Well the new engine has only got just over 1000kms on it and seems to have a horribly similar noise to the first one, which is a lifter racket which is worst between 2000 and 3000 rpm. Which, could be either this engine has a similar problem to the last one or the noise is coming from somewhere else.
I have thought about the exhaust being the problem but I don't think it is a leak because a) the exhaust has been fitted twice and b) the noise doesn't vary at all whether under power or trailing throttle.
I think I had once heard mention that certain headers can make noises because of pulses or some such thing. If this is what you mean let me know, however this would not be the case for your monster as you have a full Herrod exhaust , yes?
Anyway, I have learned to live with the noise, thanks to the fine stereo system always being above a certain volume, which is a good old technique I have used to repair things on my old XY's etc
Apart from that the ute is an absolute joy, and I love every bit of it (exept maybe that god damn Ford paint, it marks sooo easily and I do get upset)
Thought it was time to try a turbo for a change :)
