Anyone here ever done it? I'm replacing the guides in my 200x and I'm trying to decide whether or not its something I want to mess with or just take it to the machine shop.

take it to a machine shop. they have to be pressed out and then in. then they have to be reemed to fit the valves.

Valve guide suck to do! In all my years of rebuilding/ building engines. I have rarely ever seen vavle guides worn so bad they needed to be replaced.

do some measuring with a good bore mic and see how far they have worn. if within spec, just change the seals.

I had an exhaust guide worn out on my 200x. I checked it by the amount of free play the valve had in the guide. If you don't have an idea of how snug a valve should be it's best to take it to a machinest. I work in a machine shop and we didn't have any split balls that small. If you could find one, that would be thembest way to check.

i done a 200S several years ago. i cleaned the head so that there was no oil residue on it and put it in the wife's oven. i can't remember how hot i got it. then with welders gloves took it out and they just tapped out and the new ones pressed in nice.

I have done a few, head in the oven, then freeze the guide with spray, taps right out, same going in, head in the oven, guide in the freezer. But after its in, its best to ream the guide for the actual valve stem.

What about leaving the old valve guides and installing new valves? The exhaust valve on my 200x was shot. There was not much play in the guides before I took them out. Would it be ok to just install the new valves, or should I do the guides since I am already there? Sorry, I don't mean to hijack the thread from Mullet_Boy, but the topic is perfect timing. What about seating issues? I guess i will find out when I get the new valves, but should I expect the valves to not seat good? (I can't imagine them being any worse than they were with all the crud on there). : )

The head in question has a lot of hours on it. I don't have the tools to measure the id of the guide, but the new valves i bought seem awfully wiggly in the old guides. So i figured I'd replace them while its apart. I'd read a bunch about just doing the oven trick and that sounds easy enough. I guess my new question is with a brand new honda valve and brand new honda guide do i have to ream still? Thanks guys!

I would put the new guide in, and see if the wiggle factor with the new valve gets better, might just be good to go. worst case is you would then just have to bring it in to get it reamed.

Thats kinda what i was thinking. I have to take it in to get a valve job done anyway, just have them check the clearance while its in.
