Hi Guys

I opened my head cover on the way to check valve clearance, and found my camshaft holder cover has cracklines on it.

It got me worried sick. Is this thing gonna break?

Anyone has seen these before? Please give some thoughts

Thanks

 

Those are just casting marks, not cracks. Don't worry about them.

 

You made my day!! Thanks!!

 

Yeah demon is correct. A lot of cast aluminum parts have lines like that and they can be an optical illusion to the eye at first glance. I see them all the time so nothing to worry about. If that cast aluminum cracks or breaks you'll know it.
