OK. So I was finally able to get a look into the motor this morning and as far as I can tell the R.H. intake valve guide seal has popped off. I see at the same time a posting of an old thread about valve guide seal renewal without removing the head but all the pictures for special tools are all missing. AAAArrrrrgggghhh! Anyway, I really don't want to pull the head if I don't have to so I will probably try to figure this out. Also as these are the so called "better seals" I have read that they are problematic for popping off as they grip the valves too firmly. I don't want to keep doing this. Has anyone tried using them with the spring removed? On a related note, I have noticed that one exhaust valve keeper has split in two right down the middle basically creating a 3 piece keeper arrangement on that valve. As I never go anywhere near redline does anyone see any issues here with leaving it as is?
