Project AE86: One Step Forward, Two Steps Back

Well, no one said life was always going to be easy. Found out the hard way, the motor on the AE86 is no good. Pretty bummed and disappointed about the outcome.

As the tuner was setting up the dyno, and adjusting the ecu setting, she started to smoke under load. Didn’t even get to do a dyno pull. The tuner was thinking originally its from the header wrap but the smoke was coming back form the exhaust.

The 2nd video shows how bad its was. She revs up, but its just ticking time bomb. Thankfully no rod knock but if we pushed it, she might have gotten to that point, or even worse and blow the motor. We canceled the tune and did a compression and leak down test.


Cylinders 2 and 3 are in very bad shape. Lesson learned, always do a compression test before buying a motor. I did see metal shavings when I did an oil change, and smoked a bit on idle, but I didn’t think much of it. All I can do now at this point is rebuild this motor or get a good motor and swap that… Life teaches you things, and you learn from mistakes. Can’t give up now.
