Mate, I'm interested in your comment on the TD42 water pumps having real cavitation issues.
I recently purchased a Jap import TD42T engine that I'm guessing has around 100k on it. I was advised to remove the water pump to check the state of the timing cover as it's an indication of a badly worn engine.
Here's a pic of what it looked like. If I polished the alloy it would look like new..
There is really no sign of any cavitation problem there..
I bought an original Nissan water pump for it.
