Hydralic lifters almost never get out of adjustment but it won't hurt to
try.

Forgot to ask in previous post.... How does the "static"
adjustment work with hydralic lifters? All of my old cars
(with hydralic lifters) never had adjustments on the rockers.
So it would seem "odd" to me to have both. Anyways, if
so, I wonder how that would work? (static adjustment
with hydralic lifters) - do the lifters stay pumped up, or
do you do that "one turn" into the lifter into the colapsed
mode?










If you really have a lifter that is clacking it may be collapsed.
With the valve cover off you may be able to get a better feel for the
source
of you noise. Valve train nise can be felt and changed by pushing on the
rockers while the engibe is idling. It is messy. They make clips that
can
be placed on the rockets to limit the oil spray.

I brought this up last year, and concerned about it again.
Mercruiser 3.0L Alpha one (130HP?). Does anyone
know if this engine has hydralic valve lifters, or adjustable?
I'm assuming that they are adjustable. Anyways, 3 questions:

1) Adjustment procedure, is it 1/2 turn, 3/4, or 1 turn
past zero lash ? Whats Mercruiser say, whats common.

2) How do you get the valve cover off with that bracket
on top? There is a big plate steel bracket on the left
that has a wing that bends in to hold throttle cable.

3) What the best way to turn the crankshaft for the
valve adjustment? Take plugs out, and just grab
the belt and man-handle it around like that ?

I'm concerned about this clacking noise that I've been
hearing since last year, ahortly after I bought it new.

Also, been hearing a "huffing" noise near the carb and
manifolds - sounds like one cylinder is "huffing" through
the carb or something. Hard to tell if its one "huff" for
each cylinder at idle, or just one cylinder out of four.
The boat runs fine. Idles well, accelerates, high speed...
There is nothing wrong with the way it runs, just wondering
about these noises (at idle) - this valve noise, and this
"huffing" type noise near the carb.


Thanks!
