Re: 2002 3.7 Lash Adjusters
Probably best to get rid of most of the dirt with some pressure washing or using running water and a brush. Not familiar with the 3.7, but on the 4.7, i could just drop the harness far enough so it was laying on the lower side of the cylinder head. Eventual dirt which drops on the camshaft or the surrounding area can be removed with some lint free cloth.
Also put some big pieces of lint free cloth in the openings for the oil to run down and where the timing chain runs, to prevent any foreign material to fall down.
He, i didnīt see the tool when i looked at your tread before. Looks very nice. You will use it to compress the valve springs, so that you can get the rockers out? Are the hydraulic lash adjusters noisy?
