Looking for some ideas here !  In the last few months I've had to do a ton of head work to my 2003 warrior. Replacement 2nd hand head fitted (skimmed/tested) using my old camshaft and my old caps. New tappets which I've set and checked a few times hot and cold. Car runs really really well, good power and pick up and good mpg.

Problem is it rattles like an old tractor when I start up ! Bad when cold on idle but becoming noticeable even on hot idle too and sometimes under load. Rev the engine hot or cold  and the rattle pretty much fades away.

Does it blow a black smoke from exhaust....possible ignition timing out a tooth.

No there's no smoke at all, everything appears really healthy ... apart from the rattle !

Did you check to see if there was any play in the big ends when you did the top end, also was the head marked slightly on 1 side of the piston crown ( generally no's 1 and /or 4)

The valve caps located in the ends of the rockers could have shifted.

Wel I took the rocker off and couldn't see anything untoward at all. Reset the tappets at 18 cold rather than 25 hot as by the time you strip it down and get to the last tappets its cooled considerably anyway ! Still has the damn rattle.

Used the truck and all was well ... but ... next morning it wouldn't start. Its always started first turn. Eventually stuttered into life and I then found a vacuum pipe at the rear had popped off. Next morning it started ok though not as quickly as it used to. Reckon I'll change the glow plugs before winter sets in.

As for the rattle .... that remains a mystery  Huh
