Strange water Leak (Urgent help toyspade)

[dnalunchie]

Ok guys ive got a 1987 1.3 carbed swift

A couple months back it started getting hot and leaking water alot so we replaced the Head gasket and it all went sweet

Then about 2 months later it started getting hot again and using alot of water

So I took these photos of the water leak and it seems to be leaking from around one corner of what Im guessing is the sump?

Its dry elsewhere in the engine.

Before i got a chance to replace the BHG last time the engine did get pretty hot a few times so maybe the block has gone soft and wont seal properly?

There are no bubbles coming from the radiator cap when the engine is running and no milky residue around the oil filler cap either

Also the leak only happens when the car is running or when its been warmed up and will leak for a few moments with the car off (I think)

What are my options guys?

Strx7 has already hooked me up with a GREAT price for a new engine but i dont want to go down that road if its not nessecary?

Just rang a mechanic friend of my, suggested it could be a leaking water pump as these are down by the cambelt on the drivers side which is exactly where the leak appears to be coming from, any thoughts here guys?

fukd water pump, when the seals let go the water exits through a release hole which usually winds up dripping off the bottom of the block/sump under the timing case

[dnalunchie]

Oh, if this is the case I will be VERY happy as thats a cheap/easy fix

Anyway I can check if thats the issue for certain?

if you can see the water pump pulley, there should be 2 holes on the water pump housing quite near the pulley, chances are that the lower one will have water coming out of it. Based on the symptoms it's almost certainly this, as the increase in pressure from warming the engine up forces the water past the seal.

in this picture you can see the seepage hole on the snout that extends from the pump housing out to the pulley (this is just a generic water pump pic, but gives you an idea what to look for)

Why haven't you got Laas onto this? Or has he refused to help you with your cars anymore?

[dnalunchie]

is there any risk in me trying to take it apart myself?
what do I need to do?

NO, no such thing, but it does give the head bolts a bit of a stretch and some designs/sizes will be little loose & need to be re-torqued ASAP.

Is this just sumthing I can go at with a box of tools?

I believe I have to take the belt off but Is there anything I have to be wary of? Should I disconnect the batter for instance?

[Malcolm]

yeah it's usually pretty simple. Disconnecting the battery is usually a sensible precaution.

How much mechanical work have you done before? Provided you have a small amount of mechanical capability it should be doable in a couple of hours unless there's lots of crap in the way. Count the number of bolt holes on the new pump and make sure you've removed that many from the old one before you try to pop it off (there's usually a bit of force required because the gasket can stick them together pretty well). There is sometimes a countersunk bolt holding them together, which can be hard to spot, and it is usually a Philips head too which can be a real pain.

If I remember right you will need to mess round with the cam belt tensioner to replace the water pump on these motors. If you have the tools and know how to change a cam belt then this will seem pretty straight foward.

correct, cam belt tension attaches to water pump

i'd reccomend doing the water pump, and putting a sealwell cube into the cooling system, it should be good for another 20,000km +

i'd reccomend talking nicely to me, and putting a G13B into the cooling system, it should be good for another 120km/h + grin factor

edited for truth, and logic

No, if you have to ask, you can't, and considering the other questions asked, I'm pretty sure you can't.
Can you afford to learn the hard way, if not then don't?

Woah! Negative bear says teach a man to fish!

Murphy's law says that the last headgasket job done on the car wasn't done properly.
Needs doing again.
Too much pressure blows the coolant our through the seal.

Murphy's law? Sounds more like MAGN1T's law to me.
