Yikes!!! 305E V6 knocking like crazy!

[TJ's GMC]

Yeah, When I pulled one of the plugs I took a look at the piston with a flash light and I can see carbon...so I think I'm gonna try the water deal or just give then a good scrubbing when I pull the heads.

Wow! This is EXACTLY the same thing that happened to "Happy Truck". Changed plugs before leaving WY, got to Canton SD, parked for the day at a car show, hopped in and it started happening.
A local mechanic told me it'd spun a main bearing and it's sat for 4 years.

I have hope!! WOOHOO!

I watched your youtube vid and it sounds EXACTLY the same.

Maybe I won't have to rebuild/replace it!

Not to spoil your bubble...but I wouldn't count on it being some crap that fell in the piston....You say you changed the plugs before you left...then when you arrived to SD you let it sit for a few hours...fire it up and it starts knocking? Its possible a piece of carbon...but do be careful. It could have spun a bearing. Mine started knocking RIGHT after I changed the plugs which indicated some crap falling into the cylinder. But if yours happened several miles later it could be worse. Sorry to sound grim...just don't get your hopes up to high. lol

I'm more excited about the prospect of the possibility. The way my luck runs it'll be a rebuild. Which is actually what I'm expecting will need to happen.

Sadly, I'll be selling this truck. It's a trade off: Do I make it a running truck to get more for it? KNOWING what will probably happen is whoever buys it will probably drop a 350 in it OR leave it as is, get less overall but not have to do the work.

It's all original except for the paint and the interior... and the wood bed. So it's prime to restore to original, or street rod it. 1/2 dozen of one and 6 of another. :/

I'd find someone who will leave it as is. More than likely the truck will be left alone if its running good. I hate it when I go to so many forums and 95% of the people there has 350's. Its so stupid anymore than I don't even go to car shows cause they all have the same dang engine. People criticize me for hopping up my 292 in my 66 chevy and I criticize them for being a cheap #%&@ and being like everyone else. But that's the way it is and I can't change that so I'm gonna do what I want to do with my projects and enjoy being different.

Nothing wrong with hopping your 292, you've got something that's different from everyone else and you're having fun with it. The 350 thing is so overdone and like I say it's a major national obsession!

I hear ya...Nothing wrong with a 350 but too many people think its the ONLY way to go. It took me 2 1/2 years to save up enough to get my 292 done the way I wanted to. People always tell me "Well I'm doing a Budget build" Well, so am I as a matter of fact. lol And I don't use it as an excuse I use it as "Ok, it may take longer, but who cares. May as well do it how I want it done the 1st time." If the 6 cylinders were as popular as the 350 parts would be just as cheap if not cheaper. lol Which would be really nice! Seeing as how I want to do a turbo build on another 6 cylinder.

Nuttin' wrong with the treefiddy, but I agree: over done.

I myself wouldn't leave Happy Truck original. Tech is so much more advanced now. I'd upgrade his suspension to tubular a-arms coil over shocks, and sway bars front and rear with disc brakes up front.

Drivetrain: I've a '65 OLDS 98 out back with a 455 ROCKET. a valve grind, some head work (with porting) a mild cam, and a street demon carb, 3-speed auto and posi-traction rear end. WOOHOOO!!! Look at all dem tickets!!! ;D

I'm all for all stock, but this truck is custom paint and interior. Full stock it ain't.

If thing go just right between now and October I've an eye on a '66 Buick GS. That'll be restored. The '66 'Lark I've got now I want to make a "pro-cruzer" as opposed to pro-touring. Who can afford the gas for that? Not me, not most the people I know.
