Any advice for ej novice intending to do the leaky hg on 2003 Fox 2.5 sohc I think it is?
Timing belts been done. What other parts required hg rocker gaskets? Intake and exhaust I'm sure
Any fiddly ones to order like an ea82 and its can box o rings
Genuine part numbers be handy too if you can. Any preferred trusted suppliers of after market?

Resurface the heads. GD has a good thread about DIY

Turbo Subaru gasket part number ending in 770

Valve cover, exhaust, intake gaskets - subaru or decent aftermarket.

Cam seals, crank seal, oil pump oring, i always use Subaru on these, but can't say if it matters.

Cam, crank, oil ring, and rear main definitely matter on brand, Subaru only. I like the 6star head gaskets, but they are expensive

6-Star is a ridiculous and insulting marketing ploy. They are just rebranded Cometic gaskets. They are not better in any way IMO than the Subaru 642/770.

The full Subaru Part Number for the Turbo Gasket is 11044AA770.  This is a Multi-Layer Steel gasket and is the preferred one for most non dealer shops they usually use what is specified/superseded by VIN number.


I used them on my EJ20 head installation and they work great!

Thanks for the info it will be helpful. Gotta say my local dealer uses genuine on ej with new bolts and not need retention. I have found same using quality genuine hg on me ea82s. Even though I check tension they never take any.
