Re: Milky oil
 

can you say head gaskets ??????

Re: Milky oil
 

I dont know what area you are in but find someone that knows what they are doing to check them out, but all in all id be worried about a lot of things at this point if you want give me a call in the next 30 min or tomorrow and I will give you some tips to look for ......

Re: Milky oil
 

What I don't understand is that they installed the motor in the boat anyway after knowing this!
I spoke to them today and they said they ran the motors in the boat. I forgot to ask about the oil situation.

Re: Milky oil
 

I would guess head gaskets or cracked head. If it wasn't a fresh rebuild I would say to check your exhaust risers, especially if it had been sitting for a while. What head gaskets did they use? Felpro marine or Cometic? If they used some local part store stuff I would be concerned, I would also be concerned about the rest of the rebuild.

Before jumping to conclusions are there oil coolers on this application?? Yes it could still be a HD gskt, but I have seen coolers do some funny stuff too.. Jamie / Lakeside

That's a good idea, take it off and pressure test it.

Thanks BADKACHINA... :) :) Jamie

Re: Milky oil
 

what about intake gaskets?

Re: Milky oil
 

it could actually be one of many things from a pin hole in the intake under the stat to gaskets ect, as white scarab said I also dont under stand why they would drop it in with these problems unless they just want the $$$$

Re: Milky oil
 

True.. :) thats annother good idea. Could get water in if one pops or the intake corroded or cracked internally..
I mentioned what I did earlier because depending on where the boat is kept it could have corroded, or if the water from the oil cooler wasnt drained It would be suspect to me incase it froze for one ... Jamie

Joe, you must have been posting at the same time... That is a good question. Why install an engine that has suspect "issues" ??? It seems like a waste of timem & money to me...

To the person with these woes. Is the shop doing the work reputable? Or refered to you by someone you trust?? Or just some place you you looked up & tried on a whim... I am not trying to be rude, I am just curious. As I would not install an engine with something like that unless I found & fixed what I thought to be the problem first.. Keep us posted.. :)

Re: Milky oil
 

Just wondering why you would think oil coolers?
He said the problem showed when the engine was run out of the boat. Were the oil coolers even hooked up at that time?

Re: Milky oil
 

the oil coolers IMO should have been on to run it. The coolers can deriorate or rupture inside letting oil in water or vice versa.. Im not saying it is his problem, but it could be. I usually have to replace a few a year because of deterioration or someone winterizing themself & forgetting to drain the water out of them eventhough they drained the manifolds & block. I only said it as a thought so if it was a cooler that the person didnt go thru unecessary head work & expense.. :) Jamie / Lakeside

Donzi:
You make a good point. I was just wondering about running the engine out of the boat with the oil cooler. I wonder how many people actually do that.
That's why I like coming here, I learn something new every day! :)
