If you read the initial 'bad day on the bay' post, you are aware that I had a

Inspected the boat on Monday. Found the cause of the smoke to be the overheating
of the insulation on the wiring harness which was laying on the exhaust elbow.
(Probably done by the manufacturer.) Also, the lack of water going through the
starboard exhaust caused the rubber section of exhaust pipe just below the elbow
to melt out, The smoke was due to all the melting rubber.

I removed both sets of risers and manifolds and the other damaged parts on the
starboard side of the engine (5.7L Mercruiser). The wiring harness was
repairable. The riser didn't have an obvious plug.

When the manifold was removed from the starboard side, I noticed a discoloration
in the exhaust port of the third cylinder from the front. By discoloration, I
mean a reddish (rusty) color. I didn't feel it, at the time, but today the
mechanic at the marina said it was wet when he looked at it a day later. The
mechanic didn't do anything further than look at it and feel the wetness with
his finger. I also, today, felt the same port on the manifold, and it was also
wet.

The mechanic wants to run a compression check on Monday. Now I'm concerned that
what I thought was a plugged up riser may be something much more serious.

Questions:

What could cause a wet exhaust port on one cylinder?

If there is a problem with that cylinder, how could it have prevented water from
going through the riser?

If I try to pour water through water channels in the riser, and it either comes
out or doesn't, can that diagnose a plugged riser?

The engine didn't sound like it was missing. On Monday we'll start it and see
what comes out of that exhaust port. (Without manifolds and risers, that should
be a disquieting experience!)

Thanks for any help. Smart assed comments about my lack of V8 expertise will
also be accepted.

Totally uncalled for Krause and a perfect example of the type of person you
are. Shame on you. You are without an ounce of class.

John I wish I could help you but I am not a mechanic. I am sure others in
this forum with more mechanical experience will help you.

Questions:

What could cause a wet exhaust port on one cylinder?

I asked &;

The cyl head casting is not too thick around the exhaust ports, so in
salt water, raw cooled, cast iron, etc etc. The "problem" with raw water
cooling is you can't let the salt water get too hot or the salt drops
out, around the exhaust port is where the most heat is.


If there is a problem with that cylinder, how could it have prevented water from
going through the riser?

Probably shouldn't of itself but; is there is salt buildup inside the
head generally? that would. Don't assume this particular leak was the
only cause of the overheat.


If I try to pour water through water channels in the riser, and it either comes
out or doesn't, can that diagnose a plugged riser?

I guess it can indicate a flow path, but it's less than pin holes that
develop near the hot spots which allow salt buildup inside & rusting.
The real fear is that the weeping very tiny "just looks a bit moist"
leaks will eventually allow water back into a cyl between uses, then an
hydraulic lock on start attempt is the risk.


The engine didn't sound like it was missing. On Monday we'll start it and see
what comes out of that exhaust port. (Without manifolds and risers, that should
be a disquieting experience!)

You can have a bad leak in the exhaust port &/or manifold & still run
OK. The exhaust pressure/flow keeps any water going in the right
direction. Starting it will not help much, nor a compression test, you
need to make sure the exhaust port (downstream of the exhaust valve) is
not leaking & a run or compression test won't help with that.


Thanks for any help. Smart assed comments about my lack of V8 expertise will
also be accepted.

I know it is scary bananas but if you take the head or (s) off & take
them to a machine shop, they will bolt them to a flat block of steel &
then pressure test the head itself (apparently it doesn't cost much),
this will find any leaks, into the combustion chamber or out of the
coolant side.

The advice is that chev heads would be so cheap there, just get another
set ex a wrecking yard from a car (run on antifreeze & rust inhib
coolant= good) have the valves serviced, if required & you'll be out
sooner & cheaper.

It's because his mob are loosing the election, he got like this last
time when it became clear Gore was done like a dinner.

Just imagine his fear:-); union thugs like him won't get the unelected,
undeclared power they so desperately need to save them from the
investigations that will confirm & uncover them as corrupt lying
thieves. How was it Harry's union appropriated many millions of real
workers' money & gee nobody noticed??? Makes you wonder exactly what was
Billy boy concentrating on .........certainly not his union mates
running amok nor national security it seems:-)

Even they know as do we all that this term W will fix up the real
reason US manufacturing keeps going backwards..... the union organisers
putting the fix in every time any US Co gets to a competitively viable size.

