Is this the Death of my Engine

Re: Is this the Death of my Engine

This is what I hate about this site. Everyone is quick to respond when there is a simple problem however when I need help where is everyone. How did water get into my oil if the pressure test was ok? Can I test the oil system?HELP

Ayuh,... This forum moves Fast,... I never go beyond page 1...

If the motor's cooling system was drained Dry, 'n you Attempted the pressure test,...
So far you've done Nothing....
The pressure test was NOT done...
It has to be SEALED to check for loss of pressure...

No,...
There's No test for the oil system...
That's not where the Problem is....

Squab, take a deep breath. They are trying to help and rule out some more of the common issues by methodically diagnosing the problem. Bond-o,s point is that to be absolutely certain there was no leak down in the system elsewhere you need to be sure that that the thermostat housing is not leaking as well. The leak could be small and only detectable after it sits for a while. So go back and retry the test and see what you have and they can continue to go from there.

Re: Is this the Death of my Engine

You need to get your housing air tight to do your pressure test. You haven't done your test until you get that done first.

Why didn't you just do it with the thermostat housing on there? Did I miss something where your thermostat housing was removed?

Re: Is this the Death of my Engine

housing was removed because the gaskets were bad. I also pulled the exhause manifolds and fould that the gaskets there seemed to be all melted. It seems like the passages in the thermostat housing are really rusted and lacking full water flow. Could this be a problem allowing water in the oil?

Nope, Not really....
It's sounding more, 'n more like this motor has All kinds a Problems...

Hey Bondo,
It is a classic. 1989 which I inherited 15 years ago and have been nursing her all along. There is not one thing that I havent touched. I appreciate the sarcasm, however I dont need to hear how my boat is a clunker, I NEED to hear how to fix this weeks problem. If you have nothing nice to say>>>>>

Sorry,... I'll leave ya alone....

Re: Is this the Death of my Engine

Bondo,
I am getting lots of good advise I was jsut asking if the restriction in the thermostat housing could have made the exhaust too hot which woiuld melt the gaskets and allow water to get into the exhaust ports. Would this make my oil with water

Good post.

Re: Is this the Death of my Engine

Just an outsider looking in. I would think that if you bolted everything back up with new gaskets and then repressure tested the cooling system you then would be able to verify were the leak is. Or if when you changed out the one manifold and it had a bad gasket or sealing surface/improper installation ECT from last year. You would now have a place to start looking. Most likely you do not have a bad head gasket., if so then something had caused this like frozen water. The folks on here are very knowledgeable and want to help, but you have to give detailed info to what you have done and what is happening. Good Luck

I have to agree with you.

If there's a leak, then identify it, fix it before you assume it was the only leak.......

You may have an internal leak that that you cannot hear when the T-stat leak is leaking.....

You need to pump the engine up to 15 psi or so and have it hold (with the pressure source disconnected or shut off) before you can reliably say there's no other leaks...............


Understand, at this time of year, CRACKED BLOCKS ARE THE MOST COMMON SOURCE OF oil in water problems.......

It's not the only source but You must rule it out before looking elsewhere.....

Re: Is this the Death of my Engine

You say you winterized your boat, but you didn't change the oil? You also say that it could of happened last summer, how often do you even check our oil? Also if water was getting in your oil pan while you were running, you most certainly would of known. No one wants to hear that their block is cracked, but you can call a squirrel a rabbit all you want its still a squirrel. You could always have your block scoped, they know right where to look for the cracks. If you drained your block last year and didnt use air or a piece of wire to clean out all the drain holes, you probably didnt get all the water out.

Re: Is this the Death of my Engine

Squab, I think you need to fully answer all points brought up in the previous thread. This is where I would start it has been asked a few times but never answered completely. Dumping some antifreeze down the hoses will not winterize a block, as you may soon discover. Why were you going to start it without manifolds and a t stat anyway?

 

[Squab]

Re: Is this the Death of my Engine

Guys, Thanks for all the good posts. I did winterize it by pouring antifreeze in the hoses. I am not sure if I did infact drain the block. Going to give it a true pressure test this weekend (weather permitting). I was going to start it and had manifolds and tstat on, just removed after problems arose.
