Look normal?
Cleaned up the engine to get ready for my Z head. Does everything look okay? I've never had my engine's head off before. Looks like some overhauled the engine at least before I got it.

Re: Look normal?
Looks like new pistons in old bores. By "old bores", I mean they do not look freshly honed as you would expect to see with new pistons. Do they look like new because you cleaned them up so well, or did they look like this when you removed the head? Have you ever run this engine?

Re: Look normal?
Looks pretty good. Don't forget to clean out all the head bolt holes with a bottoming tap and air real good before assembly.

Re: Look normal?
Yea, I've ran this engine as long as I've had the T, about 7 months. Here's some pics of what it looked like when I took the head off.Jerry VanOoteghem wrote: ↑Sun Oct 10, 2021 7:20 pmLooks like new pistons in old bores.

Re: Look normal?
You also have replacement one piece valves, so someone has definitely been in there before you. It looks good to go.
The tap size for the head bolt holes is 7/16" UNC.

Re: Look normal?
I just did mine today. I started with a standard tap, followed by a bottoming tap, then a 7/16 bronze bore brush. The bore brush got a noticeable of carbon even after the taps.JBog wrote: ↑Sun Oct 10, 2021 8:06 pmThanks! What size bottoming tap?Mark Chaffin wrote: ↑Sun Oct 10, 2021 7:41 pmLooks pretty good.

Re: Look normal?
Just using a bottoming tap will not clean out the compacted carbon and guck at the bottom. The tap will do a great job of compacting it even more. I use a drill smaller than the diameter of the hole and gently break up what is in the bottom. Don't force it, or you will need to seal the bolt threads when you go through the bottom of the hole into the water jacket. Done both by hand or with drill motor running slow. Then vacuum out the leavings.
I know the voices aren't real but damn they have some good ideas!
