Volkswagen soon discovered that replacing the push rod protection tubes was a labour-intensive business. In order to speed up this process, spring-adjustable tubes have been developed, allowing the tubes to be replaced without having to disassemble the engine. Remove the valve covers and rocker arm axles, pull the push rods out of the tubes and pull the tubes from between the crankcase and the cylinder head from below. Now mount the spring-adjustable tubes by sliding and releasing them between the housing and the cylinder head. You have again made a leak-free connection without removing the engine from the car.
The spring tubes mentioned here are an advanced Volkswagen model. For example, the tubes for type 1 and type 3 engines are fitted as standard with a longer section on the sump side (windage) which ensures that the oil remains in the sump during fast cornering and is not sucked in through the tubes. Models for CT/CZ and WBX engines do not have this additional feature, but are improved over the original. Unique, the sealing between the two parts is ensured by three successive sealing rings, most tubes have only two and even one original VW sealing ring. An additional advantage of these tubes is that they can also be used for Type 1 and Type 3 engines with high valve lift. The side of the cylinder head has a larger diameter than the side of the crankcase, sufficient to give more space for the push rods. Both types are delivered in 8 pieces, including seals. They are made of aluminum, which not only improves the view from below but also directly addresses the problem of rust. Whether you need to replace the push rod tubes with an integrated motor to save time, a solution for performance engines or an improvement over the original, with these spring-adjustable tubes you are making a very good choice.
Seals are supplied (standard seals), but are for single use only. If you need the gaskets separately or if you want to mount silicone gaskets for a better seal, look under the "options" tab.
If you are looking for the original tubes, look under the "related parts" tab.
