So all the faces have been cleaned up a little and look ready to go. Not measured the liner protrusion, they don't step down from the block so will run with it. All bolts and threads cleaned up and ready to rock. I have latched the exhaust manifold flap fully open whilst it was on the bench. I refitted the spark plugs and filled the chambers with WD40 as that's all i had kicking about and not a drop has passed the valves so a bit reluctant to touch them. Its been in there a good 8 hours now so will check it again in the morning.
Closer inspection of the original gasket shows its almost twisted out of shape in places, cylinders 1 and 4s bore on the gasket is twisted, the same 2 have cleaner piston tops too and number 1 is the one that has staining on the liner. The gasket had huge ballooning in places too, almost as if something had been pressurising it, there is an inner and outer layer to these gaskets so i think/hope that's where my fluid was getting through and mixing. Its 8-10mm thick in places where it wasn't between 2 solid faces. Hopefully a fresh gasket will see it up and usable, at least no worse that it already was 😁

Head all back on, engine up and running. Sounds abit more stable on idle now though a little tappy as i set the clearances wide. The throwing water out of the over flow on initial start up seems to have gone too. Warmed right up and ran for about an hour. No over pressurisation of the coolant. All the old oil has been emptied out and refilled with some fresh 20-50 mineral oil. The Haynes manual (for the 845cc R4) says to do 300 miles then re-torque the head but ill do it tomorrow when stone cold same as i would on a c1j, then reset the tappets again. Hopefully this will have stopped my water/oil mixing issue. Not expecting a jump in compression tbh as i think this is down to worn bores/rings but it will be usable as is if the mixing has stopped.

So far so good. Quite surprised how much extra torque the bolts took, maybe because it's a copper gasket? 🤷🏻♂️ water level hasnt moved a mm, oil looks clean (bar a little trace of murkiness) hopefully just residue as the water isnt missing. Re checked the timing and tweaked it a little and set the idle best I could. I think alot of the parts are old so its a case of balancing up everything, wear/slop in the dizzy and the carb probably arnt helping but she idles ok at around 720rpm and revs really cleanly. Cleaned up a few connections and now the temp gauge is working bar a little slow. If I earth the sensor it goes hard over to hot now so not too worried.
Next on my list of jobs is to try and reinstate/fix some of the original switches. Indicators and sidelights are on toggle switches.
Also word of warning. don't accidentally poke your fingers into the back of the fan, it hurts, alot 😭

And after that work to get it usable, I have confirmed i will be getting the 4 speed gearbox, i offered to buy it but will be swapping it for the the original 845cc engine and 3 speed gearbox. A friend of mine then let me know he had a spare c1j engine sat in his garage after a wall was knocked down on top of it..... Its a 1397cc engine, it is meant for a Renault 5 gt turbo but to start with, if it fits the gearbox, it will be fitted in an atmo setup  |

Cool news on a new motor, is it a healthy one do we know?
Be nice to get some miles out of yours if she is running nicely atm.

Will you be fitting the 1.4 with the gtt turbo? the 1.4 minus the turbo for now. the 4 speed gearbox will be stressed enough as it is. |

Be nice to get some miles out of yours if she is running nicely atm. unsure tbh, but they are very robust and will run on the brink of being totalled tbh. Can be rebuilt for peanuts and will get a once over before fitting anyway. It would be great to rack up some miles, not going to be happening for a while now i don't think. Might be able to drive it to the shops or something soon? (fingers crossed) |

A job well done even if its not going to be in the car long term, be nice to see how much difference its made to the running/power when you go and do your essential shop!

New drivetrain should be nice. I was looking at pictures of R4 & noticed they had revised the chassis on those slightly in front of the transaxle to accommodate extra length of the newer 4-speed transaxle compared to older models?

not sure what you mean on the r4 sorry? its a totally different car with the engine in a different place. You can see the similarities in the layout, ie engine behind the box, gearbox's are totally different though and not interchangeable. The 845 dauphine and 845 r4 engine rotate in a different direction.

Just wondered if you might find the new 4-speed tranaxle to be longer than the 3..

possibly ive not measured, the 330 4 speed is a direct bolt in so I'm told. Ill find out when i get round to picking it up and trying it out. The dauphine was available with a 4 speed later on though.
