Help me out here folks.
Slowly we've been replacing the head and exhaust gaskets on our 1976 FJ40.
We're basically done except for a bunch of minor odds and ends we figured we'd do while in here. When we first pulled the vale cover off we came across something unexpected, the entire valve train is covered with a felt like (for lack of better term as we don't know what it is) material. Its cut to sort of fit in-between the rocker arms (I'll try to post a picture soon). When we heat cycled the engine for the first time after the gasket replacements we watch closely and noticed it seemed to help "soak" everything in oil.
However there is no mention of this material in the shop manual and we can't seem to find any information on it anywhere. Is it something that should be replaced/cleaned over time? If so what is it and where can we get it/how should it be cleaned?
Thanks!
