Car Forum / Isuzu Cars / April 2006cleaning EGR valve
how can an EGR valve be cleaned? it comes off easy on between intake and exhaust manifold and the intake side port is full of soft oily sludge but I suspect the port should not be sprayed with any chemical as that would move inside the intake is there any way to determine if EGR is stuck open and if it is, how can it be closed? > how can an EGR valve be cleaned? take off the 2 bolts and the exhaust side bolt and slide it out carefully avoiding damage to the gasket spray inside the intake and exhaust sides some liquid wrench, let it soak and repeat a couple times don't spray the valve on top where the vacuum line connects you can use a small brush to carefully scrape the channel between egr and intake manifold but don't spray inside |
