Until you remove the TB and look inside the intake with a small mirror and light, you will never know. If it is blown, replacing the PCV and using Seafoam will just mask it, and you'll have worse problems in the long run.

 

Alright, So just look for oil pooling up? correct?

 

Yup...

 

10-4, Guess ill be dismantling it today. Ill keep posted.

 

As for the shaking and misfiring; try this...

Lift the truck safely onto some blocks.

Crawl your 440 Road Runner Tree Hugging Azz down under the truck.

Unbolt the Four bolts holding your Exhaust Pipes to your Exhaust Manifolds.

Pull on the exhaust pipes a little bit to create a small gap for gas to travel.

Go for a test drive. Too much back pressure can and will cause shaking at low RPMs.

Until the amount of pressure leaving the Engine is able to easily overcome the potential

blockage in the Exhaust, shaking can occur.

Think about it. If there is a metal chamber filled with fuel and air that ignites, the

explosion will try to escape that chamber through any path present. If the path for the

explosion to escape is a exhaust pipe that sometimes is open and is sometimes closed

then the explosion will travel smoothly when the path is open but when the path is

closed the explosion will backfire and try to escape through any other path possible.

Those paths in an engine's case would be past rings, through intake valves, head

gaskets, etc. If the explosion travels and suddenly stops, that would explain the shake.

To find out for sure if this vibration is coming from a blockage in the exhaust, disconnect

the entire exhaust system and let that engine flow freely by undoing those Four easy

access bolts coming off the exhaust manifolds and pulling on them to create a gap for

exhaust gases to escape. If after test driving you find no more vibration, you need a new

catalytic converter and, in all likelyhood, a new muffler since that broken cat could have

clogged that as well as itself.

Check it out

 

Thanks for this, made my day.

And i will try it.

 

Update: When i was under the truck i noticed something wierd in the front, Where the big black bracket that the tire connects to (on the front) Theres a line of washers connecting the black bracket to the axel type thing, One side doesnt have them. Could that be an issue? I Wish i could describe it better, ill try to snag a picture when i find my camera.

 

That axle type thing, if I'm not mistaken, is pressed into the spindle using many tons of pressure to apply. It shouldn't be any different from the other side. Could very well be part of the problem. Take some pics and post ASAP

 

Nevermind, i double checked it, it's like... a bumper thing, making it not come up to far. but ill take pictures anyways

 

Well i replaced the PCV Valve, and used a small suction tip for my shopvac and sucked some oil out of the intake, No more oil, so i assume the plenums good?
