Useful information from Paruzzi magazine and from our YouTube channel :
mesuring the compression How can you determine very objectively how much wear the engine has? An indication of the wear level can be obtained by performing a compression measurement, the engine compression determines the power of your VW. Anyone can perform a compression measurement on an air-cooled or water-cooled VW.
crankshaft seal replacement If you find that the crankshaft clearance is outside the factory specifications, replacing the crankshaft seal will not be a solution for the oil leak you have identified. If the crankshaft clearance is less than 0.30 mm, it makes sense to replace the oil seal, otherwise a total engine overhaul is the only worthwhile option.
Engine overhaul - video 09 the fuel pump We will disassemble and reassemble the mechanical fuel pump from a VW Type 1 engine with carburetor in this video. The electric fuel pump is discussed in another video. The fuel pump pushrod and the fuel pump flange get extra attention in this video.
oil seals All rotating parts fitted with bearings lubricated by oil or grease, such as crankshafts, transmission shafts, drive shafts, steering rods, etc., must be sealed. In our classic VW's we find two types of oil seals, namely the static and the dynamic (lip seal) oil seals.
Engine adjustment - video 02 adjusting the rocker arms In the first video of this series, we adjusted the valve clearance. In addition to the valve clearance, the position of the rocker arm relative to the valve stem, is also a very important setting. If a rocker arm is not positioned correctly, it can be adjusted, which is called shimming.
oil pressure gauge After an engine rebuild, when you start the engine for the first time, and when you start driving, you need to keep a close eye on a number of engine parameters. The most important are oil pressure, engine oil temperature and cylinder head temperature.
cylinder head specifications One of the most heavily loaded parts in the air-cooled VW engine is undoubtedly the cylinder head. Especially the valves, valve guides and valve seats have to endure a lot because of the high temperatures, the temperature differences and the mechanical load in an air-cooled engine.
Engine overhaul - video 07 TDC compression in practice In video six, we explained the operation of the four-stroke internal combustion engine through animations. In this video we will look at how to determine the top dead centre of cylinder 1 in practice. We will also learn how to find the compression stroke of cylinder 1, different techniques will be shown.
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 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.
