It's the passage through the intake that gets clogged up. It will clog where the passage gets the narrowest. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

A can of aerosol air/intake cleaner and a coat hanger down the passageways; shame you went out and bought an EGR valve. But school costs money and we all have to pay our dues; I guess? Dan.
