Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

problem #1

Eldorado ETC 4.6L

Engine used quart of oil/500 mi. GM standard is a quart/1000 mi. R&R engine cradle, disassemble engine to find bad piston rings. GM had a Tech Svc Bulletin in 04 about this problem. Turns out that oil had been getting past rings into combustion chamber. Otherwise, pistons & bores looked perfect. Cleaned carbon off valves & piston tops & heads, replaced rings, broke in starting at 50mph, & increasing by 5mph every 100 mi. Now she doesn't burn a quart of oil in well over 6000 mi - I haven't pushed it to see how far it would go. Major pain, required long use of rental/loaner, not to mention all the expensive oil I had been burning. $4000 job paid for by ex. warranty. I had to pay for misc. filters & new lubricants. Now using Mobil 1, and fantastic oil mileage continues at 23000mi on the job. Looking forward to many years of 'new engine' use & performance.
