I have one noisey lifter that i cant shake. It's definitely a lifter because it bleeds down overnight, starts off shockingly then pumps up to a light tap. Only one. I've reset preload three times to be sure, had three different people on the stethoscope, can't find it. So i'm thinking new lifters. I'm thinking that pulling, cleaning and inspecting the old ones is an average option as new lifters are a fairly economical purchase.
The cam is less than 6months old, but gets driven a few kays each day, to and from work (after a proper break in when i first got it).
There are two conflicting sides when it comes to putting new lifters on "old" cams. NEVER do it, or do it all the time, just give them a light scuff and repeat break in.
Thoughts? |

Lifters are only about 6 and half $$$ each, theyre not expensive.
They will be fine on an old cam.
The other option is to just rev it harder and drown the noise out.

You can replace the lifter. Plenty of moly grease and run it in as if your running in your cam. About 2500 revs for about 10-15 min. Or if the lifter is not externally or internally damaged, just replace the guts of the lifter with the guts of a new lifter. Make sure you bleed the lifter before putting it back in. This way you wont wear out your cam.

Cheers. If i can find which lifter is dodgy then i can strip/inspect or replace parts so that the body remains. But ive been told not to bleed these lifters when installing them new? Just good assembly lube and of course, crank the motor for oil pressure. |

If you use moly lube change the oil and filter after the cams run in. Moly can block an oil filter.
