G'day,
As promised I've taken some photos of the three different seals for this area and put them in an album:
http://www.gmcmhphotos.com/photos/showgallery.php?cat=6677
I have NOT installed one of the PH O-rings and tested it to make sure it didn't leak, however, the o-ring was sized by a Parker
Hannifin applications engineer and he said it met all the criteria to seal properly.
Along with the PH O-ring I also tried a Quad ring; however, the crush wasn't sufficient.
Regards,
Rob M.

So, where can we get the Parker Hannifin O-ring P/N 2-230? Available at most Auto parts stores? or special order from ?????

Larry,
I wouldn't buy any just yet; allow let me install one to make sure it doesn't leak; not that I don't trust the PH Applications
Engineer. ;-)
I left out one part of the story, I had to buy the test sizes and have returned them for credit. The company I bought them from is
going to send me as many PH 2-230 O-rings that the credit will cover. If the one I install in Double Trouble doesn't leak I'll be
bringing a bunch of them to the GMCMI Convention in Chippewa Falls later this month; I've earmarked a couple for you.
Before anyone asks - NO I'm not interested in doing a group buy, however, once I've verified that they don't leak I'll provide the
company I purchased them from here in Houston and I'm sure they'll be happy to sell a bunch to anyone that IS interested in doing a
group by. They have a $10.00 minimum order.

Rob M.

Kerry,
The photos are to small to see the shape of the Dorman seal it is actually an octagonal rectangle. HUH? You say!
It is rectangular in as much as when it is in the groove the vertical part is greater than the horizontal part. It is octagonal
because all four corners are not 90° they are cut at an angle.
The PH seal is actually Viton not Silicone, however, that too will outlast us all!
I installed the Dorman seal last year and it traveled about 5000 miles without leaking so if anyone has installed one I would not
take it out.
The PH seal was sized as per O-ring design practices that's the only reason I like it better.
Now watch the damn thing will leak when I install it! ;-)
I was disappointed when the Quad Ring didn't have enough crush as they are really cool, I was told MANY years ago that the greater
the pressure the better they seal.

Rob M.

Nice job Rob! Admittedly, the Doorman seal is square and the PH is round, but since both have room to expand within the groove and
both achieve metal to metal contact, why do you believe the PH is a better choice? They are both silicone and should last
forever...or forever enough for me. :lol:
I'm looking for a reason that would motivate me to remove the Dorman seal I just put on.

Hey Bob. Nice work. In my opinion, it is clear by the pictures (crush and expansion) that both solutions will be quite successful. I highly suspect the Parker Solution to be less costly per ring than the Dorman. As far as someone with a non-leaking application goes: I can't see why they should create a job for themself to change out the ring as a special project. My Dorman application is sealing very nicely and I don't see myself changing it out until there is a problem. (Hey I have 2 spare rings now ;>) ) I would however, change out the ring if there was an oil filter ring during one of the regular oil changes because it is so easy.
With minimum order requirements as they are, The best distribution of the Parker rings (or for the Dorman rings to sell one at a time for that matter) is through the excellent supplier system we currently have in place. This is one more product that they can use to stay in business. (They would already know this of course) They are probably just waiting for you to confirm success. Hell anybody who would order the ring will also order other parts at the same time.
The suppliers could also co-number the ring to the GM original part number to keep things simple too.
Cheers!

John,
Thanks, this is the kind of stuff that anally retentive perfectionists do! ;-)
I have not given up on getting a blue print of the GM OEM part number for the seal as listed in the Parts Book 78Z.
It's called out in Parts Book 78Z / Engine / Section 8.012
P/N 6436950 - GASKET - adapter to mounting casting
I can't believe none of the ex GM guys don't know someone that could hook them up with the drawing or at least the dimensions and
materials.

Rob M.
