! But........ Get your boat away from them as fast as you can. Skaggen is the spot for Jet Boats!!!! Want that pump blue printed? Need some more ponies? It's all taken care of there. They live and breath jet boats and V drive. They will know exactly what to do with a 455!!!

As for water getting from either intake or exhaust into the case, not a problem especially if it ever hydroliced even just slightly. Check the rods carefully....... I'm sure they will.

Exactly, many, many intake manifolds are of the "wet" design. Like AMX, I'm not familiar with the 455 though, but coolant in the oil, antifreeze specifically, will indeed destroy your bearings. As others have recommended, have the engine thoroughly check top to bottom. Nothing I hate more than having to do something more than once, and if the engine has to come out, may as well bite the bullet and do it right. Good luck!

Oh crud, German Spam!!!!!

[Jaksonbrown]

Boat is fixed!!!!! In the end, it was a cracked head that was the culprit. Now I have a newly rebuilt 455. New pistons, rods, crank... the whole shabang. The old motor would only turn about 4200 rpms... Tony says that it does 6500rpms now. This thing should scream on the water now. I cant wait to get it in the water!

See you all out there this weekend!
