Coolant and oil mixing, gasket leak?
I have a similar issue. Not sure entirely but I'm pretty sure it is the intake manifold gasket either being cracked, warped, etc..I do all my own work to avoid labor fees and so I know how to repeat it again if a problem reoccurs. Only thing is, I'm not 110% sure though if it IS in fact the gasket. All I know for sure after checking the dipstick is that my coolant and oil are mixing. I just filled the coolant completely. Mind you, the car has been sitting for about 5-6 months and hasn't been started. I just shoveled off all the snow and got it running again today. Any input would be great before I pop the hood tomorrow and start working on it and fixing a problem that is not the problem. On top of that, GM said it should only take about 20~ minutes with proper equipment, which, I am able to get my hands on about 70% of that if need be. I will NOT take it into a shop because it will cost more to have done when I can just do it. I really don't want my fiance driving this daily until it is 100% fixed. And with the access I do have to the right equipment and what my buddy told me on the phone, this will take at least 2 days because I do not live at the house that the tools are at and we can't be there without anyone there. So I expect this job to take 2 days. Anything anyone has to say would be great before I "fix" a non-existant problem. :bang:
