Its a brand new gauge ( although cheap)
Cleaned the strainer already.

Forgot to mention the low oil light isnt actually on , it seems like a very small amount getting to head , and the new tappets ( and old ones ) are noisy.

When the old tappets started ticking i got the head done , havent drove about with it rattling.

Also still have a hard time starting it when its cold , all good when you lift the flap under metering head.
Cheers.