Honestly does Harry think the US populous is as stupid as him? no way;
when the day comes will they vote in another shallow, lying, cowardly,
run with the pack, anti war banner waver? not a chance!! & we all sleep
better knowing it.

Oh well expect more of the same from the uneducated simpleton union liar

jherring offers:

-Thanks for the tips, Karen. I'll know more Monday when we (the mechanic and
I)fire it up to see what happens.-

Bilge-Say, chum, I'm down in Newport News, let me know before you push the
button so I can put my earplugs in g.

Actually, I'm following the technical part of the thread.

G'luck.

jherring asks:

-How's the fishing down in Newport News? I keep hearing all these stories
about
the CBBT, but I have yet to get with someone and try it out. It's too far for
me to run (from Deale) even if the fishing were guaranteed!-


Bilge- I drove the family over the CBBT two Saturdays ago, and there were a lot
of small craft of every size bobbing by the islands..."Hazards to
Navigation",the deck gang calls 'em.

We're tied up next to Monitor-Merrimac, at the old CSX piers, the cook and the
steward have been doing okay from our stern, but I'll pass on James River
Kepone Sashimi, thanks all the same.

If you're out of the "Budget Yacht Capital of the Chesapeake", you're prolly
familiar with the Bay Bridge and the wrecks, yes?

If it's not too long a run for you, you might try up the Potomac at the
Steuart Petroleum pier...there is, this is no ****, a sunken U-boat in the 80
foot hole just downstream of it.

And I know from experience how strong the tide runs out of the St. George
Island inlet...lotsa shoal water...lotsa "flushage". My union school is the one
with the Hagglund crane growing beside it. Feel free to cast to the pilings,
the school isn't all that fond of it's dockage.


-I was up there today, stuck my finger in the exhaust port, and it came out
wet.But, there was also a buildup of rust between the numbers 4 and 6 cylinder
exhaust ports. (Is 'port' the right word?) Now I'm wondering if the gasket
between the head and the exhaust manifold was leaking. That would be an easy
fix, and not cost much.-jherring


Bilge- I'm thinking "gasket", but not exhaust...if it's wet...head gasket.
Usually, it blows into the oil passages and turns your motor oil into "pourable
gray yogurt" emulsion, but sometimes, it farts into the combustion chamber and
back...happened to my '90 Cougar V-6...made white smoke like a WW2 destroyer,
lemme tellya...damn shame, except for the engine and the transmission, that was
a nice car.g.


-Yeah! Imagine four straight pipe Harley's sitting on your boat.-jherring


Bilge- I don't have to imagine...we have a 7 cylinder Sulzer slow-speed down
below, and 5 Daihatsu diesel gensets...oh, and a Caterpillar emergency
generator, (but it only comes on when you're asleep).

Cheers;

jherring muses:

-Not sure what you mean by 'budget yacht capitol' unless it's annapolis. I'm
out of a little place called Deale. South of annapolis, north of Solomon's
Island.-

Bilge- I know the area, I'm from DC, I have a bro-in-law who lives off of "DWI
Memorial Highway"
(aka MD Rt. 4), and my union skule is at Penis...uhh, Piney Point. Best bar in
Lexington Park used to be "the Roost"...kinda like "Pancho's" from the movie
"The Right Stuff"...only Navy.
At least it was a nice dark joint with a fireplace where you could poison your
liver in peace like a gentleman.
Can't stand "meat rack/amateur hour" joints..."Tiki Bar" in Solomons comes to
mind, as does the "Night Life/Cadillac Jack's" in Great Mills...gaaahhh!
Hoisting brews with the trailer park set...not at all conducive to quiet
contemplation.

The inns get worse the closer you get to Piney Point. The "Old Country Inn" is
the bottom of the barrel...too full of drunken seamen. I almost shot one guy in
the parking lot there once, and a few years later sent another to the hospital
from hitting him in the head before I'd dropped my bottle of Heineken, in my
experience, Pacific Islanders should not drink...they have the tolerance for
hooch that American Indians do.

I have an erstwhile shipmate who keeps his boat at Deale, and that's the
monniker he uses for the place.
