As a project I decided to recondition the head on an 1956 Fordson Major as the head gasket was blowing out exhaust gas and oil at the no.1 cylinder. The engine was fully rebuilt in the 1970ís and it did a lot of work afterwards.
All valves and guides replaced, head skimmed & pressure tested in an engine re-manufacture machine shop.
Injectors reconditioned (including new needle valves) and tested in a diesel repair shop, but I didnít go near the diesel pump.
Cleaned piston crowns etc and took the wire mesh air filter apart and cleaned it out.
I set the tappets. One of the inlet valves had a very large gap when I reassembled the rockers before I set then, but I put this down to a new valve. I ran the engine initially for a few minutes initially and then rechecked and reset all the tappets
On second strating , idling sounded OK but with a little blue smoke (from a new exhaust!) but when I drive it in fourth, thereís a fair bit of wispy light blue smoke. Drove it for around five minutes and just as I was parking it, I revved it up a bit.... then a heavy loud knocking from the engine: I had to shut it down .
So Iím wondering on these two issues:
1)The heavy knock
2)The blue smoke.
Are these two connected in any way?
Is the heavy knocking from a possible troublesome big end which is now been shown up with the reconditioned head or a misbehaving valve with a piston slapping into it or something else?
(The exhaust gas was more black but not as wispy blue before I did the head work.)
