Looking for some Tech Help Options

[Booztd 3]

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

If you are still using the stock boost control solenoid (bcs) connected to the ECU, it is possible that the ticking noise is being read as knock, so the ECU is pulling your boost back. During normal operation the bcs stays closed so the stock boost pressure of 11-12 psi is hit no problem. But when the ECU registers a lot of knock over a certain period of time it will periodically open the bcs to limit boost. If the knock doesn't go away it will keep the bcs open indefinitely to decrease the boost as much as possible.

If you want you can call this number for a great price 3rd revision lifters. 1-888-855-9712 Its a warehouse in Texas that carries the OEM Mitsu 3rd rev. lifters that are run in the 98-99 DSM's. I am running these in my engine and I can't hear them at all. The oil hole is much larger on these lifters.
