2005 Bayliner 175 3.0L/A-1 engine noise - valves ?
 

So I finally got about 20 hours (I think) on my new 2005
Bayliner 175 Capri, and within the forst 10 hours, I
noticed a noise in the engine, and it seems pretty
pronounced at idle. It like a rattling noise, but the
best way to describe is that it sounds just like that
rattling sound of a diesel engine. I stuck my head
clean down in the engine compartment, and it seems
like its coming from the cover on the left side below
the head (where I think the lifters are at). This is a
Merc 3.0L straight 4. I'd "like" to think that it is
valve lash, but that "rattling", diesel-like sound has
got me worried, because in my car engine days,
this sounds just like piston slap/wrist pin type noise.
And when I really wedge my head down in the
engine compartment, it "almost" sounds like its
loudest from the back of the engine near the
flywheel/coupler, but I can't say that for sure.

Is this normal? - can someone shed some light
on the nature of this sound, and why it sounds
so much like piston/wrist pin type noise, and
not like the lifter noise of the old V-8's of years
gone by? Could it be just the physical layout
of the Merc 3.0L straight 4 and its valve train
layout? And if it is valve lash, is it normal to
need adjustment after 20-ish hours on a new
motor?. And one last question, does anyone
know for sure if the 2005 Merc 3.0L has
solid lifters, or hydralic lifters ? Is this
something that Olympic Boat centers is used
to doing in the fist few hours of new Merc 3.0L's ?

Thanks in advance!

It might not hurt to have somebody actually listen to the engine and
render an opinion after hearing the noise. It may be a "break-in" issue
that is supposed to be dealt with at X hours. Anything in the owner's
manual that indicates a service adjustment at this short interval?

Olympic can probably answer your question authoritatively and
accurately, but if you want a second opinion try calling Pat of Pat's
Marine Engines over at Nickerson Marina.

New boat: definitively take it to the dealer. If you think it could be the
valves, they won't get any better. It's not a common problem, but I did have
a valve fail in the first few hours of operation of my 1998 Bayliner Capri
1950CL.

"Wiz",
It seems odd that an exhaust shutter should fail on such a young boat, but
that is what your problem sounds like to me. The sound usually diminishes or
goes away while the engine is warming up and starting to run smoothly.
Definitely get the dealer to listen to the noise and resolve the problem.
And don't fall for the old "They all sound that way" cop out.

But the exhaust shutter is on the other side, right?
This sound is loudest on the starboard side, from
the long sheet metal cover on the block below the
head. Loudest at idle, turns into a ticking at speeds
a little over 1,000 RPM, and can't hear it at speeds
faster than that.

In your first post you suspected valves...hopefully it's not that serious,
but your engine could be beating itself to pieces. Stop the guessing game
and get it to the dealer....
