How does the lock barrel work, and what is the difference between the left- and right-hand mechanisms. Can you use a left-hand handle on a right-hand door? Does it even matter?

While refurbishing my 1989 VW Transporter T25, I discovered that the spring clips which hold the halves of the airbox together were so badly corroded that they were unusable. Crumbling to dust would be a good description of them. I tried various sources but could find no replacement which claimed to be for this specific vehicle

After spending many years refurbishing my 1989 VW T25 Camper which is fitted with a Waterboxer DG Series engine, I finally had to give up on the carburettor.
The original Pierburg 2E3 was suffering from issues, but a service kit and readjustment didn’t fix my problems, which were that it didn’t start from cold, ran lumpy, and until it warmed up it would stall when opening the throttle.

My VW Transporter T25 DG series engine had started developing white and green residue, especially underneath and around the black rubber gaskets either side of the cylinder heads. At some point it also began using water.

To fix it you’ll have to take the cylinder heads off and do some work on them. With a bit of effort, and if you’re careful, you can do this with the engine in situ.
