I have always heard good about the M22 cams and I am about to sell my Skunk2 Stage 2 cams for them but I recently heard that the M22's eat rocker arms. Just wondering if any has experienced this before.

 

I've seen one instance where they did, and that was with used rocker arms. They are no more prone to eating rocker arms as the Skunks or comparable.

 

Maybe if your valve springs are to stiff it could happen,or a loss of oil presure.
But that could happen to many cams.

Maybe I am not reading your comment correctly but why would you specifically state they were used rockers? I bet 99% of the people on here that have swapped cams at one time or another have reused their rockers.

No offence, just wondering if there was a hiden meaning I was missing?

Thanks

 

i think what he means is that:
you should inspect your rockers PRIOR to any camshaft installation.

if they are 10-14 year old rocker arms, or have had different camshafts swapped in, chances are they have scene a lot of mileage and they are a wear item.

Most of HT i would say does not switch there rockers out when changing camshafts, and i would say the majority do not know how to identify rocker arm wear correctly.

In SOME CASES, when a product gets blamed for destroying something, its not neccesarily the manufacturers fault.

so, check your rockers before installing camshafts

Im pretty sure that there was a problem with the installer using incorrect valvelash and hat caused the damage. Rm products are very good, and robert will do whatever he can to help you out

 

thanks guys for the input

recheck what. i have heard this seperate from the obx thread. recheck thanks.

 

Ive had some experiance with eaten rockers.I used some high lift h22 turbo cams and destroyed my rocker arms.Turns out it was incorect valve guide clearance.It caused the valve to bottom out.It put extreme pressure on the cam and rocker ,the rocker being the softer of the two metals.Anyway to adjust them put the head in the oven and heat to 300 degrees and adjust .and yes my wife went nutts.hope this helps.

 

so what i'm getting out of all of these are its usually not so much the cams (unluess OBX) but incorrect installation. these comments have helped out alot. thanks.

You got it. Just like the vast majority of computer problems occur between the chair and the keyboard.

 

ordered a set today, anyone looking to buy some skunk2 stage 2 cams?

 

The new cores used for M22's M24's etc have excellent rocker arm compatibility.

But there are instances in which rockers arms are 16 years old or have been run down a lil on other aftermarket cams and those don't do so well.

On clean installations with new rocker arms wear is basically non-existent from the times I've had a chance to inspect them.

 

What I noticed on the rocker arms in my ITR head that had 125k km's on it was that the pad on the rocker arm the primary lobe was riding on showed signs of wear. The reason being that the primary lobe on stock ITR cams are a lot narrower than the pad on the rocker, and as a result the contact patch was worn down to the extent that it could easily be felt with a fingernail. So if you are then going to install a set of cams where the cam lobes are wider, then the cam would only be in contact with the rocker arm pad in two small spots, and this can't be too good

Luckily for me I had a B16 head with just over 40k on it with rocker arms in much better condition, so I just swapped over the arms and shafts from that head. A lot cheaper than buying new rockers, which are big bucks.
