alls good did it this arvo

Presume you're using a feeler gauge to set your tappet clearances & not working with a shim & bucket setup......

You can set the clearance at any stage on the cam as long as it's not the transition to the "lumpy" bit.

Sorry, my fault I am used to working on L series obviously with over head cam. He He

Same principal applies though, you just cant see the cam.

Yes you are correct:
No. 1 TDC: Adjust valves 1,2,3,5 (counting from front of engine)
No. 4 TDC: Adjust valves 4,6,7,8

Sorry still getting used to this A series stuff.

if you cant see the cam how do you check the other 2 cyclinders, or does setting it from from the system
No. 1 TDC: Adjust valves 1,2,3,5 (counting from front of engine)
No. 4 TDC: Adjust valves 4,6,7,8
correct all cylinders

Good, if you are not sure which four to adjust each time just look at the cam lobes and adjust the 2 that are pointing upwards in a V shape (Will be either No1 or No4 cylinders).

There will also be another 2 cam lobes one on each of No: 2 and 3 cylinders that also point out in either side of the V shape and you can adjust those as well.

When you rotate the crank 360degrees you will pick up the others.

aahh that helps a bit.

Yes, when the timing mark is on "0" that is Top Dead Centre (TDC) and the valves are fully closed on the cylinder that is firing (which will be either No: 1 or No: 4 cylinder).

When you do the distributor timing, it is set at about 10 degrees Before Top Dead Centre "BTDC". This allows time for the burn to expand and be compressed before sending the piston back down the bore.

If you are setting the tappet adjustment you should be able to put the timing mark at TDC and adjust four of the tappets then rotate the crank once back to TDC and adjust the other four.

Hope tha helps.

to get the tcd (valves) is it the timing mark set at 0 degrees? im confused with setting the clearances. i tried understanding this method but got confused.
clicky
he says that when 2 is on the rock check 3; 1 on the rock check 4; when 3 is rocking check 2: 1-3-4-2, but then how do you find out when they are on the rock??
