I guess the only place to start with this thread is the beginning... I have a friend who purchased a 914 to toy with, and he talked me into getting one also (didn't take much talking to peak my interest (IMG:style_emoticons/default/ohmy.gif)). Well I ended up with four 914's in a package deal ('70, '72, '72, '74). Only one of them actually runs ('74 1.8 FI).
I am not very mechanical, but I have found the best way to learn something is to do it! I was advised by the person I bought the vehicles from that the '70 had ~ $4,000.00 worth of work done to the motor. The problem is the prior owner removed the carbs and for some reason did not protect the openings from the weather and water got into the motor. I dropped the motor and transmission and took the motor to a friend's house who has had some experience with VW's. We took the motor apart and cracked the case. My questions.... What is the recommended procedure for removing rust from cylinders, jugs (?), valves, etc... I will post pictures shortly of the specific areas of rust... I tried attaching a pic to this post, but I was prompted that I reached the maximum allowed size for the post and to reduce the size of the pic. Reccomendations to reduce the size of pics? Thanks, Brad |

Take a caliper and measure the diameter of the pistons and report back.
Case and crank look good from here. Cylinders will need serious cleaning and probably re-honed. Knock off thebig stuff and let a machineist do the rest. Pistons will clean up, but will need new rings. I don't know enough to make reccomendations on the heads. If it were me, I'd have the cylinders punched out to 96mm, get a new set of pistons to match, and ahve a nice 1911cc engine. Zach |

Take a caliper and measure the diameter of the pistons and report back. Thanks Zach! It will take a few days before I can get back to you on the measurements. I don't have any measuring tools, and by the time I get off work all stores are closed (Oh the joys of living in a small town (IMG:style_emoticons/default/ohmy.gif)). Brad |
