Mike My head gasket is find the only thing wrong with my engine is cyl #4 I.  My truck turns on and everything Ive been driving it like that for around a month but just yesterday was confirmed that one of my cyl's is dead. It dosent leak or anything so I know my gasket is fine...Ive been looking at re-building kits from www.toyotaperformance.com www.lcengineering.com and AoR or something like that...but they were are sooooo expensive so Im still looking...while Im at rebuilding the engine Im thinking of might as well add some performance parts to squeze some juice out of my little 3.0....what parts could I replace and whos parts would I use?
