jenkies mate, spray with wd40 and let it sink in. We had the same problem with my bro's r32. got a big screw driver shoved through it and turned.
good luck tho.
with mine and my mates, we just covered the pod. Got some degreaser and wipe on with a rag. After that we got the pressure washer and sprayed down everything. (just dont go spraying electrical components for ages)
Car started first time no worries.
