2001 3.0 Lifter noise just started @ 155K

[palmsprings]

I have about 155k on my 2001 M/S 3.0. Owned since new.
Never had lifter/tappet noise
At startup,tappets/lifters make noticable noise.
They seem to vary in intensity. sometimes quiet sometimes loud enough to hear at start up while in cab.
Oil is and has been the acceptable range marks on the dip stick.

Any ideas?

Pretty common at this age, you may need to bleed the lifters out by slowly revving to 3k then snapping the throttle closed then repeat 30 times or so. try that some have used seafoam with good results.

where do you get that "'practice"?

the hydraulic lifters get fill with gunk and they not working properly.....so best way ,,,,clean engine deep.....or just replace lifters..

I used seafoam on my 3.0 and it stopped with in 5 mins. and picked up a couple of mpgs running it through the gas tank.

i SWITCHED TO A 5-30 hIGHmILEAGE OIll and that Seems to have quietened it down.
Its accumularted 25K since I posted this original question and switched oils. its still quiet.

Still,I think Ill do as suggested and add the seafoam .

Try the rev sequence too, that seems to clear them out significantly, at least for me anyways, but now the tapping sounds are back when starting up again. Strangely enough right after I replaced the valve cover gaskets and all the top end stuff on the engine, I didn't have ANY valve tapping sounds for over a month, it was nice but sure as sh@# the tapping returned after a month...curious though..

I will try the throttle idea tommorrow and also want to try sea foam but am scared of causeing more good than harm i dont want be the first to make a complaint about seafoam i always herd good things about it but never used it.
