BHG / Waterfall

WrenchMonkey · 09-19-2006, 05:27 PM

First of all I would like to say hello to everyone on the forum and thank you for all the great information.

I have just recently bought an automatic 1988 Mk.III turbo, when I went to check the car out it had no signs of a BHG ( No milky oil, no oil mixed in the coolant, etc ) and when started it sounded like it ran great.

So I drove it home (aprox. 200 km / 120 miles), then in the morning I went out to move it. Right away I knew something was off.. the dreaded waterfall sound, but the odd part is no sign to indicate a BGH besides the waterfall.

So I am thinking its the first stages of a BGH, if anyone has any other ideas besides a BGH I am all ears. But it looks like I'll have to do a MHG upgrade
a few months early.

doesnt necessarily mean its a bhg, it could just be air trapped in your cooling system. you can "burp" it out by jacking up the front or parking on an incline and topping it off with coolant.

Burp the system- its not hard. then go from there.

if the waterfall comes back you probably have a leak somewhere.
b sure its not a HG and look for other signs of a BHG.
