removing the camshafts on v6 to access the hydraulic lifters
Posted: Sat Jun 14, 2008 10:13 am
hi all,
i`m busy on here today!!finally,i have decided to remove the rocker covers on my noisy/tappetty v6 to see what`s what.i`m hoping there`ll be no/minimal camshaft wear,and that maybe i have one or more sticking/bugered hydraulic lifters.whatever the condition of the camshafts,i fully intend to remove all the lifters and dismantle/clean/replace them as needed.
however,although i have all the tools i`m likely to need,i`m a bit unsure about the camshaft removal.obviuosly i`m going to disturb the timing belt,and therefore the timing.i see no fact sheets on replacing the v6 timing belt,which is probably a much bigger job than the diesel.if i had a manual,i`d be fine,but tackling it without scares me somewhat,i case i get something wrong and wreck the engine when re-starting.is the timing belt moveable,so i can simply move it and remove the beltor does it have to be undone to give the belt some slack to remove/replace?ideally i won`t remove the belt anyway,but need it exactly as it was.where are the timing marks?on each camshaft to align with each other,or on each camshaft to align with somewhere on the engine?do i turn the engine over to check alignment,on the crankshaft pulley,when i`ve done?how to i check top dead centre on a v6,and which is piston number one?
you see,i`m a bit in the dark on the v6.i`m meant to be at the bash next weekend,and don`t want to get halfway through and not be able to get it back together in time!
many thanks
