bad head gasket - �and head specs

We took the head off a car yesterday -
A running car - no water in the oil - !!!!
and this is what the head gasket looked like -





This is what it SHOULD look like

--------------------------------------------------------
and this is how to tell you if your head is within factory specs

ok
see the upside down " L " looking thing here ?
this is to tell you how much ware your head has - and if its serviceable -

the distance between the surface of the head and the flat part of the " L "
should be as follows

for all 924 s - and 8 valve 944 from 82 to 89
new - 24.00 mm +- 0.1
worn -23.8 mm

for all Turbo's m44.51 and m44.52
new - 24.00 +- 0.1
worn - 23.6

if you head measures 23.6 and / or below that then you WILL need to use the thicker head gasket as shown here -

for all the twin cam cars - the distance between the 2 marks should be

new - 147 +- 0.1
worn - 146.6

so if your head measure at or below 146.6
you WILL need the thicker head gasket a shown here

and the difference between a 2.5 twin cam head 'and the 3.0 twin cam head

and
NO YOU CAN'T PUT A 3.0 HEAD ON A 2.5
OR THE OTHER WAY AROUND !!!!!!

and the thicker head gasket for heads that don't meet factory specs

2.5 s -= 100 mm



s2 3.0 = 104 mm
