Okay so here are a few photos, I'll see if I can do this right.
Lots of folks have been asking about this type of repair lately so I thought I would snap some photos for clarification.
Without great detail right now, here are some pics of resealing the coolant crossover or "water pump housing".
I'll answer questions when I have time.
The first picture shows the engine with the crossover removed, you can see it's no party to take off.
the second shows the housing, on the right side you can see where the water pump is housed. I'll take a quick pic of the pump from the other side in a few mins.
The third is to show you what happens to cause the leak.
The inner framework of the gasket fails and there is nothing to keep pressure on the seal part (blue).
The gasket collapses inwards and coolant can get past.
I'll add a pic of a new seal so you can see what a good one looks like.
I gotta get back to work. This one has to be ready tomorrow.
Okay, reeeeeaaal quick.
Here's the pump with the cover removed so you can see how it fits in there.
Also this is an updated crossover seal. It's white with a black seal lip rather than black with the blue.
