Oil Passage Blocked ? Or IS IT !!!!!

The gasket imprinted or sank into the oil passage galley and could have been restricting oil flow.
Couldn't really see any top end damage. The cam bearings were within spec at .032 to .038 and the cams measured out ok with no loss of lobe material, shims and buckets were ok.
There must have been adequate oil or just dumb luck.
Should the gasket be put on as it is sold? or should the gasket be cut to open flow?
My thought is it should not be trimmed or the gasket would come that way?
Thanks, Spencer

I just wonder if cut, will it cause a leak on the back side?
The way it sunk into galley really bothers me though.

BBBUTTT looking at your gasket it should not be pushed down blocking the oil hole so good thing you caught it in time.
The first item to suffer would be your camshaft bearings, if they are ok (no scuffing on the bearing surface) everything else should be ok.
Just looking on the edges of your gasket it looks like your gasket is wrinkled??? what compound are you using to cause that?? normally the gasket does not drop into the cavity. I suspect you need to look at the compound that "melted" your gasket.

I put it on dry with no chemicals and don't use any additives in my oil.
I use Rotella 15w-40.
When I pulled the cylinder, the gasket stayed with the top case and it had no wrinkles.....and took 2 to 3 hours to get off......... :blink:
Really don't know what to think, but thanks for responding.

80B4, have you seen the gasket droop into the galley that way before?
Thanks

As stated before I did have a known brand base gasket which just started falling apart, so I had to remove the barrel/ head extra to fit a new one (I used a genuine gasket this time - dry) and it appears ok (I won't know till it goes apart next time?).
Lately I have been concerned about the quality of gaskets supplied because my friend also had his gaskets wrinkle up and appear to swell, is there something in the new oils?, I don't know maybe someone out there might have an answer.
