ebinmaine 72,609 #1 Posted August 9, 2021 1968 model year HH100. Looking at the inside of the breather there are a couple of tiny little pin holes. Am I correct in thinking those go to the upward side as installed? Also, should I put a skim coat of silicone on that gasket or no? Share this post Link to post Share on other sites
Stepney 2,354 #2 Posted August 9, 2021 If nobody else gets back I'll check for my old teccy service book. May be in there. I thought the little holes went down for oil to drain, and it had a little reed valve to control the vent.. 1 Share this post Link to post Share on other sites
Howie 899 #3 Posted August 10, 2021 I think the holes go down, lets the breather drain. 1 Share this post Link to post Share on other sites

I wish you and I lived closer to one another as I have an HH100 I would give you for spare parts. I’ve got it on marketplace for next to nothing and haven’t heard a peep from anyone interested. It has a bad coil and they’re hard to find and more than I want to spend. 1 Share this post Link to post Share on other sites

If you do a search on YouTube there's a way that you can use some sort of sensor.. maybe a Ford brake sensor if I remember right? That sensor catches or creates the signal anyway. Wired in with a GM 4 pin module that does the electric work. Share this post Link to post Share on other sites

Thanks Eric , I saw some of that info but the engine had blown head gaskets one more than one occasion according to prior owner. I have just completed a Predator 301 cc swap into it. I’m not a purist for the most part and want reliability. 1 Share this post Link to post Share on other sites
