Too much oil, only thing I can think of. Either that or your seals on the cap are worn.
Ther is a cap that says "oil" on it. If the cap says "710" it is upside down. The cap is located on top of the engine manifold and is labeled OIL. :-) Just look for the letters DOHC 16V and you will see it. Best of luck...
under the rear seat, round black cap in fuel tank, pump is inserted into fuel tank.
To open the radiator in your Hyundai Excel, first make sure the engine is cool to avoid burns. Locate the radiator cap, which is usually on top of the radiator, and turn it counterclockwise to release any built-up pressure. Once it's safe, you can fully remove the cap to access the coolant. Always check the owner's manual for specific instructions related to your model.
check your oil level?
More than likely 5w20. Check your owner's manual, the oil fill cap, or call your local Hyundai dealer.
the cap is open
The threads are worn and the vibration of the engine causes the oil cap to loosen. Replace the oil cap or try a little teflon tape on the male thread as a temporary fix.
Go ahead and replace the pcv
I have the same truck. Driver side of the engine, on top of the valve cover there's a cap with a hose coming out. Unscrew cap and add oil there.
Excessive blow-by (a tired engine) and/or the PCV system is not functioning correctly. Also, check the condition of the gasket under the oil fill cap.
They tried to clean it up but it kept coming out.
On the right side of the engine compartment there should be a hose coming out from the bottom of the motor with a cap on the end. (it looks like a hydraulic hose) Using a couple of wrenches, one to hold the line and one on the cap, remove the cap and the oil will start coming out. Pull the dipstick out to allow the oil to flow faster. Once the oil is drained put the cap back on, change the filter and refill with new oil. The oil filter is the one on the block just below the throttle linkage and the filter number at NAPA is 1068, use 15W40 oil.
