This is great isn't it? I bought a new exhaust. Had some leak issues with it or the heat exchangers. Took them off. Decided to dress the 40 year old stub ends. File too small so I ordered the biggest one I could find. That should do it. While waiting for that, as the exhaust was our of the way I thought to address some oil leaks. The dipstick bellows a bit sloppy but mainly the oil filler/case join was leaking. Out with the oil, off with the filler, off with fan and fan housing. Now I'm thinking I have so much off the engine I have room to pull it off the gearbox and change the flywheel and oil seal. I only had a pop on overrun to start with. I blame all the free time waiting for post.
I had similar many years ago. My beetle had trouble starting. Rather than just replace the starter motor bush, it ended up in a full rebuild and increase from 1200 to 1641cc!
A slight knocking noise and I rebuilt my 1955 to 2020 and only kept the case and crank! Then sold it because it was a high revving type-1 max HP motor, not really the thing to have in a bus and started from scratch with this type-4 one for more cc, better cooling and low rev torque. I shall have a file of those stubs in a mo while the rain is holding off.
Trouble is as those are something like PVC. In contact with hydrocarbons they will lose their plasticiser and go hard. And over about 65 to 80 degrees C they will melt. If car manufacturers could use the cheaper option they would. Instead they keep PVC type plastics for wiring looms..
The one have fitted came from heritage and is made from nitrile butyl rubber. It's gone from firm to squidgy but is as strong as ever, no splits, no cracking. It's almost OK!
Nice morning, I've been up since 5am, it's a lovely day for some car park heat exchanger fitting. When I say fitting, I mean making them fit, not actually fitting them. That means filing. I knew they weren't right but I didn't think they'd be as wrong as they were. First one, first tickle... More... And eventually...i Other one... This one was worse... That didn't take all that long, 20-30 minutes and a £25 file well spent I think, these have always been a nuisance and I've got a big sharp file for my tool collection. They were both off in the same direction, almost as if in a previous life the exhaust had been whacked from behind. Peaked a bit early today.
Gave mine a fettle before they went back on due to all the dirty soot marks I found on the heads when they came off... resorted to a bit of felt tip to finish off as when all shiney it was hard to spot the 'low bits' Took a little off the lugs too just in case...

You used a big file to do both at once and keep them on the same plane? Only asking because it was really obvious with a big file, no need for felt tip.
Yeah.. big file over both.. but couldn't do all of the pipe at once due to width of file done as going diagonally and in line and in plane as best as I could see.. Gave it a very light 600 grit sand to polish off too .. and a smidge of exhaust sealant to burn and fill any remaining gaps.. Sent from my SM-G930F using Tapatalk
Another leak where I fitted my linkage extension to the case. I knew it was risky at the time but there was nothing to fix it to apart from case fixings. My sealant arrived today so the best I could do was seal up the bracket/ hole/ washers. Another small step. And I cleaned up around the pushrod tubes ready for that job.
Seals came today but it's still raining. My replacement flywheel not so good as I remembered, has a seal wear groove that won't buff out. Seal is 10mm deep, funny - I remembered them being 12mm. From sliding it onto the flywheel I think a 12mm one might work without the wrong bits scraping the flywheel...or a 9mm one if there is such a thing. Or a 1mm spacer ring under a 10mm seal. Anyone done this and found a way of avoiding the groove?
I wish I knew how deep the recess is for sure. I'd rather spend on a few alternative seals than be befuggled with the engine out. It's a CJ marked case if it makes any difference. I know earlier cases varied but I don't know about these later 2l ones. @SundialCamperSpecialists fitted the last one, I recall "flush or knocked in?" and would have answered knocked right in. Or I might have imagined that!
Think I've got my old knackered CJ case down the side if the garage.. I can hoick it out an measure for you over the weekend if any use Sent from my SM-G930F using Tapatalk
