I was getting an intermittent oil pressure warning light which was more persistent at higher rpms. I was not able to locate a pressure gauge as is recommended in the fsm, so I drained the oil and did not notice anything remarkable as I watched the oil flow out, but when I pulled the pan, was dismayed to see a very small amount of water in the pan. my first reaction obviously was <img src="/forums/images/graemlins/scared.gif" alt="" /> "blown head gasket!?!?" but when I rolled the oil around in the bucket, did not see too much in the way of water in there. the amount of water in the pan was maybe 1 ml and i'm guessing that the total amount in the system was maybe 4-5 ml (almost a teaspoon) so my question is: if there was water in the oil at any point, how long could it be kicking around in the sytem? because there is evidence that that water may have been in there a while. (rust stain in the oil pump housing, slight amount of rust in the pan etc.) second, could a small amount of water deteriorate viscosity enough to result in a low pressure warning light? <img src="/forums/images/graemlins/confused.gif" alt="" />
