My car is idling at 650-700rpms and sounds/feels like it's about to die. Once the motor warms up and has been drivin for about 20 mins, it begins to smoke from under the firewall area which smells like burning coolant. Then when it's parked it leaves about a 3-inch spot of oil on the ground. Any suggestions? Should I just get my motor rebuilt?

 

what year is the vehicle, which type of oil cooler are you using? also, is it leaking coolant on the exhaust manifold or is it being burnes internally. if it is being burned internally, you have a bad water seal and your engine needs a rebuild. we can determine the cause of the leak if we have a location of where abouts under the car it is.

 

it's a 94. Using stock oil cooler. It's coming from the lower rear of the motor. I will check next time it happens and try to locate if it's external or internal.

 

Could be a coolant seal, you can bring it buy the shop and I can take a look at it for you. www.rx7store.net

 

yea, i thought it was a coolant seal, how much would you charge to take a look at it?

 

check your pm

 

The puddle could be from the oil pan. The sweet smell could be the ast or radiator. The smoke could be the turbos, downpipe, y pipe, and/or an oil leak from a loose hose clamp dripping onto a hot engine part.

Good luck...There are a million different possiblities.
