    Mine looked similar, not as bad. I took mine apart for a head gasket, replaced it and have had no issues since. Not much help, but wanted to say you are not the only one.

    Guys I am just stumped. Is it the wrong guide for this head? I see they had two part numbers.420236500 and 420236501.
    Anybody know as I can feel it just doesn't slide in and out correctly and the whole head is on correct. It is a Slow 91 hear with a NEW chain and a RR tensioner.

    Austin....420236501 replaces 420236500. Same part, simply replace it. About $11. Loosen the tensioner first, then slid in the guide, tighten tensioner.

    I kind of figured it Superseded, and yes I install them as you mention, but they are tight as heck. It bothers me as what this one looks like. Never seen this before. Normally there's a little resistance and then is just sits in place.
    So you think just install a new one and go?

    The guide looses it shape (warps) over time from heat and as such, removing it then re-inserting it can and does become difficult. A new guide will slid in much easier. Yes, buy a new guide, install, done!

    Yes that happens to older guides. I like the ones where some goof puts em in wrong and it eats the thing to pieces.
