I did a leakdown test on my engine out of the car, even made a video for you (black midyear targa clan whatup!):



This was a harbor freight leakdown tester so it's a POS, but the approach is the same. As said above, I bought an OTC one and unloaded that HF one on ebay to some sucker for $20.

I have some videos on valve adjustment and stuff too, hope they help. Definitely do RSR seals while you're in there. DEFINITELY do RSR seals. Also do RSR seals.
