Hi All,

First post here, I have tried searching but can't find anything relating to this query.

I have just removed the Exhaust Manifold off the GQ RB30 as it was leaking / noisey.

The what I think is the EGR pipe that goes into the end of the exhaust manifold was so tight / rusted that it was unable to be undone. I ended up cutting the pipe clean enough that I could rejoin it.

On inspection it looks like the exhaust manifold is cracked so I will need to replace with one from a wreckers or buy a set of extractors. Does any one know if this EGR pipe is needed for the engine to perform correctly and if extractors on the RB30 makes much difference?

Thanks in advance

Luke
