David says the compression is not there to start the engine. That means a rebuild smelly. You can't make compression when the jugs are worn out.
Don't be so sure that you "can't make compression when the jugs are worn out." [-X
I've got a 1600 single port pushing Joy's 75 Super Beetle Convertible down the road that I built with badly worn jugs and old pistons. I just honed the dog poop out of them, put in some new rings and they were "good as new" . . . ok, more like "good as 3/4 worn out" but it ran. Still runs. 9 years and
miles later. Still runs. Has a little blow-by. Always has. But is runs. Burns a little oil. But it runs. It's been in three differnt cars . . . maybe 4. I've lost count. When you've had as many as 20 VWs in the back yard at one time, it all kind'a runs together. I ran this engine in one of the cars 2 different times. All of the cars were daily drivers. I don't have any idea how many miles this engine has on it 'cause two of the cars it was in were Supers. Super's speedometers don't work. OK, that's a pretty broad statement and I'm sure there are some that do . . . somewhere. Most don't. There is one little plastic gear in there that cracks. It's a law. After 30 years the gear must crack. Very few of them break the law! Then they either stop working all together, or stop a while, run a while. Anyway, I don't know how many miles this engine has racked up, but it's got to pushing 90-100 thousand miles. And it started out with worn out jugs!
Not only were the jugs worn out, but the heads were cracked between the valves. Cracked so bad Ray Charles could see the cracks. Took 'em apart, cleaned 'em up, lapped the valves . . . used some lapping compound on top of an old jug and lapped the jug to head sealling surface . . . put 'em back together and bolted 'em on.
The bottom end was a different story. New heavy duty oil pump. Used cam, lifters and crank, and rods but they were checked out and showed no sign of wear. Brand new GERMAN OEM bearings. The case was checked by an old timer VW mechanic. He machined the bearings to fit the case instead of cutting the case to fit off the shelf bearings.
Anyway . . . what I'm trying to say here is . . . even if the jugs are worn out it doesn't mean the engine won't run. And it may have low compression for other reasons anyway. If a valve is too tight and not closing all the way or if a valve is burnt, that cylinder isn't going to have much compression. It's like trying to blow up a ballon that has a big hole in it. Also, if a head is really loose, you can loose a lot of compression between the jug and head.
Don't assume low compression is due to worn out jugs. My experiance has been that the heads will give you problems LONG before the jugs are too worn out to run.
I'll see if I can get over and help get it running sometime in the next week or so. I don't think I'll be able to Saturday. I've GOT to pull the engine on Homer and fix the oil leak. It's almost quart a day habit now. I'm spending more for oil than I do for gas. Not only is it costing a fortune, I think the EPA is looking for me! When you have a drop of oil hitting the ground every couple of feet your pretty easy to track too! Anyway, Saturday is not looking to good to get over to the Smelly Cat abode . . . and Sunday is Mother's Day. So . . . maybe one evening next week? . . . The Smell Cat Mobil WILL live! Can't promise people and animals in the immediat area will, but the car will. SOON. :thumbs-up:
