Hey all
Been searching around for the valve clearances of the TD27 engine
I have found them but now I need to know how to find out when the piston is on the compression stroke, I tried the finger over the glow plug hole with no luck plus I cant get a socket onto the front pulley so I'm winding it over using the power steer pulley
Can some one tell me what I need to do

Take the rocker cover off, and wind by hand till number 4 is rocking and at that crank timing mark it is at No1 firing.
Cheers,

And do the same to find number 4? Have it rocking on 1?

Sweet I will do this tomorrow/today as I have a 4wd trip up above lake Coleridge on Sunday.
My autodata program says 0,35 when hot, Is that right?

1992= silver top. 1994+= black top. The less the clearance the less willing it is to rev out
Cheers,

Just a thought, check the rocker arms arent worn out, the valve heads have a tendancey to wear into the rocker and make them noisey even if they apear to adjusted corectly. Mine are geting pretty stuffed but the local engine reconditioner told me that they can be skimmed.

Usually a half circle on the outer edge. I have seen one full circle it was about 1mm deep
