Don‘t forget to replace the valve cover rubber gasket. Order them beforehand.
Dominik,
Did you ever find a GMC to buy?
The GM 6.0 was one of their most robust engines (probably why the discontinued it). The only thing Larry could do under the cylinder head covers might be the valve guide seals. But in this engine series, he is more likely to loose a coil pack. If I remember correctly, there is also enough top FEAD on the engine to make removing the head covers a real bear AND (depending on the assembly plant - there were 2), it could have formed in place gaskets. Those are famous for leaking if not applied on automated line at St.Katherines (PO).
If it is just being noisy, Larry is better off just turning the radio up.
