when replacing these two leaking oil seals with new ones i heard you can off set them a little bit so they're not sitting in the scuff marks left on the crack/camshaft made by the old seals. this marking the new seals less prone to leak is this right!

Crack seals! It must have done some serious kms to have left a mark

I've seen bigger seal grooves left on crack and camshafts on vehicles with less than half those k's

You mean crank! Yes you can offset them. In the way of seeing where it has been sitting. Then when you hit the new one in. Make it go in a wee bit further or a wee bit less. So the lip is slightly in a diff place to run on a fresh seal surface.

you can pull the seal out and see if saco have one thet is slight shorter also dontdamage the crank when you remove the seal or you be having worse issues then a groove to worry about. I got some special seal pullers finaly from partsmaster for thet job to whack a hole and pull em still tricky but not as mutch as without them special cork screw type tools.

interesting enough the seals i did get from skf seals and bearing were just that. i was able to hit them both all the way home giving the seals a new home to run over. no more leaks and a dry oil free new timing belt!

I agree. I've done a lot, and have very rarely seen any significant groove worn in. Especially at low k's. A couple that have been up around the 3-400k range you can sometimes see a groove.

like the little daihatsu 3cylinder i just striped down just 2-3 weeks ago clock was close on 180,000bottom crank was passible but the end of your fingernail would disappear into the groove when you ran your finger over the camshaft and it was evident oil was pooling out between seal and cam.is this a result of smaller motors having to work extra hard buggerd if i know.
