LS cam bearing failures
Lately in the shop I have seen some 6.0l GM engines come in with spun cam bearings that have caused a few otherwise good cores to be useless. Is anybody making an oversized OD cam bearing set for these blocks? If not does anyone know of any other fixes?

Re: LS cam bearing failures
Durabond has some oversize OD cam bearings available. Not sure about LS applications though. Give them a call.machinedave wrote:Lately in the shop I have seen some 6.0l GM engines come in with spun cam bearings that have caused a few otherwise good cores to be useless.

Re: LS cam bearing failures
last I had a problem, Durabond did have .020 undersized ID bearings for the LS. Bored them to size
Now for the OD problem, not sure what you will get into

Re: LS cam bearing failures
I can get another 6.0L for about $400 so I have to consider the cost of the oversize OD bearings and the machining to oversize the housing bores but it is so hard for me to give up on a "patient".

Re: LS cam bearing failures
I just discovered a set of oversize OD LS cam bearings. Durabond part number CHP-25R1.
Re: LS cam bearing failures
More Durabond info for LS, cam saver and block saver info as well as some replacement parts.

Which cam b location spun? We just fixed an LSX block by boring spun housing bore for bearing for a different location that was .020 bigger od.

Re: LS cam bearing failures
Its usually the #3 housing bore. I've thought about that too. Did you have good alignment after boring just the center?
Re: LS cam bearing failures
Yes, good alignment. Cam bearing squirmed out towards back, leaving a small, un-damaged area to measure and center up on. We used .0055 press fit.
