A couple weeks ago I replaced the thermostat housing gasket, radiator, and water pump gasket. While doing so I pulled the CPS. Had a terrible time re-timing it. I followed these steps... http://www.supramania.com/forums/showthread.php?38775-How-To-basic-timing-instructions-CPS-alignment No matter if i turned the CPS ccw or cw a tooth I could not adjust quite to 10 degrees, 12 from one cps setting and 8 from the other was a close as I could get. Noticed my cam marks were slightly to the right of the timing marks. Ended up setting the crank to TDC and 0 deg; moved the cams back a tooth. Finally got the timing right. It didn't make sense to me that I had to move the cams back a tooth when the car was running fine previously.
I have a divorced downpipe.... Somewhere during all this timing I noticed alot of exhaust (mainly because of the increased noise) was coming out of my waste gate dump tube. Also noticed that at idle my boost was reading -15 psi, I normally read -23 to -25 psi. Didn't think much of it at the time. Took the car out and it would not build boost. I hammer down and the turbo sounds rowdy but it won't get above 0 psi and the car falls on its face.
Tonight I took the downpipe off to examine the rear of the turbo housing. I assumed I had the crack that often occurs on ct-26s. There is only the start of a hairline crack, and I was not leaking there or at the waste gate. Also replaced my actuator with one from a buddy which was tested before install. I left the downpipe off because I need to pick up RTV tomorrow. I fired it up and boost was at -15 psi again, so I don't have much hope for my test ride tomorrow.
Anyone have suggestions on what else to look at or check?
