So I just had an engine survey done on a 88' E-38 with the Universal 5432 Diesel engine. It has no hour meter. Planning on doing a full marine survey next week but had the engine survey done first to see if there were any red flags. I'm not sure if this is common for a boat this age but I'm wondering what others think, this is one a several things he found, but I think it's the most important.
The Surveyor said the engine appears to have a high crank case pressure (blow by). This is why there is oil leaking out of the dip stick. From what I can tell the dipstick has a loose fit as the rubber seal is quite worn, there's no question the dipstick needs to be replaced just not sure how serious this is or if it'll be a recurring problem with the compression. Anyway he continued to say that high crank case pressure is usually an indication of moderate to high internal wear. And that without the knowledge of engine hours it's a good indication that this engine has seen a lot of use.
Also said transmission oil appeared dirty during sea trial and it's a good indication of clutch plate wear within the transmission. Recommend changing the transmission oil and monitoring the oil for ongoing contamination from clutch plate wear.
Waiting for results from the oil sample should have that soon too.
Anyway for a 28 year old engine is high compression fairly common? And how often in a case like this does an engine need a rebuild or re-power? 3-5yrs? I'm wondering how much time the old girl has left, curious if others have had similar diagnosis on theirs. Or live with it and baby it.
