ok, so I started to pull apart the motor to replace the base shims..
where is all this oil coming from? my head nuts were loose, I think the oil was coming from the head stud to the case? anyone else run across this?  it looks like my cylinder was leaking also...  |

ARP studs,
finger tight in case, I think I forgot to use sealant on them..  cylinder base shim looks good, no leaks, oil pump looks good, no leaks, galley plugs look good, no leaks.. I am running a little rich though... (IMG:style_emoticons/default/dry.gif) |

Do I or don't I...........? Group: Members Posts: 5,900 Joined: 24-March 06 From: SE PA, near Philly Member No.: 5,765 Region Association: North East States |
Did you torque the heads in the proper sequence?
I didn't & have cylinder head oil leak after 20 years ( minor, but major on a CW car). Took a shortcut - got burned. It DOES leak. It DOES make a mess. I AM stupid. I WILL fix it this spring. DUMB, DUMB, DUMB. Got expert advice. Didn't listen. Paying for it now. Anyone know if you can change this seal/gasket without removing the motor? Apologize for hijacking this thread. Pat |

Herb, It can also be a leak somewhere about and just leave the trail there due the movement on of the air. Found my oil leak last year - the top of a valve cover! Make sure your's are flat.

Matt, mine are flat, I also welded in a support to the gasket on the inside...remember my trail at NHIS??
I for sure had a cylinder to head leak, I am thinking that due to this I might also have been leaking out of the head stud to case area. It might be hard to see in the pictures..thanks, |

Welding can cause warping in the valve covers.
Pat: Save the headache and remove the motor. You have to pull all the injection/tin off, not to mention that I doubt you could remove a head with the engine in the car. Don't solve a shortcut with a shortcut. (IMG:style_emoticons/default/tongue.gif) |

mark, motor is already out....
I did talk to Charles about the torque... he did mention doing a re-torque. I guess I never did that... I also cc'd the heads...does 80cc seem right??? look in the picture above..pretty deep cuts and port work...very large valves... |

80cc per chamber doesn't sound right. Sure it's not 40 and 40?
Check your rings. I've taken apart a few engines (not alot, i'm still a noob) that showed leaks similar to yours that had broken rings. |

cylinders are coming off to replace base shims...
cc yes to the bottom of the relief...80cc's I need to verify, this is a 103 motor, but this drops my CR to around 7 or 7.5....no good... |

I don't know if I'm comparing apples to oranges here, but my /6 leaked from between the cylinder and case when the head was loose.
