yes it can and if you have aluminim heads with a cast iron block you need to put new bolts in as well
Do you have an oil cooler? I have heard that is a possible cause, as would be the head gaskets.
I'll ask a question. Is the low coolant light on? Coolant O.K.?Gm's V6's have a bad habit of using coolant due to faulty intake manifold gaskets?Might want to start there. There was a recall or some type of ruling on the gaskets from GM. Good luck.
the intake gaskets on these motors are known to break and coolant will run along the intake and head down the back of the motor.
I'm assuming your grand am has a 3400 v6 which are known for intake and head gaskets leaking. so its possible that one of those gaskets are leaking so bad that coolant is leaking from intake/heads down onto your valvetrain and then down into your oil pan. more than likely its your intake gaskets leaking.
The lower intake gaskets have most likely failed, and you are very low on coolant or there is air in the cooling system.
Also losing coolant i believe. That would most likely be head gaskets. And hopefully only that.
There are hoses, gaskets amd water pump which cause leaking. Check it out where the coolant is comming from.. The speed sensor is probablu bad.
Sometimes, when head gaskets go bad, the coolant will be burnt off out of the exhaust system. That may not be noticeable at all.
check your water pump. As well as your thermostat housing, and any coolant hoses/connections.
No It would not unless beside that plenum on your block is a crack in your heads and your leaking coolant or even leaking internally check head gaskets
lack of coolant . no cooling fan operation, low engine oil, improper coolant mixture, thermostat stuck, debri on radiator , restriction in cooling system.
it is possible for heat from combustion to cause an engine to overheat quickly depending on where the gasket is blown, but i would look for a lack of coolant circulation first. if your coolant is not getting out of the motor and into the radiator it will overheat very quickly.
