Review on Hydraulic Compatible Silverado Cadillac 12499225 by David Elam

By the way, this is not my first engine overhaul. 3 out of 8 AFM lifters stuck the valve during cranking for oil pressure or possibly before installation. The other 3 had the roller shaft/bearing sticking out of the lifter bore about 0.001" which made a horrible noise at launch. The engine ran a total of 40 seconds and it was not possible to manually remove the 3 AFM lifters during disassembly. The resulting line scratches left in the jack bore by removing a small slide hammer require block removal, complete disassembly and machining to install steel bushings or purchase a new block. called.
