Some parts too look at (Valvetrain)

[tejohnson]

Well, it would appear I might have found a workable solution for these specific heads. Since it is a 8mm OD valve stem, and .514 OD valve guide, the Fel-Pro seals with the part number SS70710 should do the trick. The package includes 12 seals ranging from $20-$25 depending on the store. RockAuto.com says they are for the following applications:

Quite a few. Below are some comparisons with the Intake seal (93734) from the part number SS72685 (Intake being the seals that I had no issues with).







Old on top of new to eyeball the difference:



The measurements (while not attempting to expand the rubber):
Top ID: .275
Bottom ID: .500

This seal has the same amount of depth and contact as the old. I went this route simply due to efficiency. I could have bought two packages of the SS72685 and only used the intake seals (93734) which means ~18.00 wasted, unless you could sell the others. The part number 93734 appears to be discontinued, and you will not likely find them individually.


Any thoughts?

Interesting indeed. I'll check mine out when I get home.

[tejohnson]

The intake valves are 1.76", and the heads have D shaped ports. The part # that is cast in the front of each head (over the plug holes) is: 10218170

EDIT: Interesting Google results: http://www.pera.org/articles/eb120220.htm

Ok, so... does it matter if they are 3100 or 3400 heads for the year split? If they are 99 3100 heads, there is a good chance they are different from 99 3400 heads. I know the castings are different -> http://60degreev6.com/forum/showthread.php?t=25040

I didn't word that right. I'm asking specifically about the valve stem and seal combination. I know the ≤99 and ≥00 3100 heads are different. But ≤99 and ≥00 3400 heads will all work with the 2.2 seals, right? There was no change on the 3400...

Sorry, but did you guys read above? The problem is that they are 1999 heads (that is, unless they were switched long ago when I had them ported and polished). [perhaps that was my first question, am I mis-identifing these heads? What is the OD of the valve guides on 2000+ 3400 heads?]

The OD of the valve guide is .512 for both the intake and exhaust. I did get the 3.1 MPFI seals (Felpro Part Number: SS72685), however, it appears the exhaust seals (70819) are too big. Given the identical sizes of the exhaust and intake guides at .512, the intake seals (93734) should be perfect. I just don't know if that is the same seal that is in the 2.2 cavi seal kit. Will be making a trip to NAPA here in the very near future.

[Canyonero]

Can you also use the 2.2 Cavi seals on the '99 and older? Does it matter with the 3400 vs. the 3100. I was under the impression that the '96-'03 3400s were all the same.

I got the 2.2 seals for mine, which is a '98 3400. Will I have these problems? (I have not assembled them yet)

[Superdave]

Well it looks like you bought old 3.1 mpfi seals, and I don't know of those heads have the same stem diameter but if the seals are different aparently not. I used Dodge seals on my 05 3500 and didn't have any issues. The two intake exhaust stems are the same diameter as each other 99 or 2000+ they are just different sizes between the years. I'm not sure which set of seals should be used on 99 and older heads.

iirc 99 and older heads can use the 3.1 MPFI seals, 00+ heads need the 2.2 cavy seals or the Dodge seals i guess...

Digging up an aged thread. While starting on my heads to clean them up for selling, I noticed something that irritated me a tad:




Notice anything odd? The seals that I installed are the felpro "viton" seals (SS72685). Exhaust - 70819 (left)
Intake - 93734 (right)




Here is a bit of a closer pic:



Below are pics of the intake and exhaust guides:
Valve guide OD - .512
Valve stem OD - .312
Measurements for above is for both intake and exhaust. Notice the "step" in the guides. Perhaps these are not 99 heads? I did send them off long ago for P&P, maybe I got a set to 2000+ back?





Pic of an exhaust seal that cam off the guide, spring still on. No way did the springs move to "lift" the seal off the guide. Only 1 exhaust seal did not come off, and all the intake seals were just fine.



If they really are 99 heads, given the valve guide OD on both intake and exhaust being the same, why the different seals for intake and exhaust?

[tejohnson]

Funny... I just viewed my above posts in Internet Explorer and my posts above look like crap.

Looks just fine in Mozilla... That's what I get for using HTML in my posts...

[tejohnson]

Well... Decided to fix the "hanging" shims. Made a little tool to pull the seals back off without damaging them (I'm so proud):
