2007 Cadillac CTS Engine Block Leaking

[John Jesmok]

ENGINE BLOCK LEAKING
I own a 2007 Cadillac CTS with V-8 engine.
I had the car in for a service check today and they said they could see signs of oil leaking from the engine block.
Nothing could be done today but they actually warned me of potential problems in the future.
Mileage is 78,500.
Is there anything I can use or do to slow the leaking problem so that it doesn't cause a major engine overhaul in the future.
I have a warrenty up to 100,000 miles but it's not leaking enough now to use that and get reimbursed.
Any ideas?
John

These engines have gasket problems. They seem to all leak oil from everywhere. You have a GM factory 100K mile powertrain warranty that will cover this for free. Not sure what you mean by "but it's not leaking enough now to use that and get reimbursed", any leak is a leak bad enough to get fixed. There is no magic additive or anything to cure this.
