1970 silverline comoro water in oil

[weightset]

so today I hooked the muffs up turned the water on and started the boat ran awesome, when I checked the oil it was white/milky color. the boat ran perfectly fine however no smoke needed a little throttle to keep it idling. this is the first time I have had the boat started btw was wondering what could the suspect of this be. It has a mercruiser 2.5 in it as well

How much water in the oil are we talking about here? Is the boat new to you?

Re: 1970 silverline comoro water in oil

yes boat is new to me and it only ran for about 10 minutes and the oil is white lol the boat has set since summer of 11 I don't know much more about the story before I acquired it

Is the oil level way over full? Being white, I would bet it is. Probably a cracked block from improper winterization.

Re: 1970 silverline comoro water in oil

yea its quite overfull now, so would you throw out a head gasket problem or no

Re: 1970 silverline comoro water in oil

what are all of my options of what it could be I should say, and what would be ur first means of attacking this problem

Pull the side covers off, you should be able to see the cracks behind the push rods.

No, it's not a head gasket. That's what everybody hopes for, just never is.

Where are the side covers located shouldn't I have to pull the valve cover off then the head or is there a different way its only the 153 ci 4 cyl

Re: 1970 silverline comoro water in oil

I should have said side cover, there is only one. Starboard side of the block, just below the head.

There is no manifold on the starboard side.

Re: 1970 silverline comoro water in oil

So u mean the side with the spark plugs. I still don't know my boat terminology

Re: 1970 silverline comoro water in oil

So say I remove that cover and I have cracks what are my options and if I don't see cracks what are my options
