These ford seals may or may not work with sertain valve springs, be sure to measure all Id/od before committing.

 

So I'm in process of figuring out why some of my seals are tore/smashed. Finding out that new style seals 03 and up may work on our 2nd gen. They are held in place by spring and can't come up from too much boost etc. I've spoken with https://ussealparts.com and they have both styles at great prices, although top hat style is listed for 03 and newer. The difference I believe is in ID where it slides over guide, sounds like top hat is slightly bigger but that should not affect the sealing capabilities as valve still same diameter. I ordered both styles and let ya all know. Now this place advertising them as they do fit.  https://puredieselpower.com/dodge-products/dodge-6b-cummins-intake-valve-seal-exhaust-valve-seal-set-b45962-b45963.html#/product/21380 

 

Another thing I might be doing is upgrading to better push rods, springs, trunion bearings and roker arm bridges from Manton. That may explain my ovaled guides and smashed seals, or so I hope.

Let me know your thoughts

Well so far my exhaust valve seals have held up with the green gold. When I did them I cleaned the mating surfaces good then put everything together. I let it sit overnight before I started it. I have to change out injectors this weekend so I will recheck them and the intake ones.

Keep us posted. My modified top hats seem to be holding up too, but I really need to put more miles on before I can say for sure.

So all looks good. They looked like I just put them on yesterday. I have around 10k miles on them. So far so good.

What are you pushing for boost, do you have an exhaust brake.

As far as boost goes I limited to about 50 52 cuz the head isn't o-ringed. Basically the reason why I got twins is so I can tow, but I like the power too. No exhaust brake don't need it for the 5r110 transmission that Ford has it basically will downshift when it's in tow haul mode. Now I have done some long extended runs on long straightaways and have hit 72 psi and backed off. But the head won't take much of that so I limit it.

Then it must be the exhaust brake that pushed my seals off hight enough to get bit up by retainers. Idk but still wish I had the head machined for top hat seals, the ones that are supposed to be used not the ones I used. I don't like the fact I have a small gap/cavity between top of guide and bottom of seal/lip. I believe that cavity will fill in with soot and contribute to more guide wear, for now I haven't used the exhaust brake much.

I think my issues were from high drive pressure. I mean this is the first time I have ever ran twins and  I was a powerstroke guy so it's all new to me

In your case it probably was high drive pressure, in mine the only logical thing I can think of is exhaust back pressure, that I heard can get in 70-80 range. I never seen anything more than 45psi, maybe 50 of boost for short bursts. 

Or I'm just hard on my truck and drive it like I stole it, which on a rare occasion I do. Still never had an issue till I had the head redone. I'd hate blaming a shop for this but in this case they could of at least told me that top hats was an option, I would of definitely spent extra 80 bucks to not deal with this. 

I was going to do the valve seals this weekend, but the stock & Hamilton springs do not fit over the bottom lip on the SS45933 (4 litre Ford v-6) (VC-292) The springs are .073 , seals are .079. Anybody need some Ford seals?

 

I used Manton pushrods conical springs, fit fine. So far no issues. 

It is an excellent idea for sure. Just don't need $450.00 springs to install a &1.00 seal.
