Cam bearing surface slightly rough?

Maybe Frank Urb has been in there....

Just received 8 (only) of the sealed power HT 2236 lifters in the mail. I emailed the seller that I was short 8 and he refunded half my $102. Oh well.

I thought I read somewhere that these lifters would suffice for the stock cams so being cheap ie 102 for 16 lifters, I jumped on them. Are the mellings that much better?

Sure while you are in there lol, I just saw a set of brand new Stage 3 cams for sale for $3400. They are ground from the original GM blanks lift was 0.454" and duration was 242º. I cant find the link now, but it said there was 1 set left.

So long as there isnt any excessive wear and you are using teh appropriate oil, you should be fine.

Anyone have the p/n for NOS GM lifters?

peace

The Scotchbrite i'm talking about is the green scrub pads you buy in the sponge section at your local grocery store made to wash dishes and used by hand,some sponges have this stuff on one side.
I use this stuff to clean head & cam cover surfaces from old aneroabic sealent w/parts cleaner it does not take off any aluminum to do so you'll work your fingers down to the bone.

Of course anytime you take things apart you wanna clean eveything thoroughly before putting it back togather,i thought this was common practice when assembling a motor,i didn't think i needed to explain this.

Sorry for the confusion.

Just so you have something to compare, here's a pic of my cam bearing surface when I removed covers earlier this year. Took off cam cover to replace breather vent material to relieve crankcase pressure.







As Pete said I used the Scotchbrite to clean surfaces before reassembly. BTW, cams had already been run several thousand miles at this point.

For what it is worth, mine looked about the same as well. I shrugged and haven't had any problems in 10k miles since. Light duty Scotch Bright sounds like the way to go - if only to take the microscopic edges off. Maybe some light oil to go with the SB would be worth considering?

Is that normal wear for 10k miles? What's it going to look like at 40k miles?

I can't honestly tell you that what you see in the pic is wear from having run cams. For all I know this is what it looked liked originally. The motor these covers are from has about 30k miles on it. As you can see from the corresponding cam journal, there does not appear to be any damaging effect.

True, true...

Here's a couple pics after the scotch brite. The only stuff I had on hand was green. Also used wd40 which seemed to help a little. I don't think I want to go any further. You can't feel the scratches that are left. Thanks for the pics of the cam cover journals. Mine are similar.
