cracked cylinder sleeve

[unhappy porsche owner]

My 2003 C4 cab with 13,000 miles (dealer serviced) has recently been diagnosed with a cracked cylinder sleeve. Has anyone else experienced this peculiar problem?

This was a known problem in the arlier 996's. Haven't heard of it much in later years. You might find interesting reading at the attached link:

This covers alot of years of Porsches, but has alot of info on the M96 engine. a big part of the problem is the "open deck" technology used in the M96/M97 engines. The new 997.2 engines now have closed deck technology and eliminated the IMS.

Also checf out LN Engineering and Flat Six Innovations. AThey work together on resleeving engines. and AutoFarm in England does them.

Is the car still warranted? If so it should be covered. If not the fact that it was dealer serviced may help some, although with Porsche's current financial problems some say they are trying to avoid any warranty claims.

Good Luck.
