Priming Ford Modular Engine Oil Pumps
If you are working on Ford Modular Engines, watch this tech tip video featuring our tech director Cale Risinger talking about priming the oil pump.
Premature wear in late model oil pumps due to dry starting is one of the primary issues we see at Melling. One of the big differences in late model engines relative to older engines is the location of the oil pump. In most older engines the oil pump resides in the oil pan and is partially submerged in the engine oil. Oil pumps in late model engines no longer reside in the oil pan but are mounted over the crankshaft. The change in location increases the length of the oil pickup tubes which increases the time to fully pressurize the engine. As a result the priming of the oil pump and also the engine are critical steps that must be followed before initial start-up.
GM LS Lifter Issue, Melling JB-7011 Tech Tips
If you are working on a GM LS Engine, watch this tech tip video featuring our tech director Cale Risinger talking about Melling JB-7011 lifters.
The Melling tech department is finding that customers are experiencing repeat AFM lifter failures. Please carefully review this video to assist when rebuilding an LS engine with a failed AFM lifter. They can be identified by the compressed state of the exterior spring. This indicates an issue with the VLOM manifold assembly. This includes the VLOM filter and the solenoids. Proper attention will assure that a repeat occurrence will not happen. We are finding that customers are experiencing repeat AFM lifter failures when the VLOM system is not properly serviced when the lifters are replaced.
