Can this head be saved

This is one I broke a while back, and I've been hanging on to it to rebuild. After reading the other thread regarding the same issue, I'm now questioning whether this is worth keeping. The dings are pretty good, can they be smoothed and be fine?




If it's not worth it, I'm pitching it. /ubbthreads/images/graemlins/dunno.gif

cool. I really hated the thought of throwing it out just for that, but I've never had any machine work done so I didn't know.

usually they just weld aluminum into the head and grind down to the correct shape. Its fixable if the machine shop knows what they are doing and cant weld aluminum correctly

Well, when I get to the point I'm ready to have it rebuilt, I'll pay to ship it to someone good if need be. That'll be a while though. I'm just cleaning the garage and getting rid of what I can't use.

Give Chris aka Boostin Hard a yell when its time. His machine shop has the skills needed but definitely want to magnaflux and pressure check for small cracks that can end up being a heated water injection system. /ubbthreads/images/graemlins/grin.gif

Usually they'll use a regular liquid dye penetrant on aluminum instead. Basically a thin liquid dye that wicks into any cracks, highlighting them after the excess is wiped off. Sometimes for stuff like this, they'll use a clear UV sensitive "dye-pen" (or DPI), The advantage is that in a dark room under blacklight, cracks show up as glowing lines, plus you don't end up with permanent red stains on the part in question, especially if it's cast.

Magnaflux is essentially the same thing, colored or UV, except that by applying a magnet on magnetic materials like steel or iron, the dye concentrates at areas with cracks, so it's a more reliable test. Magnaflux can also be done with dry powders instead of a liquid dye.

No need to ship. Bring it to Nolan's like I've mentioned before. They are downtown and do quick/CHEAP work.

I believe this is the other one that you were referring to. Any thoughts on being able to save this one?

Eh, would cost more to fix than to buy another head.
Unless you got some good port work and/or oversized valves find a good core for $50 plus shipping all day.

Not saying it can't be fixed but thats alot of welding and machining that some shops may not want to touch, If it was a ported head I would fix it but being that you need guides and seats on the one cylinder at least I'd see if I could find a junkyard head thats good and rework it. It would just bother me that it looked that bad and I'd be constantly wondering if it had a crack in a water jacket etc.
 

That was my assumption all along. Thought I'd post it up for fun though.

If you think that head looks bad you should see the piston. /ubbthreads/images/graemlins/frown.gif
