When adjusting the valve clearances on the Patrol 4.2TDi ( Hot .014") what is the most convenient way of turning the engine over by hand to bring the next cylinder to Top Dead Centre ?

arjenki,
For me I rock the vehicle in second high, with the ignition off of course. Flat as possible and not on a brick path it can be very frustrating. Other than that a socket on the crankshaft nut going in an anti clockwise direction. The latter is more excercise and a little bit of help is usually needed for an acurate valve position. Not sure why you are watching for the next cylinder to TDC, tappets are usually adjusted when valves are at their lowest point,
well that's the way I do it anyway. My opinions etc etc

Because
When the valves are rocking eg. inlet and outlet that cylinder is at DTC so now you adjust opp. cylinder..

Richard,
No problem, no offence taken only a
gate. I understood about the TDC method I'm just used to doing the adjustment another way which I find a tad easier, I'm sure there are lots of different ways of doing tappets.
Onward and forward.......................

Adjust them while its idling!!, most mechanics from old school did it all the time.
Watch out for the oil though...Lol
Cheers Axle.

Axle,
Your right about the oil mess, plus if you have a tight tappet it chews the feeler blade to bits and sucks the feeler blade bits into the engine. The old engines you used to be able to do this successfully one were the old Ford and some Vauxhall engines, the Ford Kent engine if I remember correctly.
Any tappets that have to be adjusted with a screw driver and a spanner would be very difficult this way, virtually impossible I would venture to say. Your right Axel takes me back a few years this response, close on thirty, you've got a good memory.

I jack up a back wheel, put it in 5th, and get someone to watch for the TDC mark as I turn the wheel in a forward direction. Seems to go around ok despite the lsd, tho it does need some leaning on to get it moving against the compression. If you go past it, go around again, rather than backwards.
You'll need a mirror and a light to spot the TDC marker on the gear cover, as it's pretty hard to see otherwise. A bit of zinc cream smeared on the relevant markers also helps.
