AOS Question

[Bryan topping]

OK, I got the AOS changed (not all that bad of a job) & cleaned and as much of the oil out as I could.

Questions I have so far are:

1. Should I run a can of Techron through to clean the remaining oil film in the intakes?

2. Would a failing AOS trigger the P0420 & P0430 codes?

3. Would the car sitting on jack stands for a few days on the front only cause this?

The Techron cant hurt and leaving the vehicle propped up in the front for a while shouldnt cause that kind of oil to leak into the intake (unless you had it on a huge angle and running... did you check your pumps?
The 420/430 code usually triggers if the 2 O2 sensors (one in fronto of the cat, one behind the cat) start to read too closely sensing cat failure... BUT... all the oil burning through the system 'could' most definitely cause that....
Get it all cleaned out with the Techron, take it for a good drive (keep an eye on smoke), and then reset the codes, see if they come back... after you drove it for a bit, check the crossover pipe from the AOS to the intake to see if its full of oil again....

I took the car for a 120 mile cruise yesterday & it ran great. No smoke, great power & best of all no codes. Oil level is the same, 1 segment below the full mark on the gauge, almost to the upper mark on the dipstick as when all this started.
