On a 1999 300m -Finally successfully diagnosed combustion gas leaking
past my head gasket into coolant causing overheating. Used the Napa
Block Test kit for $50. Many posts say go to your neighborhood garage
and get them to use an exaust analyzer - dont know what that would
cost.

My Napa Store did not know anything about this test kit and could not
find it on their computer so here is a site and part number you can
show them
http://www.arrowheadradiator.com/head_gasket_or_combustion_leak_test.htm
part number700-1006.

Be sure to drain a few inches of coolant before installing this thing
on your radiator (or pressure bottle) opening. . Keep watching the
tube as the car warms up and gases go through. If you have combustion
gas, the fluid in the tube turns yellow.

Now, about that head gasket...

Three or four years ago, I read on a Subaru forum the account of someone
who had experimentally but successfully used a CO2 detecting pill (sold
for detecting leaking house furnaces) to detect combustion gases getting
into the cooling system. Not a proven accurate method - I'd probably
use what you did if the need arose - just food for thought.

I just can't repost this enough times already. Think of the countless
hundreds of millions of dollars of the people's money down the drain and
hundreds of thousands of cars prematurely junked at the jumblers because
D-C design studios are jammed packed with darkies wo don't know sh.t from
Shinola. A multibillion dollar class action lawsuit to bring D-C to its
knees is just desserts for failure to heed my good advice presented below.
There's grounds just on the environmental costs alone, never mind the
people's money. Every car needlessly junked due to economic
unrepairability is hundreds of barrels of oil burned, a lot of metal
bearing ore, and a whole mess of pollution.
