Well my 2008 Outback H6 with 154K miles on it started blowing white smoke on start-up about a week ago. This was heartbreaking as I just replaced the entire exhaust, including magnaflow headers. But the smoke only lasted for about 5-10 seconds every time and the car still drives great. Figuring that at this age/mileage, I am not likely to foot the bill for a head gasket repair at about $2500 minimum, I decided to try K-seal head gasket sealer. While I was at it I burped the coolant. There were no real results initially, but after 1 week, the white smoke on start-up has gone away. I understand this is by no means an optimal solution to a slightly weeping head gasket, but so far it seems to paying dividends... I realize there will be a thousand trolls telling me I made a mistake pouring that "crap" in my coolant system, but there again, it is probably folly to pay $2500 for head gasket replacement when a multitude of other issues may be lurking, including eventually, brake lines, etc. For now, fingers crossed, she drives great...

It was likely normal condensation build up smoke and not a HG. When I went to a new exhaust, I started seeing more condensation burn off. Just figured it was from water being slightly trapped in different spots. And high flow cats.

Possibly, but the smoking didn't occur until 4 months or more after the exhaust install, and we are talking a large quantity of smoke, which now has disappeared after K-seal. But I freely admit that I can't confirm a head gasket issue. Maybe some condensation is getting into the exhaust somehow, but time will tell.

The other thing that makes me think it is a head gasket weeping issue, is that I could see whitish specks of the K-seal ceramic stuff in the exhaust tips.

My 05 has done this a few times within the past year or so and it's at 219K. Pretty sure the headgaskets are worn out - but not enough that I can't still drive the car like a normal person without it trying to overheat. If I push it hard in the mountains, it'll push too much coolant to the reservoir and then try and overheat when not moving. I honestly think I could get this engine to 300k in its current condition just by being kind to it and checking fluids all the time.

On a side note - would you buy those Magnaflow cats + headers again? I need a new exhaust myself and am considering the Magnaflows or Pacesetters.

Changed the oil and filter on my 3.0 H6..
it took 6.8 quarts 5w40 Shell Rotella T6
to reach the top hole on the dipstick, cold

the manual says 5.8 quarts, but that is a copy paste error
SOA says 6.9 quarts
I trust the dipstick.
Yep! I usually buy 7 quarts for an oil change and keep what I have left over in the car to top off my various oil leaks.

JDM engine swap inbound for this guy!

went to Firestone for Wheel Alignment. While waiting the service writer comes to the waiting area and tells me the car needs a new battery, for $167. I thanked him and said, not today, but I will think about it.

I then went to my local Subaru specialist, and asked to buy a battery. He said, "Let me test it first". and came back with, "Your battery tests fine, there is nothing wrong with it."

It is an MT35 Interstate Battery that is 46 months old. I carry a jumper pack in case it dies, but since I put a jumper pack in the car, the battery has not had any failures to start the car. I think it knows I mean business.. if it does not behave, its gonna be my way, or the highway.. LOL

fwiw, the AAA driver who jump started my car twice last year, told me it was testing bad and needed to be replaced, but then too, the local Subaru specialist said it tested fine after a recharge.

I like to get more than one opinion on things.. so I can pick the opinion I like ;-)

I would just test the battery by feel... does it crank slow first thing in the morning?

I just replaced my Bosch AGM battery two days ago, 15 days after the 4 year free replacement warranty. The new battery starts the car so fast. It was difficult to notice the old battery gradually starting the car slower by the week until one day it didn’t want to start.

I checked to see if the alternator is working by unplugging the positive cable while the car is running to see if it still ran properly, which it did.

A slight concern after replacing the battery (resetting the ECU) is that the car would idle at 500rpms and would not react to any throttle input below 1/3 pedal movement. Luckily after 30 miles of driving it fixed itself (ECU took time to relearn?) and ran back to normal. I guess I need to replace spark plugs and coil packs!

