Art, I didn't mean for the comment about the sleeve seals to be taken as a possible cause for smoking, rather just a caution to those who consider buying a 50 series CUT that has been sitting a while. What I find is that the lower o-ring (which is of a composition as to be oil resistant) dries out and cracks, letting oil get to the upper ring (which isn't OIL resistant, but COOLANT resistant) thus softening the upper o-ring (similar to a Gummi Worm left out in the weather too long). When this happens, coolant seepage into the crankcase is the result, often with some rather expensive damage occuring. Been there, seen that. Several times.

Actualy, it's the fitting itself (with screen) as well as the lift valve that must be changed. What happens is this: The screen catches some debris, which causes a partial restriction at the screen. The resulting pressure differential on the upstream and downstream sides of the fitting literaly blows the screen out of the fitting and into the lift valve. Then the operation of the lift valve causes the stainless steel screen to score the lift valve spool.
