Cracks in CPU block

They appeared when I unscrewed the compression fitting to put an angle fitting on. I am guessing it is my fault as they must have been on too tight before(?) Anyway, is it a problem? They are not leaking at the moment so i'm starting to just think to my self "out of sight, out of mind". :eek:

I'd get the top changed asap, the crack is only going to get worse over time.

excellent excuse to get a blue plexi top

I had a plexi top crack a couple of years ago, over time it did start to let water through (it killed a 3870

) i would change it asap

I took it apart after doing it & had a close look. The plexi looks quite thick and the cracks are only along the top. It happened about 6 months ago, I only remembered because I just drained my loop to dust my radiators etc. Thought I best post here and ask, I hate the thought of spending more money & not seeing any immediate benefit

CRacks don't have to go all the way through for it to leak, they just have to give the fluid a bypass past the o ring, which looks possible from that pic.

You have a valid point that I hadn't thought of :mad:

I'll be keeping my eyes open on the MM I think.

I would get that top replaced straight away! You've a nice rig there, it's not worth the risk running like that.
