Re: Oil pan gasket leak on new engine?
With all that RTV on it it may never seal without cleaning it all off. New RTV will not stick to old RTV. Also, RTV is not rated for use on rubber gaskets.
I had the same type leak on the front of mine with a one piece seal. I used Permatex 2B non hardening to fix it. I wound up jacking the motor up, removed all except the back two bolts which I only loosened, pulled the pan down, cleaned the rail with brake cleaner, cleaned out the bolt holes with q-tips soaked in brake cleaner, smeared Permatex 2B all the way across the front lip, put Permatex 2B on the bolts, and reinstalled all of them.
I can't remember but it seems like the small bolts get around 10 ftlb and the four large ones get 13 ftlb. The one piece gasket has inserts to keep you from deforming the lip by overtightening....up to a point.
