So, when I did the ball joints I guess I didn't press the boots on enough. After I got it all back together the passenger side lower ball joint pulled up and is now offering minimal coverage of the ball joint.

Any tricks to pushing the boot back all the way on without taking everything apart again?

I was poking around  the engine compartment and checked the voltage at the oxygen sensor and it was reading .9 volts.


I read another thread on the forum and it says it should read .3 or.4 volts.


Mine is an AHB with the thermoquad and still has the lean burn. Should it still read .3 or .4 volts?


I set the A/F ratio a while back by using a vacuum gauge with the highest vacuum, that somehow got me up to .9 volts with the O2 sensor.

Wouldn't the voltage reading at the O2 sensor be completely dependent on what the O2 sensor was reading (the exhaust fumes) at any given time?

I'm probably wrong...no idea.

Pretty much, but you can still get an idea of whats going on and if the sensor is bad by how far off the number is then it should be. I've never used one of tuning. Especially now oriignal sensors aren't going to be overly accurate.

I had the engine idling and it read .99 volts. I turned the idle mixture screws and the voltage reduced to alternating with .2 to .7 consistently.

I figured that with the lean burn and electronic feedback carburetor it would prefer more lean that rich, give the o2 solenoid a chance to adjust as needed.

Jusr curious any one else have an issue with their AHB where oil leaks out of the top of the oil filler tube while the vehicle is running?


Oil pressure sits between 60 and 75 psi at highway speeds just over 2000 rpm.

That is NOT GOOD.  That is caused by blow-by, or where the ring seal on the pistons is compromised.  What shape is the PCV in?

I assume the PCV is good. It still rattles and does not look damaged.


I could replace the PCV to be on the safe side.


I always figured blow by also blew oil into the air cleaner? which i dont see.

Wait, I misread the post.  You have one of those filler necks on the valve cover?  For some reason in my head I read dipstick tube.

Is there a baffle in valve cover under the filler tube?

I can't speak to factory valve covers, but my aluminum Mopar ones would leak horribly without the baffles in it.  I don't know how you would go about putting a baffle in a factory cover though.

If it needs a baffle at the filler something is still odd because it still shouldn't be doing that.
Try seeing also if the PCV hose is blocked or the port it goes to.
That's a lot of pressure or something strange to be causeing oil to come out there.

That problem was narrowed down to the torque converter problem...lots of vibration throwing oil.

So i have managed to break 3 manifold vacuum trees from the manifold ( supplies vacuum to accesories) from 3 different vehicles.


Im clearly doing something wrong


Now i am need of a new vacuum tree, anybody have one or know of one that i can get that fits the 318 4bbl intake?

Stop messing around with the factory plastic tees.  Look for one of these:
