ok so i got a 98 plymouth neon DOHC and i blew a head gasket on it so i recently fixed the head gasket but for some reason i am leaking water and oil really badly now. i checked the pressure on the radiator to see if it was leaking and it held pressure with no leak after 30 mins but once i start driving it doesnt take but 10-15 mins to start smoking and overheating. and im not sure if the oil leak and water leak are connected anyone else have any info on it i would appreciate it

When you replaced the head gasket, did you have the head checked for being true and not warped. If the head is warped she will leak.

Hopefully its not a warped head, but...
If the head was warped enough, you might have coolant being pumped out with overheating resulting when the engine was running - due to the warped head. Doing a radiator pressure check wont necessary show up such a leak. The radiator tester works at 16-20 psi. The pressure forcing gases past the headgasket peaks at over 1000 psi in an engine running at moderate speeds. The engine head on a Neon has an oil passage that is very close to the edge of the gasket, so motor oil might be getting pushed out also.
I wish you luck...

i got the head checked its fine. i will have to check this spot next to the head for the oil leak so far i havent been able to find it. i just see it dripping under the car. but i think the oil is coming out of where the power steering fluid container is bolted into the the engine

where is the water comeing from ..... nere the timing belt ..... it could be the water pump ..... if it only leaks when driving
