So i bought a new set of pistons and cylinders for my motor and they arent even close to what was in the motor. I was told this engine was a 1600cc from the guy i got it from. So i just assumed everything was stock when i bought the new parts. My fault obviously. What it has in it are 92mm pistons and over sized thick wall cylinders to match. The case appears to have been bored out to accept the larger cylinders. The cylinders OD measures 95.5mm at the base where it fits into the case and 98mm where it fits in the heads. I cant find any cylinders to buy that match those dimensions. Is this an odd ball outdated size or am i just not looking in the right places? Can i buy pistons that are just a hair larger and have my cylinders bored over to match? I manage a CNC shop with about 25 machines at my disposal so i can do my own machining. Just not sure where to find the odd ball parts.

When I went thought Auto Repair school, They had me work on a bad VW Bus engine. Bad piston so order a new one. Back in the bus & started it. BANG, BANG, BANG!!!!!!!! Out it came & apart. Some one had decked the pistons .20. Never worked on another VW or anything they ever made in my 35 years as a grease monkey. Also to many tools & jigs for them. |

I don't think I have ever seen an actual completely stock VW engine in my life (which hasn't been that long, but still) on the bright side, There are 1,000,000,000 after market parts you can get for it , so if you spend hour after hour painstakingly figuring out what you have, you can usually find exactly what you need. as with most engine questions, try searching on thesamba. If no one has some, there is probably a hotlink to somewhere useful to that circumstance. |

The reasons above would, I think, merit positives not negatives. Because the aircooled engine is so interchangeable, accessible, and basic it allows the massive amounts of "personalization". I think the problem was not the engine but that the person misrepresented his engine. Disagree with the "too many tools" too - actually they are very few. "the people's car" was meant to be worked on by anyone with very limited resources. "no stock ones left"? Uh, this is an old engine, made many years ago - a similar question would be how come I don't see many stock 440 engines. Just putting up for the 'ol aircooled!  |

I agree with guamie, one of the main reasons I have two ACVW vehicles is that I know I will always be able to find parts to repair it, people to work on it, etc. I want pre-1975 cars to avoid dealing with smogging issues and to be able to fix it myself (ignition switch went bad in my late model vehicle with a computer chip key just as we were leaving on a vacation trip and was impossible to bypass-delaying trip, and cost about $500 to repair). It just reminded me why I like ACVW.
Warmest....

sounds to me like 92mm "machining required" pistons vs. the thin-walled "slip-in" that most lazy guys go for.
I would think there has to be a vw shop somewhere in town where you live where you can get parts. I had one cylinder rust after sitting for 20 yrs., went to a local vw "speed" shop, $20, and I had a new piston & cylinder.

I'd just like to point out that while I see how my last post read as negative, I meant it as a positive! lol. I hadn't seen one without at least one mod, even if it was just oil pump, oil cooler, or dizzy. - On a side note I have now made that last post a lie, I picked up some cheap winter rims on the 29th, the fellow selling them (for $20) had a beautiful 67Ghia that he enters in the concours d'elegance every year. bone stock, lol. gitrdun- Having that CNC shop at your disposal is going to come in handy when playing with these engines. you can make a lot of really cool easy fix parts that others would have to buy. |
