how strong are the 4.6 thor engines?

Indy once told me a slipped liner presents just like a failed head gasket - my engine is a little "tappy" and uses a little coolant but the needle stays very firmly at 12 oclock and I have done two or three block tests over the years which have been negative.

Seriously think very carefully about stripping anything. Cracked block is the classic issue usually on the back 2 cylinders after overheating. Symptoms? Initially minor coolant loss the same as every other v8 issue! These run hot when there fine. Live with it for a while poke at it and fiddle. £1600 for a short motor plus £500 for hg plus x plus y. Plus 50 hours graft etc etc. Huge commitment on a £600 vehicle. Limit your spend in other words don't become trapped!
