    Hi, Just bought an engine off e-bay. It has no Idenfictaion or engine code except a mystory A at the start of the code. Was told by the seller he was told it was a 1600 but when he removed the cylinders he found it was a 1300cc. He used the cylinders in another project. All I know about it is...

    Hey guys, I'm new to this website and fairly new to air-cooled classics in general! I would like some advice/ guidance on building a performance beetle engine. 1. Crankcase, I am after a pre-bored 94mm case, what would be a wiser purchase? Either a magnesium case or an aluminium super race...

    Hi, Today I am going to attempt to remove the years of built up muck and grime off the crankcase and rust of the other parts like heat exchangers and exhaust box. Has anyone got any tips on how to do this? I have some stuff called "gunk" and some general "Engine cleaner" which I am assuming is...

    So basically, after taking my engine out the other day I removed all the stuff on top and then came to inspect the exterior of the crankcase and I found these where the case mounts to the gearbox. I apologise for the terrible condition of the photos. My camera is crap. Basically there is a...

    Hi, I've got a spare case for sale, bought only as a backup in the event my case was not "rebuildable", but thankfully it is! It was bought from a guy on volkstorque called Phil1bug last year. I was told it's been checked and measured, no align bore needed and engine did not suffer any end...
  8. Aircooled Mechanical Tech
    Hello Hoping someone can give me some advice on my recent purchase, and tell me whether my decision was wise or not. I managed to get hold of a 1600 engine and gearbox for £200, the only problem being the hole in sump which I believe to be caused by corrosion (engine left sitting on the...

    I have an old engine which I've now stripped down and want to start to build a 1600 for my buggy. On opening and examining the main bearings - find that all of the saddles have a witness line where the bearing oil feed is - these have depth in the saddle. Also the bearing at the flywheel end...

    I've just picked up an engine case from GSF after i found the one i intended using was dead. It's got a couple of extra holes in it that i'm not sure what they're for, can anyone enlighten me? The one big hole on the right of the oil pump (bottom right corner) and the two threaded holes left and...
