New Part # for Valve Springs?

[keatsdude]

Hello folks,

I'm rebuilding my EJ22T with all stock components. I had intended to just replace head gaskets, valve seals, springs, and get deltacams.

Pulled the motor, found a lot of slop in the crank. Split the case, sure enough thrust bearing was toast and scored the crank. So I got ACL bearings and a new subaru crank, built the shortblock.

Today I'm installing new valve seals and springs, and have come across a little discrepancy. The Legacy Parts Catalog lists two part numbers for valve springs:

13217AA080 for '93-'94 and 13217AA060 for '90-'92 (Mines a '91)

So I'm ordering parts from SGP.com, and they say "New Part # 13217AA080" When I search for 13217AA060.

No big deal, I order the "New Part # -AA080 instead of AA060. My dilema arises today - The new spring is about a quarter inch shorter than the old ones.

I think I'm going to use the "new" shorter springs anyway, just figured I'd see if anyone has ran into this before and had any info.

Thanks!

If you do use the shorter springs you need to check installed spring pressure to see if it in spec. If not you might float your valves at higher rpm's especially with the delta cams with a higher lift.

I did see the spec for the spring pressure in the FSM, but didn't have an accurate way to measure it.

I talked with a knowledgeable parts guy at the local stealership today, and he said the new part number supersedes all the older models springs. He said run the new "shorter" springs and don't worry. I did check the free standing height, and it is indeed shorter than called for, but the manual is for a '92 and the new part # spring is spec'd for '93-'94...

Anyway, I'm going with the new shorter AA060. If anyone has had problems with the new springs please let me know soon! Hah!

Ok, I just looked in the parts book and the valve spring & valve retainer changed for the 93 model year. All the parts supercede up to the new parts, but if I were you I would run the new valve spring retainers with the new springs. I don't know if the old retainers are different, but they may be.

Old Valve Spring Part #: 13217AA060
New Valve Spring Part #: 13217AA080

Old Valve Spring Retainer Part #: 13209AA030
New Valve Spring Retainer Part #: 13209AA060

Thanks for the reply Josh...I went ahead and installed the new springs with the old retainers just a few days before you shared that. They seemed to fit well together, we'll see if there happens to be an issue with the valves I'll start there. I should be able to fire it up in the next few days.

Ok, keep us posted.
