So I bought this ride, it's an 86 5 liter $700. The owner apparently didn't know what was wrong with it! I'm sure he did, but the car is wicked clean.. I ran through timing, made sure there was spark and fuel. Rough turning over. Finally realize that the crankshaft had about a quarter inch play. Previous owner told it was some sort of crate engine. After digging around I realized the Comp Cam heads. Rockers, alphabet cam and Scat 347 kit. Crankshaft was split in 2 after the first main. Metal particles wear everywhere cylinder walls were damaged. Parted out the engine.

It's an 86 with a 87 and up front. Sold the front and Hood to make way for 4eyes.

So due everything going on in the world today, I managed to find a 90 hatch being parted out. The hatch was still running when I went to remove parts. Got the ECU A3M entire connecting harness with the engine harness $60. Also got the fuel tank with pump assembly and lines.

By the way, I put together an explorer motor for a friend. Nothing crazy. Gt40 setup. did add a b303 cam, 1.6 rocker, dual valve springs and Edelbrock intake.

I'm curious is if the 90 engine harness will work on the 86?

How much of the old harness is there?

How much of the old harness is there?

The only harness I was missing was the engine harness salt and pepper connection. Everything else was there. I keep on finding pinouts for 87 and up not for 86.

I already converted to mass air. just waiting to drop the motor in later on today.

So it's running like a champ. Only problem is that my PCV which was new broke! And the crank pressure is coming ove the vent tube on the valve cover! Any ideas?

 

[General karthief]

Not until you replace the pcv, is the screen clean?

 

[86vertstang]

Yes, screen is hella clean. Seems like steam puffing out the oil filler. Seem to hydro or vapor lock?!!!?!
