That is what I had done :( Boring relieves the tension on the liners so they will slip after a few km, once the block gets hot.Quote:

The RAVE description of the pre and post MY99 production models of the 4.6 concurs with the above.
Quote from RAVE:
"The cylinder block is fitted with cast iron cylinder liners which are shrink-fitted and locate on stops in the block."
I haven't pulled mine apart yet to check:)
I do remember on my P6's 3500 that there was a stop at the bottom of the block - the re-conditioner called me in to look at it, because I had asked him if he knew about the slipping liner problem.
Together we agreed that we couldn't see how the liners could move, when they were clamped at the top by the gasket and to my lasting regret we got it wrong.
Now I know that the top-hat relies on the head to clamp it in place rather than the gasket. The liners not being pushed all the way down, makes sense as well,

here is a PDF i found on here some time ago about the process of pinning liners, i didn't write this but found it interesting.
correct, besides i'm not after a race car or stump puller, just something with enough torque to pull the skin off a rice pudding :)

actually same cost as replacing the 4.0 with a 4.6.
I have 2 complete 3.5's here I got for nothing so ill probably just stick with the best one of those unless I can find a 3.9 to do instead
