SVO double valve springs eating up my valve stem seat!! Any ideas?
EDIT: that is supposed to say valve stem seal not seat sorry....seats are fine
I have a set of the SVO double valve springs on a set of worked E7 heads on a 5.0 engine and I notice the motor smoked some on intial startup....well I found the valve stems seal destroyed on most all the valves....I think they are getting caught by the springs and then they start letting oil in of course... Is there a specfic seal to use with this springs? These seals are the blue type with a little metal cage around it. Let me know....I thought this motor has rings goin bad or somthing but turns out its just this problem!! Thanks

They should be the good positive viton seals all around (like found on aftermarket aluminum heads). Not sure on diameter, but it should not be difficult to find what you need. Cheap umbrella seals will probably not last.

This is another motor I have had for awhile thinking about putting it into my new black LX hatch...trust me these E7s aren't your typical set....they got big valves, ported. The springs/retainers are correct and the motor ran great just had that bit of smoke at start-up that I traced down to the stem seals.

It probably has the wrong seat hight, if is hitting the seal, means the retainer is hitting the valve seal, meaning the valve spring hight is wrong for the cam if it is aftermarket. Check inot that.

Just a E-cam Joe....
the retainers aren't hitting the seals, the inner spring is snagging the seal and moving it up down and some are torn or broke... I think I just need seals with a smaller outer diameter...? |

That cam does not need double spring, unles the inside is a dampner, looks like a spring inside.
