NG900 & OG9-3 Workshop
My saab 9-3 turbo has froth in the oil.
There is no performance loss, no oil in the coolant, no overheating, no water in the plugs, no smoke out the exhaust, no bubbles in coolant when running, etc...... no other inidication that it could be the heag gasket.
The PCV system was screwed up...
