      Haha yeah it’s pretty sweet we are still having trouble making boost, got a couple leaks we need to tame. Aiming for just ab 5 psi until we run out of injector and hoping the 4t65 holds up.  more videos coming soon once it’s nice out

      Do 3100 v6s have metal head gaskets? i am replacing the LIM gaskets on my 95 grand prix se and was wondering if I should replace head gaskets as well as a preventative? Do the head gaskets on early 3100s have common issues? I read that the heads tend to warp when overheated (my car was never overheated) but is the gasket itself a multilayered metal gasket? I would assume it is because the bolts are TTY, but I have no idea and cant find any other posts stating what type of gasket it is.

      For what it's worth, I really appreciate all the advice, guidance, and well wishes to get the old girl up and running again. I just really don't think being told to let someone else do the work for me was necessary based purely on the fact that I don't own or rent tools that, frankly, I've never needed. That said, somewhere along the way, I screwed the pooch. After removing the plenum again I've found I left a throttle wire disconnected and a vac line from the fuel rail to the back of the plenum (fuel pressure regulator to the map sensor I believe) disconnected as well. The plugs are also fouled. In addition, since the plenum was off I pulled the valve covers to make myself feel better on the timing. I'm off on the rear. The front appears retarded by a cog spline, maybe 2. I wasn't diligent enough when I checked the first time. The rear appears to be the worst. The one nearest the firewall appears dead on. The other retarded by about 3 cog splines. I really can't explain it. I definitely got my work cut out for me

      how was that response unwarranted? He's trying to point you in the right direction on what next to do to diagnose. Unless I missed something you seem bitter about nothing. A lot of us have been here for years and want to help the new guys, dont get your panties in a bunch because your ego was a little hurt   Check what these guys are saying. If you have fuel pressure, is it getting to the cylinders? Could be some blocked injectors, could be injectors not firing. Check the plugs to see if they're wet, maybe you have fuel but no spark. He asked about your tach, check that, maybe you have a bad crank sensor or something.   This may be a dumb question but I've done lots of dumb things: did you plug all the injectors back in after doing work? All the connectors that you unplugged? There's just so many variables it's hard to say, just have to start checking things one at at time. Good luck!   I read your last post again, if it runs but rough it sounds like you're not firing on a cylinder or two. One at a time unplug each spark plug and try and see if you can start it and if it behaves the same. Might be able to narrow down where the issue is

      I have an engine support bar ordered to try to make things as easy as possible. I’m adding subframe bushings to the project, too, along with a new trans pan gasket and filter swap. I don’t need to drive the car so I might as well do as much as I can!
