Valve Covers Cracking???
Don't know if this belongs here or the general section, but.....
Was doing some cleaning today and noticed my valve covers have what appear to be cracks around the coil retainer holes. Does anyone know if this is a problem with the LS1 or just mine? Seems to be more dirt/oil residue around that area as well. Does anyone else have this problem?
Do these look like cracks to you??
Before cleaning...
After cleaning. Can you see what I'm talking about?
Do I need new valve covers?

I think it looks more like a casting flaw than a casting mark. I agree with the wait and watch as well. Doesn't appear to be a real problem as that build up probably took years to form.I wouldn't worry about it unless it's one of those things that just bug you 'cause you know it's there!!

Thanks guys. It does bother me a little to know that they are there, but on the other note, it is under the covers and coils. So just to make sure, I am going to look at them a little closer this next weekend just to make sure for my own piece of mind. A little magnification and some dye pen should do the trick. Appreciate the comments everyone.

Welcome to the wonderful world of the low bidder parts. There's no need to use a better alloy or a thicker casting when cheap plastic covers dress the engine bay. GM used plastic valve covers on the lt engines from 93 on. The ls engines also have plastic intakes, tell me fast don't make a tidy profit on thiers. How many pennies does GM make using nylon gears instead of steel on the headlight motors?
