Fixed noisy lifter during head change
Nothing radical here. Just a rebuilt motor (4.2L) that ticked on one valve since day one. Drove it like that for nearly 3 years. Changed pushrod, rocker arms, tried shims, etc. Nothing worked. Finally decided to freshen up the head and when I had the old one off I put in a single new lifter. Voila! Nearly silent engine. Definately no tick. Now it's time to see Midas about that lifetime warrranty on my muffer. It rattles just off idle.
By the way, my motor will actually idle smoothly at 400 RPM with the Motorcraft carb. Musta had some slight intake leak cause after I changed the gaskets it idles even slower.
Can't wait to get the 4.56 gears in. Axle has been in the shop for over 2 weeks. Time to give them a call. Summers here, and that my time to crank the wrenches in the driveway and fix all that ails my favourite vehicle.
