This 2004 Buick Lesabre is in because the customer plans a drive to Louisiana and needs an overall check to ensure it’s roadworthy. He also stated the vehicle had been losing oil pretty quickly. Like most older vehicles, I generally expect them to have leaks, as seals don’t generally survive the test of time. Once we got it in the air, I discovered that this was the cleanest Buick I’d ever seen, with not a single leak or seep to be found. The customer is serious about his maintenance, and it shows. If he is actually losing oil, it’s got to be burning it because it’s definitely not leaking.

Quick check… Take off the oil cap while the engine's running and feel for blowby
PCV system on those works get gummed up. Top end cleaning new pcv and plugs it’ll run like a champ for much longer
3800 blow heads
Combustion chamber cleaning?
Too bad it's not an ultra

My Dad Commuted for Longisland to NYC for years . He bought a 2004 lesabre with 2k miles by 2013 i had my car in the shop so i borrowed his lesabre and the miles was at 495k. Original motor and trans. I was shocked. 3800 motors if you take care of them u will have no problems but normal maintenance. Also as stated the car still got great MPG over 30 mpg and decent power. Paint was great also bc it was garaged.
