i took of the Cylinder Head out of my 4.0L and saw the beauty of a engine block and decided to turn the crank pulley to see how the pistons work???
is it bad, or meaningless?
everybody does it?
did i mess up with timing???


i'm worried that when i was admiring the pistons, i was also messing with the timing ...

will it be fine or not?
thanks everyone.

 

Did you take the distributor out?

 

OOPS i forgot to mention.
it's a 2001 jeep cherokee 4.0L inline six. AW4
i have the coil pack.

 

It's fine.

 

thanks man!
i'll go ahead and stare at it then!

 

Haha i just rebuilt my motor, pretty cool ,huh?

 

You're fine. If you DID have a distributor and it was out, head or no, of course then you would need to"index?" it. I believe the coil pack just uses black magic, not to worry.

 

Hah I did the same thing at the junkyard when my friend and I were pulling his new head off a 4.0.

 

i tooked the head and the intake manifold out to get them ported and man i don't even want to put the head back on.! at the moment i took it off i turned the crank pulley and saw the magic. ran inside for my wife and showed her the magic. she couldn't care less... lol
anyway it is awesome.


awesome. i'll keep doing it till i'm out of gas.!

 

it's awesome to see how it works inside out
1-6
2-5
3-4
i'm recording a video of it.... it's like watching a movie. but better

 

You have been possessed by the magic of the machine. You are now doomed to a life of empty pockets, barren wallets and angry women as you strive to satisfy the never ending urge to make it faster, better, higher.

Isn't life GREAT!!!!!

 

Haha, awesome quote!

 

When I had my head off of my 90 I turned the motor over so I could clean the crud off the pistons. Everything turned out ok when I put everything back together. I think the only time you need to be concerned is when your working on an engine with an overhead cam (ohc) where to dead center is an issue. On these Jeep pushrod motors I don't think it makes any difference about tdc.

 

you're right! i am possessed now! i am thinking of buying an engine block and stroke it out just for the fun of doing it, buy a comanche and throw it in.
it's Awesome.!

after staring at the pistons i decided to clean them up a bit like you did, then do more staring.

 

...wheres the video, I wanna see toooo
