i have a slight oil weep at the rear of the sump (around the spot where sealant is advised to be used). this is with a brand new sump gasket and rtv sealant used (engine was on stand and faces clean/dry). sump itself is an ARE alloy dry sump -brand new. everything tightened down nice and easy and i used recommended torque settings. all the faces were clean and looked true.
i'm going to remove the sump and have a look , anyone got any suggestions or had similar weep in that region? maybe i didnt use enough rtv, but it was left to dry fully.
wondering if there is a specific sequence of the bolts also, i worked from middle out for tightening up.
any help appreciated
thanks

O.N.

do you use sealant or not back there i have sealant on mine now but it is a very small leak?

You guys talking about bolting up the Cover Plates with the Oil Pan?

O.N.

just the oil pan itself

i solved this by being very very specific about cleaning the faces, brand new oil seals, and sealant applied in specific spots where the front and rear covers mate with the sump. it all has to be lined up and flat, if the front/rear covers dont site right with the sump it will leak.
been bone dry for 2 seasons now.

Yup it all has to be lined up and bolted all together at once..I put a dab of RTv in each corned and never had any leaks.

I snug the front & rear covers on..bolt the Pan on tightening all the bolts from the center out criss-crossing, then tighten the covers from bottom-up criss crossing.
