Just had an engine rebuild after getting water in oil.
Thought the problem was corrected but it maybe traced to a cam issue and exhaust issue. Assuming I trace the water issue down (which I think a higher sweep riser will solve), do I need to have the engine disassembled or can I get by with Leak down, complression test and diesel fuel clean out?

Any feed back would be greatly appreciated as this will cost me lots of $$$ and lost time this season...

Thank you

first, how much water in oil? It takes alot of reversion to put much water in the oil, No you don't have to disassenmble the engine, you can do a leak down and a comp check if you want to, but that doesn't tell you where the water came from, could it have freeze damage? pressurize the engine with air, detatch the exaust hoses and put about 15lbs of air in it and see if it leaks, if it leaks down that is probably your water issue.
I've never used diesel before, but 4 qt's oil 2 qt's diesel for a short time, very short time, would probably work.

thank you for the feed back.
It is possible that the wrong CAM was used in a recent rebuild (rebuilt last week)!!
I am proposing to check the cam and change if nessisary, also leak down and compression. The pipes are original thogh the headers and intakes (brand new) headers 2 years in fresh water also tested good.

I will go to the high sweep risers as I have heard that is a better choice than the original as the 35 has a tendancy to have reversion issues with stock pipes....

your thoughts?

I don't think I have ever seen reversion bad enough to make milk shake. You will notice it at idle or when you snap a valve off If you have milkshake looking oil I would be looking at the exhaust for a leak first and move on. There are hundreds of post on this topic.
