The trigger has been pulled!
They are doing the repair with a snap-on system.
I will likely be picking up the engine next weekend. I need to start getting the other items I need to pull this off:
- they are giving me the flex plate
- they will cut the cross over just above the cats in case long tubes don't work out.
- who is the best source for a torque converter and how do I know it will work with my 4r70w?
- best obx long tube source with cats? Wrap the header or leave it exposed. I don't care about the appearance.
- o2 sensor extension source?
- I'm leaning towards denso iridium plugs. I planned to have this tuned for 93 octane towing. Should I run the standard heat range? Source?
I know there is much more, but will tackle it when I get there.

 

I would suggest you make sure they use a timesert kit

 

PCM + wire harness Talk to your scrap yard before they cut it off the engine

 

JMC
Why would I want the pcm? Wouldn't that make things more difficult? I don't have pats on my truck.
Would the pins on a 98 truck and 99 harness be the same?

 

...

 

Scratch the PCM and harness. I, for some reason, thought you had a 4.2. My bad.

 

jbrew,
I won't be getting the converts. They won't sell them. I simply asked for as much of the material upstream of the converter as possible to make welding to what I have easier... I hope. At this point I want to go with OBX LT with there cats, but I don't know if I will have fitment issues.

As for the extensions, I think I would strongly prefer these if the price is reasonable. Heat, fatigue and corrosion are always the enemy of reliability. F'in around with soldering sensitive electronics that operate in a brutal environment just doesn't seem like a good idea to me. I'm all for eliminating potential failure points even if I need to spend a couple $$.

Great info guys! I really appreciate the feedback.

 

thats too much money for that engine and specialy with issues all ready, i bought a 2004 5.4 with 65000 for 1200 last year with the aluminum intake in nj

 

Yea, I don't know what your talking about now. I did spend time giving you the cheap and easy alternative, no soldering involved what so ever... What I suggested is using the part that fits, NOT the ladder. The soldering was posted for you because you planned on "making" extensions of some kind. And if you plan on doing that without soldering, it's sort of crazy IMO. Piecing O2 wires all together in such a way WILL most likely end up being problematic, not right away if your lucky. Right after hitting a bump in the road perhaps. Thing is, it isn't even needed, extensions aren't even needed. A solid harness is really the way to go and come on, O2's are really not that expensive considering their value. Plus all the headaches you can avoid. I hope you really know what your doing down there and have the right tools, - that's your AF's after all.. Yea, I don't understand your thinking and your apparently not understanding mine. That's okay, I'm not going to be of any help this way tho, Sorry.

You have it figured out for the most part.

Good Luck man.

I have read about this. Are there any photos out there on this set-up?

 

Timeserts may be an ok way to fix threads, but I have a lot of miles on my "helicoils" and they work fine. Have you had problems with helicoils before?

My f150 had a plug blow 4 or 5 years ago... maybe around 270,000 miles or so, I don't remember. The helicoil is still doing fine today. (odometer has been broken for about 4 or 5 years on 280K so who knows how many miles)

I have a helicoil in my V10 f350. It was done around 80 or 100K or so... (don't really remember). It now has 170K, and still going good.

 

I've only done it the right way so no I dont have experiance myself with them. Seen lots of guys post on this board about there heilicoil blowing out again though. Sounds like your a lucky guy Chester!

 

Jbrew,

I completely agree with your last post. We're just miscommunicating.
