Well, mine used to have this problem...but, this morning I took it to my local Acura dealer and had my friend work on my car...he replaced a piston, and all the seals and rings on the others...took care of the problem!! Now to get the rest of my problems taken care of...timing belt package change, and the 105,000 mile check! He's also gonna fix my rattling muffler! He does good work and saves me a ton of money! He's doing the timing belt and all of that for 300!!
