well this is a tech type question, but its about rocker arms so i figured it should go here.
shes back [img]smile.gif[/img] runnin on all 6-cylinders. still getting a SES code, but i figure thats from the fact i havent reset the ECM in a while. anyway -- my q:
today i went to replace a sensor, went to start the car, nothin doin. wouldnt go, do, or even try to do, anything. so we towed her up the hill she was parked on, and let her go and i coasted down the hill steering into the garage so we could replace the sensor. so we do that, still nothing. wont start.
so.. i take my dad up (mr. i dont like ecm'd cars or working on them at all) on his idea of looking at teh rocker arms, cause he is convinced that the valves arent opening right. i take off one of the valve covers, lo and behold, the rocker arms (After testing) are ALL loose. every last one was so loose i could run my hand across them and move them with just the touch of my hand (without grabbing and moving). so we readjusted them and now it all works.
my problem is tho (my boggle?) -- how did they come loose in the first place. we had tightened them down before. cant figure out why they would come loose after the lash had been set. (we tightened them, put the valve covers on, put the engine in, attached everything and the problem got progressively worse).
cant figure it out for the life of me. any ideas from the technical people?
thanks in advance...
