Re: Rebuilt 4.7...Will not idle

No worries. Just ordered a new timing set. Hopefully have it back up soon.

Re: Rebuilt 4.7...Will not idle

Here attached the procedure for the timing chain adjustment, if you donīt have it. It seems that the colormarks on the chains only line up when first installing them.

Re: Rebuilt 4.7...Will not idle

Well I finally had time to replace the timing components. Everything was lined up perfectly this time around. Get everything back together, go to start it and guess what. No change. Still idles like complete shit, have go give it gas or it will just die. Haven't checked the plugs yet but I don't know. I'm feeling pretty rough right now, I was really hoping this would do it.

Make sure you don't have a cam follower that may have popped Off. Pull the valve covers real quick and check.

Re: Rebuilt 4.7...Will not idle

Depending on how far of the timing was, there is a possibility that a piston(s) has hit a valve(s). It seems that intake valves can easily be hit by the respective pistons, when valve timing is incorrect. Did you do a compression check on all cylinders already?

Re: Rebuilt 4.7...Will not idle

No, I have not checked compression yet. My tester decided to stop working so I need to pick up a new one. The first time putting it back together I made sure there was no piston/valve contact, everything was smooth. I am thinking it's something valve related. Is checking the cam followers fairly straightforward, I've not messed with head's yet.

Yes, if it's off out will literally be sitting at the base of the head.

Re: Rebuilt 4.7...Will not idle

The IAC is new. I have also cleaned the throttle body, no change. I still haven't had time to go back and check the vavles. Hopefully get a chance in the next couple of days.

Drivers side valve cover comes of in like 5-10 minutes. Passenger is a little tight in the back but still not bad.
