Pulled my valvecover today to check on my rockers n what i saw was horriffic. On the top of the V/c there was basically snot like stuff on it, and it covered the whole inside. My neighbor which owns a mechanic shop told me to take and do a compression test on all cylinders. here are the numbers
1-135
2-115
3-95
4-110
5-90
6-90
7-100
8-80
He told me either a cracked head or bad head gasket or intake gasket. Tell me what you boys think

Check/reset valve lash and repeat. If it still does it, check the valve seat for any signs of damage, or excessive wear.

If the valve seats need to be checked, yes. To check, or set the lash it's just the valvecovers.
