It sounds like it is recommended that I replace the O2 sensor when I do the repair. Hughes has them for $50, is that what these usually cost?

 

autozone has the o2's cheaper

 

52.99( bosch) in my area.... this is the prices at the box stores..... they do have cheaper one in the 40's but its a cheaper brand

I wouldn't replace the O2 unless the one currently in was defective ,,, Whats the rationale behind the swap ?

 

The burned oil gunks up the sensor(s). A pre-cat sensor thats not at peak capacity could contribute or lead to future issues.

The post-cat sensor I wouldn't touch unless it generates a CEL.

 

Makes sense, I'll keep that in mind if I ever go down Plenum Blvd.

 

I did some price checking and hughes price is pretty close to what I would pay locally. Thanks for answering my question and then some of the questions I was thinking but didn't ask. Hoping to get everything I need ordered or bought so I can do the overhaul first of April.

I did a tune up (plugs, cap, rotor, wires) about 30K-40k ago, is this something that I really should do again this soon. I figured I would do the plugs cause they are coated with oil pretty good but am unsure how often it all should be done.

Am I biting off too much thinking I can do the intake, timing chain, water pump in three days?

 

you might want to check advance auto parts they have ntk universal for $25 all you have to do is splice it into the wiring of your old o2 sensor thats what i did for my truck and it work fine and it comes with a life time warranty

 

yea do the cap/rotor again, it will be so easy with the manifold out, and for 25 bucks why not....Plenum is a pretty easy job BTW, dont get overwhelmed by it.

 

I am actually more worried about the timing chain than the plenum. Just don't want to run out of time and be stuck without the truck.
