Tappet Adjustment.

Hi just a couple of brief questions.

When adjusting or checking the clearances of the tappets on a Discovery 300
Tdi, should the engine be warm/hot or cold?

Second question, is the recommended gap .020mm on both inlet and exhaust
valves?

I have serviced the engine before, oil, filters, et al, but never done the
tappets, so it's new territory for me.....

Thanks in advance for any help....

Same, same i.e. hot or cold and in/ex the same, be aware that valve stem cap
could be worn and need replacement, get a few in advance.
regards
ivan

in an emergency and strictly short-term, you can adjust a rocker with a
missing cap so that it bears on the valve. This is better than having it
much too loose.

but replace the cap ASAP, it's doubtless there for a reason.

Thanks to all who replied I have checked on the feeler gauges, they are
imperial / metric type, so the closest I could get to the required .20, was
..206 which I hope will be fine, I also replaced all of the valve cover caps
because 1 had worn totally away. Everything seems fine at the moment, well
it started and ran ok and the obliglitory puff of smoke at start-up was
absent, which I hope is a good sign.

Anyway thanks again.
