Subject: Valve Noise
Hey there Listees
The valves in my 83.5 waterboxer tend to be really loud on cold start-up. I
realize that my hydrolic lifters need to be pressurized with oil for them to
correctly "lift" the rocker armes to the correct height, however the valves
are loud quite abit on start-up and sometimes needs to be driven at least
half an hour before they quiet down. One thing that might be contributing
(although I am kind of skeptical that it would be) is that I noticed a slow
oil leak from one of the pushrod tubes. I am not quite sure how the
pressurized oil is conveyed through the tubes and don't know if a leak in the
middle of the tube could drain the lifters abnormally fast (like overnight!).
I was running 15W-40 weight during the summer but now have 10W-40 for the
colder days. I would appriciate any advice, things I could do or if it is
just the way it is! Thanks ahead of time.
