Need some work on my 2003 Suburban

Sounds like it overheated and cooked the gaskets. I'd do a compression test on all 8 cylinders. If it fails the compression test, it needs another engine.

Ummmm, what? A few leaks constitutes a compression test? Lol.

What they quoted you is common on the 4.8/5.3/6.0 LS series engines. Literally all those parts, especially at that mileage will start to seep. If you aren?t seeing drops in your driveway, I wouldn?t worry about it. In order to get a true leak diag, you?ll need to degrease the entire engine, steam clean it and recheck.

The steering components on the other hand are likely due given the mileage. Don?t piece it together, just get it all done at once. Upper/lower BJ?s, inner/outer tie rods, idler/pitman arm, possibly shocks and it will drive like a new truck. You can also have them tighten the steering gear a few notches to really make the difference.

Well, theoretically, worn cylinders and/or rings can cause excessive crankcase pressure which could force oil out so it isn?t a totally irrational recommendation.

I doubt that?s an issue in the OPs vehicle though.
