After the excellent advice that you guy's gave me when I was changing my blown head gasket, a neighbour asked me if I could change her's, which I starting to do a couple of days ago. When I stripped it down I found that she had also broken a few rocker arms and so when she ordered a new set she splashed out and also bought hydraulic valve lifters and thrust pads too.
I changed the head gasket and all of the above, and everything was alright until I thighted the streach bolts, because when I tried to turn the crankshaft to set the two top notches and bottom notch and pointer which were very slightly out, no matter how much pressure I put on it, it would not move at all (forward or back). I even removed the rocker cover and tried to push the hydraulic vavle lifters down, but only 2 out of the 8 would make any sort of movement at all Yet before I thighted the head bolts up all of them moved up and down smoothly.
When the bolts are torqued down is it the camshaft stopping them from moving, or because they do not move they are stopping the cam, but why? I thought that the head bolts might of been be too tight, which is stopping them all from moving, but I did them up in stages shown in the specifications (Stage 1 25 Nm, stage 2 60, stage 3, stage 4 60) and I used one of those Skyes Pickivant tools.
In the Haynes manual it states that if you are using new hydraulic valve lifters immerse them in new oil and compress it several times to charge it. Does this mean that there should be some oil in them when they are fitted?
Advice needed.
Cheers
Mike
