a quick Q -
im in the home stretch of my head install.. ive got new lifters and was told by the engine machine shop to "pre-load" them before install; now, is this something that a local machinist could do? i assume so, why not, right?
a light load press should be able to do the job, am i correct?
a simple yes or no would do.. thanks

so, dont compress them at all; just soak in oil, cam-lobe surface face down, overnight. http://****************.com/smile/emthup.gif much thanks

I personally never preloaded mine, as they came oiled and were stored upside down. The Bentley does not indicate or state to preload. Are your lifter bone dry?
but after install let them sit for at least 30 min before starting so they settle. Bentley says it and as do many on vortex.
Good luck. (i"m 6000km after my build and runs great)

I've had lifters in a Chrysler engine take several hours before the lifters bled down enough to let the valves actually close and get some compression. On these VW engines 30 minutes seems to be enough, but it takes longer for most guys to get the cam in, timing belt on and set properly and the valve cover re-installed along with other small parts.

no, theyve come from GAP, and are shipped soaking in oil

i will give them plenty of time to "settle" (bleed down) before i place the head on block
