Making lifter noise go away
I've had mild "lifter chatter" since I bought my Jeep. After I had the timing chain (had 1.5" of slop in it) and rear main seal replaced last week, the lifters sounded like they were going to come out of the side of the engine along with other internal parts.
The shop refilled the Jeep with 10w-30 and I think that was too thin of an oil for a tired "ticking" old 258.
I got fed up with the noise and rough idle from the lifters not pumping up, so I decided to change the oil to 20w-50. I also added some Lucas Oil engine treatment(the stuff reminds me of 90 weight gear oil). What a difference!!!

The engine has never felt stronger. Actually was passing people in 5th gear up hill on interstate 95 too. [img]images/graemlins/smile.gif[/img]
I figured I would share that with anyone else having a noisy lifter problem.
On my trip to NJ last weekend, the fuel mileage has jumped from 10 to 11 mpg to about 17 mpg. I've never had that good of fuel mileage. I have over 170 miles on one tank and still have about 5/8 of a tank left. That has been unheard of in my Jeep. I think it's from the new timing chain, completely new exhaust, and the fact that I was able to set the timing right for the first time in 4 yrs.
