i took off the intercooler & the tb. The TB needed cleaning. The right side of the motor was wet from oil front to rear. I didn't snug down the valve cover.I tighten it down & took it out. This time I went WOT from 3K up to 6K in 3rd & 4th WOW! It pulls hard from 3K and pulls real strong all the way up to 6K I think I hit the rev limiter. I've never had a cam pull so strong above 5K Sweett It's a nice smooth idle. After 23 years of working on this car I now have the SVO I've wanted.
