Engine Oil in Coolant and Coolant in the Engine Oil
If the head gasket in your car fails or you cause a failure of the head gasket or cause a crack in the cylinder head from running the car when it is overheating, then engine oil can escape into the coolant passages in the engine and coolant can escape into the lubrication system in the engine.
From what you have described you have some very expensive repairs to deal with.
1. You will need to determine the cause of the engine overheating. It may be from combustion gasses leaking into the cooling system via the head gasket or it may be from a range of other causes such as a faulty thermostat, a failed water pump, a blockage in the cooling system etc etc.
2. From what you have described, the cylinder head(s) will need to be removed and inspected and checked for soundness and any cracking. The valves will need to be inspected The head gasket(s) will need to be replaced.
Most likely a blown head gasket or cracked head, maybe both.
SOURCE: Water mixing with engine oil
Yes I have. The 5.7L Vortech and the 4.3L Vortech share the same problem with the intakes. I just fixed another one recently. I will either lead and the front dr. side corner or the rear pass side corner of the intake. The replacement gasket set are far superior to the stock set.
SOURCE: Oil engine oil mix with water
sounds like you have a problem with the head or head gasket.Pulled out the spark plugs and see if you have any showing signs of leakage from head/gasket.
SOURCE: engine oil mixed in coolant
this would more than likely be cause by a bad cylinder head gasket. I would bet 89% this is your problem.
SOURCE: water/oil mixing in 22r engine
yes it can mix, also check the timing cover for rubs from the timing chain. this is the common problem with 22r. many mechanics will tell you its the block but they are just trying to make money.
SOURCE: 2000 Boxster overheating, blowing coolant out of
Whatever you do, do not drive.
I got the same problem about 4 hours ago and tried to get home.
Half way, no oil pressure, overheat, silly noise from the engine.
Take your Boxster to a shop with a truck, you'll save money.
