common problems with d24/d24t??

[anders]

So I just picked up 2 D24T engines, wishing one will be a good runner to install in my 83 244. One of the engines had "oil in the water" as the seller stated. Now would this be from a faulty engine oil cooler? Or could it be worse and have a crack in the engine oil journal to a coolent passage?
The other engine has low compression. Do the intake valves get gummed up from carbon form the EGR valve causing low compression? Or do the cylinder walls wear out faster than other diesel engines? thanks..
