Hi people,
Just wanted to share my recnt hippo exploits.
My hippo had been smoking quite heavily (black smoke not fags!) and was unstable at idle so I decided to tackle the EGR Valve. After weighing up my options, remove or clean it, I decided to keep it and clean it.
I removed heat exchangerfrom the valve then tried to remove the valve itself but someone had already rounded off the allen key bolts leaving me no option to leave the valve in situ.
Armed with lots of carb leaner I doused the internals of the valve and flushed out the mucked up heat exchanger and pipe to inlet manifold.
I was concerned about the valve seating properly, so I used the actuator pipe and applied suction to lift the valve seat up and got lots of lovely carb cleaner in to make it spotless.
After re-assembling the results were instantly noticeable- more torque at low down revs and after the first mile much less smoke and overall a smoother happier engine.
Its cost me £3 for the carb cleaner, 30 mins of time and with keeping the valve I get faster warmup and the economy benefits.
Happy Hippo Times again!
