water in oil!
 

Sucked out last years oil in my port motor and it looks like chocolate milk:mad:

I just had the valve seats reground last June, So I doubt that my problem would lie in the head gaskets, or the actuall heads themselves . Riser gaskets were also replaced at this time...Does anyone know of a slick way to cap off the exhaust end of a Riser in order to pressure test the riser and manifold??

The boat is stored in a climate controlled shop year round so frozzen and cracked parts are out of the question.

Anyone have any other possible suggestions as to where to start looking for my problem?

there needs to be a Forum just for this Subject .....I am going thru H2O/Oil now ....mine got hot though ...and I am pretty green at this but have learned it has to be Risers,Heads,Exhaust Manifolds, Cracked Block ..or maybe inhaled thru Exhaust .... I was told no ez way to test riser ... maybe a plumbing rubber cap/boot ...I assume your going to test them together ?

You state you had valve seats done But did you put new springs on? Check for brocken exhaust springs if not replaced

That sucks, intake to head is a frequent problem area. I use ultrablack around the water ports when I put them on. Were those stock manifolds?

It could also be gas in your oil. You can tell by smell.

I just happened to do thids today on a friend 330. Went to the hard ware store and bought end caps for the hose from to the exh mamnifols, Plugged uo the fresh water wasout. Used an old radiator neck and clamped the 2 tightly.Prior I filed the block with water and pumped it about 15 lbs. Marked the dipstic and will check on this in the am.
Als am doing a leak down test aas well with a compression test.

My friend bought a really neet tool that feeds ihrugh the sparkplug hole annd this may help me know something i A litle round flexable shaft with a light on it
