The engines of yesteryear were pretty simple, with tappets clackity-clacking away on cam lobes, opening valves, and making a ruckus while doing it. Mechanical lifters were adequate for valve operation ...

GM EcoTec3 V8 lifter failures on L84 and L87 engines stem from low oil pressure during Dynamic Fuel Management cycles. This ...

Why ticking happens: Ticking occurs when a lifter cannot maintain zero lash due to wear, sludge, or poor oil flow, creating a rhythmic tap that follows engine RPM. High‑risk engines: Engines like ...

We may receive a commission on purchases made from links. There are many V6 and V8 engines that use camshafts located within the engine block and pushrods to activate overhead valves. In those engines ...

Engine room and motor box access ranges from easy to inconvenient to knuckle-busting tough. It’s bad enough trying to reach the oil pan or bilge pumps in most boats that you shouldn’t have to struggle ...

According to my ongoing tracking of manufacturing defects, proprietary field data reveals a hidden epidemic of low-line ...
