- It's been a while, but I've been procrastinating.
In this video I show you some lathe work and some seriously ugly welding.
The Home made V twin finally saw the track and finished every race, albeit only mid pack although it felt a bit down on power. After further investigation It seems the head is still leaking, although only combustion gas and not oil thankfully.
Probably due to the 'squishy' base gasket.

Instead of viton o ring why not use a soft copper ring that has been softened and machine a simple groove on the head? Should provide plenty of squish and still seal up very well.
Worst case with the Viton is I use the same groove for a copper one if it fails. I don’t know if they’re readily available and I think I’ll have to make the copper one. But it’s definitely an option.
@@OddsandEndsMachining to make a copper ring simply wrap a piece of wire around a round object of the appropriate diameter then cut and but the ends together.
@@Engineerd3d thanks for that. I wasn’t sure if it needed to be joined 360 degrees. I was assuming it needed to be. That’s always another trick I can use later if needed.
the edits are 🔥
Waterjet cutting for the copper. An O-ring is not going to do anything your current head sealant material is doing already, as you already found out, its the paper gaskets that are causing you issues so removing that element will solve the majority of the problems.
It did cross my mind not to add the o ring and keep running the copper head gasket spray. I am still interested in running the Viton o ring, it’ll make an interesting video setting it up and machining the groove, otherwise I’ll just run the base spacer to start with.
Ferriday Engineering in the UK make copper head gaskets with a stainless steel fireseal ring for these engines
Interesting, the Viton o ring has held up for 2 race weekends now with no sign of failure. I’ll keep that in mind if I run into trouble.
I missed out the 3d printed part of the click bait
At the end I test fit it as a template for laser cutting.
All fingers crossed here.
I didn't notice the copper gasket being too far our that it couldn't be trimmed to fit - did I miss something?
The original copper one I made was a bad fit, I couldn’t be bothered making another one so o ring it is and it should be cheaper and seal at a lower head stud torque.
@@OddsandEndsMachining OK, consider this subscriber enlightened. Thanks for taking the time to reply!
