I guess that you are talking about a hydraulic lifter for an auto engine. There is no repair for these. They can be converted to "solid" lifters or used as paper weights.
If a lifter is stuck in the lifter bore and won't move, it has probably ruined the cam. The procedure would be to install a new cam and lifters.
You can't fix a bad lifter, replace the bad lifter with a new one.
how much would it cost on a 2004 mercury sable
The year, make and model would help.
It would cost $725 bucks
It depends on what is broken on your water heater, as to how much it would cost to fix it. It might actually need to be replaced and be more cost effective to replace it.
I would assume it will cost anywhere from $100- $300 to fix your car brakes. Because they are an important part of your car it can be expensive to fix them .
about $4,739
250.00
$6,215,349,665
If a lifter is worn out you are not going to fix it, you will want to replace it with a new one.
3,800!
