Thanks for getting back. "Piston to valve aproach... " I don't get what you are saying there?
This is the term used for the piston coming up to top dead centre of the bore (and so, approaching the valves)
That's too short and fast for my tender little brain. Can someone elaborate some more for me?
A discussion could be interesting here. Thanks
@@leh3827 of course! What would you like to know?
@@hackengineering5586 Do you create solid lifters or hydraulic lifters?
@@hackengineering5586 Are the lifters you make solid or hydraulic? I got crossed wires in there somewhere. Thanks for your patience.
@@leh3827 in this video you're seeing hydraulic. We do also offer solid lifters for many BMW engines, but not mentioned in this video.
During engine building we 3D print a solid lifter to take out any misleading hydraulic issues. This is purely for measuring purposes, and not for running the engine with.
@@hackengineering5586 Thanks for setting me straight on those things.
I would like to ask you the main hydraulic lifter installation question I have come across. Do you soak lifters in oil and pump them up before installing them. In days gone by Everyone said toss the new or freshly cleaned hydraulic lifters into a pan of oil, and pump them up using a push rod while keeping them submerged, before putting them into the block.
I am working on a 1996 Chevrolet 5.7L Vortex. People are saying set zero tolerance and then the prescribed lash adjustment (3/4 turn more than zero tolerance).
I personally can't see any problem doing it with pumped lifters besides the fact that you would have to wait for the lifters to bleed off before running the motor. Do you see it this way or am I way off?
