I'm having a bit of a brain fart moment.

My engine has solid lifters. The head was recently rebuilt. But I'm not certain it was done 100%.

What's the easiest way of checking the valve lash? I want to check the clearance as I'm not convinced the valves are fully closing.

I've got the leak down tester to check as well, but if it's leaking at the valves I want to check the clearances.

I'll contact the fella who did mine and ask if he has it written down somewhere.

typical figures are 0.2 inlet 0.25 exhaust, or 8/10 thou.

turn the engine over till each pair of lobes ard pointing away from the bucket.

Wouldn't know the clearance settings on these with solid lifters but as WP says it's very easy to check with an angled feeler blade. You need to measure the actual gap distance accurately and subtract or add the correct amount from the shim to achieve the correct gap.

I have the clearance figures on .25mm inlet and exhaust for the cams I am using. It was more knowing that I needed angled feeler gauges rather than taking anything apart. I've never done the fiddly bits like the valve lash on this one before. So just needed a confirmation of what I need!

you don't need an angled feeler, but they do make it easier, all you need to do is pop the cam covers off,

from what I recall of the procedure, turn the engine till the lobes of inlet and exhaust are rocking on the tappets (i.e inlet opening and exhaust closing)

number 4 clearance on both inlet and exhaust can then be checked (not forgetting that 1 is flywheel end)

check the clearances and make note of them.

rotate engine till next cylinder's pair of lobes are rocking, 1 3 4 2 check valves on 4 2 1 3

You pressurize the cylinder to a set pressure using a supply of compressed air and then measure how quickly the pressure leaks down, basically the slower the better! Similar to a compression test really but measuring how quickly the pressure disperses.
