2001 Elantra symptoms.

Has 98k miles. If I take off the oil filler cap when
the engine is idling I can a pulsing pressure like there
is an air(?) leak. The engine has plenty of power on the
highway, over 80mph in 4th gear(5speed manual)
I feel there maybe gasket trouble, any ideas welcome
before I take it to a mechanic.

If it,s not using any oil I wouldn,t be worrying.

Depending on the amount of pulsing, this is a pretty much normal condition = caused by some of the combustion pressure leaking past the piston rings. A= better test is to remove the oil dipstick and start the engine. If there = is slight suction overall (rather than pressure) there is likely no problem= . That indicates the vacuum from the PCV system is greater than the amount= of blow-by.

Thanks for that information, makes sense.
