    Broken Compression Ring And there you have it. I finally know the cause of my bad compression on number three cylinder. Check out the broken compression ring. When I pulled the cylinder off the engine, the ring fell to the ground, and just like that came the answer to my questions. Also, wedged down between the cooling fins and the engine block was a spark plug someone had lost along the way. Yet another obstruction to airflow. I’m told that this actually happens quite often. I recall I did lose a spark plug socket rubber boot in there, but I think I’d have to think twice about running around town knowing I had a whole plug lost in there.

    Over the past couple weeks I painted the engine tin, washed the new cylinders & pistons, and painted the new cylinders with hi-temp POR-15 Black Velvet. I also took that stuff to the muffler and heat exchangers. While I was painting what I imagine is the heat shrouding on the muffler, the smooth black paint made it easier to see the stamping on the shroud. Turns out this is the original exhaust. It was stamped 1971, with a bunch of other words including “Variant.” Also, made in West Germany. I have no idea how this lasted so long. The thing sure looked rusty, but it certainly is not rusted through. Looks like it’s just surface rust. I wonder if this is one of the galvanized muffler’s I’ve heard about?

    Heads Look OK Finally got the pistons off the connecting rods today. Yesterday I stopped at the Home Depot and bought one of those seven-piece propane torch kits. Supposed to come with a flame dispersal tool, a spark-maker (what are those things called? It’s 1am and I’m tired…) and a bunch of other stuff. So I open the box today and it’s got the propane tank and the brass valve and that’s it. So I sat there debating whether or not I trek fifteen minutes over to the Home Depot by my work or just try to find some matches and light the thing and get on with it. My in-laws weren’t home at this point, and there were car parts and engine tin all over the driveway. I would’ve had to have packed up everything and spent the next hour taking care of what amounted to ten bucks. I scrounged around the garage and finally found a grill lighter, lit the torch and heated up the first piston. This was a suggestion from the Type 3 list as well. Earlier in the week I had stopped by the house to see if I could just get the pistons off. One came off, the rest didn’t want to, even with lots of “convincing.” It wasn’t smooth as silk even with the heat, but I’m sure I wouldn’t have been able to get them off without it. Next step is to actually start reassembly! I have to clean up the areas on the case that seal to the cylinders and pushrod tubes. I’d do the whole case, but I don’t want to get any dirt inside the engine. As it is, I figure it will be a good idea to change the oil almost as soon as I get this going. Maybe let it run for a half hour, then change it. Wow. Run… Let it run… I’m getting ahead of myself. I still don’t know what this car sounds like!

    Did some work on my “new” website tonight. It’s pretty much just a redesign. I moved my firewall and web server over to a new OpenBSD machine, so I figured I might as well clean some stuff up. I have to say OpenBSD has the best built-in documentation of any open-source OS I’ve used so far.

    A Type 34 Didn’t get much done in the last week or so. Took the engine tin to the local “spray ‘n’ wash” and loaded it down with degreaser, then sprayed the hell out of it. Took off most of the gunk, and whatever was left on was easy to scrape off with a wire brush. Took the heater boxes and put them out on the deck to let the sun bake the moisture out of them. Luckily it’s been sunny and in the 80s and 90s recently. After the cleaning, I used the rust remover attachment on my drill and got most of the surface rust off the tin. Guess I’ll POR it and then when I do the engine right in a year or two I’ll have it all sandblasted properly. Hopefully the POR will prevent any further rust in the meanwhile. It all seems like surface rust anyway, probably not much to worry about.

    I had a bit of a surprise from the Type 3 list recently. Turns out quite a few people on the list have used the braided fuel line which I used. It cracks *very* quickly evidently. My immediate thought was to just go through and replace it all once again with Goodyear FI hose, but I think I’m going to wait until I replace the bottom end of my engine in another year or two. This fuel line should be good for a year or more and I’ll just keep an eye on it. I really have to stop being distracted by trying to make everything perfect. I know replacing all this fuel line now would mean I hopefully wouldn’t have to do it again for years, but I need to concentrate on getting the car working for now. I’ve had the car for four months now and I still don’t even know what the engine sounds like! I have no idea at the moment what troubles I’m going to have to investigate regarding the rest of the car, particularly the electrical system and the suspension, so the sooner I get all this stuff done and the motor back in, the better.

    Kevin's Square I ordered one of the fuel filler neck seals from ISP West and it came in very quickly. Very nice piece too! I also got the last length of fuel line from Tom Miller, as well as some replacement vacuum hoses and fuel injector seals. I think they’re the wrong size though, so I’m glad I also ordered seals from Jim on the Type 3 list. Those should arrive soon along with my oil cooler padding. As soon as I get that I can start putting things back together. Just need to wash the new pistons & cylinders and then put some flat-black engine paint on the cylinder fins to help with cooling.

    Stopped by the NH VW Show in Hopkinton last Sunday with my parents & the wife & stepson. That was very very cool. Only one Type 3 represented inside the show, but there was a Type 34 in primer as well. I had never seen a Type 34 in person before, so it was pretty cool seeing one close-up. Lots of very nice Type 2’s as well (as always). Picked up some needed stuff at the swap meet as well — ring compressor (cheap) and one of those sluggers that helps you take off your axle nuts. Also picked up a Type 3 key blank for $9, which is quite a bit cheaper than they usually go for on E-bay.
