hi guys, i have a 96 4.5L 80 series, starting to see small amount of creamy stuff under my rad cap, done an oil change, no sign of coolant in the oil, no overheating or loss of power so far, actually its behaving even better after the terraclean i had few months ago, better power and better MPG believe it or not, with power mode on i get an average of 14.5mpg, compare to around 11 before the terraclean, its got the old school single point LPG conversion, anywhere or any mechanic would you guys recommend around hampshire area if she has to get a HG or even the head done eventually? and what sort of money we talking if you have such job done recently?
