2003-2009 legacy H6 3.0R Do they drink oil? Real world experience please....

[DavidKemps]

Hi guys,

I'm looking to buy a 2003-2009 legacy either the 2.0 turbo B-spec or H6 3.0r.

Was really interested in the H6 3.0R and heard really good things about it until I heard problems with them drinking heaps of oil!!

Does anyone have one that can comment or mechanics about how bad this problem is? Is it rare or affect alot of the cars?

If you have a H6 3.0r and it doesn't drink oil, I'd also be keen to hear from you!

thanks

Dave

No they do not.

Only a poorly example will burn oil (like any other car).

The 3.0 is a great motor. The 2.0T is just a bit quicker and has more mid range torque.

One I test drove before I bought did. The one we did buy doesn't. As far as I'm aware its the 6speed manuals which are more susceptible to it

See this thread:

Boostin and Ichi Ban talking about how much oil the H6 3.0R's use.

Gutted, I really wanted a 3.0R too! Have to risk the 2.0 litre turbo and hope the single turbo version is better than the RSK-B4 dodgy twin turbos Big end bearing problems!!

Are you planning on converting a legacy to single? or getting a wrx? cause legacy's are never single turbo from factory

and all subaru's run BEB's if they aren't looked after, its not a problem specific to twin turbos as far as i know

[funkytown]

Wrong.. The new 2003+ are single turbo.

And the newer motors are much less susceptible to beb as the older

[petrolheadjman]

damn! at least someone knows what they are talking about, ill keep quiet now 8)

[GC8E2DD]

Um, and all the first gen Legacies were singles? What crack you smokin' phjm =P

[petrolheadjman]

the crack of uneducation and not getting my facts right

Need to keep quiet in future haha

[DavidKemps]

Anyone else keen to comment?

I think the difference you may find is the difference between a NZ new car(funky's) and a japanese used import(most of the others) mainly because of the servicing or lack there off,of the Japanese used import cars .............

[GorGasmSpecB]

Get a 3.0 that isn't drinking oil?

I've spent ~$1800 in repairs on my 2004 GT and nil on my 2005 3.0R-B.

Either model that has been maintained correctly should be fine.

[DavidKemps]

yeah its hard to get a good one in terms of drinking oil when I'm thinking of importing it!

what happened to your GT?

Dave

[GorGasmSpecB]

Rear main seal failed, O2 sensor, Bung ICV. While they were doing the seal I forked out for cambelt and water pump.

The engine hasn't blown up or anything, it just turns out that replacing that seal is quite an expensive task.

Hmm I guess it is quite tough to pick without testing the car first heh. If I was buying again I would pick up a manual GTB. I've modded my 3.0 as much as I can and I wan't to go further

[DRFVDR]

What have u done to the 3 , I bet u could do more

I have 3 bp legacy engines sitting on my bench which beg to differ. In the next few years they will be as common as the early ones.

Umm an o4 gt assuming its a BP doesnt have an ICV valve, they are drive by wire and use the throttle blade for idle control.

[DacerX]

yeah that by wire stuff is a bitch im trying to get my H6 motor just to work by cable but now the car maybe too damaged from the quake to go further, would keep an eye out there mite be some good stuff up for sale soon

Thats sucks, all our cars have been fine apart from one falling off the jack stands. Why did you go to cable over dbw? Dbw is great for antilag and rev match on downshift, ill be doing dbw on my next car.

[DacerX]

so u have all the gear to run that crap? i would have to get the older version of the extreme to do it and then get a new pedal box, u have to remember that im doing all this to a 22 year old car its not exactly easy

The older version of the extreme would be ideal or you can just get a dbw driver to run it on the new one. Then find a foot pedal from a bp legacy for cheap because they never break and are simple to install. If you saw the LINK chevett at 4'sn rotors he's running that setup with a GM 90mm tb that cost about 50$ from ebay.

[DacerX]

sounds alot more difficult than attacting a falcon throttle body on and attaching the cable. thats really all there is to it, and electonics are gay as, mechanical is where its at

[Guest]

Iv also got a cheap cable H6 throttle body if it doesnt work as planned. No idea if they fit the dbw manifolds tho.

[DacerX]

send it down and let me try if it does mite be keen, i have a falcon tb on now but we havent tested it all yet

Hmm not sure on the exact name of the valve. It was running lumpy as hell at idle. Valve was replaced and it was sweet after that.

My 3.0 has adjustables, sway bars, intake, exhaust. Really all I can do without spending stupid amounts of money is get a retune.
