SiriusBlack Posted July 27, 2021 Share Posted July 27, 2021 Hey everyone, I've got some new problems with my 87 GL10 Turbo XT. I'm hoping you all can help me out again. I pulled the coolant passage off the back of the intake manifold to replace the gaskets and the thermo vacuum valve as they were leaking coolant. To get it out without pulling the entire manifold I had to remove the turbocharger, distributor, knock sensor, and the throttle cable bracket on the bell housing. I just recently got it all back together and after some issues timing it (since I removed the disty) we finally got it to time at 25 degrees BTDC. Now however it tries to idle at 3000 rpm and heats up really fast and overheats despite my upgraded dual core cooling system. We haven't done tons of troubleshooting yet, just looking for things to try while I do so. It ran like a dream before I took it apart for the leak. Any suggestions? Thanks in advance.
