Marbles..Something you said earlier brought back a memory -

When you mentioned it sounded like air leaking and something was seriously wrong - You thought a plug was going to blow so you checked torque.

So far, I had #8 , #1, and #4 go out on me. The first two (8,1) went out normaly they were diagnosed and fixed.. When #4 went , holy crap - I thought I blew it up, The motor made so many noises and I remember the air leaking one. That was strange, none where loose, I'm not sure why it made all those noises to this day - The others didn't - but that's all it was..COP#4..That was along time ago.

I'm telling yuh - get your #5 to fire first before you waste a hell of allot of time and money..
