Content-Type: text/plain; charset="iso-8859-1"
From the first paragraph of my article
(The symptoms of the lifter problems I am talking about in this article are
low idle when cold, hard or not starting hot, poor performance when the
engine warms up and the power (vacuum) assist brakes may not work as well at
times because of the low intake manifold vacuum. These symptoms can be
caused by improper hydraulic valve setup.)
the air may remain in the lifters and never fully bleed down. the new febi
lifters don't come apart and that's the only brand out there at this point
I'm aware. I would add some shim under the rockers to do this I shop for a 1
inch OD washer aprox .040ths thick and drill a hole in it large enough to
install it on the rocker studs. This sets up the rocker so the geometry is
correct with the .0 lash hot setting. the lifters will quite down and if not
you need to replace a few more

Calle,
I did not fill the lifters with oil during assembly. I soaked the
lifters in oil prior to assembly. I also tried to poke the little
bleeder hole, but I'm not sure if I got the oil in.
I'm wondering if the air pocket in the lifter will slowly bleed out if
I drive for another few thousand miles?
Right now, I'm driving the van to work and it's fine. If I park the
van overnight, there is no problem with the power. It's only when I
leave the van sitting for about 3 days that I have low power. Is this
how the engine behaves when there is an air pocket in the lifter?
When I look at this article by Boston Bob, I don't see that I have any
of the symptoms listed in the article. However, I don't have
experience with these things.
http://www.bostonengine.com/articles/hydraulicll.htm
I have poor performance when the engine is cold and has been sitting
for 3 days. My performance is fine when the engine is warmed up or
used every day. It seems to me that something is leaking out of the
lifters. I'm not sure how the lifters work, so I'm not sure if there
is oil leaking out of the lifters after it has been sitting.
I have collapsable pushrod tubes on the two lifters I replaced, so I
can remove the lifters from the case fairly easily. However, I'm not
sure what to do with the lifters once I've taken them out. I did not
take the lifter apart. Boston Bob's article seemed to focus on people
that took the lifter apart. Though, since my lifters were new, there
probably was not oil in the lifters, so it seems I should somehow get
oil into the little guys.
Regards,
Craig
