Hi all

greetings from Madrid Spain. I have the opportunity to buy a Spanish register Hummer H1, 1994 with 6.5L engine NA.
At least 8-10yrs sitting at same place
Odometer is showing 17k miles.
no smoke
truck gets overheated apparently, after a while small column of white smoke comes out from the top of the engine.

i do have some experience with this engines, and I see this engine a bit knocking or kind of “metallic sound””

I have some videos on YouTube as follows

could you pls show me your view?

thanks

 

White small smoke column


any help or any personal view will be appreciated
