Several of the lifters would bleed down within 10 seconds, with only the weight of the pushrod on them
zoomzoom wrote:, I have always used a firing order/TDC method, in which I set #1 at TDC-compression stroke, and adjust both valves for that cylinder, rotate the crank 90 deg's, and adjust both valves for the next cylinder in the firing order. This always seemed like a no brainer to me, as TDC-compression stroke should be a guaranteed point of zero lift... --- OK for most mild/hot flat tappet, BUT at tdc you are not on the center of the base circle, with a big cam you will find that this method will put the lifter on the opening/closing ramp and fudge your adjustment.
This engine does have a fairly stiff dual valve spring, and I would like to hear if anybody thinks that high spring pressures are harmful to hydraulics. (No spring pressure spec's in front of me, but I recall it's at the top end of what comp recommended for this cam.) --- So long as the springs you have are 'basically' close to what the maker suggests the lifters will be perfectly fine.
Please no lectures about going to a solid lifter cam, as I am assembling this for somebody who is as thick as a brick wall, and thinks this is the low maintenance way to horsepower happiness. --- In this case then hydro is great!! keep the plunger adjustment the way you have described for many many fuss free miles
