Noisy lifter replacement

I have been thinking about replacing the lifters in my 2.5L It has 132k miles on it and one of the lifters is making some noise. Most probably won't notice it but it bugs the crud out of me. I looked in the Haynes manual and it says you can pull the lifters out with a tool or sometime with a magnet on a rod. It also says that if your lifters are worn you should replace all of them and that you should not put new lifters in without replacing the crankshaft.

Has anyone done this and have you done it without replacing the crank. To me if you replace the crank why not just rebuild or replace the engine. What happend if you don't replace the crank? I am sure someone has tried it???

You might want to check oil pressure with a mechanical gauge. All the 2.5's I have seen with noisey lifters had oil pressure issues due to sludge.

Definatly change all but I would say they meant the cam not the crank. I would check the cam lobes for wear or scoring. 132,000 miles isn't a lot but I would check the rod bearings and if there is wear I would go ahead and rebuild it and call it good. Just me.

So are you saying that if the lobes aren't scored and the bearings are good to just replace the lifters only? How big of a job is it to replace the lifters? Valve cover off, rocker arms removed, and push rods removed I am assuming? The extract the lifters and check/replace. All valves will have to be re-adjusted since rocker arms removed? Has anyone tried this?

If you are on a budget and want to get on the road yes. Also if it running strong then yes. All depends on you.
