leak oh crap

[74bluecharger440]

Just had  a new Holley and torque converter installed at the shop..Now I've got an oil leak it seems to be at timing chain cover. I spent so much at the shop I think I will take this one on myself..So by the look of it I  have to  drain rad and oil the disassemble everything up front,,The car aside from leaking launches  and lites up the rear tires like never before. won't have to oil spray the underneath of the car now.. I can already feel my back aching just thinking about starting this...Or should I let a mechanic do it rather than myself..  What would it be  3 hour job and gasket kit????Okay not going to wrench  on fathers day going to clean up the ram and go to local car show ..
