First I really I don't know where put this (Maxx trucks or here)
I was driving my T-Maxx 3.3 and I see the engine running very lean and I see like a air leak and nitro-oil coming out form the engine on this part:
I think is the o-ring from the header
My questions are:
1-What is the size of the o-ring?
2-What is the o-ring # part?
