If you put a BP together with oem rods your gentleman's sausage will fall off.

So a couple questions, how the hell are these wires held in. I can tell they are stuck there but can’t figure out how to undo them.


Also, can I disconnect the exhaust manifold from the head and get the engine out and leave the exhaust manifold in the car? I was able to get those nuts off, but the 3 that are further down the exhaust that you are supposed to release according to the guide I’m using are totally rusted on.

Ok, that wire bundle is pinned to the trans tunnel, but IIRC you leave it behind with the car when you pull the motor. Disconnect the starter and alternator and... Yeah. Everything else.

Regarding the exhaust: probably gonna have a better time removing it. You're gonna want it out of the way when you drop the motor back in anyway. Unbolt it at the front of the cat and remove the one bell housing bolt that holds the down pipe bracket. Also pull the O2 sensor. Then just pull the manifold and down pipe as one. You have to rotate it as you pull it, but it will come.

Also don't forget to disconnect the clutch line and the Speedo cable.

The problem is that the bolts by the cat are totally rusted stuck. I tried penetrating fluid, heat, a breaker bar, a breaker bar with a cheater bar, and finally an impact gun. So my choices are either try to get it out and leave the manifold in the car, or idk take a sawzall to the exhaust.

Just go medieval on the cat bolts. Replace with stainless if you twist them off. If you can't twist them off, your cheater bar ain't cheating hard enough.

I just unbolted the exhaust manifold from the head and left it all in the car. I wouldn't want the manifold in there when putting the engine back in but I found it to be a lot easier to deal with the exhaust bolts once the engine was out of the way.
