Engine diagnostics - video 04 part 1 valves and valve springs In video 16 of the engine overhaul series, we disassembled the valves and valve springs.
Not all of the cylinder heads we showed were in good condition, this does not mean that all parts need to be replaced. After a thorough diagnosis, it will show if the valves and valve springs are still reusable. This video discusses valve and valve spring diagnosis. It consists of four parts.
Engine overhaul - video 16 part 1 valves removal In this first part of video 16, we disassemble cylinder head valves and valve springs. In the first part, we start by demonstrating the tools and techniques used, and disassemble the valves of a relatively new cylinder head.
Engine overhaul - video 14 rockers and pushrods In this video we will show how to disassemble and reassemble the rocker arms and pushrods. We will discuss the diagnosis of the rockers and pushrods in our other video series, which deals with engine diagnosis. How to adjust the rockers, an action also known as shimming, can be seen in our video series on engine adjustment.
Engine overhaul - video 06 find the TDC compression stroke We will explain in this video how to determine the top dead center, as well as which of the two top dead center moments is this one from the compression stroke. This is important in order to properly position the distributor drive shaft. Properly understanding how a four-stroke engine works is essential when you begin an engine overhaul.
Engine overhaul - video 03 the workshop We show in this video what the possibilities are to work on your VW engine. If you plan to overhaul several engines, then buying a professional engine stand is recommended. If you only want to overhaul the engine of your own classic Volkswagen, then buying special tools is not cost effective. We will show all options.
oil consumption Oil leaks are easy to rectify, sometimes even without having to remove the motor. We have saved the more difficult cases for this article, so we did not call this "oil leaks part 2" but "oil consumption". The distinction between the two is sometimes difficult to make, hopefully the information that follows will bring clarity.
the valve clearance explained The valves of the VW boxer engine ensure that the petrol air mixture can be fed into the cylinders (through the inlet valves), and that after compression this mixture can be discharged through the exhaust (exhaust valves). An accurate adjustment of the valves is of utmost importance for the proper functioning of your engine.
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.
Engine diagnostics - video 02 rockers and rocker arm In video fourteen of our engine overhaul video series, we disassembled and reassembled the rocker arms and rocker shaft. We will diagnose the rocker arms and rocker shaft in this video. Additional attention will be paid to the adjusting screws and adjusting nuts.
