 Re: 1975 2cv
Ben, since the old stem seals are scrap, a flat screwdriver blade under the edge of the seal then a twist should lift them off the guides. Btw, it's usually best to remove the old seals before grinding the valves in, then the valves will rotate easier... ken. meshking wrote: I've cleaned up the heads nicely, and reground the valves. The valve compressor worked a charm. What I can't work out, however, is how to get the old valve stem seals out to put the new ones in!
Any tips? Also, I've read Sean's tips on using the sheath over on 2cvgb, I suspect seeing how to remove them would help me understand the usage of the installation sheath.
Cheers, Ben

 Re: 1975 2cv
What did I say?? spent yesterday with a hangover so just picking this one up valve stem seals.. the one that fits nicely over the inlet valve is the exhaust one  some come with thimbles to protect the seal from the cotter grooves, if not a turn of electrical tape ...but i usually dont bother and never had a problem. replacement pistons and barrels, the gudgeon circlips can be a b*tch to fit so keep the old ones from the dead pistons handy guessing alls well and the crank turns freely? pinking doesnt come from leaky heads but cuses it as the shock and the heat act like a plasma cutter on the edge of the mating face  Sean

Nearside evidence of pinking, all cleaned up now. Just need to knock the fins off the old barrel and grind the mating face up. Thanks for the tips regarding circlips, lost one of the originals already, pinged off somewhere into the depths of the garage! Ben

 Re: 1975 2cv
Ben, don't forget to lap the other cylinder head as well, since removing metal will reduce the combustion chamber's volume and it's best to have the C.R. on both sides as close as possible. Take particular care to clean away _all_ traces of grinding paste used on the heads, using solvent and a compressor + blow gun. If there's any left lurking in the recess in the head, it will score your new barrels...

 Re: 1975 2cv
Looked at getting the new piston into the barrels last night. Fitting up the rings - should the middle ring go over the spring steel that is already fitted? The instructions seem to imply so, but it seems a very tight fit into the barrel.

 Re: 1975 2cv
Ben, blue box, Kereven branded? I've noticed that as well, they seem to be a much tighter fit than any other makes I've used. ken meshking wrote: Looked at getting the new piston into the barrels last night.

 Re: 1975 2cv
Yes, that's the one. Fits into the barrel, and after much swearing, I got the circlips on too. One side is now done (hopefully I got the pushrod tube seals done correctly). Turns over nicely on the cranking handle anyway (and the valves open and close too, which is nice). Ben ken wrote: Ben, blue box, Kereven branded?

 Re: 1975 2cv
The engine now spins over happily. Got the manifold back on, omitting the tinwear since I'm a novice and not that confident that it wasn't going to leak oil everywhere.
After spinning over, I noticed a couple of oil leaks, all from the two head unions I hadn't done up completely. Oops. Tightened up and seems ok! I get one spark at the plug when it first cranks, but then nothing. Next task is to replace the points and condenser and to reset the timing. Hopefully I've found the correct wires are hooked up.
One other thing I noticed was that the handbrake lever wasn't connected and was resting against the gearbox - when cranking over I got loads of sparks between handbrake lever and drumbrake. Have I missed an earth lead somewhere?
I was surprised to see that the voltage regulator connector has a multiplug connector, which fitted straight onto a solidstate lucas regulator I had kicking about. Or perhaps this means that the car has had a replacement wiring harness at some point in it's life.
