#5483 of 19336 Re: 2005 Subaru Forester [pamela3] Pinging
Aug 09, 2005 (3:55 pm)
This is a follow-up from two or three months ago concerning pinging in 2004 Forester XS...
Well, after much back and forth between dealer, SOA and myself, problem still exists. Pinging with regular gas, especially under load (gentle hills, A/C on, passengers in the vehicle). This is moderate to gentle driving with 24k miles.
I waited two months for a call-back from the dealer only to have the district service manager test drive the car and report 'performing withing specs'. Unfortunately, I couldn't be at the test. The dealer referred me to some vague statement in the manual about knocking with this type of engine being normal (also told me incorrectly that this vehicle required premium fuel). I followed up with SOA saying I was still unhappy and was told by a stubborn representative that there was nothing wrong with the vehicle. He made me feel like I was the one at fault.
I am very unhappy but have given up. I'm stuck with premium fuel now (91 octane) because this produces the least amount of pinging. But at $2.90 a gallon (US-CA) and the lousy customer service, it's a case of 'first Subaru, last Subaru' for me. When it's paid off in another few months I'll be looking to get rid of it.
Hope everyone else with the pinging problem fares better than me.

Change the PCV valve.

Anybody experiencing a rattle in the sunroof area of a Forester? I have an 05 and it rattles like heck when I'm going over bumps; its a relatively new occurence as I've had no such issue for just over 10k miles ....

I had the same problem with a 2004 Forester X. Night quite as bad as yours though, although it would ping moderately with 89 octane and badly on 87. One cause of the problem is combustion chamber deposits. I added a full bottle of Techron concentrate ($6 at Wal-mart) for three consecutive fillups and haven't heard a ping since even on 87 octane (in 1000 mils).
I'm really skeptical of "mechanic is a bottle" products, but this stuff works. Normally 1 bottle every 3000 miles is recommended but multiple bottles might be needed if your fuel system is really dirty. After the first addition I noticed no benefit, after the second I noticed a little and the third eliminated it completely. The downside is that using the stuff regularly costs nearly the same as filling with a higher octane.
Don't ignore the problem though- its only going to get worse. The higher octane gas is only a temporary solution. You'll eventually ping on 92 also.

It can help.
Miata enthusiasts say you should redline the car once each tankful to help prevent carbon deposits from forming inside your engine. When they form, they occupy space and effectively increase your compression ratio. That can cause pinging in extreme cases.
So go get 3 bottles on Techron, use one in each of your next 3 tanks. And make sure you rev your engine, try to come near redline at least once per tankful.
Also make sure you are not lugging the engine. You don't want it to be pulling a heavy load at under 2000 rpm. Peak torque occurs above 4000rpm, so don't be afraid to rev it up. Especially when you have lots of passengers or cargo, i.e. a heavy load.

I'm referring to the dipstick, its less then one quarter now..., I have 121k on the engine, and feinetely do not drive 500 miles a week maybe 200. i just figured if i keep having to add oil, then something must be wrong, but if you say not to worry about it and just make sure its full of oil then i'll have to go with that. what kind of oil do you recommend i keep in my trunk? i usually have firestone or whomever change it, i've never really had to buy any yet. thanks
#5489 of 19336 "cranking" sound when making sharp turns 96' outback
Aug 10, 2005 (9:11 am)
Another problem I'm having with my 96' legacy outback is when I make sharp turns, forward and reverse, for example pulling out of a tight parking space or pulling into one, there is a loud cranking/ sort of sound, it's almost as if the car is trying really hard to pull off the turn. I was told by one mechanic that it's a problem with the AWD and that some sort of lock is in place in the transmission. He said not to worry about it though, I cant help but worry cause that sound just gets to me, feels like my car is just going to fall into pieces after Iomplete a turn. Any advice?

I would have a mechanic inspect the CV joints and the wheel bearings.

i had them check the cv joints, they were fine... and i know the sound of a badd wheel bearing, its definetely not that, more like a ratchet type sound...

Sounds like binding.
Can you drive in a tight figure 8 in a dry parking lot? See if that improves things.
Also check the circumference of the tires, they should not vary by more than 1/4".
