The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

Car keeps overheating after driving only 1 mile or so. It doesn't always overheat but I never know when it is going to. I pull over and shut the car off for a few minutes and then start it back up and it is fine. My brother has changed the thermostat but that didn't solve the problem. I have also been experiencing leaks in the roof and also the dashboard. I bought the car brand new in Dec 2000 with only 4 miles on it. I love the car and it is perfect for all of my outdoor activities but lately it is giving me such a headache...
Car mysteriously started losing coolant. Checked the oil to find it had coolant mixed with it to form chocolate milk. Looks like car is end of life, time to shop for a new one.
replace thermostat because it was running hot, replaced climate temp sensor for the relay fans, replace bleeder screws, replaced radiator cap, still can get all air out from cooling system. dont know what else to try but compression test
No heat, took to Sears, was told it was my intake manifold gasket and that I need a new engine. Have not resolved the problem a of yet.
I began smelling antifreeze after every drive, particularly in hot weather. This occurred about six months after I installed a new water pump. I worked as an "A" mechanic for Sears and several other shops years ago so this is not an impossible problem. About four hours of work, several expletives and a skinned knuckle. Great time to replace those rear spark plugs too. In spite of this vehicle having a host of quality issues (all four axle bearings, rear end taking a dump, leaking gas tank and lousy response from the dealer and the list goes on), I really like the car and enjoy driving it. I have two other four other cars and have never had anywhere near the troubles this one has given me but the engine is top shelf in spite of the gaskets. Some may recall that the early Ford Taurus had a design flaw that caused a head gasket leak around 80,000 miles. Had one of those too but once you replaced the gaskets (11 hours and MANY expletives) I had another 120,000 miles of trouble free driving for about $300.
I was told that I will need to have intake manifold replaced. Coolant is mixing with oil. check engine light on. Will repair when I have the extra cash. Just did alternator. Trying to hang in without sinking in more money before I purchase a new car ...
i have a antifreeze leak under and behind throttle body. any help would be wonderful. ruled out all the plumbing, i used a pressure tester and the leak hisses out in this area. no coolant in oil. so head gaskets must be holding. maybe intake?
now it overheated and the lifters are rattling.
I am leaking a mixture of oil and coolant. Changed the water pump and thermostat and still having the same problem.
Overheated in 30 seconds and engine clunking noise. Pulled over and parked antifreeze in the oil.
Bought the car secondhand in 2009, started losing collant shortly after. Initially leak was small, no indication of coolant in the oil or vice versa. After a year, serious leakage occured from gasket near thermostat housing. Repaired at local shop. Shop also found radiator leak and gasket and radiator replaced, parts, supplies and labe came to $1200 for both repairs. Has run well since then.
coolant leak. replaced the intake gasket.
