2000 grand marquis ls with handling package, magnaflow mufflers,dual exhaust, 3.55 rear axle
I am still formulating a plan of attack on my 2002 grand marquis lse with the noise in the valve train. It looks like quite a job to get the valve covers and front cover off the engine, so I think I should go ahead and change the timing chain, guides, and tensioners while it is apart. I am thinking of changing all the valve lash adjusters too and I assume I need to do that one at a time so that the rocker arm goes back on the same cam lobe it came from. Is that correct? I also thought about changing all the rocker arms too but Is it a bad idea to change all the rocker arms without changing the cams? Even if the cams look ok I assume there will be some wear and I am not sure how that would work with new rocker arms with no wear. Any advice would be appreciated.
