Crossflow heads crack alot?

[Anonymous]

You guys all know the story on the first crossflow head I got that was cracked in 6 places...

Well the new head has issues too. It has at least 1 crack near the front plug. The shop says that they can fix this though. They are also real concerned about the amount of corrosion on the water passages. He wants to build a couple back up by adding new metal and then seal all the passages.

Sound normal or do I just have crappy luck???

It's a 20-year old piece of metal from a car that was never intended to be collectible. Yes, some defects are reasonably expected. Major cracking - no, but corrosion in some spots for sure.

Don't worry about "luck". The minute you depend on it, it'll bite you on the rump!

its very common for them to crack between valve seats.. but other than that there usually good.. Even when they crack between the valves most times there left alone as the crack doesnt cause any problems there

Don't wory Spyke, the Honda casting is just brilliant. Anything that cracks can be welded with ease.

I wish I took photos of my wifes first forray in aluminum frying. After practically burning the exhast port to number five, undercutting the seat and melting the chamber, a quick reweld, and it was all working again.

The heads rust is becasue of the silly antipodeans who never followed Fords request to use a proper anti freeze with corrosion inhibitor. Everyone toped there too small cross-flow radiator up with tap water, and thats where the scale formed. There is a bleed valve in the upper radiator hose, Ford did all its homework here, but silly Igggeeeets fail to ever read owners manuals, or the big black stickers Ford emblazoned on every alloy head radiator.

Mutraic acid, used with all the Safety precautations, can removethe scale with ease.

Out of all the crossflow heads I've seen stripped down, I've only ever seen corrosion on them. Its the OHC heads that are prone to cracking, along the cam gallery between cylinders 3 and 4, and the bit between the ports on the inner cylinders. As well as the corrosion problems on top of it all..
