Hold your water

I have a small crack in one of the grooves on top of the expansion tank. It's only about 1/16th of an inch and hairline wide. I tried to drop a blob of solder on it and it worked for a while but eventually started to weep.

Any suggestions for plugging this permenantly? The metal is still very solid around this crack. It's not crumbly and rusted.

Thank you, just needed a kick in the brain.

Duh

 

Here's the fix. Brazed, smoothed and painted. Like new. Also, I found the bottom of a radiator cap floating around inside the expansion tank.

Yeah, it looked good until I put it back in and it sprung another pinhole leak.

I took it to a buddy's shop and asked if I could just use his oxy/acetylene torch. He said he would do it for me. He always wants to tell people that he works on Ferrari's and this is his way of proving it. I stood there and watched. I wasn't impressed with his work and almost said, "Hey, it looks like there's a hole in that" but I didn't. Now I'm going to do it myself. Just need to get some gas for my torch. Another wasted effort that has to be done over. Friggin' love this B!TCH

You'd think I'd have learned my lesson years ago. If I EVER mention getting another party involved, just scream these words at me:

STOP LETTING OTHER PEOPLE WORK ON OR DRIVE YOUR CAR! THEY ONLY MAKE IT WORSE! NOBODY KNOWS OR LOVES YOUR CAR MORE THAN YOU DO!

 

OK Romano. I'm counting on you to be my support. Kind of like an AA member. You have to talk me down when I start acting all crazy n stuff turning back to my bad ways an associating with my old gangsta mechanic thugs.

 

How cheap wasn't it?

 

So I'm learning. This is just another of the many "bad design's" in this car. As beautiful as she is, she is just a Frankenstein of bad parts. I swear Ferrari went to every supplier and said "Give us the worst of your best and we'll show you how to polish a turd to an ultra high gloss"

I dumped a good 1/3 cup of rust chips out of that tank while I had it off so I'm sure I'm just playing games waiting for the next leak to spring.

 

I saw the stuff in the store when I went to get the brazing rods. You can use MAPP gas on both the silver and brass as far as I know. The problem I've heard with silver is it's very picky about what it sticks to. It must be super sterile clean. Brass is a bit more forgiving. I don't know if that's true. I've only worked with brass. But hey, I got it to seal. I can just keep playing little dutch boy for a while and keep plugging up the holes. Let's see how long this one holds.

 

TOTAL DICKS!!!!

 

Holy crap! I just looked at the exchange rate. Yesterday it was about $2=1 pound. Now it's $0.75=1 pound.

Please don't raise your prices. Let us have this one guys.
