Thanks, John. I'm no expert in this stuff - I know just enough to be dangerous - LOL!

UPDATE - After scraping the carbon off the piston tops and wire brushing them, I didn't find any stampings to indicate over-sized pistons. The number inside the skirt of the broken piston is 1858663, a Chrysler part number. According to my local machine shop, his sources say this is a "high performance" piston, and they want $125 for one. Can anyone verify this? Surely, I should be able to obtain a replacement piston for less than this? All suggestions appreciated, thanks!

Good luck with that HOA! I bought my house specifically because it didn't have one.

R.




I am with you on that.. Looked a many homes ( here in Florida) with bankrupted HOA developments with NOTHING being done for the HOA fees, still a Lawyer is collecting the money..

One of my employees stopped paying his.. Almost lost his home.. Seems as if the Legal Firm was foreclosing in his home without telling him.. VERY SCARY......




Another tip is to Not buy a house with a front facing garage because the community can tell you what your allowed to do in your drive/yard in front of your home. With a drive and garage in back anything goes...at least around here.

You should be able to find a 383 for $125 ... your local guy source is still watching reruns of circus d' sand from 2005 ...

Thanks for the link - Summit has this piston (W366NP) for $46 (it's $74 at Rockauto). Still more than I want to spend. I've just gotten a line on a used piston for $10.

JohnRR - I've been scouring the want ads, but have been unable to locate a running motor in the SoCal area for less than $400-500. I've found a few for less than that, but they are in pieces - which is basically what I'm dealing with right now. Unfortunately, I don't have the luxury of time to let one fall into my lap. I only have two months to get this car running, and vacate this space in my garage.

Don't mess around. You can buy one piston right now on Rockauto for $24.67 plus shipping, with a 5% discount if you're savvy enough to go to retailmenot.com and get the discount code. There's only two left at this price. Buy a ring set while you're at it. Then put the doggone engine back together and get on with the project.

ENOUGH trying to make this problem any more complicated than it is! Find a machine shop to press off the old slug and press on the new one. Won't cost more than a few $$$.

I know all about getting stalled on a project, trying to make it perfect. Don't get caught in that trap!

R.

PS: It's not a high performance piston, it's just a garden-variety piston from a Newport of something.

You realized that missing portion melted/burned away. Had that happen to a 43 that massively overheated. That smeared metal on the rings is melted aluminum.

Odds are very good more than just that piston has issues. I would put a smogger 400 in place of that 383 before I tried to cheaply fix it and only if I absolutely had to have it running to get rid of it.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Thanks, Dogdays, for the virtual slap in the face - I needed that, LOL! You're absolutely right; I'm being penny wise and pound foolish. It's pointless to drive 40 miles to buy a used piston, just to save a few bucks. I'll order one from Rockauto and be time and money ahead.

Supercuda, I'm guessing there may have been an intake manifold leak at the #7 cylinder, which caused that one to run way hot. After cleaning off the other pistons, they really don't look bad at all. And, as noted above, I have been unable to locate a suitable replacement motor, so I'm proceeding with my plan to keep this one. There's not a huge demand for '66 Coronets, and I can't count on selling this car in the next two months. Hence, I need to get it running in the meantime.


Oz, I hear ya! I know I've got my work cut out for me, but I really think I can pull it off. For one thing, I'm not restoring anything to the standards that I would if I were keeping the car. I'm just doing some basic cleanup of parts, and doing the repairs. I also decided today that I can skip doing the power steering pump, brackets, hoses, etc. Same goes for the electrics (except for the ignition circuit). This car doesn't need to be completely road-worthy; I just need to be able to start it, and move it around in my driveway.

I've got a couple power steering pumps and brackets out in the back shed...can't remember if they were small or big block if you did want to get it steering easy too

I've got room on my driveway.. not sure if I am in the mood for a project or not though off hand.

F64, I'm glad you took that the right way.

I SO recognized my own pattern, and realize the pattern is keeping me from finishing easy things that should have been done long ago. I probably never will completely get over this issue, but I'm working on it.
Good Luck!

I'd list it as a non-runner. You will solve this and then find 50 other little things that will bog you down. At that point you'd have been better off finding a whole drivetrain, etc so on and so on. These things just never seem to end.

Have you tried to wrap any logic around that statement?

My bro-in-law, a retired mechanic, is the one who suggested this. He has seen instances of intake manifold leaks causing such things. A leak at the intake runner for #7, where the manifold meets the head, would allow outside air to be pulled into the cylinder, diluting the a/f mixture, thus leaning out that cylinder, and causing it to run hot. Since none of the other pistons show any obvious signs of either abuse or overheating, this sounded like a logical and reasonable explanation for what might have caused this issue. Does this not sound possible to you? He wasn't saying this is definitely the cause. If you ask five people on this board, you may get five different explanations.

What did the gasket look like??

But does it really matter at this point , since you are selling it as a running core anyway ???

If you were close by I would give you a good 383 just to stick it to the HOA, they have NO BUISNESS telling other people what they can or can not do with property they did not pay for! If I had read this two days ago you would be receiving the motor today, a friend just went down there in his truck to get me an nice 02 Durango R/T with a blowed motor


I am not causing global warming, I am just trying to hold off a impending Ice Age!
