I have cleand out the ventilation nipple on the crank case cover with a 2mm drill bit and found it was blocked. This I hope will cure the blue smoke I see on start up!
I also checked the code number for the 'check valve' and found it to be 9189564. On the site www.saabs.info
, they say the check valve code should be 9399973. Which part number is right?
I have also looked at the modifications panel and it has the number 8 scratched in panels B5 & C4. I know what B5 is, but what was C4 modification?
Any info will be most welcome as I do not want to have the turbo pulled apart just yet if need be!!!!
