How about $0!!!!! I am assuming a cable throttle body and not electronic. Change brands of gasoline. The different additives in another brand will remove the trash another brand left behind! 2-3 tanks should be enough.
In the electronic T bodies, they are servo motor controlled. Different issues there as well.
As for everyone else.....the MO Subaru fleet seems to have caught a head gasket virius! One completed and returned to service. The other two have been caught failing in early stages at 250K miles or more of service. The best I have seen about this issue on web is the following web site. The most recent failure was on a replacement engine with an estimated mileage between 80-100 service. That estimate is based upon exam of cylinders and deposits found in the oil galley.
Two very experienced mechanics, myself included, cheked this website out and found that this guy seems to be very much on target with the problem. He nailed the issue to a t on this 98 engine I serviced last!

Very interesting - my '97 Outback's battery has always generated more "chia pet hair" than any other car I've owned. Every time I read a post like this it makes me want to sell it so I won't have to deal with the inevitable head gasket failure. And winter is winding down....

My Escort fit that bill for me: It was terrible about battery terminal corrosion. Then, I replaced the cables last year and added another large grounding strap from the negative terminal to the body.
What do you know? No corrosion at all the last year I owned it! In other words, it's a resistance game. Try adding (or replacing) a grounding strap on your car and see if it makes a difference.

I walked out to the garage an hour ago and popped the hood and the battery is pretty clean. The petroleum jelly I smeared on the terminals back in the fall may have helped? Took a good sniff of the coolant overflow tank and it smelled fine (didn't really smell of anything).
Got the craigslist ad drafted but maybe I'll talk myself out of it. Just makes little sense to have two cars when neither gets driven that much.

Tesoro gas makes my car run like ca-ca. Switched to Chevron, issue fixed. Costco has 5 times the EPA required additives, and I fill there when I shop as well. Like someone else suggested, try a change of fuel flavor first.

Interesting. After reading the article and tearing the first, right side easy to remove head, I went to the left side. That side was a bugger to get off due to corrosion. It also had the worse leak problem.
Needless to say, conversation ensued about relocating the ground strap. I have added another one on an 89 Mazda a few year or two ago. Nice to hear the Escort experience. Might be worth trying it on the Subie as well. The left side has a bunch of timing electronics there. Cam shaft sensor on head. Ground on block. Think that thought out later to try. As for the article about running Subies and not storing. That does seem to be the case. 1st engine died a high speed head gasket failure. Lost it at 286K. The one I service as stated before, could not have had more than 100K is clearly a 98 engine. Clearly a acid build up from oil/blowby gases? The 94 I am getting ready to deal with is at 247K and the youngest '03 unit is at 271K. I am dreading the last one. It will be work on every end of that sucker including valves. Oil galley, clutch, rear main, head job, timing set and everything else up front. Been a very trouble free unit. Everything in house. Too many mechanics have overcharged and beep beeped up! My new curse word! FCC approved!
On the other hand, by having extra cars in the fleet and grouping together with other family members who can drive, we can take the time needed to do a job right and not cut corners.
But before you holler.....sure beats car notes! Some states also have provisions to keep your tags, remove your insurance and store the vehicle. If you do this like me, make sure you tag the steering wheel that unit is in storage so a family member does not take it out when it is grounded! This is also a good time to pull maintenance. I rotate them in and out of service so they all get some use. The older cars are great for winter if they have heat. We save the newer ones with good a/c for summer.
As for the "the inevitable head gasket failure" I always say, anything goes over 200K: things get interesting above 300K! I try to move those cars to winter use in LA. We have a lot of snow here you know! So Steve, I hope you reconsider keeping Subie around. Hard to beat that 4 wheel drive system in snow and the maintenance is not all that bad. Besides, several of us in forum have a lot of road we have already been on. Oh, highway unit....fuel pumps go around 250K+! We now consider pulling before it beeps somewhere in nowhereland. Another thing to add to that 03 list to do.
Second ground.....maybe attach somewhere on left head? Graphite head gaskets not the greatest conductor. Painted new head bolts not great either. Thoughts anyone? Attach to mounting bolt on front bearing housing near cam shaft sensor?

We have snow in the forecast all week and there's a fresh inch on the ground just this morning (and it's still falling). Here's a pic from last week's shoveling out the in-law's drifted sidewalk.
I dunno, the van is more comfortable to drive and we could borrow the in-law's Buick if it died and we needed to go buy something. After 13 years, we're at the point with the car fund where we can pay cash, but interest rates are so low, who knows. Just don't like owning stuff I don't use and would rather see someone else run it into the ground (and freeing up half the garage would be nice too).
Maybe one more winter (for the car and me. ).
#19271 of 19336 03-07 Forester Head Gasket Failures
Apr 30, 2013 (2:31 pm)
CR has posted a story today, apparently based on updated results of their annual consumer survey, of various used cars, foreign and domestic, to avoid because of problems. The Subaru Forester, 03-07, is on that list because of HG failures.
I'm disappointed to see that CR readers are reporting HG failures in their Foresters. Subaru had led me to believe that it had solved the HG failure problem a few years back with a different gasket material and the required use of some sort of radiator stop-leak. Subaru has to have known that the HG leak problems were continuing and only changed engine design recently.
I suspect this means that anyone who owns a Forester of that vintage, or perhaps even an Outback or an Imprezza (similar engines) is going to find that their vehicle is going to be valued less at resale or trade-in because even a vehicle without a failure now is at greater risk for needing an expensive repair sooner than later.
I sure hope that Subaru redeems itself by extending the warranty on HG repairs to at least 125,000 miles. A modern engine that is properly maintained should not need an expensive HG repair even at 125,000 imo. The article doesn't tell us at what mileage HG failures are occurring.
We've owned five Subarus since 2000, and so far have been lucky. Or it may just be that three of those Subarus are H6's, which appear to be pretty much immune from the HG failure problem.

I have 3 Subaru's under my care. 94, 97 and 03. The two older units as of now have had HG jobs. 250K, 94 and 97, 289K which that engine was lost due to a high speed failure only to have the replacement 98 engine fail at an approximate 80-100K miles of service. This is a very old problem for Subaru.
Like I tell people, if it can not make 200K historically without major maintenance, it is junk on the lot brand new. Needless to say Subaru is not on our replacement vehicle supplier list anymore unless it is needed for 4 wheel service applications! Shame for Subaru.
As for the H6 engine, it shares the same design flaws, but keep your oil changed and try to operate each car at least 10K or more miles per year. Check out the following website to read why these gaskets fail and use those preventive measures. You may be all right. Several of us agree these guys may have this figured out. http://allwheeldriveauto.com/subaru-head-gasket-problems-explained/ As you may have already noted we pull a lot of miles out of Subies as well. Oh, I failed to mention, the 03 is in failure mode at 280K currently.

I checked with my mechanic the other day and he loves Subarus - makes a lot of money doing head gasket jobs on them. He pulled a recent ticket and the bill was around $1,300. He typically doesn't see them until 160,000 miles or so though.
Mine is at 92,000 miles after a ~16 hour RT cruise to Chicago and I've decided to try to get one more winter out of it.
