Well the truth is almost every automotive diesel has an aluminum cylinder head. Thats not completely true there is the Peugot, and a few others. I have seen more cracked GM diesel cast iron heads and IH (Ford Diesel) than all VW heads together. Don't get me wrong I think cast iron will take more abuse than (overheating)than aluminum before <img src="/forums/images/graemlins/barf.gif" alt="" />ing. Yet GM and Ford's new automotive diesels Duramax and 6 liter both have aluminum cylinder heads, because nothing disapates heat quicker, but more importantly weights less. My experience with diesels that overheat is the same as with gas engines that overheat, <img src="/forums/images/graemlins/shame.gif" alt="" /> NEGLECT. <img src="/forums/images/graemlins/shame.gif" alt="" /> Diesel engines are usually very economical and most owners often forget to even add fuel let alone flush their cooling systems. <img src="/forums/images/graemlins/ignore.gif" alt="" /> Plain and simple diesel engines go longer with less maintance but when it needs repair you better hope you kept all those dollars you were saving at the pump. <img src="/forums/images/graemlins/shiner.gif" alt="" />

Would I put another 2.3TD or 2.5TD in a Raider/Montero YES.
Are there an abundance of 2.3 TD out there NO.

Well at least not in my neck of the woods, the ones that are still around the guy is about 60-70 years old and when you ask him if he wants to sell it he just smiles <img src="/forums/images/graemlins/notooth.gif" alt="" /> and says "Why would I do a stupid thing like that".
Don't give up they are out there if you are willing to travel or I guess PAY... <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />
