What’s the story on piston cooling tubes for Navistar diesel engines? The AERA Technical Department says that the piston cooling tube design on Navistar DT 466 and 570 diesel engines has been revised, and this information should be considered anytime the tubes are removed for service on engines with a serial number higher than 2,000,000.
PERA’s Core Corner: Getting A Leg Up On The Ford Duratec Cover-Up
No matter how much the engine remanufacturing and building industry changes, one thing will always remain the same. Identifying what type of engine on which you’re working will be an important – and challenging – part of the process. Today the front cover has become such an integral part of application identification that it has
Rebuilding the Ford 3.0L
This engine came out of the Cleveland Engine Plant #2 (CEP2), originally opened in 1955 to manufacture the 361 cid truck engine. By 1985, this facility was down to 400 employees and on the verge of closing. Then in 1988, plant renovation was begun (with the 3.0L Duratec engine family on the drawing board) at
