Saab 9-5 Head Gasket Leakage
Saab 9-5 Problem
Engine Affected: 2.3L 4 Cylinder Turbo
Average Mileage: 90,000 mi (60,000 mi - 120,000 mi)
Visitor, 2009 Saab 9-5, 60,000 mi
Started leaking about 55K - slow oil leak onto the block and then down adj to the oil filter;
took it to a shop thinking it was a minor fitting or tube, and they told me it was a head gasket
( $2500-3000 ouch !!!!!! ) This is ridiculous for a > $40K car that has been well maintained.
There is nobody to complain to, since SAAB is now defunct and the remains owned by a Chinese company.
Called the SAAB dealer about an extended warranty or service bulletins that might cover this, and they
just laughed at me.
Would oil stop leak work, or will that destroy the rest of the engine, turbo, etc ?
How involved is re-torquing the Head Bolts ?
