Hi kwstine86, Welcome to 2carpros and TY for the donation the site appreciates it to keep helping

You need to perform a combination tests -check the engine compression both wet and dry tests and follow it with a cylinder leakdown test. Doing this will pin point where its leaking could be valves/rings and cylinder wear
