There's always a sense of satisfaction when doing a DIY successfully and saving all that money. Also congrats.

Your Monty is identical (color/trim) to my 1992. If you ever want to sell it for parts, let me know. I used the valve seal disassembly opportunity to send the injectors out for testing/cleaning to Witchhunter and to replace the PCV valve.

You can easily use the hose from a hose style compression gauge to hook up a compressor. I also made a shut off ball valve adapter with plumbing fittings and an air gauge to do leak down test at the same time, but this is an option. If you have excessive leak down you'll need a good size compressor to keep the pressure up. You'll also find that water will enter the combustion chamber from the compressor so make sure you change the oil afterward.
