Hi all,

I have just joined and was after some advice. I was told be my mechanic that the head is cracked and may require a new head. It's a FG XR6T and has done 69000kms, is this acceptable for a car like this? Any help would be appreciated.

This is the first time that I've heard of a head crack on an FG.

Can you share some more info please....... such as why he thinks it's cracked - where etc..

Proof of cracked head...dont belive it.

Whats the situation? Overheating? Evidence of coolant in the oil? Or did your mechanic just decide its cracked????

69000k's, what year? Warranty?

Started with rough idle then losing coolant, milky looking oil, high compression in cylinder 6. Started running rough a few weeks ago, he tried plugs and coils and eventually ended up with this diagnosis. Car was log book serviced and treated well I thought.

Engine gurus.......

Would it more likely be gasket than head?

Cant recall ever hearing of a cylinder developing higher compression? How would that even happen?? The chamber would need to get smaller somehow?

Normal noise, I know the noise exactly and my fiance describes it as a police siren also. I am yet to work out what it is exactly. Remember these engines are producing max torque from 2500rpm so there is a fair bit of air flow happening at lower rpm. I have changed the intake muffler to a delete kit and the stock air box to a herrod intake and the noise is still there. I am assuming it is somethig to do with the design of the plastic crossover pipe. Happened in my car since I bought it new. It is a lot more noticable for the first few k's I drive even though I warm it up before leaving.
