In the interest of both time and money would be worth it to try to clean them without removal to see if that would get them flowing oil freely and moving again and possibly avoid/postpone replacement for a bit?
It seems removing the rockers and spraying B12 Chemtool down the push rods has quieted them for quite a few people. Of course changing the oil thereafter to remove the Chemtool.
Having to pull the LIM means the task is going to take more time and gaskets than I thought to do correctly, I was hoping that wouldn't have to be removed.
I ask because if go after replacing them I wont be able to get the tires (about to fly off the car, literally afraid to go over 35mph with them atm) this things needs for a while after the cost of the lifter replacement done right and I won't have the car available for some time as there are other tasks ahead of this car on my must do list at the moment. Its not my DD, but my other alternative to my work car, that I can't drive for errands and such on the weekends, is a 25 yr old truck with a straight six that drinks gas at a high rate.
Thanks for the advise so far, I appreciate it.
