question about lifter tapping

[kyle leatherwood]

Brady,

I must admit, I too love to use pure synthetic motor oil, I used it in my 
former car, an 89 Ford Probe GT with no problems (from 89,000 miles to 
210,000 miles) such as leaks, oil consumption (about 1/2 quart every 5,000 
miles) etc.  But when I purchased my 90 Audi 80 a little over a year ago 
with 102,000 miles I again went to Mobil 1 15w40 synthetic.  To my 
astonishment the rear seal started to pour oil out after driving it about 
2,000 miles.  Now I am exaggerating the "pouring out" a little bit, but it 
started to leak a quart and a half every 1,000 miles. So I went back to some 
of the "high mileage" dinosaur juice and it slowd up to a tiny drip. No more 
puddles in the drive.  Now that I have purchased a 90 V8 Quattro with 
103,000 miles on it I am scared to try synthetic in it.  I know it would be 
the best thing I could run in it, but I really loathe thinking about having 
to pull the tranny out to put in a new rear main sea,l or to replace any 
lower seals for that matter.  I am glad you are having excellent luck with 
synthetics, and I hope a lot of others are having the same luck, but I have 
been frightened away from using synthetic in a vehicle that has not been 
running it since about 10,000 miles or so, at least for now.


Cheers for now!
Kyle
