Car; 1993 190 2.3

Had recent blown head gasket/rebuild w/ valve job and subsequent broken camshaft (didn't know about them there ratcheting chain tensioners), had a large amount of oil/coolant mix that got into the block and cooling system. The problem I am still having is that I have a small leak out of a small hose that appears as though it comes out of the block somewhere exiting behind the alternater, but don't know for sure where it originates or its purpose. Have to add water/coolant weekly, what a pain. The car runs hotter than it should unless you are moving. At idle or stopped at a stop sign/light it heats up quick enough to cause concern. I am wondering if the water pump is going and/or did not get cleaned out properly and thus not providing proper cooling for the engine. Are these symptoms of a bad water pump?

Rick, ..try flushing out your cooling system using citric acid. This will remove the contaminated oil that mixed to your coolant. Also, ..try to bleed the water jacket, ..there could be some air present in the cooling system. Good luck....

Your water pump is gone. Its best to just replace it.

p.s the leak will get worse...and you don't want to be stuck with another blown headgaskette. That would be not cool! No pun intended
