Front seal on 440 leak?

[Mark1972]

Yep, still a mystery why oil all over the front. Even bigger mystery why I can't make it leak more. I never heard any ticking of any sort. This is the second time this has happened. 2 years ago #4 cylinder exhaust valve push rod blew though the rocker as well. These rockers were all replaced when the engine was rebuilt in 2020. I've heard there has been problems with aftermarket stamped rockers for a while. Now I'm thinking about roller rockers, but don't know anything about them or setting them. I've heard they come with their own set of concerns.

I'm wondering if the oil that cylinder was sucking in due to the high vacuum all came from the cylinder or could it possibly have been sucking it through the head gasket?
Maybe a leak down test would be a good Idea.

I have some good rockers if you need a couple let me know.

I hope you didn’t replace your rocker arms back in 2020 with Elgin brand

I returned two sets back about five years ago , paper thin junk

And I run the Comp XE275 HL with steel stamped rockers on the street

Is there any oil under the intake manifold on top of the valley pan
