I am about to OHM my glow-plugs since I am sure a few are bad, I have the specs to look for, but do I have to test the at the valve-cover connector? (tight and hard to get in there) or can I test them where they connect someplace else? (I am aware to make sure I test them coming FROM the valve-cover)

Also, my Alldata says I have to remove the dipstick tube to get the valve-cover off, is this really necessary? The nut is pretty rusty at the oil-pan, so I would prefer not to have to remove it. Thanks!

 

it is not necessary to take the oil dipstick tube off of the pan. However, it bolts in up top on a valve cover bolt with an extra nut on top .. that is the part you must remove


and as far as i know, the only way to ohm glow plugs is to test the pins on the valve cover. yes, they are hard to get to, but definetly not impossible.

 

ok, thanks for your help....
