Measurement of Piston Protrusion
From the Motorservice Group – Following reconditioning of the engine block or the crank mechanism the piston protrusion in diesel engines must be checked.
How to Install Fel-Pro Gaskets
Proper installation of Fel-Pro gaskets is the key to long service life. Join Master Technician John Gurnig of the Fel-Pro Field Test Garage as he demonstrates how to install a variety of gaskets from the Fel-Pro lineup. From Fel-Pro PermaTorque® MLS head gaskets to PermaDryPlus® oil pan gaskets, John runs through the gaskets that are installed dry with no sealant.
While in the past it was not uncommon to coat a gasket with sealer or adhesive before installing it; today, clean and dry installation is the preferred method for most Fel-Pro gaskets. John also shows some gaskets that require a small amount of sealant for mating or filling gaps. Count on Fel-Pro to help you get your vehicle repair done right.
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.
