Subject: Re: 4.5 litre engine problems and upgrades
Sorry to hear of your grief and kudos for posting the info here. Sounds to me like someone miscalculated the required piston clearances. Distortion from head studs can be negated if the block is bored with a torque plate in place. Probably no one does this. What about extra cooling with a larger rad capacity auxiliary electric fan and better water pump? Thanks for the warnings! I wonder how much heavier is your sedan than my T7 bodied M45? Summers are getting hotter even here in Canada so this is valuable info.
