The right fasteners, installed the right way, can enhance the quality of any build.
Properly replacing Subaru EJ25 head gaskets takes patience and quality parts.
Choate Engineering Performance created a hybrid 6.0L/6.4L with a Procharger and nitrous. Find out what went into the build!
Modern engines need to know the position of the crankshaft and camshafts. Why? The timing of the valves, fuel injectors and ignition coils are continually optimized for the most efficient combustion event depending on the load and speed of the engine. But the other reason for knowing the position of the crankshaft is for misfire detection.
Sometimes the least expensive parts are the most time-consuming to replace. This is the case with crankshaft oil seals.
Andrew Markel discusses a recall from Hyundai on its Theta engine, and how technicians can determine whether the engine has been inspected or replaced. Sponsored by Auto Value and Bumper to Bumper.
The Hyundai Theta engine appeared in 2006 Sonata models and is going strong to this day in naturally aspirated and turbocharged forms in various Hyundai and Kia applications. The one area of the engine that has been the source of more TSBs and tech tips has been the bottom end of the engine and lubrication system.
Performance enthusiasts may have some experience with “wet belt” timing systems as an upgrade for the small-block Chevy, but these “new” belt-in-oil systems are OEM designs, used for oil pump drives as well as for camshaft timing drives.
Head lift is not the whole head that is lifting from the block, but is a distortion in specific areas of the head and block interface where the head gasket is installed. This distortion can damage the head gaskets and head bolts.
Andrew Markel discusses common symptoms pointing to a failed or leaking head gasket, and the tools needed to diagnose the issues. Sponsored by Bar’s Leaks.
You may have noticed that some Toyota and Honda four-cylinder vehicles require SAE viscosity 0W16 oil. The oils really stand out on a shelf because the last number is strange because it does not end in a five or zero. You may have noticed it in the catalog pages or shelves of your oil supplier. 0W16 oil has been around for almost two decades in Japan. It is an oil that is designed to increase engine efficiency and reduce engine warmup time.
