Thanks for the tips.
1. I would love to do an LSX swap, but I have a pretty full plate with car projects right now. I did a google search and I saw it has been done, but I think I would do a turbo on the m104 before I went that route. I thought the M104 AMG motor would be a cool swap, but probably not worth the cost/HP/Hassle.
2. I did a leak down test on cylinder 1 today (the one the seller told me was bad). The first time I tried the test I had 80% and I couldn't find where the air was going ( no air coming from the dipstick, oil filler cap, or radiator) so I assumed I was on the exhaust stroke so I rotated the engine until TDC again.
This time I got the same result...about 80%. Still couldn't hear where the air was going so I pulled spark plug 2 and 3, and air was pushing fast out of both of those.
That seems crazy that it was 2 and 3, so I'm wondering if I'm just doing the leak down test wrong.
I did the leak down test on # 2. It was showing 80% but than after 10 seconds or so it climbed up to 20%.
I'm not really proficient with a leak down test though and I'm wondering if this gives any clues, or if I need to go back and do a compression + leak down on all of them. Also, should I pull the exhaust manifold to make it easier to see where the air is going?
Thanks for the help
