Pushrod Tube Seals, ..I know it's been asked to death Options

[stateofidleness]

Gents,
Getting back some "free" time to actually do some work to the car after about a year and a half, and am going to start by fixing the oil leak(s) the car has. I have removed the old heat exchangers as I will be putting on some stainless ones.

My current project is attempting to replace the pushrod tube seals. I know there are many threads, but I have a specific question regarding the 1.7L engines. I was reading that there may be an "early" bore size and a "late" bore size. So this has me a bit confused now, and I don't want to order new seals until I can confirm which ones I need.

Also, I'm a little confused on whether I need to do all that TDC stuff when removing all the rockers/valves. I've never messed with the valves before or done an adjustment (still a "noob"). I do plan to do a valve adjustment after everything is put back together, but wanted to know if I needed to do anything special during removal, or if I could just go to town on removing everything.

ps: anyone want to show a noob how to do a valve adjustment? I pay with beer (IMG:style_emoticons/default/smile.gif) (IMG:style_emoticons/default/beer.gif)

Thanks!

Just remove them. No need for tdc till you go back on with them. Rockers must go back on the same cylinder. Pushrods must go back in the same spot and same orientation. Same with lifters if you remove them.
