Re: Would Anybody Attempt To Fix This?
I can't believe this is a serious question!

Replace/ If you can't find the parts...get another engine! I can't believe that you can't find a replacement? Is it a flathead? Search for original parts if you have to. I knew a guy with a 1933 packard and searched for 2 years for a part! Last edited by FrankWest; 12-26-2015 at 06:36 PM. |

"--Quote (Originally by FrankWest)---
Even if you could weld/repair..fill the holes..How do you know they will stand up under the heat, pressure, explosions of the internal combustion Engine!" Frank, don't give welding a bad name. Pistons, connecting rods, crankshafts and wrist pins have been welded, remachined and run for years in street applications. One of the fastest unlimited hydroplanes in vintage history ran pistons with welded domes in one of it's first races. That was an Allison aircraft engine with 80 lb of boost pressure. There is still a stock model A engine out there running that has a crankshaft that was broken in 2 pieces at the #4 rod lournal. |

Re: Would Anybody Attempt To Fix This?
I just bought two .060 nos ford pistons from Bob Selzam in NJ for 19 bucks apiece. Of course I had to melt the cosmoline and paper off them. Maybe not the same weight as yours but maybe someone has one they'd weigh for you. I have a friend here on the island who drove a '51 dodge six in high school. When he threw a rod, he and his dad pulled the head, dropped the pan and pulled the whole works out of #3. For the last 2 years of school he drove an inline 5. Just sayin....A half ounce outa balance isn't the end of the world. (and Frank couldn't have had much oil pressure after that either)

Re: Would Anybody Attempt To Fix This?
When I was a kid, my dad lost the carb. needle valve in the grass under the car. Guess what the result was when he located another, put it in, and started the truck?

Re: Would Anybody Attempt To Fix This?
WELL THEN...GO FOR IT. Repair the piston head. Look for a shop that specializes in that type of repair, and has a track record of success. You want to make sure that it is done properly. In fact, when you find such a shop they will tell you if your particular piston can reliably be fixed.
Just remember just because you are adding metal to metal it in no way implies that the part will structurally act as it was originally created. Metal is very complicated there are grain structure, work hardening factors, temper, it can be brittle or soft and the junction between the original metal and the PATCH can create large stresses that can cause a malfunction under pressure and temperatures. So any repair must be done with all these in mind. If the repair is done without the considerations mentioned above, as a quick fix it may work, or it may work only for a limited time.

Re: Would Anybody Attempt To Fix This?
I can't believe there is still a discussion on this subject. You can get the exact piston made by Egge, Arias and Mahle, just put it in a box and send it to them and UPS sends you a new one and you are still considering a repair! I have a degree in Welding Technologies and a Class 1 Welding License from the City of New York and have been TIG welding for almost 50 years and I would never attempt this repair. There are too many factors to consider besides just welding the piston. Like I originally said you will get the "we do it all the time" comments but do you really want to "keep your fingers crossed" every time you start your car? If it was a one of a kind part that I couldn't ever find of course I would weld it, but not a piston you can get new.

Re: Would Anybody Attempt To Fix This?
Tony,
WE are only trying to help. After all, You asked the question, Would anybody Attempt to fix this? I, like others, are just trying to answer your question the best we can. we wish you success, not failure. I recommend that you try to find a replacement. After all you are NOT on Gilligan's Island where you have to make due with what you have. Last edited by FrankWest; 12-27-2015 at 04:05 PM. |
