Roller Rockers noisy

93 LX · Apr 1, 2008

Does everyone have this problem? I am either not setting them correctly or they are just junk. The engine sounds like a sewing machine when I rev it up and to be honest its embarassing since from behind it sounds awesome. Can anyone help me figure this out?

What brand rockers?

From what I have seen/heard, most roller rockers make noise. A friend of mine has a nice set of rockers....I forget what brand, but even after replacing the lifters and adjusting the hell out of them, they still sound like that.

I know mine sound exactly how you describe, I fixed it by turning up the radio.

The last car I owned had scorpian rockers and you barely could hear them at all.

my tfs rockers sound like a sewing machine too you cant really hear it when i rev it though.

My TFS rockers are just slightly noisier than the stockers were. It does sound like an adjustment issue, but it could definitely be brand dependent.

My TFS rockers are a lot quieter than the stockers. Did you make sure the rocker was properly seating on the valve stem?

I have FRPP and they are loud

I have the crane Cobra rockers and mine are almost quite as the stockers.
This is after the 3rd adjustment tho. I adjusted both rockers on at the same time on each cylinder following the firing order.
I believe a lot of ppl are experiencing noisy rockers because the adjustments are a tad bit off.

i have the same rocker arms on my car. i've adjusted them twice and they still make a tad bit more noise than my stockers did. they've gradually gotten quieter over the past month, you can only hear them a bit at idle. still kind of annoying though.

is there any chance they are hitting your valve covers slighty? have you checked them for any scarring?

93 LX · Apr 3, 2008

No they do not hit, although they did when I 1st installed the rocker covers. I had to remove the baffle in the cover to make them work. I will try to adjust them again. Can some one tell me the best way to do it? I may be doing it wrong.

It really easy I am thing you use IOEC when the intake starts to open you tighten the nut by finger until the pushrod is hard to turn. then go a half turn and lock it down...then when the exhaust starts to close then adjust intake same way.....someone correct me if I am wrong I could have them backwards

BlownFiveLiter · Apr 3, 2008

I did mine by feeling for the slightest bit of resistance when turning them. Once you feel it, 1/2 to 3/4 turn and lock it down.

I did mine the same way as StangGT1995.

89lxcoupe · Apr 3, 2008

you can't adjust them doing the spin method if you have any that are not pumped up or are bled down they will be to tight i have had it happen before, the best way is to have the intake off but that is very slim so i make sure both valves are up and closed on the compression stroke and go a 1/2 to 3/4 and have never had any problems or never hear the rockers but i try to look at the rocker and feel when i turn the nut to make sure it isn't preloading them then lock them down , but everybody has there own way of doing it ! my stock bolt down rockers on stock 37 heads are loud but i think my rocker tips are wore !

Could be rocker geometry, comp cams has a nice pic of what it should look like.

Also check for clearance between rocker and retainer, between the edge of the retainer and rocker and on top where the rocker pushes on the valve stem as the pedestal rockers have an overhang on each side of the roller, im sure its ok but its worth a look.

This is the method I use and have had great success.

I have the same noisy roller issues. It seems like a common problem

I thought it was because I was using cheaper rollers. They are Crane Blue Racers. I checked the valve cover clearance and adjusted them several times...but still, when after the engine is heated up, they're noisy. Worse at idle.

Does anyone run a set of rollers that aren't loud????

I am not sure anout this geometery thing but I will say the engine was built by a respectible company. I will try to adjust them this weekend and letcha know what happens.
