Bloody hell. Didn’t you retorque them in your last video?  How did it get so far out has it punched a hole in the rocker cover?

 

actually, that was the one bolt you said was loose and needed tightening. Has it stripped its thread?

Yes, it was that one. It must have already been failing, hence being able to tighten it up again. I pulled it out further for the photo, but it was well loose.

Options

1) Dismantle the engine, see if a thread insert can be used. It's a cylinder head and barrel off job to even investigate.

2) Grab Elly's original crankcase and dismantle this engine, so the barrels, pistons, manifolds and heads can be switched over (has done 170,000 miles, not run for 8 years, is mostly in bits)

3) Chuck in my entirely unknown spare engine and hope for the best.

4) you jokingly said in an early invacar video if a 2CV engine would fit, now I guess now we ask the question can you fit an invacar engine to a 2CV? :mrgreen: (plus a head off the spares engine because spark plugs)

why was Elly's original engine removed in the first place? if it was due to an issue not with the crankcase then it may be viable? :)

Put the old spare in  as you’ve limited time before Croatia.

this is the engine that had the 50cc upgrade isn’t it?

£1500 option 4.  https://www.ecas2cvparts.co.uk/engine-2cv6-reconditioned-exchange-p-965.html?WSid=e4fc849a06317f6b352661de1cf3d65a

I think engine swap has to be the sensible ideal. Not sure I fancy doing a roadtrip on a fresh recon engine! Burton sells 652 recon units I think, so as long as the spare engine makes it to The Netherlands (first stop) I'll be fine!

Check the engine out on the bench, make sure it all moves and no obvious gunky signs of  head leakage. Put in new points and plugs and do the valve clearances. Oil change and fit- what could go wrong! Probably put the carb you know back on.

 

burton is €1900 for the 652

Options 2 and 3 seem to be the best considering the time you have. I'd say fit the unknown engine and hope for the best and fix the old one after the trip. If time allows, fitting the large cylinders might be a good idea, however I think checking over the mystery engine by iteslf will take long enough.

Seems Elly doesn't want to go to Croatia and see her friends :( Hope you can get something sorted out but in the meantime here's something that might cheer you up

It's based on the 1/76 Oxford Diecast model with a few cosmetic mods. Not 100% accurate but a good enough replica in this small scale.

That was quick! :) does your compression tester fit 2CV engines?

im guessing you could swap over your 652cc piston/barrels/heads if there is no compression?

It does, though engines that have rested often have weak compression until they get a bit of fire in 'em. I will get some Before and After readings.

And yes, I could swap everything over. I don't really want to go down that road though. The more I do, the more potential there is for damage.

Compression results. 60 one size, 0 the other. Promising! The side that is 0 is chuffing out of the exhaust as it should though. Very odd. Maybe a sticky inlet?

Sadly, I then decided to check the oil pressure switch is working. It wasn't, so swapped them. Works fine with the test light, but I can't get it to work with the car's own wiring. My brain isn't up to working out why. Had to stop.

Is it worth checking the valve clearances while it's all still apart? Might be a very slack inlet clearance (fingers crossed).

I was also going to suggest maybe trying a fresh stud in the other engine. If the one in there is a bit corroded/chewed/worn, a new one might just bite with the remainder of the thread.
