  1. Nice! No, I did not see that. Thank you for sending me this and I'll read through it.
  2. Hello all, I'm a bit of a lurker, and read a lot of the posts here. However seems like there is very little for the 3.6r. Guess it is not that popular of a motor. Car info: 2016 Legacy 3.6r 74,000 KMs Purchased in 2017 with 19,000 KM on the OD (One year lease back) Subaru Canada calls for plug changes at around 100,000 KM. Dealer wants to do it around 80K I'm getting a very minor miss when cold on the 3.6r. Once the car is starting to warm up, the motor is as smooth as it was when I purchased. I origionally got it because I traveled for work and wanted a better highway and winter car. (Had a 2010 FFH) So most of the miles is highway miles and about 40K was put on in the first year of ownership. I'm not sure how long I've been getting the miss (maybe stumble is a better description of what I'm getting) so I figured I wanted to get a look at the coil packs and change out the spark plugs. Watched a few videos on people change out the spark plugs on the 3.6r (outbacks) and did find a post on here about someone else doing it on a 2011 so I figured I was ready to go. Boy was I wrong! I'm not sure if I knew how much trouble it would be if I'd have taken it on. https://legacygt.com/forums/showthread.php/3-6r-spark-plug-replacement-256538.html For anyone look at doing this themselves there are a few items that slowed me down. The job took about 4 hours of my time (with at least 1 and 1/2 hours on top of that going back and forth to the local Crappy Tire store). Lets start with the tools you are going to need! 3/8 Plug Socket (with a rubber boot) 3/8 Ratchet 1/4 Ratchet 1/4 10mm 3/8 10mm 3/8 12mm deep well 3/8 14mm 3/8 U-Joint adapter 3/8 1 inch extension 3/8 2 or 3 inch extension 3/8 8inch extension (That is the longest I had. a 10 inch would work too. 14mm wrench with a long handle (for 2 bolts on the metal bracket on the airbox pointed to the head (this really screwed me up) ratching if you can get it Small Flat Head Screwdriver Small pick Large Flat Head I'm not going to go into a lot of detail, but this is not for the faint of heart. Take your time and don't rush. Also make sure you have all the tools you need up front. I did not, and had to run to get some which slowed me down. And yes I had what I though I needed. Have a second car on hand in case you need to get something with the car pulled apart. That saved my.. well you know. On the Legacy 2016 3.6r for the drivers side you need to remove the battery, the plastic battery box, plus a metal battery "box" under all of that. This box has 6 14mm with 2 of them pointed twoards the head. If I had a ratching 14mm wrench this would have been quicker. 6 bolts for this just seem like a way for Subaru to make changing plugs on this car impossible for the average joe. I have not yet put the 2 bolts back in the battery box pointed to the head. Not sure I will. The first 2 plugs and coil packs on the drivers side is pretty easy. The 3rd is a pain and caused me way more of a headache than it should have. Don't for any reason use any extension in this socket. Just use the U joint. I'm warnining you now... I almost had to get my car towed to get it out. The passengers side is not as bad. The 2016 model year is when they added the electronic power steering setup so some of the hoses that make that side harder are not on this model. You need to remove the air infuser, air box, and I took out the air routing to the throtal body to give me more space. Again plugs and coil packs 1 and 2 are easy, 3 is a pain, but not as bad as the driver side plug. Same on this one, don't use a extension on plug 3. After 74k KM the plugs showed some wear, but I think I could have easily gone to 100K KM easily on them. I will hang onto them for spares should I need them. The coil packs are another matter. 3 of them are rusted very bad, and have some degree of the metal seperation on them. the other 3 are in fair shape. The car is still under extended warrenty so I will get Subaru to replace them at the next service. (Should have moved both back coil packs to the front, but why make their job easier, eh?) And yes they are covered, but I do have to pay a fee for checking them out... Even with the pictures I took. If anyone has any questions, please ask away. Up next, the front pads and brake service. Can't be that hard, right?
