this is the pic I'm referring to, Jake...I can't see a red circled area here. I saw your circles quite clearly in the other photos, and the damage could be clearly seen, regardless. I'm just wondering if there's some glaring obvious thing that I'm not seeing....

waterpump planned replacement
Jake
what would you consider the planned replacement interval for the waterpump? and is there another option with say a metal impeller section?
on the watercooled vw's the plastic impeller would come loose and spin on the shaft resulting in low flow (none) and temp alarm.

That crack was so small that it could only be noted with a hot water pressure test.. Thats why we marked the area with yellow anti-sabotage marker. I used that pic in my M96 engine rebuild school to illustrate the area where heads generally crack. Its the "big picture"
If the water pump on your M96 hasn't been replaced, replace it. Replace it every 3 years after that.
Here is a crack that no one can miss.. Its wider than the Grand Canyon.
One day when I have time to put all these on my site, the world will have a heart attack!

Thanks for clearing that up, Jake. I see the marker you're talking about. As for the picture following that (the Grand Canyon's competition), that's just painful to look at...what a way to K.O. an engine.

Nuts, I guess I should have replaced the water pump when I installed LN low temp t-stat last year (and new OEM coolant)...would have been the most logical time. My car is approaching nine years old with 19k miles on the clock. The plastic impeller is probably quite brittle at this point. Do you recommend replacing with OEM or another?

Replace with OEM only -- I've had two aftermarket ones die -- one at 1k miles
and one at 22k miles.
