Hello Marv;Sorry That I have misunderstood your problem.Somehow I had the impression that you had a problem with water getting into the crankcase oil.I guess I missed your original post but have not been able to locate it on my puter.If the problem is one of having bubbles in the radiator then disregard my last reply.I have had past experience on several German built diesels having porosity in cylinder sleeves.Upon visual examanination all sleeves appeared to be in perfect condition with all heads removed and pistons at bottom dead center.After replacing all heads and start up all water would be blown out of the cooling system within five minutes.As you mentioned in your post the possibility of testing each cylinder with use of compressed air thru the injector port is exactly the method I used to find the leaking sleeve.I was able to find the leaking sleeve with only 170 psi air.However if this leak is not evident with low pressure air it may only be a leak at near compression pressure.In that case I certainly would not test with any thing except High Pressure Nitrogen because of diesel effect upon any oil remaining in the cylinder.DO NOT USE HP OXYGEN.A leased cyl. of nitrogen is not expensive.In my case opon removal of the faulty sleeves they were picture perfect inside, however the outsides looked more like a sponge.This porosity allowed compression pressure to leak thru the grain of the cast iron sleeve and blow water out of the cooling systrm.
