Porous casing/cylinder heads fix

[busboy1303]

Thought I'd post some info on this as I've used these guys a couple of times with great results.
When my van was stood over the winter I used to find small droplets of coolant forming on top of the cylinder heads. You could actually see where the coolant was seeping through the aluminium. Anyhow, whilst I had it stripped down a couple of years ago I sent the casing and both heads off to this place. They came back after a couple of days and they've been fine ever since.
Obviously this is only relavent to people in the uk, but I'm sure other places do this type of treatment elsewhere.
Thought this might be useful to somebody.

interesting!

Very,

How was it cost wise?...

[busboy1303]

Quite reasonable I thought, versus the cost of a replacement head/case. About £100 I think for the whole lot.

Very interesting. Might look into getting this done to my heads once I figure which ones are the best of what I have and am I'm going to use

yeah looks real promising. absolutely worth it if you put alot of time and money into your heads for porting and so on. just for that extra security
