Replying to: triniluv (Apr 20, 2008 7:03 am) Someone may have unloaded their problem on you. That is a very low mileage car. But before I got too worked up about it, get the compression test verified by a second mechanic (or do it yourself). You or the mechanic should be able to isolate the problem whether it be rings or valves using the wet dry test. If it's valves, and all other cylinders are good, get a valve job only on the side that's bad. Replies to this message: triniluv (Apr 20, 2008 6:57 pm)
#59 of 148 Loss of coolant 2006 Outback 2.5 Turbo by roadrunnerks Apr 20, 2008 (9:31 am)
Bought Outback new, complained to dealer at first service of coolant smell from vehicle after long drives. Coolant resevior low , had to add coolant, dealer states no problem found. Added 1 gallon of coolant in a period of 12,000 miles. Kept telling dealer about problem on each service. Same comment, no problem found. While driving vehicle on vacation a few hundred miles from home, check engine light came on and cruise control light flashed. Vehicle overheated into red zone. Stopped immediately, let cool, added 4 bottles of drinking water, drove back home without overheating. Took the vehicle to the dealer, they stated that the head gaskets were blown. They replaced both head gaskets. I picked up the vehicle, drove 30+ miles home, notice burning smell from engine compartment, hopefully it is only residue from the repair. I am wondering if I should expect problems with the O2 sensor and cat converter. Ken Stroud Replies to this message: paisan (Apr 21, 2008 6:48 pm)

Replying to: triniluv (Apr 20, 2008 7:03 am) Could also be a bad head gasket.

Replying to: roadrunnerks (Apr 20, 2008 9:31 am) My guess would that its residual oil/grease/dirt burning off from the repair, give it a few 100 miles and see if it gets better.   -mike
#63 of 148 2003 3.0 OUTBACK CEL by shiner50 Apr 27, 2008 (3:59 pm)
I put my OB in the shop for a new a/c compressor. I picked up my soob and less than a mile later the check engine light came on. I figured that something was left unplugged by the mechanic. I checked all the connections reachable in the engine compartment and found nothing unplugged. It seems to coincidental to me. Any ideas? I have 81k on it and have had no other issues till now. What kind of scanner does it take to read the codes? Oh, I took it back and had the garage hook it up and check it. They said it was a manufacturer specific code. Does anyone know what that means? Thanks. Shiner50 Replies to this message: ateixeira (Apr 28, 2008 10:54 am) shiner50 (Apr 28, 2008 4:53 pm) paisan (Apr 29, 2008 5:21 pm) ateixeira (May 01, 2008 11:59 am)

Replying to: shiner50 (Apr 27, 2008 3:59 pm) You need an ODBII scanner.   Some Advance Auto Parts stores let you borrow them.   You can buy one for $100 or less. I bought one.   Dealers charge around $80 to scan a single code some times. Replies to this message: shiner50 (Apr 28, 2008 4:53 pm) paisan (Apr 29, 2008 5:21 pm) ateixeira (May 01, 2008 11:59 am)

Replying to: ateixeira (Apr 28, 2008 10:54 am) Thanks for the info..doesn't that seem a little coincidental, I mean the light coming on less than a mile from the mechanics shop after they have been under the hood for a day?
