I recently had an argument with an automotive technician (i am an
automotive service advisor) about engine prelubrication. As i have
thoroughly read Jack Erjavec's excellent book "Automotive Technology, A
System's Approach" i tend to believe that you have to prelubricate a
newly rebuilt engine prior assembling it again. Technicians here have
the opinion that engine prelubrication is not something very important
for the reliability of the rebuilt engine. I would be happy to read
your thoughts on that. Thanks!
Yeah, Jack is a great author of automotive books and I use his text in my
classes, but there are some things that are outdated. I used to think you
were supposed to lap in a new valve with valve grinding compound, like it
says in the book, but I was recently informed by some of the experts here
in this forum that this is no longer done professionally. Perhaps some of
those guys who are overhauling engines for a living could clue us in on
this as well. I am curious to know what the industry standard is on that
one as well. I have been told that using a pressurized engine pre-lube
machine prior to start up is the way to go on a rebuild and the only
reason to use assembly lube is to preserve the engine's shelf life if it
will not be put into service soon after reassembly. Seems to me using
assembly pre--lube would be the best way to go though. It's been years
since I actually taught engine overhaul and back then we would use
assembly lube, then we would use a pressure pre-lube right before cranking
the engine. I did it that way mostly to teach both methods though.
I find it hard to believe anyone would advocate not using assembly lube or
pre-lubing the engine before start up. And what would be the advantage?

Ok, I miss-read the original post. I thought he was talking about pre-lubing
an engine during assembly. I now realize he was talking about those pre-lube
devices that you can install on your engine to bring up the oil pressure
each time before you start it. That's a whole nuther story. I guess I don't
have any knowledgeable opinion on that one, other than I sure have had good
success with all my vehicles that did not have a pre-luber installed.
