O2 sensor code, lack of power and back pressure which is pushing smoke out of the valve cover?

Check that your catalytic converter didn't collapse inside causing a severe exhaust restriction.

Causes lack of power, strange/rough/loud running, misfires etc...

I cut the converter of to see if it was the problem but it ran the same I am almost certain that its jumped time or at least I hope so thanks guys for the help

I started the jeep up today to try and check timing and it is now smoking like a freight train and for that matter how foes on check the timing on a 4.0 I couldn't find any timing marks on the harmonic balancer?

poorstang

Anyone have any ideas on checking timing

poorstang

No ideas????

sorry. I have never checked the timing on one.

Got a chance to look at the jeep the other day and the head gasket is blown should I go a head and get the head rebuilt while it is off? It has 163000 miles on it couldn't hurt right?

She will be understanding UNTIL the wedding. After that you will need to get that piece of *%&# out of her driveway. Its making the house look bad and the neighbors are complaining.

If you're going to keep the vehicle, I would definitely consider doing this. Usually it isn't too expensive.

poorstang

Yeah im keeping the jeep hopefully forever lol

With 163000 miles personally i would go with a whole rebuilt motor. Putting a rebuilt head on a weak bottom end is asking for more problems.
