Started car and now it blows crazy amounts of blue/grey smoke, but idles just fine. My guess is a piston ring(s) was about to go and the fresh change to a thick oil from the thinned out used oil caused it/them to finally go. Any thoughts? Other opinions? Not my car by the way.


"New" to you used car? Then it sounds like the previous owner used a thick oil treatment, like STP oil treatment in addition to the 20W-50. When you changed the oil you drained that also. Just my

you need to get the engine looked at by VW and they may honour a tsb for the engine

VW Technical Service Bulletin 1701-01

basically the rings were not installed properly (no stagger) or didn't seat in the block, turning your car into a 100:1 two stroke engine (lol i only drive vw diesels)

the 20w50 was used to hide the engine problem, the repair requires new rings and honing the cylinder bores, my friend had her engine repaired by the dealer under the tsb,

oh, you will also need a cat converter, its probably plugged with engine blowby

sorry for the bad news



This.

My sister had an '01 Jetta 2.0L and I was told the same thing by a guy who builds VWs. I put 15w40 in it and the car still burned a quart of oil every two weeks. It only had 110k miles on it.
 
As mentioned in the last line of my initial post, the car is NOT mine. Was playing poker with some friends of a coworker and one of them told me the scenario and had me look at his VW to see if I had any ideas what happened. Thought I'd post up on here to see what ya'all think.
