about 100K on it...
pulled valve cover replaced bad
lash adjuster, put rocker back on, very loose. thus exhaust valve not
closing and reason for low comp. only 2 thoughts on why not closing were
carbon wedged in it, or seat came out...
do I need to
pull timingcover and all the chains? or can I manage to just unbolt and
remove head and chain and have any hope of geting chain back on
after?
never worked on a 4.7 crazy OHC
stuff!
not alot of room to wrk in there
either.
Thanks!!!
Tony.
