Tappet blocks seeping
I saw a seep on my tappet blocks and thought I had to replace my pushrod cover O rings but when I took it apart the O rings looked fine and I couldn't find a crack in the tappet block.
What else could cause a seep there?

Base Gaskets, Tappet block gaskets....did you replace the O Rings? They can look fine but still leak. The cracks are very hard to see and when you see one you won't believe it could cause a leak.

The seep seems to have gotten worse when I put in Amsoil 20w-50 so I am going to try dino 50 weight and see what happens.
I put in the amsoil to combat the heat we have down here but not sure it is a good thing.
If it still leaks after the 50 weight then I will change the o rings.
I didn't know about the micro crack thing on the O rings.
Thanks for your reply spanners.

No I didn't replace the O rings yet.

The manual says to go to a heavier oil as the ambient temp goes up so I was going to try it and see.
I looked as hard as I could with a flashlight but I couldn't see any evidence of cracking in the tappet blocks (with the pushrods in place).

Before the Amsoil I had Castrol 20w-50 in there.

I'll let it seep.
When it starts leaking then I will replace the lifter blocks.
Yeah I know I'm kinda cheap.

THC, shot in the dark but once upon a time I "overcharged" my K&N and it started dropping. There was no sign at the air cleaner cover but gathered nicely at the tappet blocks and appeared to be a massive leak from there. It was revealed to me that it was the air cleaner once I took the cover off. Don't mean to sound like a total idiot but maybe check behind the air cleaner cover...see if there's oil. Good luck
