Hi guys just about to change the oil seals on my zd30 non crd patrol was wondering if anyone has any objections to putting a little pressure resistant silicone on the outer diameter of the oil seal it looks like a preety shitty designed seal. I was also wondering to just change the oil seal I cant see any reason to pull the manifold, egr pipes, throttle body or rocker cover or am I missing something.

Thanks heaps any info would be appreciated.
