Alright I posted this over at DSMtalk with little to no response, any of you guys can help out? I'd appreciate it
From DSMtalk: "Alright so I was getting a pretty loud ticking under acceleration and also some deceleration so I did quite a bit of reserach on here and figured maybe some of my lifters might have collapsed (1990 Eclipse GS-T) so I decided to pull them all out and clean them along with the rocker arms today. I got everything all back together and performed the cleanings per VFAQ. I pulled the MPI fuse and cranked the car for 30 seconds, and then started it up. LOUD lifter noise, im thinking OK its going to go away after a bit, 10 minutes later engine is warm and still loud tick, went out for a long drive, still loud ticks. Car still suffers from extremely crappy performance. Takes forever to climb the rpm's, takes forever to reach full boost, and in every gear after 1st, full boost is only 7 or 8 psi. WTF???? Is the ticking still so loud its causing the knock sensor to pull the timing? I have had this car about a month already and I've already swapped heads twice, and removed the b-shafts, and now this problem is occuring. " "PS-- If a lifter has technically "collapsed" will it never recover? All of the lifters I used were able to be depressed by the paperclip and flow cleaning solution as well as oil. Is this capability null even if the lifter has collapsed?" ALso one more idea that's popped into my head is a failed rocker arm. Could a rocker arm bearing seize and cause the clicking noise? ANyone heard of this happening? I'm about to my last resort of taking it to a shop -------------------- 1990 Nissan 300ZX T

I talked to eric w. and he is going to help me log sooner or later, I have to work Saturday unfortunately and I live in farmer city so it would probably be easier for me to travel to champaign (where I work also)
Also, after i assembled the rocker arms and lifters from cleaning them I pulled the MPI fuse and had a friend crank it over so I could listen for noise and i dont think the engine is turning quick enough for it to generate enough noise for me to pinpoint the problem area. I have a jampacked day tomorrow so it looks like earlier friday mornign im going to try and pull all of the accesory belts and see if the problem lies in the water pump or something like that (yes i know to start it cold and not leave it run long) Is it possible a cam "wore" creating a rough contact surface with the rocker arm and thats what's making the chatter? -------------------- 1990 Nissan 300ZX T
