It’s going to be a stunner when it’s done Philippe, looking forward to the engine strip and rebuild!

Hello men
an update of the restoration.
The past week I took the engine apart...bad news!
When honing the second cylinder bore it turned out there was a major damage all around the bore.
There must have been water in the second cylinder when the engine was stored resulting in a deep rusty indentation.
There was allso scoring visible on the shell bearings of the cranckshaft, as wel on the main bearings as on the bearings of the connecting rods.
I guess the engine has been neglected in the past and the oil has become too old and dirty and that's the result.
It turned out that 3 of the 4 pistons were the same and one was different...
The first piston has no T -slot, the other 3 have a T-slot as normal in these engines. I think that the first piston was heavier than the other 3. It must have been changed sometime in the past.
There was also a lot of carbon built-up in the heat expanding slot of the pistons. The first groove of each piston is ment to stay empty to allow the piston to expand when heating up so there's no piston ring in it.
One piston was cleaned, the others were left as I found them.
So, I have a bad engine...
I don't want to get the engine rebored and the cranckshaft to be regrinded because that's waiting and asking and getting promises when it will be ready and then new promises and more waiting...
NO, I'm sick and tired of hearing false promises about when the work will be done or when the parts will be available.
Don't get me wrong, I don't mind waiting for a job to be done but when the time comes, I expect it to be ready, I've heard enough excuses why the work isn't done.
But I have a solution!
Next week I'll get a refurbished engine block (new cylinder liners, standard bore size) and a refurbished cranckshaft with new bearings, new valves (valve seats cut), new valve stem guides, new pistons and piston rings.
It will cost me several thousands of Euros but you know what they say: time is money!
I won't have to wait and I'll be able to continue rebuilding the engine.
I'll be able to put a "new" engine in the jeep in order to ride it without troubles...at least that's what I'm hoping for.
More news to come soon!

Re: Restoration of a 1942 Willys jeep GPW Ford
Hi men
the latest report of the progress:
I bought a refurbished engine block in order to replace the one I have.
It has new cylinder liners, new valve stem guides, new valves. I also have new pistons and piston rings, a refurbished crankshaft, new bearings as wel for the crankshaft as for the connecting rods and new timing gears and chain.
It's almost a new engine or....at least that's what I'm going for.
It turned out that one of the connecting rods was wrong! The number 2 conrod was actually a number 1 or 3 that was mounted to look like a number 2 but with the oil hole on the wrong side so the oil was splashed against the inside of the piston where the T-slot is located instead of the other way around.
OK, it's an old engine and who knows what happened in the past...anyway I hope I can bring it back to a proper working order.
For the moment it's almost back together and the only thing I have to do is to paint it and go for the final assembly.
Previous friday the gearbox was delivered! A heavy lump of metal but easy to install on the chassis.
Last saturday the Firestone tyres finally arrived together with the inner tubes and the rim flaps.
I had to make some adjustments to the rim flaps because the ones I received had the valve holes in the centre instead of in the side wall as they should be.
Installing the inner tubes and the rim flaps is a pain in the a... I couldn't get the rim flaps around the inner tube and in the tyre...until Christine had a wonderfull idea: take the rim flaps inside so they can become warmer and easier to manipulate. IT WORKED ! I must admit that she has great ideas in order to make life easier for me.
So finally I was able to make a rolling chassis!
After I installed the wheels, I rolled the chassis outside, so far so good but...I needed help to get it back in the garage so my wife gave me a hand. Christine realises that she will have to do this a few times more in the future...
And yes Bill, Thorben is still helping but only to guard the garden gate, just imagine what would happen if he didn't see anyone coming in the garden! No food as punishment! Disaster !!!
The work continues as long as the temperature permits it.
More news to come!
