Oil was 1/2 quart low, a friend was borrowing it and the motor started knocking. She drove it about 3 miles before realizing that it was knocking. I put oil in however, I ended up putting 5 quarts in. The motor is not seized up, the knocking has subsided a little bit but has not quit. The knocking gets worse as the vehicle idles up. I was told it could be a crank bearing?? Please help.

Your hearing lifter noise common in most cars in cold weather I have a 2001 sc1 same engine as yours here's how to get rid of that ticking sound go buy a quart of Lucas synthetic motor treatment change your oil and leave it 1 quart low add the Lucas synthetic oil stabilizer within 1 week you will not hear the noise agian reason your hearing the noise is there's no oil at the top of the engine on a cold start oil when cold is thicker hints why your noise in your engine what Lucas does is eliminate the dry start by the way my engine has 288,000 and does not use a drop of oil after you use this product you should use it every oil change you will see your car will thank you regards Chris
It sounds like a weak lifter. When the oil is down 1/2 quart, add 1/2 of dextron ll instead of oil. This will help fill the lifter so it won't collapse again. Also look down the hole when you take of the oil cap and make sure it isn't filled with engine sludge. If you see some, get it cleaned out by a garage.
what would a CV joint have to do with oil consumption? the answer ZERO, if the VC gasket was leaking that bad you would have a large puddle of oil under the engine every time you parked it for more than a few minutes, so doubt that is the problem, has the dealer run a clyinder leak down test to determine if the piston rings are sealing properly? that is the next step, sure sounds like they don't know what they are doing and they are guessing, make them do it for free, they changed out the turbo for no reason it seems, u are out $1800! and no change in oil consumption, make them do there job right or get ahold of the dept of consumer affairs for your state and open a case, that will light a fire under there ****.
I had the same problem with my wife's 2006 passat turbo. We lost 2.5 quarts in 3000 miles and the warning light came on. They put us on a 1000 mile oil test and I lost 1.8 more quarts of oil. They finally agreed to replace the rings. Service tech told me that the factory rings are defective, they begin to lead after about 25,000.
