erik litchy Posted June 1, 2008 Share Posted June 1, 2008 ok i have a new seal ready to go in (obviously not pictured) but i need to know the monting depth. damn do i ever wish i had the factory tool for this. i had it set deeper but it moved on me... it wasnt crooked like that. (theres also a speedy sleeve that made no diffrence.) Link to comment Share on other sites More sharing options...
Turbone Posted June 1, 2008 Share Posted June 1, 2008 The main seal usually goes in easily, thats probably why its just a tad to far in. Its ok, but I would try (carefully) to even it up. Link to comment Share on other sites More sharing options...

GeneralDisorder Posted June 1, 2008 Share Posted June 1, 2008 It shouldn't be in that far. Even, and flush with the OD of the case. Use locktite blue (the 248 stick works best) on the OD of the seal. A tiny bit of valve sealant or grease on the ID. Use only OEM seals - they fit better. GD Link to comment Share on other sites More sharing options...
Turbone Posted June 1, 2008 Share Posted June 1, 2008 If its been like that for a while, its no good any more. Link to comment Share on other sites More sharing options...

GD will do. used the last of my loctite blue on her. Link to comment Share on other sites More sharing options...

Gloyale Posted June 1, 2008 Share Posted June 1, 2008 Positive it's not leaking form the oil pump??? Other than that, did you get the crank turned to fit that sleeve on it??? If not, you're diameter is increased and the seal may not be fitting right. Also it looks like I can see a bit of a bend in the edge of that sleeve. Could that be nicking or damaging the the seal as you install it??? Link to comment Share on other sites More sharing options...
nipper Posted June 2, 2008 Share Posted June 2, 2008 Have you replaced the pcv valve recently? Also if you can get a pair of calipers on there, check to make sure that there is not a groove worn in the shaft where the seal sits. It happens sometimes and requires technique to get it right. Where are you getting the seals from? nipper Link to comment Share on other sites More sharing options...

Could that be nicking or damaging the the seal as you install it??? that part is where the ring of metal was torn off the sleve. the seal rides just behind that area. im positive the increased diameter (overall within tolerances) would perhaps cause slightly more wear and a tighter fit.

Unless that shim is thinner than .07 mm (.00025 in) it has increased the size of the crank to larger than it should be. Which puts the skirt of the seal at a funky angle. That would be the thickness of paper so I doubt that you are still within tolerances. I've never seen one of those sleeves needed on a EA82. Only ever on old Iron v8s. I don't know if it's possible to remove it, but I would. Then clean the crank with emery cloth real good and install a new seal with locktite.
