water leaking down the block at the front and the back

[albitz]

oil cooler cover plate/coolant bridge ? :-/

[tunnie]

front only would suggest water pump, rear only could be core plug, but for both does point to oil cooler plate.

Worth a quick strip off the plenum and fuel injector manifold to see whats what 

[UrbanFox]

would this cause over heating problems as well?

the water appeared to be passenger side on both leaks

thanks!

[albitz]

yes, any coolant leak will cause overheating.

[UrbanFox]

looks like I'm stripping the top end down then.

will it be easy to spot of it's leaking?

[albitz]

I would think you should see staining where the coolant has keaked from.

[UrbanFox]

cheers! I'll start stripping it next weekend!

[tunnie]

yes it will be all wet! Take injection manifold off.... (another thought as i type it could be stat leaking)

towards front of the engine there is a big pipe, exiting to the passenger side, thats the stat to transfer pipe, check this for leaks.

The oil cooler plate is long and has lots of bolts down each side, easy to see if coolant has been escaping here.

You need to put some pressure in the water system when you have the plenum, inlet manifold removed before removing the heads etc.... you should then see where the leak is..

Hope that helps

why do I need to remove the heads?

the stat and waterpump have been replaced recently and it wasn't leaking after those had been done

I am assuming your refering to me?

I have just read this thread and it came across to me that you were thinking of removing the heads.... I must be wrong then.. but what I am saying before going to that length get the water system pressurized whilst a few parts are removed then should make it easier for you to find this leak...

Just trying to help.

yes I wads Daz, didn't mean to come over arsey lol.

how would be best to pressurise the cooling system? I don't have an air compressor unfortunately .

what parts should I remove before testing? plenum, inlet manifold? thanks

You water system pressurizes to about 10-12 lbs when the car is running, so a compressor would put to much in mate. I use a hand pump that has a gauge on it. I have a spare coolant bottle cap which (I thought I had invented until The Master told me he had one  ) you need to drill a hole in big enough to get a pushbike valve through. I then took the cap to pieces then used an old innertube pushing the valve through the drilled hole, then put the cap together again. Screw on the "New Cap" then pump using a hand pump to put a few pounds in... not to much we dont want burst seals etc...... you will need to put some grips onto the couple of water pipes that go to the plenum aswell else the water will just pump out of there.

Doing this after you have removed the Plenum, Inlet Manifold  wil allow you to see the leak more easily, hopefully

[UrbanFox]

thanks Daz!

what are the chances that I will have to remove the heads?
