Thanks.
But it appears that #12 is an o-ring and #30 is a seal.
Do you use an o-ring and a seal on each side or do you use just two seals?

Oh, didn't see that part. As mentioned, as long as you didn't cross thread (check around the washer to make sure it's flat with your fingernail...) you shouldn't need new seals.

Just snug it up some and see what happens.

yeah if the seals are new then they won't be the problem. when they went in did they seem hard to turn or did they go in easily

Re: Tightening the banjo bolts in back of the heads.

I replaced mine on my '94 last month. Like Javier said, just get one of those combo 15m ratcheting wrenches and make sure they're tight first. If it continues to leak, try the washers. I did the complete swap from the old steam pipe/washer/hose assembly to a brand new one with the engine in place. Just reach back there and you'll find room with the ratchet wrench.

Looking at the diagram, what is the diffrence between #12 & #30?
What is the difference in the bolts #31 & 32?

Does anyone have the part numbers for all these parts:
12
30
31
32

Thanks.
12 and 30 are the same and 31 and 32 are the same. You will need 4 seals and two bolts.

Re: Tightening the banjo bolts in back of the heads.

Get a mechanics mirror so you can at least see where it is on the head and do'er.

Pulling the engine to do a couple of bolts at the back of the heads, that's F-ing hilarious!!!!! That's better than people a few years ago saying to pull your exhaust off to do plugs...........right!!!!

Wow, do I detect a hint of carcasm? Dropping the cradle might not be totally necessary but it takes all of maybe two hours to do.
