Zetor 6340 engine oil leak

[KevZetor6211]

Hi, I’ve noticed some oil in the side of the tractors engine after about 30 mins work, don’t know where its coming from, I’ll attach a photo. 2006 Zetor 6340

Looks like it's the breather plate the oil filler is attached to. My 7045 was the same, try using some Hylomar or Permatex on the gasket.

I think its only a old O-ring rubber seal - just change it to a new one, best will be MVQ instead of the original NBR material.
