Engine buider completed two rebuids. After running the two motors out of the boat the oil in one was milky.
What should be done on my part along with his.
Also, the motors were supposed to be dynoed and now there not. What are my concerns, etc.
Please help!!!!

can you say head gaskets ??????


and if these arnt even in the boat yet Id be worried about every thing else also

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 ......

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.

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

what about intake gaskets?

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 $$$$
