I recently pulled the head on my '95 Neon, DOHC 2.0. I had new valves installed with guides, seals and the head shaved to square it up. I used all new gastets when assembing the engine, but now I have an oil leak on the right rear of the engine. I don't see any oil on the exhaust manifold or smell oil burning. I see oil on top of the alternator bracket, but CAN NOT find the actual leaking area. I have laid under the car while it was idling, sprayed brake clean and for 30 minutes I could not see a leak. I tried a new valve cover gasket, with sealant and it still leaks. I have tried a new oil filter and checked to be sure the oil pan bolts were tight. Sometimes the leak is really bad and sometimes the leak stops, then starts again. I drove 100 miles and no leak, then I drove 50 miles and it leaked half a quart. The oil gets on the right side half shaft, so I don't know if the leak is down low and the shaft slings the oil up higher or not. Has anyone experienced this before with a Neon? I am about ready to blow this thing up. Does stop leak work? Does dye help? Any help would be greatly appreciated. :evil:

I would not use any stop leak additive of any brand.
Dye does work.

check your cam sensor, bad for leaking oil. Hard to see the oil leaking form the buttom of it.

The cam sensor on a DOHC cam Neon engine is on the left side.

The cam sensor is on the left just one thing to check, but have you check to see if the timing belt is getting oil on it if so check cam seals or crank seal maybe pushed out or not install right. I've seen cam seal not install at all form the shop were get the head work done. Just things to check.

Yes, the timing belt, plus the other belts too, was one of the first things I checked to see if oil was getting on it. The belt is dry as an old bone, plus I don't see any oil at all on the back side of the timing belt cover. Is it possible for oil to leak out of one of the power steering resevoir mounting bolt holes?

Discounting Murphy's Law, is it possible to put the head gasket on a Neon engine incorrectly causing it to leak oil?

It is possible to install head gasket differently than designed.

One method I used to find a leak after cleaning off the engine squeaky clean and dry, was to drive the car, then sprinkle Aunt Martha's Flour on it.
Where the flour stuck is the leak.

no on pwr str. head gasket were a problem for sohc and dohc. new gasket should have been 3 layers steel sheet in the middle they did that to fixs the head gasket problem. did you torque the head to spec. you have to torque the head in steps. as far as putting the head gasket on backwords i don't thing so, its been a long time cent i worked on 1. you could have messed it up putting head on. 1 other thing 2 check is the pcv valve may not be working or clogged.
