Ford 4000 3 Cyl Diesel Oversize Pistons
Hi All.
I am looking at my Grandfathers Ford 4000. It has low compression and is burning oil so I have prepared it to remove the engine with a view to reconditioning it. My understanding is that these 4.4” bores were never intended to have oversize pistons. I would be grateful if anyone could offer some advice as to whether these engines are suitable to use oversize pistons in and whether they are available or not in the UK.
I work in engine reconditioning so the work is no trouble - even if oversize liners are required to get back to standard pistons. However, provided there is enough wall thickness I can’t see why a +0.010” or +0.020” set of pistons and rings shouldn’t do the job sensibly. Perhaps there is the chance of liner corrosion and the extra boring may uncover something undesirable. But of course I have never worked on one of these so this particular engine is all new to me. So I am keen to take in any information anyone may have.
Thankyou kindly in advance.
