[s-cars] No love? Uh oh - Headgasket failure?

[Ed Walsh]

Thank you, Bob, for the help.

It does sound plausible that the turbo is leaking.

Still no oil in the coolant and no coolant in the oil.
 I think that it is typical to see either/both with a
HG failure.  Still boosting fine. Still not
overheating.....

Would anyone have a link to a picture/diagragm of the
water cooling passages in the K-24?  Is the turbo
leaking coolant into the intake even a possibility?

Thank you for any help,

Ed (hoping he will soon have a new RS2 turbo)
