Engine diagnostics - video 03 pushrods In video fourteen of our series on engine overhaul, we disassembled and reassembled the rocker arms and pushrods. In this video, we will inspect the pushrods. The result of this diagnosis, will tell us if we can reinsert the pushrods, or if we need to replace them.
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.
Engine overhaul - video 04 removing the distributor drive shaft We want to give extra attention in this video to the position of the distributor drive shaft of the VW Type 1 engines, . If the drive shaft of the distributor is not correctly mounted during the engine overhaul, problems can arise later with the adjustment of the ignition timing. Disassembling the drive shaft is then the only solution.
fuel circuit - concept The combustion engine of our air-cooled Volkswagen uses a mixture of petrol and air. It is extremely important that both the amount of air and the purity of the air are regulated, this also applies to the petrol. Unfortunately, the petrol circuit is not very well known to enthusiasts and it is not always well maintained.
Engine adjustment - video 01 valve clearance The valve clearance is the first thing to check when adjusting an engine. If the valve clearance is not adjusted properly, then adjusting for example, the ignition, or the carburetor, will do little good. In this video we will show you how to adjust the valve clearance.
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.
air filter preheating It seems to be a natural part of your air-cooled engine, but the air filter plays a crucial role, it's like breathing in a human being. The carburettor is tasked with mixing petrol with air to deliver a flammable mixture. Petrol alone is not a good fuel. That requires oxygen and not just a little bit of it.
Engine diagnostics - video 04 part 2 valves and valve springs In the second and third parts of this video, we will measure valve spring pressure. We begin in part 2 by measuring the valve spring pressure at open valve. Also known as the valve spring pressure at maximum valve lift. In part 3, we will measure the valve spring pressure at installed length.
HPMX carburetors The most famous double carburettors are the Weber IDF and the Dellorto DRLA. Since a few years there is a new player on the market, namely the HPMX carburettor. This is marketed by EMPI and is also sold as a complete set, including manifolds, air filters, linkage and mounting material.
mixture preheating The engine is stopped as a result of poor combustion. This bad combustion is often caused by a, at that moment, wrong composition of the fuel in the cylinders. Because of this bad combustion, the engine does not deliver the desired power and you can feel this in the form of stuttering of the engine.
