Water pump replaced, still leaking coolant

[Lgibson]

I would climb up on the engine, reach back to the rear heater manifold pipe and feel for coolant slime, even though it is new. Ours has been oozing for 6 years now, about a pint every 3 or 4 months, not enough to drip but I can see the orange stain way back along the ******. Bought a new manifold pipe but am waiting for front crossover or water pump failure to make it worth my while.

I wouldn't wait for a front pipe to fail. If the front pipe fails and you don't shut the engine down immediately, you'll have a pretty easy time replacing the rear crossover while you're doing an engine swap.

Bad pump? I had one fail in less than 3k kms and a month after install....

Seriously? Was it an OE/Genuine pump? What was the failure mode?

OE which are generally just rebuilds. Bad bearing.

Replaced it in August along with the front crossover. The original leak was from the crossover pipe seals

 

[Lgibson]

Yes, I heard that.
My pipe just seems to ooze along its length. It must tbe porous in some way. The seals are fine.

Does it have a seam along its length; I forget? Either way, if it catastrophically fails, big problem; I would replace sooner rather than later
