I spent all last winter under my WC 56, took it to Normandy for 2004, by the time I had got to Horndean it had cracked the exhaust manifold, and used all the oil and notice that oil pressure was low, oh and had a flat tyre.
So pumped up tyre and filled with OKO?
And then checked oil level every day.
The Dodge then ran perfectly every day, and out performed the jeeps in the dunes.
Last winter checked cylinders and replaced piston rings, checked crank and replaced big end and main bearings with the engine in situ. Found bearings just starting to fail.
And replaced exhaust manifold.
Engine still had low oil pressure, found oil pressure relief spring in two pieces.
I have had problems with leaking brake clyinders as mentioned honed cylinders and problem cured.
I hope that you cure your problems.
Looks a nice dodge, as does the Carryall.
