I bought this L33 aluminum block from ebay & while cleaning it up today & fitting the ac bracket & found one of the ac bracket mounting bosses has 3 small crack's in it. I tightened a bolt into it & it was holding no problem.

It doesnt looked banged on & was wondering what you guys think about it ??

Its just gonna be a daily driver nothing crazy...should I be concerened ???

I highlighted the cracks in red so you can see them.

Me personally, I would either weld em up myself, or have them welded up. Just my .02

Must be stress cracks. I'm no expert, but I feel the cracks will progress further if nothing is done about it. I would look into blending or possibly weld if that type of aluminum is the welding type.

Most likely was in a front-end wreck and the compressor got stuffed. I'd be looking everything over real close...

^What he said. But if everything checks out, I'd just have someone stop-drill the cracks, weld it up, and re-tap/chase the threads.

yup but if there not bad stop drill them at the very least and leave them. dam i cant rememeber what we stop drill on AC alum i think its a drill bit thats .125


or you can some one weld them up and retap

mostly likey you could leave it the way it is and be fine but i wouldnt risk it
