Here's a few pic's

A couple of lifters. (the one is badly worn , but the other is more normal on a normal milage engine)
So a flat lifter is teoreticaly worn , but in reallife these lifter still work fine for many miles still.

Pic's of WBc cams. they more or less look like this , so i aume there is an cam/lifter issue on the WBX

I have torn a few down, have yet too see any stock cams look remotely like that, might relate to what oil is used or perhaps even a particular run of cam blanks.

The cam/lifters out of my 88 MV looked reusable as-is, at >270K miles.
The cam had virtually NO wear, still had machining marks visible on lobes.
(Second owner, 1st owner always ran Mobil1, I ran Rotella-T syn)

Well this cam was of the worst.
But all i have torn down shows sign of pitting.
but i also suspect lack of oilchange/quality oil on these.
270K?? without wear? thats amazing!

Been thinking about this... could be to do with the very cold weather you have... oil isnt flowing properly, cam picks up slightly before film strength reached??
Or do people run very thin oil in winter? if it was thrashed down a motorway.. that could also be the cause.. even in really cold weather the oil could get too thin on a run...

Dunno... what do you tthink?

I have missed out alot here THANKS for all the info it is really helpfull for me
I have also stripped the busses 2.1 that I built in 1994 and also had done about 250K Km and the cam also had very little wear
I used to service the WBX regularly with CASTROL FUTRON even the block does not need lign bore and just bought new std pistons and Honed the barrels

So then I also need to machine the oil groove in the T4 lifters for better oiling on the others

The SCAT Unitech rods are they better than the stock 2.1 rods
