Exclamation Oil port on back of heads leaking? HELP PLZ

Hey guys so rebuilt my engine and while i am building oil pressure i had oil start to leak from the back side of my driver side head!? I had shipped my heads to MMR to get ported and polished so i didnt touch the heads really.. just took them off and put them back on the head. The oil is coming from a bolt hole on the back side (check picture) does anyone know what goes here? is it just a bolt, or what? thanks for any help guys

Sorry the pictures are kinda ****ty very hard to get back there ha :P

There is a hole that is supposed to be plugged on the driverside head. It;s an allen key plug. Take it out and apply new thread sealer to it and put it back in.


If its pouring out and there is no plug in there then you put the heads on the wrong side. You will have to pull the front cover off and take the plug out ot the front of the passenger side head and install it in the back of the driverside head.

They can go on either side. You have to look at the plug to figure out which is set up to be the driverside.

x2 ... pull the cover and see if the plug is in the other head at the front of the motor. If it is, you need to remove it and put it in the back of the drivers side head.

The head are identical twins. MMR I'm sure didn't touch the plug. You just put the heads on the wrong sides.
