My take is that a bad head gasket design is the source of the problems. It appears this affects model year 1996 (or 95?) to 1998 or 1999 phase 1 DOHC engines the worst (with internal leaks). Appears to be a little better (external leaks) with 1999 or 2000 to 2002 phase 2 SOHC engines.
Actually, what is not really stated here is a block change over the years as well. The phase-2's and up had support ribs from the external walls of the block to the top of the cylinders. The phase-1's didn't. This allowed the cylinders to wiggle around which "wore a hole" into the HG.
Using later model HG's helped this, but did not totally fix it.

I finally fixed it by using a rebuilt STi 2.5L SB and my original DOHC heads.

"This problem, and Subaru's lack of response to it, have soured me on the purchase of newer Subarus. I bought my wife's 1999 Legacy L w/ 2.2 L engine in 2000 knowing that even then there were "rumors" about 2.5 L engine reliability. I'm REALLY glad we went with the wimpy 2.2 L. I'm disappointed that we had to replace the 4EAT this week at 100 k miles.

I used to think that I'd buy a new or slightly used Legacy GT some day. Now if I got a Subaru it'd probably be a 98-99 Legacy L w/ 2.2 L and 5MT. And I'd avoid the dealerships in favor of a local independent Subie specialist."

Michael, A used GT might still be okay, you just need to find one that has had the head gasket replaced under warranty. I am thinking of selling my GT and getting a RAV4 V-6. I would hope that having all my service records would make it a preferred used car. Lew

My understanding is that fixing it might buy time, but that the HG will eventually go again (perhaps 50-100 k miles, but could be any mileage?). Or is this just for the Phase 1 motors, and the Phase 2 motors can be fixed completely ?

I don't have a definitive answer for that, but the design of the gasket was changed, so I would hope it would go longer than the 60,000 I got on the original. Lew

Guys, I just sold my 2002 GT and bought 2007 RAV4. Thanks to everyone here who has given me help with mods and fixes. This is a great website.

Anyone know any similar sites for Toyota owners? (I splurged and got the V6 for driving in the mountains. It is supposed to get good gas mileage if you don't drive it hard. I hope that is true). LewBob

Charlie-III Where did you get the STi short block? Any particular problems lining things up? Do you still have the piston rattle? Did you use the stop leak additive with the new block? (I hate that stuff)

Default Open deck - closed deck

Did some research on the subject of why these head gaskets fail: Found that the 2.5 liter engine block is/was designed with an open deck. The cylinders just stick up into the air. I have never seen such a design. Cylinder blocks have a solid deck with holes for circulation of coolant and oil. It is of no surprise to me that the head gaskets fail. 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.

I've been told it's got a HG leak but I don't see the classic symptoms (e.g. low coolant level with no external leak). It does leak oil though, can't find the source of that leak.

The classic symptom is overflowing coolant from the reservoir after you have run hard for a while. If you want to see action try flooring it while going up a long hill. Then pull over and look for bubble from the rad into the overflow.

Also take a good look at the bottom of the overflow. If there is an abundance of black goop...

Oil Leaks:
cam seals
crank seal
rear separator plate
rear main seal
cam cover gasket
cam cover bolt
spark plug gasket
oil pan
oil drain if you reused the crush washer or didn't use one
All these leaks are a design feature to prevent rust in your engine bay.

No problems.. the only thing is that there's a quiet clicking noise when I'm accelerating.. doesn't happen while I'm standing still and revving though.. any idea what this could be? I recently had everything looked at and fluids changed etc. and the mechanic didn't seem to think there was a problem. It's just sort of annoying.

The 2.2l doesn't have the headgasket problem. Its the most reliable motor subaru made in the 1990s.
The clicking is OK, there is more clearance in the valves so they make more noise. Not much you can do about it unless you spend big $$ to reshim the valves. Just roll up your window and turn up the tunes. The EJ motor will never win any prizes for quietness or smoothness.

Well, with the earlier EJ22s, it's hydraulic lash adjusters, and it's actually a pretty simple DIY and about 100 bucks in parts to fix it.

Mine have gotten noisy again. It's too bad, I was enjoying the smooth purr it used to give me

...2 do to the dang purple bottle that sprays this funny type of gas (one time in a race and one time on beltway-495) ...1 do to removing this purple bottle for some aggressive cams, aggressive torque convertor and aggressive throttlebody...instead of breaking it in properly...tried to play with a ZR-1 and lost! Engine kapputt!


That's my horror stories with the '99 GT

BTW, I sold it in 2003 and it didn't even have 100,00 miles on it.

'98 Legacy GT DOHC 2.5, 5 spd; blown HG @ 98K; replaced and now @ 146K and still good.

'99 Legacy L 2.2 SOHC 4EAT; blown when I bought it @90K (yeah, I wish I read this thread before I got it) - replaced HG (no resurfacing) and ran fine for about a year - then again @ 111K - still trying to figure out what's cheapest/quickest to do. Not sure if anything's cracked or not, but coolant is in oil in the oil pan.

My 1996 Outback blew at 200k. Original engine.

Did both sides at the same time.

Eventually all EJ25D's will eat atleast one set...usually the originals. Once the new metal ones go in...zero problems.

Sorry, haven't been on here much lately.

The STI SB is a modded block from Crawford with higher CR pistons.
No issues bolting things up.
Used newer version Subaru HG's.
Heads are redone 2.5L DOHC ported and polished by COBB Tuning with COBB street cams, upgraded springs and light weight spring retainers.
No "stop leak" used in the new engine.
