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.
replace a thread When you are working on your VW, you will encounter this problem at some point; a bolt of the crankcase cover doesn't really turn in the thread in the crankcase anymore. The more you try, the worse it gets. There is too little tension between the crankcase cover and crankcase, with oil leakage as a result.
removing the engine The air-cooled Volkswagen is an ingenious design, but not all work can be done with built-in engine, unfortunately. Sometimes it is also much more comfortable to work with the engine on the workbench hanging from an engine mount.
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.
Engine overhaul - video 12 the flywheel In this video, we'll explain how to disassemble and assemble the flywheel, and what tools you'll need to do so. To disassemble the flywheel, you will need to unscrew the gland nut. This nut is attached with a torque of 350 Nm, it will require some force to loosen.
Engine overhaul - video 16 part 2 valves removal In Part 1, we showed the basic techniques for disassembling the valves and valve springs. We did this on a fairly new cylinder head.
When you`re dealing with a used cylinder head, disassembly may be a little less smooth.
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.
engine types and codes The engine number indicates which type of engine is involved and with which engine capacity. The first letter(s) determine the capacity and type of engine and the following figures determine the year of manufacture. The engines up to and including July 31, 1965 had no letters for the engine number, which is why up to and including this year of manufacture only numbers are given.
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.
