My 13B block from my 2, which I didn't build, has load-distributing brackets under the oil pan, running around the flange. It's a 6-piece set and goes between the bolt heads and the pan flange. Unfortunately, I've actually lost one somewhere, and looking to see if someone has a front-right bracket (front-left will work too). Were they original equipment on anything? All the 1st gens I've checked in junkyards just had bolts and an oil pan.

 

I didnt even use those brackets in my last 13-B install on a RX-2. I used mckenna brand silicone only; no gasket. They are much stronger than those silly tube ones from pep-boys or autozone. If you still want to use it, just fabricate a 2 long/2 short ones and dont worry about the corners.

 

Where did they come from? Where they original equipment on anything?

 

I will check tonight. I have an orig RX-3 motor sitting in my garage.