Removed very dirty cabin air filter

watched a few videos on how to Remove and Replace the cabin air filter on my 2006 LLBean Outback Wagon

the harder way:

the easier way:
There are a lot of different access configurations for the filter. This video matches my car:

I got the filter out, it is very dirty.. I need to buy a replacement filter.. there are at least 3 different versions.. I plan to take my old filter into the dealer, to make sure I buy a match.. They are not cheap..

here is an online source for the filter my car uses:

Yes they are: 2006 SUBARU OUTBACK 3.0L H6 Cabin Air Filter | RockAuto

And even via your link, $20.00 for something you MAY replace once a year (depending on your location/how much you drive), that's a drop in the hat.

the link I had from subaruparts was going to add $10 shipping for a total of $30, so I did not order

the dealer price is $27 out the door... I bought one and installed it.

thanks for the rockauto link
I ordered Mann 72880xa00a equivalent filter for $10 delivered. As a backup.

it looks a little different than the stock filter (4 years old!) I just removed:


but the filter tray in my car seems to be compatible with both the frameless stock filter, as well as the Mann version with the cardboard frame.. next year, when I replace filters again, I will find out.. :)

fwiw, 1.5 years ago I had asked a shop in California to replace my cabin air filter, and was told that my car did not come with one. (translation, they did not want to deal with it).

Now that I know how to do it myself, it will be a much simpler item to keep up with.

I went for a scenic drive after rotating tires and setting cold pressure to 35psi front and rear in the morning.

drove 10 miles on the freeway on a sunny afternoon, tires were up to 40psi, and the ride was a little crisp, or bouncy, particularly the tail, adjusted down to 38psi, which I liked, felt the ride was smoother.

travelled another 50 miles of pavement,
then took a wrong turn, and encountered washboard and river rocks..
the ride was too jarring, could not go over 10mph, stopped and checked pressures, they were at 39, so I aired the front down to 37 and the back down to 34psi..

still could not go faster than 15mph, but the ride was less jarring, and I thought I only had 2 miles to go, so did not want to air down further.. even though I was carrying a compressor...

eventually ended up at a locked gate, and had to turn around and backtrack a couple of miles,
then found my way onto reasonably smooth dirt,
stopped for another photo op:


===
update the morning after
it is 45F outside and the tires dropped to 33 front and 31 rear overnight..

when I was driving 75mph for an hour on the freeway yesterday afternoon, it was 65F outside and Operating pressures were at 37 front, 34 rear..

iow, the operating pressure was +4 psi front, +3 psi rear, compared to 8am cold pressure

moral of the story..
Cold pressure can be very different than operating pressure.. depending on climate.. There was a 20F difference between morning and afternoon ambient temperature here.

Fill tires with Nitrogen = no more fluctuations in tire pressure & you won't get exhausted by constantly having to adjust the pressure. Nice pic!

Do you have a sound system in the space where the spare tire is supposed to go? I dig that floor set-up!
Yes I do! I frequently load the car to the brim with tools and lumber, so I needed the subwoofer out of the way, but with all of the driving I do, I CANNOT be without a subwoofer.

Plus it protects the car. The black mitered 2x4 lip protects the leather on the back of the seats as I slide oily metal or splintered wood past it.

Just remove the floor panels of the trunk, use it as a template to cut the MDF sheet, then attach it to the floor panels so they click back in. I also added a piano hinge so I can still easily access under the subwoofer for my tools.

I understand that it’s a bad idea to not have a spare on hand, but the spare is almost an inch smaller in diameter (not good for the drivetrain) and I plugged 5 tires on the road in the past 1.5 years (work around a construction site so there are nails everywhere). I can still fit in the spare tire space a tire repair kit, upgraded scissor jack, and a jumpers
/compressor. I would like to put the spare on my roof rack but I need the roof rack to carry plywood.

Fill tires with Nitrogen
thanks for the suggestion.. I have no nitrogen experience so I googled it

I do not think nitrogen is for me, because I carry an air compressor and deflators.. left over from my Full Locker VW Syncro Westy 4WD days. That means I have the option to change tire pressure IF Im offroading (in my mind more than in my car.. lol).

I just installed the window visor from My Car Worx (Tape-On Outside-Mount Window Visors (Shades Weather Air Snow Vent Deflectors Rain Guards Shields) for 2005, 2006, 2007, 2008, 2009 Subaru Outback Wagon and Subary Baja, one of many Accessories, Custom Auto and aftermarket SUV parts and cool enhancements at MyCarWorx.com ).


I couldn’t find any one piece visors from eBay or OEM other than the $10,000-$11,499 ones on subaruparts.

It looks alright. It came with 3M adhesive. Installation was easy... just pre-fit the visor with tape, make sure the window clears, and peel and stick.

This is just an initial impression, but I hope this will stop rain sitting on the roof from pouring in like a waterfall and minimize the dreadful highway noise from the frameless windows.
