    I bought a very cheap 55 reg ldv with a duff headgasket. Usually it would be a no-brainer BUT....

    On looking at the hydraulic lifters they have some ovality to them, but also, one has fractured its collar, necessitating at least one replacement. I'd feel more comfortable just replacing them all to be honest and having a look on ebay its the CRD/VM 2.5 engine as found in london cabs/Jeeps/Chryslers etc so they're readily available...

    BUT!....

    Heres a used item:

    and Heres a new item:

    See that the new item doesnt have a collar fitted to keep the two parts connected in the event of an internal valve conquest!?! It looks to be a pressed on item, Unless theres a set supplied with them and they just snap-fit on...? They looka a little different but thats a common theme with the different suppliers I've found.

    I've tried emailing the sellers of these items and no respone!

    Anyone familiar? Opinions?

    What's an internal valve conquest ? How can the parts separate when they are held in by the camshaft and rocker under tension ? If the valve has lifted high enough for the lifter to separate I think you are going to have bigger problems than the tappet to worry about, the valves will have gone through the piston tops.

    An internal valve conquest is where they leave their guides to conquer lands atop the piston lol.

    You're correct, but the lifter I mentioned that has split its collar has obviously suffered some pressure problem meaning the top collar has split. There is zero contact with the piston tops, the rocker arms are all within 0.05mm of each other so they haven't caused or suffered any damage either.

    Its a strange one, as in my mind, like you say the lifters shouldnt need collars, they're held together under a rocker, nested into place. But why are they there!!!
