hardened valve seats for Unleaded fuel

[Boyscout]

When I had the engineering done to overhaul the engine, I took the opportunity to have hardened valve seats installed on the exhaust valves so I could run on unleaded fuel. Work was done by Alan Y Brink. Superb job. Been running on unleaded for more than a year now. Daily driver.

That is a great mod to do.

I will be doing this as well at some point in the not too distant future.

The last Caltex garage in our area has now also stopped selling LRP, so it is becoming more of a necessity.

What did the engineering work cost you Boyscout?

The entire head was redone. So strip, chemical clean, resurface (skim), new valve guides and stem seals, 4 x hardened seats installed, ground all valve seats and valves. re-assemble and leak test. It was around R2400. Work was done by Alan Y Brink.

Did you have to install new valves aswell for the unleaded conversion?

[Boyscout]

No, the existing valves were re-used. Cleaned and dressed.

What do you mean by dressed?
