Hello - I'm obviously new to the forum. I've been reading a lot and this seems to be a great forum for KJ owners. Glad to be here.
So, I have what I believe to be a dropped valve seat in my 2002 liberty limited 3.7l. The frost plug on the rear of the passenger head sprung a leak and I overheated badly. The engine still ran after I let it cool down but made a severe clattering noise so i shut it off immediately. I ran a compression test and I have good compression in 7 cylinders and 0 in the rearmost cylinder on driver side. So great, I have to pull both heads, one to replace head and one to replace frost plug. Hopefully I won't find anything more catastrophic when I pull the head.
I have read and read, including the FSM several times. My question is, why do I have to remove the timing cover to remove the head? Why can't I just use the wedge tool to hold the timing chain and then remove the camshaft sprocket and then remove the head? Is there something here I am missing?
Thanks,
Bob
