Thanks, Navy!

Here’s an update on preparations for the next road trip.

Had two oil leaks on the engine. One on the adapter that feeds the Accu-sump and one on the right valve cover.

The adapter leak was fixed by installing a new adapter. The original one was bought from an independent guy on another forum with a CNC shop that was trying to break into the LS parts business. The part looked well made, but leaked where the -10 fitting threaded into the adapter. I even recut the o-ring seat myself in an attempt to salvage the part, but it didn’t work.

The new part was made by Improved Racing and seems to have fixed the problem. Replaced the adapter when I changed out the original break-in oil. This was the second oil change, actually, I changed out the startup oil at 50 miles, cut the filter open. Everything looked good.

The old adapter:



And the new one:



BTW – I would have never thought that finding name-brand non-synthetic 5W-30 oil locally would be so difficult. Four different parts chains didn’t have it and WalMart didn’t either. It simply does not appear to be sold in my one-horse town. I did find some 10W-30 Comp Cams break-in oil that is regular oil. Looks like I’m going to have to order it. I don’t want to run synthetic until I get a couple of oil changes on it. Looks like I’m going to have to order dino oil online! And, it takes slightly over 7 quarts to change it out with the Accu-sump.

The valve cover leak gave me fits. It took 2 attempts to get it sealed. I discovered that the Holley valve cover adapters that I’m using have to be pushed up on the mounting bolts as far as you can to get the lower rail to seal. Wound up making a couple of long, threaded dowls to help position the covers while installing the regular mounting bolts. I also trashed the Holley cover bolts and installed some original LS bolts. They seemed to work better.

I cleaned the oil off the bottom of the car and inspected everything I could get to. Discovered that the driveshaft u-bolts were slightly loose. Not sure how that happened. I must have just snugged them up and forgot about them.

I still need to recheck the front ride height and it would be nice if I could get it up in the scales and check corner weights.
