I have a'99 G3500 express van with over 332,000 miles on it .I live in a cold climate and the other morning when starting up there came a sputtering sound beneath and when i got out to check it i saw a large amount of oils gushing from near the filter. As i live in a Condo Complex and am responsible for the condition of my parking space i couldn't let it run to see exactly where the leak was coming from but it generally looked like the filter. I shut it off checked the filter, tightened it some and tried again with the same result , gushing motor oil.I went to the parts store and bought oil, filter, drain pan and a filter wrench and put on the new filter added five quarts and when i started it it happened again after a few seconds oil began gushing out from near the filter. I have a few questions before i have it towed to a garage. The night before i parked the car last before this happened about ten minutes up the highwy from home i added some stop leak fluid to the radiator as there had been a slight leak of coolant. Is there any connection whatsoever between the cooling system and the oil system which could result in this rupture if say the stop leak pellets are clogging in the coolant system?If there is none what is up and behind where the filter screws on that may be the source of the leak? I haven't been able to look while the engine is running and as i put a brand new Fram filter on and the same thing happened i am unable to identify the problem. If i could fix it myself i'd rather than have it towed. It has since snowed and is very cold out now so i'm not inclined to get out there to try but when it warms up some i have the drain pan i can use to collect the oil as it spills and run the engine to perhaps see the problem though getting a face full of oil doesn't sound like much fun. Any good answers will be very much appreciated Thanks.
