Compression test

Testing cylinders individually and purchasing all the tooling yourself will let you know which cylinder is having problems, but the head will need to come off regardless if you've got high blowby that isn't coming from a compressor or turbo.

That's a really good idea, attach a manometer on the crank vent and use Insite to run the engine on one cyl at a time and record the results.
Not only simpler, but far less labour intensive and probably less expensive tooling...and, can be done at much closer to, if not at operating temp for best results.
