any time I see one of these on AZ I grab it and bring it here
Just got car back from dealership. Had compression and leakdown test done to gauge engine health due to visible smoke during engine braking. Car has 79000 miles still under CPO. Burns less than 1 quart of oil every 1000 miles. Here are the numbers, please let me know what you think:
Comp Leakdown
#1 170 7
#2 170 10
#3 165 10
#4 160 10
#5 145 10
#6 145 8
#7 145 25
#8 160 12
They said that during leakdown test #7 was shown to be leaking into the crankcase. Boroscope showed small scratches inside cylinder wall.
I asked the tech what the minimum wear values were, but he was of no help. I am concerned with the leakdown of 25% and wanted to know if anybody had some technical specs from Audi concerning these matters.
Thanks
