This is amazing. Been looking for something like this for weeks now. Finally found it! Though, unfortunately, I can't see the photos on the first page of this post.

What is that gasket?

[tenzhushoten]

Very useful info. I bought a 2005 STi recently. It's running smooth. A friend of mine has blown engine in its STI. He wants to sell it to me. I'm thinking for buying it and rebuilding the engine. Thanks bro !

Thread deserves a sticky. And new pics!

If anyone can fill in any of the blanks. I'm not 100% sure what everything is. I might have gotten rid of some of these o-rings when I swapped for aftermarket parts... or I left a part intact during the rebuild and didn't find that gasket...

Anyway. I hope this helps someone sometime. Have pictures I'll try to add too.

timing chain covers.They have no dimentions or valid descriptions. They either have obvious spots or don't. I've
used RTV for the wishy washy areas before.

Shew!

Quite the list you have there. I was thinking about a build similar to this one!

[BuiltSubaru]

Curious to know whether or not you are going through with this?

[fire911]

How did it turn out?
Any stats of power?

[sub2010ss]

Is it just me or are the pictures mia for everyone?

[1fstSTi]

anybody have the part # for those half moon plugs that goes on the side of the heads?

What year? What do they go to?

[1fstSTi]

2005 JDM STi. It goes on the corner of the head, below the valve cover.

[omg3hdpk]

master gasket set and it had a factory seal. The last one I got had been pilfered. I'd ordered it from out of town and had a bear of a time ID-ing all the orings that I was missing.

And the odd, pointed on one side, flat on the other, thick black o-ring is for the yellow oil fill cap.




These are the 3 (of 4) black, shaped o-rings and the larger orange o-ring that go between the two block halves. When these are missing from a set, it can really hamper your day. The 4th black shaped o-ring of the same size goes behind the oil pump. There is a very similarly shaped black o-ring ( the different one in the middle here) that goes between the block and the oil pickup tube so squint a bit when you decide what is what:



Rear main seals. They give us 3. I think because they have no idea how to write instructions. The rear main seal DOES NOT GET DRIVEN ALL THE WAY IN. I got even better at pulling my motor because I did not know that the first time. Fortunately my DP was kind enough to send a smoke signal. "...you.... are... a... retard..." it seemed to say. The rear main should sit basicly flush with the block. Subaru "mechanics" use a tool. ( <--- that should be a t-shirt)
