Citroen XM Forum

I thought the seller name looked familiar.
Im not sure it was the 16v directly that suffered piston slap, i think this 16v engine had the cast iron XU block with a 16v head fitted although there are other changes obviously.
The XU10 petrol engine suffered piston slap in the early years of XM production from what i remember but wasn't aware the later 16v suffered.

Yep. known problem. All that efficiency comes at a price, light mass and low friction = high wear and lack of piston control.

Probably best stick with the diesels and PRV V6 then!! Regards, Matthew T.

Are you a convert now, Matthew?

Not quite Will, although I was quite impressed by the experience of driving Ray's car! I think the early V6 is unequaled for character and performance and for me remains the ultimate XM power plant! With regards, Matthew T.

I believe (again could be wrong) that the engines were modified to cure the problem but there was no recall and affected engines were dealt with on a case by case basis.

Are you back now Matthew?

Yes Dean I am back in the UK and almost home after the apartment around 9.30am local time! With regards, Matthew T.

I seem to recall that early on the PRV V6 pistons were also modified by an increase in length.

Alloy wheels from this car now offered on ebay.

And the lucky purchaser has to leave their old wheels behind! Regards, Matthew T.
