Hello. I am posting this thread here and in the YJ section because I really need some help as soon as possible.
I am in the process of doing a head swap 4.0 onto a 4.2 and doing the MPFI conversion at the same time.
I set the engine at TDC and took the distributor cap off confirming that the rotor was pointed at number 1.
so I pulled the head. then I checked the timing chain and found it had a bit too much slack so I pulled the harmonic balancer and the timing cover.
when I pulled the timing cover I found the crank sprocket positioned with the dot toward the cam sprocket. the cam sprocket dot however was 180 out. I rotated it around so the two dots are aligned. here is the pic.
however the rotor looks like this.
now keep in mind this engine was running just fine when I took it apart. but this as far as I know looks like the distributor is in 180 out of time. I called Hesco and asked them about it and they said to just re install everything like I took it out.
so I swapped the timing chain. it looks like this now.
the distributor looks like this.
before reinstalling the head I rotated the engine so the cam sprocket was at 1:00 and the crank sprocket was at 3:00 and counted pins. 15 count just like it should be. reinstalled the head, torqued it properly.
now I need to pull the distributor
. the new distributor has a pin in it to keep it from rotating. My concern is that this looks like it is 180 out to me. should I reinstall it like it was? I know it is not that big of a deal to pull the distributor and swap it 180 but I wanted to get some more opinions before I pulled the distributor.
so anyone out there have any opinions?
