What do you think about my HEAD ???

the repair looks pretty good, but who knows how it will survive? I would really question the place who did the work. How confident are they in what they've given you? Are they willing to back-up their work?

Welcome to the forum by the way, nice to have you.
 
I threw out a head that had a crack like that. Around here, they are so common that it is cheaper to find a replacement than to fix one.

If the weld is properly done, it will be OK. Flame-surface welding is a proven technique. Perhaps your machine shop can magnaflux the head and give an opinion.

It'll be a good head until it fails. :x :lol:
When it does and you need a new one, you can replace it with a Classic Inlines aluminum one!
:banana:
 
I think it will do OK. The magnaflux method for crack testing would be one way to confirm integrity of this repair.

Did you buy from Ebay, or a member of this Forum?

Thank you for your replies !
A french salesman bring me the head many years ago as I wanted to run on unleaded gas, my car ran so good so I didn't put it on the engine and didn't see the repair... :oops:

I was wrong, the head seems to be a 80' (cast : E0BE-6090-BB). I made some other photos, there is tags on two freeze plugs :

It is writen ".M C H. VOID IF REMOVED", Void if removed, I see what it means, but "M C H", I don't know... :?:

I have another question : what is the magnaflux method for crack testing ? and I don't even know what is a jughead?? A man with a faucet behind the head :wink: ?

C'est comme d'avoir une idée fixe, qui n'est pas un chien Gallois apellé Idéfix.

Guillaum has cars named Betty and Veronica, the two girls in the Archie comic series. The comic foil was Jughead, which means something like 'numb skull'.

I'll leave the technical part to my more knowledgeable associates.
 
The little tags are for preserving warranty of the rebuilder (possibly expired many years ago). If your head overheats greatly, they fall apart.

Here is a simple description about how Magnafluxing is used to check for damage.

Hullo every body,
I have seen this type of repair many times. It is an expensive repair and usually done on expensive or difficult to repalce cast iron assemblies.
This has had a substantial crack. Like "dur einstein!".
What has been done used to be reffered to as "stitch" repair.
Background is,
The crack would be assessed and the ends of the crack determined.
First a hole is drilled at the start of the crack, through to the corresponding water jacket.
The hole is threaded and a plug of slightly larger or taper, threaded into the hole and bottomed out. The plug was then nicked with a chisel and broken off in the hole.
This was carried out all along the crack. With an extra one at each end.
Once completed, a grinder was used to smooth over the area of repair.
This is a great system because as you can imagine the stresses that caused the crack in the first place are nuetralized or minimalized.
This type of repair will outlast the original casting.

+1.

I had forgotten the process to making that sort of repair so I didn't bother posting - but this reminded me of it. I wouldn't worry about it.
 
Famous last words, "I don't think she'll blow!" :P .

Looks like its well done. Go for it! As long as it doesn't say Renault on it anywhere you should be OK. :thumbup:

But keep your eye open for a spare you can get cheap. If you find one, then work that one up to the tri power. Keep watching that one well known on line auction site! There is a lot of work needed to do the conversion and it would be a shame if you invested all that time and money only to have the repair job fail. IMHO.

Cool guys !
"Go for it! As long as it doesn't say Renault on it anywhere you should be OK." >>> You're so right!!! But thanks to my first car which was a renault, I learned mechanic... And now my daily driver is a 84' 300SD Mercedes :wink: !
