Title: My thirsty diesel
Post by: veritas137 on September 19, 2004, 07:06:06 pm
Car in question is an 86 Golf.  And no, it's not thirsty for diesel, it's water that it likes to drink.

I had some cooling issues that have since been resolved, but oddly enough it still consumes about a liter of water for every hundred miles of driving.  All the external leaks were fixed, no internal links that I can find.  Only thing that looks out of place is a slight leak on the front of the block.  So I'm guessing the head gasket is bad.  I'm not quit ready to do a headgasket change, and it looks like the previous owner may have tried some epoxy to seal it.  I'm a big epoxy fan and was thinking of cleaning everything up and putting some more on.

Anything wrong with this as a short term solution?  Also the car doesn't drip water while sitting and I couldn't see any water spraying out or anything.  Could there be another possible problem?

I just saw this happen on one I drove -

When hot a crack opened up on the back side of the engine - because the engine was hot - it just smoked off - and becasue it was a pin hole - not much  - but it drained off enough to warp the head  when the owner[not me] was not paying attention.

By the time - it china syndromed - it drank stuff quickly - but I have to tell you that when I drove it - 60 miles or so - it acted good - normal heat - normal all else.

I can only figure that it was the owner who missed the signs -

So look hard - look often!

how does the oil look? milky at all? any swirls in the coolant reservoir?

a litre per 100km sounds like a lot... might be worth putting some dye in the coolant and shining a black light around the engine bay and under the front of the car in the dark if its really got you stumped. sounds like a HG to me! good luck  :)

It's not water getting in the oil or vice versa.  I've seen that before and it was the first thing I checked.  Also no smoke or anything so it's not water getting into the cylinders.  Pretty sure it's just water coming out the front of the headgasket while the car is running.
