5k Lifter Preload

Hi guys,

 

Torqued the head up on my 5k and slapped all the rocker gear in. OH OH valves hit pistons first go. Bugger. I pulled the rods out, they were about 156mm long, so I dug around a bit and found some 150.5 long items and they went in perfect. I'm guessing the longer ones are off an early K engine? (Kangaroosa, you might be looking for some longer rods I think they're the ones I got from you with the cam!)

 

Anyway, the shorter rods gave me lifter preloads from 1.1-1.6mm as best I can measure. For you other 5K builders does this sound about right?

 

I originally measured one at about 2mm but I redid it and got it about 1.6.

 

The longer lengths are on the inlets as well.

cheers

 

Tom.
