Offshoreonly.com - Mesa Balancing Racing Engines Bottom ends from Inside out

Ok guys I hope everyone is doing good todays update is always a subject here on OSO as a matter of fact a couple of weeks ago it was being discussed. Oil pan to pick up clearance here are some pictures of how we do it there's more than one way like everything this way you don't need any special tools and anyone building their engine at home can do it.

Install and torque pump and at the same time install the gasket you will run and seal it to the block.

Install a piece of tape to the screen as to not get it contaminated with the clay you will need to transfer the clearance . Note set the clay all the way across the surface of the screen to make sure it sets flat across the bottom of the pan and it's not blocked on one side or the other. Set the pan over the top and tighten it as it will be on the engine. Remove the pan and measure the thickness of the clay. At this point you know what the clearance is we run 5/16 or .312 to 3/8 or .375 . Note on marine engines with 10 to 16 quart pans you can be a bit more but never more than 1/2 or .500 . Automotive small capacity pans you don't have that luxury you will eat up a motor in a NY minute . Never run the pick up in any application closer than 1/4 or .250 from the bottom of the pan because you will start to see oil press problems and inconsistencies below that under sustained RPM. I hope you guys like this post I know this gets asked so many times here and what's best is the simplicity of how we check it you can go crazy and pull out a dial caliper and measure the height of the pick up minus the height of the oil pan and add the thickness of the gasket which is crazy ,1drop the pan over the pick up 2 tighten and pull off 3 measure and you're done. Simple as 123 . Hope you enjoy Laz
