Does anyone have the part numbers for everything that needs to be replaced? I have a family member that is a mechanic and will do the work for cheap. He just did my clutch less than 3k ago.

No blown gasket yet.

But the tranny or differential or something is shuddering during sharp turns or when slipping on snow. Any ideas? I'm going to change the fluids and see what happens.

And should I be expecting HG issues for sure? I will be doing the timing belt by mid spring time probably, and am wondering if I should just pull the engine and do HG's at the same time?

There is much vibration and when the cylinders are unsupported at the block/head interface, the gasket will fail. The failure will be earlier where the sealing area is narrow. When internal combustion engines were first built, the seal between the block/head was a big problem. Many engines were built with the head an integral part of the block. It makes for a less expensive casting when the deck is left open.
Honda blocks are open deck, and do not have HG issues.

After a year of poor gas mileage and unexplainable oil consumption, my wife's Outback decided it wanted to keep it's oil in the radiator and it's coolant in the oilpan! Bugger! Thankfully triple-A's extended tow service (through my brother-in-law) works at the top of a mountain, in 23F weather, with disappointed kids, on Christmas day.

A swap from the 2.5 to a 2.2 looks like the cheapest option.

At least my 85 GL works!

Cracked block! Fortunately all other services done on schedule.

Remedy: New used shortblock. Machined original heads (C-Tech Performance). New H gaskets, belt, tensioner, waterpump, seals, etc.

This engine is one hothouse flower, isn't it? I still can't bring myself to hate it, though. Meanest sounding sub engine I've ever owned.

Car was purchased, heater didn't work, thermostat, and soon after, the head gaskets were replaced. I assume the car had a blown head gasket while on display for sale, shady business. She runs smooth as hell now.

* Previous Owner had HG's replaced at 92,### by general mechanic shop (not sure which HG's used...)

* I Purchased at 97,###

* Had HG's replaced at 111,### at Subaru Dealer (who used the OE 610's) last winter

* Just this week I have oil in the coolant and coolant in the oil at 127,###

I really want to love this car, but...DANG....

Earlier tonight I saw a photo of the open deck design of these blocks. Does not look like the cylinders would be very stable. Does anyone know how much to have block modified to close the decks?

Looks like a blemish on an otherwise (mostly) decent record....

Is there a list of parts that need to be purchased before doing the HG on a 98 GT?

HG Part #: 11044AA610; also thinking of the coolant additive.

Anything else?

I might just sell this car and my 95 project car and get an STI.

Oil in Coolant, crappy gas mileage, bogs down on occasion.

Also, oil leaks from both valve covers, main cam seal, crank seal, and timing belt is oil soaked...

...oil decided to leave engine bay through driver side wheel well...leading to no brake pads and some lovely burnt oil scented rotors...

time to sell it.

99 LGT, 101k miles. Got home yesterday and I was leaking oil bad which was then burning off and smoking. Coolant is fine. All signs point to cam seal.

Edit: Nevermind, it was bum oil filter/seal. Thankfully no damage was done to the engine.

Default News investigation

Subaru of America is saving millions of dollars by responding inadequately to known problems with leaking head gaskets in its 2.5 L 1999-2002 engines. Information is being compiled for publication of newspaper and magazine reports and a class action lawsuit in connection with WWP-99, Subaru’s service bulletin, which acknowledges the external coolant leak problems.
In transparent, profit-motivated efforts, Subaru is hiding behind a smoke screen with a band-aid coolant approach to pushing engines beyond the 100,000 mile mark, at which time warranties expire and the ‘stop leak’ coolant creates critical damage to engines. This product stops up radiators and causes engines to overheat. The number of Subaru engines with recurring head gasket and overheating problems needs to be documented, and brought to the attention of the public and National Transportation Safety Board.
Subaru’s inadequate Customer Service response to these costly head gasket repairs is turning many loyal Subaru owners away. Subaru owners with leaking head gasket and overheating problems may send their reports and comments regarding such problems to: subaruinquiry@sbcglobal.net. Please include your e-mail and telephone number.


I purchased a Subaru 2001 Forester after doing extensive research to find a car with low maintenance costs, longevity, good fuel economy, and safety. My Forester has been the most expensive vehicle I’ve ever maintained. This car began having overheating problems as soon as I purchased it. The radiator was replaced. Soon after, I received the recall for adding special ‘coolant’ to postpone the ultimate damage caused by leaking head gaskets. This car leaked incessantly and I was always adding coolant. In 2007, my Forester began smelling hot. $3,000 later, a number of repairs were made including a new water pump, oil cooler, timing belt, and head gaskets. In June 2008, coolant was still leaking. My Subaru overheated, leading to a complete meltdown of the engine. The repair bill is $6,000-$7,000.

Please help me in documenting head gasket and overheating problems and taking action to make Subaru pay for its irresponsibile handling of these problems.

Hello,
I'm looking to buy a 99 legacy outback wagon 30th edition, with 74,821 on it. DOHC H4 PFI 2.5. After reading all of this I am a bit leary. Do you think I should request the HG is changed before I purchase it or will that just prolong the process until it blows? Should I just look for another year? Someone ran into my car and I need to make a reasonable purchase without spending over 10k and this is at 7400 so I figure it would be a good deal if it runs at least 50k.
Sorry to hear of all these troubles. Subaru have always seemed really reliable to me.

Good head gaskets

This has been the toughest car I have ever owned. I put 100k miles on it in three years. I replaced the cam and crank seals at 160k, I also went ahead and did the timing belt and water pump. Only took about an hour. Despite the ATX mine has spent alot of time over 4k rpms. Most of my mileage has been pizza delivery. I bought it from a retired mail carrier, so the second part of it's life was mail delivery. It was a program car when she bought it, which is code for rental car. I want to lift it and do a WRX conversion on it, but I think I should replace the *original* struts first.
