Slant 6 Turbo 68Dart Project

the video says private for the turbo. if you need to do a close up to show the play then i wouldnt sweat it. just check the housings for any signs that the blades got into them. fwiw, if oil is in the bearings and you were to try and check for side to side play it might not give if you dont do it super hard. way back when i had my turbo coupe i checked the turbo after running it for a while and it was tight, for ***** and grins i checked it a few days later when it was cold because i was in there and it had some play to it. as long as its not hitting the housings or really close to it i would run it. if you are afraid it might the rebuild kits are around $60 for a decent one. they are easy to rebuild too, just clean everything really well and put it back together the way you took it apart with the new parts.

no idea on the over heating. i had a slant do that to me years ago. just started over heating out of the blue. it wound up pissing me off because i couldnt figure it out and it was my dd with no backup so i cooked it and put another motor in. lol. took the tension out of the springs and it wouldnt run anymore. is the water pump original? the motor i have now was over heating on me when i first put the little turbo on. it started leaking from the weep hole on the pump though. changed that and its been good. might be worth swapping out the pump just for good measure and upgrading to electric fans. are you running a catch can? can you see the coolant flowing through the radiator with the cap off looking down in there? should be a decent flow with the thermostat open.

try putting the ignition box in the oven with an old pot under it. when that crap gets hot it will ooze. ive had them melt on me when they were on the fender so heat is definitely what is gonna get that crap out of there. also might wanna think about drilling some holes under where ever you mount it so that air can get to the heat sink. heat kills those modules.
