Why does it start happening in the first place?? I've got the valve cover off the rockers are only a year or so old

 

If you had the heads off, and used a felpro head gasket to reassemble, the new gasket is thicker. It moves the heads farther away and takes away your preload. What brand of rockers did you buy and did you replace both the rocker and the stand?

 

So I would need two rockers and one bridge?? Help me out with a parts list

 

Yes 2 rockers, 1 bridge/cylinder. They actually come as a kit.

Wait a minute. You pulled your heads off for rocker noise?!?

Pulled the heads off to check the gasket to see if it was blow and put a new one in also I almost dropped a valve so I needed to make sure everything was kosher internally, cleaned everything and put new retainers on the valve spring and put it back together. It was good to get in there and check out the bore job and to see the condition of the heads and to make sure there was no water and such.

 

Ok guys Ive put the new parts on and on the number 5cylinder driver side second rocker I have to keep lossening and tighten the bolt to keep the sound away but as soon as I take my socket off it it starts chattering again it makes no since I can sit there with it running loosen the bolt retighten and it'll go away and then in 5 seconds the sounds bback it's driving me nuts it's new rocker new bridge new bolt new lifter everything is primed up plenty of oil I don't get it

 

When you changed the lifters, what did the old ones look like? Was that one concave on the bottom? It's quite possible you have a damaged cam lobe. The other thing you can try is take a quiet set from another cylinder and swap them to see if the noise moves.

 

The lifters were not worn at all I changed them for the sake of changing all of them while I had the intake off, I'm dumbfounded

 

It may just be that the new head gasket caused this. Swap a quiet set for the new set and see.


Did you by chance send the heads out to a machine shop while they were off?

 

Negative on the machine shop I'm swapping some right now to see if the sound moves post back in 5min

 

Sound didn't move still same cylinder same problem can loosen and retighten and it will go away for a few seconds then comes right back

 

As a down and dirty fix, you can file 1/16th inch off the bottoms of the stand that you removed originally to experiment with. You have to make sure you take the same amount off each side and it's square. If it still persists you quite possibly have a bad lifter or worse, a cam lobe that's worn.

 

I'll just stick out the noise till I can get a new cam I dont think I'm skilled enough to file those down correctly

 

It's not hard to file it down, they are very soft. That's why I suggested to play with the one you took off. Sand paper and a flat surface work well also.

 

Ok I file the part that touch's the head

 

Yup.

 

Ok I file the part that touch's the head? How do I measure how much to file? I'm sorry I ask so many dumb questions lol this is my only car and I want to do things right the first time.

 

Measure 1/16th of an inch up and make a mark on both sides, sand or file to the mark. Try and make them as square as possible.

 

Hey when you get a chance get a good look at the cam down the lifter hole.. Turn cam all the way around look closely for something missing or excessive wear.. I had a GM engine where the factory cam started to break in small chunks at the lobes.. I could never get the rocker to stop clattering..tighten a little go away then come right back..

 

Good idea next time I have the manifold off I'll do that this is my ownly ride so I'll get a look soon

 

If the cam was worn or broken wouldn't the lift be affected because I've got good lift

 

How'd you make out?

 

Havent tried the filed ones yet trying to get them perfect

 

Not necessarily will it effect the lift.. However if the cam was not broken in properly or old cam or cheaply manufactured cam or ran low on oil it can fall apart, start to destruct in pieces causing the exact noise issue you explained...my engine ran fine in my truck but the clatter wouldn't disappear with adjustment..I may still have the cam if I find it I'll photo it and post it here..

 

okay in the process of filing down gonna let you know the results

 

no differenece still chattering i dont get it man

 

When you changed the lifter did you soak it in oil first? Did you check the pushrods are all perfectly straight? Roll them on a piece of glass or something?

 

Take another 1/16th off, keep taking a little more until it quiets. I wish you had access to one of these to compare the lift of some of your lobes.

 

found the culprit bent pushrod cam is fine everything else is fine the chattering one has a bent pushrod with a knick in it just didnt look at them hard enough i guess

 

haha i hope thats the culprit but the pushrod is def bent, gonna order two from the parts store, i cant believe that its been a pushrod this whole time

 

Hmmmmm, ok.

 

Excellent find.. That's something you will never forget.

 

I assumed we check that already, any how it should correct your issue.

 

haha i did check i jsut didnt check good enough, im learning but your right i will never forget that sound and now i can take those rockers and vlavle covers off in my sleep lol. thanks for all the help guys

 

well new pushrod did nothing sound still there same problem can loosen bolt and then tighten down and sound will go away for 2 seconds then comes back

 

im literally at my wits end its taking so much away from the car and its pleasure

 

Collapsing lifter?

When this is all over, you'll have to paint he name "Christine" on the trunk lid.

- Eric

 

If taking a little bit more of the stand does not work, it's time to pull the intake again and check your lifter and cam.

 

well i put the lifters in like 2 weeks ago, i guess im gonna have to pull the intake again im gonna try to take some more off the stands today and then when i can afford intake gasket and a cam ill pull the intake off. man this is a bummer WHos Christine lol
