Engine diagnostics - video 01 crankshaft end play In the first video of this new series, we will look at how to measure the crankshaft end play. Measuring the crankshaft end play, will help you estimate if your engine needs a total overhaul. If the result of the measurement is greater than or equal to 0.15 millimeters, then the crankshaft clearance is too large, and a total engine overhaul is recommended.
air filter thermostat The preheating of the fresh air supplied via the air filter to the carburettor is a part of our VW engine that gets too little attention. This system will ensure that in all weather conditions the carburettor is supplied with air at the right temperature. With these younger air filter models you don't have to adjust anything in contrast to the older models.
Engine adjustment - video 02 adjusting the rocker arms In the first video of this series, we adjusted the valve clearance.
