Hey, gotta question for you all. I've got a 94 AAZ Golf. The only issue with that is that when I bought it, as is, off my cousin, it didn't run, and I knew that it burnt a bit of oil. After getting it going roughly 2.5 years later, I found out that it burns roughly 1 litre every... 100 km/60 miles or so, which is more than I'd expected. As you can tell that makes a pretty expensive trip, $6-7 on diesel... $5-7 on oil. In any case, I've narrowed it down to a couple of culprits, definately the turbo, and possibly the valve seals. Now to the question, does anyone know what tools, how much time, and more specifically what parts are needed to rip that valve cover off and check it out, then to replace it? If you've got a detailed list, lying around or know of one that would be great. LOL :wink:
you need to do a leak down test before you condem anything, this will tell you a lot about the condition of your motor.

Just as a data point, worn valve seals are actually a bit tricky to spot on a diesel... the old "puff of smoke on deceleration" tell-tale is often obscured by normal smoke from the engine itself, depending on timing, operating temperature, fuel tuning etc.
A compression test and/or leakdown test is definitely a more accurate way to isolate if you have engine wear that could account for oil consumption.
If it is valve seals they can be replaced with the engine in the car... in fact, because the diesel is an interference engine you don't need to use compressed air or rope to keep the valves in place while you remove the springs... the valves can gently rest on the pistons at the appropriate TDC.
Here's a home-made compressor that doesn't need a welder to build:
