440 head noise. Perpetual problems. Problem solved

So the only thing I can think that has changed is that I put about a half a big bottle of Marvins mystery oil and some **** called rkr in it. Could the oil be to thin? Should I drain about half of it out and put in some thick oil?


Ummmm why did you do that???

If you had the valve cover off, you should be able to tell us what rocker arms you have.

Whiskey
Tango
Hotel???

How do we know if you don't have an adjuster that backed off. Maybe you bent a pushrods? Or that oil additive you used knocked loose some garbage and its bitching with a lifter.


BTW, you say perpetual issues. WTH else is wrong??
