New water pump leaky :( copper spray ok?

[scheides]

First off, special thanks to Kracka and TKRPerformance for helping me do the tbelt job on my car last weekend. It took a long time, but it was a great learning experience! Everything runs like absolute clockwork, but I have one small but ultimately awful issue: the water pump leaks out the back of the block. It does not leak in teh timing area (all belts are dry) and does not leak at the return pipe (normally across the front of the motor on a dsm, it's on teh back on an evo). Its like its leaking out the side of the gasket!

Anyways, I used copper spray on both sides of the gasket, but not the bolts (thought that'd be silly), so I'm not sure if i scraped the gasket going in (it is a damn tight fit!) or if its leaking past the bolts or if copper on the gasket was the wrong thing to use?

Any advice would be appreciated, I am not looking forward to ripping the car all apart again, but you live and you learn.

PS - yes I re-torqued those bolts holding it on near where its leaking.

Should of used regular rtv copper selant, not spray, it works alot better for applications like that. And Im assuming its a new gasket you used, but how long did you let the spray copper sit before putting the gasket on? It might have dried up too much then just gave way under preassure.

Copper spray on a gasket is better then the RTV shit. People tend to put to much on and it clogs shit up in the motor.

Check the back of the copper spray can and see what it says for wet applications, how long its suppose to set up first before using. When I use it, I always let the car sit for 12-24hrs after using it. Same with RTV.

Did you make sure to get all of the old gasket off? Like 100% positive there was no old gasket left on the block?

I used copper spray on mine when I installed a new one awhile back, and it worked fine for me. That's about all I have offer though, sorry Scheides...

That sucks Scheides. Ive always used that sealant that never really dries, its a reddish gooey can of stuff with a brush.

Copper spray should not cause any problems. Did you get all of the old gasket scraped off good?

You just gotta be a pro. :bengals: I swear by the stuff. But just like all gasket stuff you do have to let it fully cure before exposing it to fluids, like others said.

Usually you only need to use a light coat of copper spray if you use any at all. Honestly though, if you used a new gasket, there shouldn't be any reason to use copper spray anyways... Just make sure both gasket surfaces are squeeky clean, and you'll be good to go.

Gotta make sure you didn't pinch the gasket as well, regardless of how awesome your torque wrench is. Sometimes you're just better off with a snug and extra partial turn than reading what a wrench is telling you.
