I noticed the other day oil pooling on the chassis and investigated, it appears to be concentrated on a couple a screws on the chassis below the front and rear differentials (please see attached pictures). I assume oil is leaking from the differentials for some reason.
I am unsure of the cause of this or how to fix it and would appreciate some help to trouble shot this problem. My apologies this is the first car kit I have constructed and I'm new to the hobby.
Regards,
Matthew.
Did you use the blue gaskets when you built the diffs? Or maybe over fill with oil or maybe over tighten the 4 small diff screws? Was there anything left over from the packet when you built the diffs? Maybe look again at the build instruction manual in case you missed a step.
