I have been hounding everyone on here for weeks with my milky oil :( i keep digging more and more. Well every time i pull off the riser the third cyl back directly under the riser has water in it. This is obviously my problem with the milky oil. SO i pulled the manifold and seems to be ok? could the head be cracked? could thqat cause water to get into the cyl? Or head gasket? Whats the next step i should take? thanks a lot for all the help everyone has givin me.

Yes, I had the same problem last year.My manifolds were only a year old and had water in the exhaust port with some pitting.Replaced the head gasket and still had milky oil.Ended up being a cracked head.If you plan on changing the head gasket I would get the head checked out while it is off.

how about cracked riser, riser gasket, cracked manifold look into the exhaust port of that cylinder and look for rust line on a crack

i assume you drain the manifold before pulling the riser?

just throwin ideas out there :confused:

water in oil

you could pressure test the exhaust system
you could pressure test the block
you could do a leak down test on each cylinder
you could take your boat to the shop have them look at it , sometimes this is the best way
Good luck

take the exhaust off an plug up the water inlets outlets hook up a gauge to the air hose with a valve so you can close it ff and fill with say 30lbs an see if the presure drops ,use soapy water to look for leaks ,I hope this helps,if it is your exhaust, thats any easy fix.
