Re: Old Jeep drivers beware!
OK, but if you have a hydraulic lifter that pumps oil through the
pushrod that doesn't really have anything to do with the face of the lifter.
I've heard for a long time that modern oils were tough on old engines,
and that Hot Rod article is the first thing I've seen in a major
publication where they gave some real evidence. Does it effect Jeep
engines? I don't know, I suspect if you are driving around in a ******
Jeep with an F head engine you should be concerned. If you are driving
around in a 96 Cherokee with a 4.0 I wouldn't worry about it (and I
don't, got 300,000 miles out of my first engine using regular old Pennzoil).

Re: Old Jeep drivers beware!
My father grew up on a farm, neither his father or his brothers were
drafted because farming was considered a strategic occupation. However
Dad went to collage and then spent a short stint as a collage
professor... and was drafted for the Korean War.
My other Grandfather was what we would now call an avionics engineer for
Bendix in Teterboro NJ, kept trying to join the Navy during WWII,
finally the recruiter told him "Mr. Noxon, if you insist we will sign
you up, but then you will be assigned to doing exactly what you are
doing now but making a lot less money!" Granddad gave up on the idea of
joining the military!

Re: Old Jeep drivers beware!
A lifter has a top and a bottom. There is nothing ambiguous about a
'flat top lifter'. It sure isn't a 'flat bottomed lifter'.
I can only find one example of a 'flat top lifter' in google and that is
a special insert in an opel racing engine to do away with lash shims.
So I ask once again, "do any Jeep engines use flat top lifters"?

'flat top lifter'. It sure isn't a 'flat bottomed lifter'.
I can only find one example of a 'flat top lifter' in google and that is
a special insert in an opel racing engine to do away with lash shims.
So I ask once again, "do any Jeep engines use flat top lifters"?

Re: Old Jeep drivers beware!
A lifter has a top and a bottom. There is nothing ambiguous about a
'flat top lifter'. It sure isn't a 'flat bottomed lifter'.
I can only find one example of a 'flat top lifter' in google and that is
a special insert in an opel racing engine to do away with lash shims.
So I ask once again, "do any Jeep engines use flat top lifters"?
