Patrol 4.2TD Top end adjustment

Bag Boy,

Setting tappets can be a drama if you're not familiar with it. What is a pretty easy, but long winded job to a mechanic can be an excercise in frustration for someone that isn't familiar with the "traps for young players". Particularly on a diesel. Get it wrong and you could burn out a valve or maybe damage a piston if ya get it really wrong!

I know - I did exactly that as a young man and was in rush to get an 11 litre AEC diesel engine ina big crane ready for a job. Ended up damaging 2 brand new cylinder heads! The boss was NOT impressed!

If you want me to give you a blow by blow description, I will, but be prepared to tear your hair out if ya get it wrong.

Lemme know,

Bag Boy,
As Bilbo says, it's time-consuming. The hardest part is finding that timing marker down by the front crankshaft pulley. The picture in the workshop manual is not all that it would seem. A worklight and a mirror helps a lot.
I rotate the engine over by putting the wagon in 5th gear, jacking up one rear wheel and slowly rotating the wheel by hand to get the piston to TDC mark - not easy, but it works. After doing 6 valves, you rotate the engine 360deg to do the other 6 valves. Just make sure you rotate the engine over in the direction it normally rotates.

$135.00 isn't bad considering the r/c gasket is $50.00 on its own
thats only roughly an hour labour which is about right
if you don't know what you are doing, it will take you a lot longer to do it
it's money well spent

geez some of you blokes must have dodgy dealers.. either that or you go in there with the wrong attitude

just ask for the old rocker cover gasket back .... then u might get someone elses
