I got a question- how much of your shop tools are you going to have to pawn this time to pay restitution & court costs for your latest plaintiff?

So consensus is that regardless I need to do a rebuild. I've done nearly everything else in my body off restoration (see thread in signature). Any reason I shouldn't attempt a rebuild by the Tom Wilson book myself?

Nope, not necessarily.
But JohnnyPants seems to want to have his way (as usual) so some of us just gave up. Crying or Very sad


See,,you're still a fuckin snapperhead..just because the hammer fairy got chased away from your Hudson Hornet when you dumped a case and a half of "Wynns Motor Honey" in the crankcase doesn't mean its sound advice for every engine noise..

markiemark9, you just have to see where things take you. and in regards to johnnypan, you've just got to learn how to read when he is busy busting balls and when he is being helpful. Just measure and clean, and the rest is the journey. Oh and have fun when doing it Razz

I'd still like to know where you come up with this stuff. If you can weed through the bull shit, johnny does have some good advise.

So here's what I found. Pulled the plug and stuck a magnet down there and pulled up this foreign matter (penny included for relative size):

Any idea what this could be? Part of a ring? Something out of the carb?

Probably ring-----which might explain the oil on the plug situation.
In any event, it blows my "carbon" theory all to pieces. Embarassed

I wondered where that penny went Laughing ..well thats actually a good sign,perhaps all you'll need to do is a top end..and rod bearings..you'll find you need heads as well,given that hunk of steel was hammering the combustion chamber as well as the plug..thats predicated on your being a perfectionist,alot of folks just fish the crap out and if it runs ok let it go..

Forgive my ignorance but can rod bearings be done without splitting the case? I'm a total engine newbie (beside the basics of timing, valve adjustments, and other tuning elements). Shocked

Shocked Confused Sad

DO you still have this tube in your carb?

Apparently, yes, although as millions of others on here will attest to, I didn't try it...

I don't understand how there appears to damage around the ring of the plug, yet the electrode is intact. All I am certain of is that the piston could not have done it. And if the knocking sound was from the piston hitting the plug, it would it not eventually stop when it had pounded the electrode out of the way or made a pit in the piston? I would also think it would vary with temperature, as components expanded as they got warm.

yes you can..remove heads,cylinders and pistons..then you can get at the rod cap by running the rod to the bottom of its stroke.

It can be done. BUT it is fruitless to go through all the trouble with rods and bearings that will give you proper clearences. I hope you plan on AT MINIMUM plastigauging all the rods and bearings on the journals they'll be living on.

EDIT: JP beat me to it, but make sure you check your rod (bump up) orientation as well as cap end numbers matching the same direction as the big part of the rod. Since you can't see them installed, it's extra-important to pay attention to what you're doing.

Not sure you could doing anything about the journals that way though. I would at least want to polish them.

And if you've gone that far... geez ... split the dam case.

I offered to let him do it for free, to show he cared, things went south from there

To the OP- yes you can do all this yourself. Be aware though, that folks on here take for granted that you have all the necessary TOOLS to properly balance, measure, and check clearances on everything, they don't think about things like this. I am not saying don't try it (I wish I had now) but you WILL need to invest in more tools and parts than what you currently have at your disposal, which no one is telling you--of course if you are planning on routinely fixing up old aircooled engines it's not a bad investment.

See?

It ain't that simple, except to folks who have done it for years and have all the tools lying around.

I agree,but when doing just a top end you should do rod bearings... find a scored journal or an bearing worn to copper you have a definite reason to split the case..if not,and everything looks good you have the confidence that the rod bearings are new..
