Ok recently iv been having a ticking noise.it sounded like a header leak so i put new gasket on and no change in the tick so i pulled off the valve cover and ran the engine with it off and the sound was definitely coming from somewhere in the valve train.turned off the engine and inspected to see if any rockets were lose or had any slop in the valve lash .everything seemed to be right.the engine has about 800/1000 miles on it and have not changed the oil yet.i think a lifter my be collapsed ... was thinking on re doing the valve lash a see if it go's a way...here's some specs on my engine
I used to pretty quiet .but i have been racing it a lil ...it still builds great power but its only that one at as been ticking the other side of the engine sounds fine ..but you mite be right.i mite have a spec of crud in the lifter.i did notice when i have the valve cover off running the engine that one of the rockers didn't fill up oil as much as the others were ..so i thinking i should pull out that lifter and clean it or just change the oil with something thicker

I really hope the is not f**led up .i just got it running good .and yes the cam i have is vary respectible in power.well ill try changing the oil .i am probably going to put sine brad Penn oil because of the high zinc it has in the oil

So F bird 88 your xe284 made the same ticking noise then after changing the oil it went away.now if one of the lifter was not pumping oil up to the rockers Like the others were that could make it tick??

Ok changed the oil with rotella 15w-40 and still a tick .im praying it will go away lol

Dose it take i lil bit of running for it to smooth out before it will quiet down
09-03-2012 05:29 PM
Ok i took off the valve cover and rev it about 1500/2000 and all push rods are spinning

Yea i got a 3500+ stall made a big difference 35 mph burnout :)....so do i need to take out the lifter and clean it out or will it go away

It all the time sounds like maybe 1 or 2 mite be ticking .it dose it at higher rpm's to..it sounds a lot quiter but not that much after the oil change

Like I said you may need to monkey with the rocker nut adjustment.
Mine likes generous preload.
Right at the top, typical hot rodder hyd lifter preload is noisey on mine.
You do have screw in or pinned rocker studs , right?
So a full turn of preload ..that sounds like a lot ..i have a rocker studs

Yea i will most likely get a solid cam ..i just don't want the cam to get messed up a destroy my bottom end.so as long as the push rods are spinning it should be ok as far as the cam and lifters go

Ok i re-adjusted the valve lash and still a tick .but when i was adjusting them i noticed one of the rockers slowly raising back up when i stoped bumping the motor over .same side it is ticking from .could that be the bad lifter

Well i took the intake off to inspect the lifters and found one of the cam lobe was roast .the lifter had some pitting and the cam lobe had flat spots ....soooo now im thinking what do the main/rod bearings look like.what is the chance that the bearings are ok
