VW Cylinder Head Machining

Post by arn3696 » Mon Mar 28, 2022 3:13 pm

Good afternoon all

It looks like we may need to purchase new cylinder heads for our 1834cc VW. Does anyone know, or can recommend, a reputable machinist to add the second spark plug holes and bore out the heads to the required 92mm? It appears, going through the paperwork, that a previous owner had some trouble finding a company willing to do it given it's purpose and in any event the previous company that carried out the work (Ramsay in Coventry) is apparently no longer trading.

Any help would be greatly appreciated

Someone in our owners WhatsApp group had some good work done at a very reasonable price by https://www.chaseengines.co.uk/. They are based at Newcastle-under-Lyme.

Try John Maher Racing. He did the clearance work on my crankcase for stroker pistons, albeit a few years ago. He is a VW guru and modifies engines for everything from buggies to dragsters. You can google him or take a look at his website, https://johnmaherracing.com/

Good luck, Peter

Let us know how you get on with whoever you find. Useful info to have.

As the VW is still used extensively at the grass roots end of the LAA Fleet, it strikes me that an online respository of related information (technical and suppliers) somewhere on the LAA website would be useful. Or does such a thing exist and I just haven't found it?

I still think that it would be useful to have a LAA course on the VW ( as has been done for the Rotax) to catch up with mechanical aspects and setting up of the electronic ignition system and in the interests of affordable aviation !

I think it would be a good idea to have courses on the small Continentals (O-200 etc) and for the 4 cylinder (O-235 / 290 / 320 / 360 / 390) and 6 cylinder (O-540) Lycomings.

There's a heck of a lot more of them flying than VWs.

As an example of the need for a Lycoming course I am stunned by how few Lycoming owners know they should clean out the finger oil strainer at the bottom of the sump at each oil change. It's only the main inlet to the oil pump. :shock:
It is pretty coarse but it does collect quite a build up of carbon lumps that come off the underside of the pistons.

Same with small Continentals. However removing the sump, requites removal of the carb and associated cables every 25hrs. Clearly not practical, so advised to flush sump after draining with fuel.
