Why I was so slow at the Shootout….LOOK!!
 

Today we pulled the plugs, just for fun, Everything seemed fine back in August when I last checked them…Look at the pic, that’s strait from cylinder #3. It is the only one like that, They all seem rich, I figure that that’s from the fogging oil…. The rest of that plug is probably still in the cylinder, so what should we do? How would this have happened in a bone stock 4.3l V6?

Thanks,
Tommy

Through my amateur photo skills, I forgot the pic!!

Ouch that sucks bad :(

Looks to me like u should stop getting your gas from the ten foot garden hose ,,,,,,,,, and start buying CAM II

Crank it over with the plugs out, the coil wire off (or it you have a kill lanyard, yank it instead of pulling the coil wire), and the throttle wide open. This will blow any "large" chunks out the plug hole (I doubt there are any, but it's best to give it a try). Then put in new plugs and start him up. Let it warm up then run a compression check to determine the condition of the rest of the cylinder. You may be just fine.

Stop biting your nails.

Tommy - quit chewing those nails too!:p :p

And.....
 

wear rubber gloves, you should know the ladies don't like grease under the finger nails.

Go to the auto store and get one of those magnets on the end of a telescoping rod, the magnet pivots on the end of the rod. It will fit right in there and then you can move it around. I'm assuming the tip of the plug is of metal containing iron so as to stick to the magnet...... Try that first before turning it over.... I have one of these magnet rods in my garage... 2 bucks... When you think it's out, definitely do a compression check on that cylinder.....

You more than likely burnt the electrode off -- That means it turned into vapor and went out the exhaust. I wouldn't worry too much about it.

My advice to you...
 

Quit using those cheap assed Champion spark plugs !!!

This is the best advice so far!

Try the magnet, then kill the ignition and turn the motor over just to make sure its gone, finally do a compression test. Clean those grimy paws!!!!!!!!!!!!!!!!!!

You probably found that plug somewhere and are trying to convince dad that the engine is bad and you need that upgrade you've been begging for. Not a bad plan!!!

Hyper, are you a bundle of nerves or what? Easy on the nails!!:D ;)

Is this the first time you ran the boat after the winter?? I mention this because you talked about fogging fluid. I always change plugs for the new season. I first start the motor on the old plugs to get all the fog out, then put a fresh set in.

Not that that's what caused the problem. I would think it was poor fuel. Is this last years fuel you are running? I will usually cyphon it out and put it in the truck or something. if not i will baby the boat until all the bad fuel is out. I had a plug that looked the same a couple years ago. Ended up being a bad batch of gas that i bought. It never hurt the motor....must of blew out the exhuast...but i did change the oil just to make sure.

They are the platinum ones....

I always bite my nails....

Boat hasnt been run this year yet....When we winterized, we fogged it, so that is why it looks so rich (at least I think so?) They were put in there mid August, most likely less than 50 hours.

LOSE THE CHAMPION PLUGS !!!!!!!!

Don't bite your nails. Some ladies like it when you gently use them on their ni.... :D


My guess is that the plug is way too hot and that you vaporized it.

I have been sexually frustrated all my life then. New pickup line: I have been told that biting my nails is a sign of being sexually frustrated...Could you help me break the habit?

The truth finally comes out!!:D :eek:

I think your just chewing your nails out of boredom waiting to get on plain.(jk):D

What Tinkerboater and Gordo said.

Make sure you run the correct heat range plug for your motor.

Check the compression. Hopefully you don't have a detonation problem.

Are you sure you didn't run out of fingernails and start
chomping on the plug

Do you guys think that all of those 4-5 mile WOT trips finally caught up with it?

No wonder you are sexually frustrated if my my hands looked like that my cock would never let me touch it either.

:D :D :D This stuff is the best after a $hitty day at work!!!

Good one Lapse of Reason, I'm LMFAO !!!! :D:D:D:D

always use new plugs after fogging oil. not only does it glaze the plugs it can effect the heat range. an earlier post said it correctly. run the engine on the old plugs to burn off the fogging oil. due a summerization tune up,ect. take it easy on the old fuel. there are different fuels for winter and summer and around here we start getting into winter fuel in October,so keep that in mind as well. make sure to wash your flame arrestor. fuel filters should be changed after you run it for the first time in the spring, the reason to do it now rather than in the fall is because all the sediment,water and debris will migrate to the bottom of the tank. the boat sit's still all winter so it is like vacuuming the bottom of you tank and replacing the bag.

i have also seen that condition i a 4.3 before. this one was a 1988 model,middle cylinder port side. checked out ok and still running today.

get rid of the champion plugs, ngk v-grooves are good.

enjoy

5 mile WOT runs should be no big deal on a stock motor running in the recommended rpm range, assuming clean oil and proper state of tune (and fresh gasoline). I had a Wellcraft with a stock 260 Mercruiser and we put 700 hours on it, probably a full third of it WOT. It was not unusual at all to run 4600 rpm for over an hour at a time. The boat was parked under a gutter and was accidentally "sunk" and after that, the rings didn't seal well and there was excessive blowby so I pulled her down for a look-see. Cylinder bore had a noticeable ring ridge at the top of the stroke, but was otherwise in good shape (except for the rusty rings). Rings, bearings, a pass with the ridge reamer, and a few strokes of the hone and it was still going strong at 1100 hours when I sold her (she got a Comp 268H cam, a set of cheap springs, and some hand-lapping on the valves, too, while down).

As far as plug brand and style, I'm not a huge proponent of any particular plug on a stocker - whatever the parts house hands you will work okay as long as it is a direct crossover for the Merc recommendation..
