does intake manifold galley sludge prevent proper oil passage? If so, what area should I inspect for issues and cleaning? I realize the best solution is a complete rebuild, but not possible at this time... thanks

Most sludge does not affect engine lubrication if it is left where it accumulated. The exception is when it accumulates on the oil pump pickup screen. Attempting to remove sludge without completely disassembling the engine can lead to dislodged sludge blocking oil passges. Tom

Tom() I am ignorant of how the intake galley receives oil? So the galley sludge does not impede lifter/valve stem lubrication?

Here is a diagram of the oil flow system in the 49-53 block. The 32-48 is very similar. The valves and lifters receive their oil from splash from the camshaft and the valley is just used a a return sump. Tom

Sludge build up within an engine is the result of poor maintenance, cheap non-detergent oil, no thermostat to bring the engine up to normal operating temps, poor ventilation, and short stop and go driving around town. The only solution to the problem is to rebuild the engine. When I was a teenager I worked in and around a lot of service stations and/or garages, it was very common to see vehicles with less than 50K on them that would hardly run. When we pulled the pan plug to do an oil change the oil was like molasses in January. Bill 36 5 win delx cpe
