Hi Wilf,

Maybe I should stick to bicycles eh?
I've had the inlet manifold off and from what I can tell the cam is OK but a couple of the lifters are very tight in their bores, ie push them down and they'll pop up when the engine turns over but won't go down again.
I managed to get one lifter out and it seems to me the lifter bore had a (very slight) burr at the bottom edge that I could feel when I put my finger in it. After a bit of work it now moves freeley and with the rocker on, has the whole range of movement.
However I cannot get the other lifter out to check it!
If I ease it donw gently with some taps from a drift, it pops up again ok when I turn over the engine but I can't lift it out of the bore. Any advice?
It seems to me that MAYBE in a previous life, the engine had a cam problem that caused the two lifter bores to have this ridge on the bottom, and the problem was not addressed before the engine was built.
There's plenty of assembly lubricant on the parts, and the lifters look new, so I think it has been rebuilt.
