Jon, thanks a bunch for the info, I'll definitely look into that.

Tony, I just got back from the shop. The news is informative but not good. The #5 Cylinder goes up to 155 and leaks down quickly to 140, the rest go up to 180 and leak slowly to 170. Looks like I'm going to be pulling a head and having it machined and magnaflux.

I'm not pulling the other head as it isn't giving me any trouble and I am of the opinion to let "sleeping dogs lie". If it isn't a good idea to leave the other head alone, let me know now.

Mike--
remember the data "signs" we saw?

the sensor not switching on bank 2 even without the code? That was good data--for future reference. Also the code popping up after the coolant was warmed.
Just bragging up the tool.
BTW--that capacitor didn't get soldered in well, but I have it fixed now.

Looks like the red(pink?) adapter that is in front of the case is missing.

EDIT: By the way, I've got that link bookmarked. If I ever have an extra 60 bucks laying around, I'm picking up one of those scanners!

Not to be pushy, But I was just wondering if you made any progress.

Basically just checking in--
I think I have a line on a 2002 gt air filter box--thanks for the tip--

Haven't had time to do the work. But I got a set of NPI heads sold, so that will help.

I'll start tearing down the engine (intake, front cover, head) this week, order an installation kit, and get the head to a shop ASAP. Won't know for sure till the reworked head is back on

By the way. I called the guy I bought the heads from. He said to keep him appraised of what I find out, and he'd "make it right". So thats looking good to.

Well, got the head taken off today. Its going to the machine shop tomorrow morning for inspection and surfacing. when I got them off, it was very obvious what the problem was. I should have seen it before I installed it, but was just in too big a hurry I guess. Take a look and tell me what you think the problem might be. I sent these pics to the guy I bought them from just a minute ago. I'll let you know what happens. If he does right by me (and I believe he will) I'll recommend him to the club. If he screws me, I'll let you know that to.

Wow!
I'm amazed it even held any compression!!!

I think those took a fall-ride or something straight to the floor.

Well Micheal, you are on the right track now:cool:

Ummm-edit

I don't see how they can take that much off--you'l be at 13:1 compression on that side--

Not to worry. I contacted the seller and he said not to do a lot of expensive machine work, he'd send me another one. I was going to go ahead and at least have it checked out, but I'm kinda leaning toward just getting a new one.

Glad to hear you got it. I hope it works for you. I understand needing cruise very well. I just finished a trip to KC and back in a 5 speed escort without Cruise. Never realized how spoiled I had become with the T-bird!

As I said, I was impressed with this guy from the first time I talked to him. He seemed genuinely more interested in me and my car than in selling the heads to me. And he was open about his business etc. I think that the Phone number he gave me was his home number or his cell number.

Glad you're getting another head rather than milling that one. You don't want to bump the compression that much more on one bank ;)

I can top that news. The seller is sending me another head (as I stated) and he said to just keep the "bad one". So when I have time and funds I'll look into getting the bad one repaired with a weld bead and machining. (so there isn't too much machined off of it) and use as a spare, for parts, or sell it on Ebay.

As soon as I get the new head, I'll post the seller's info. He's been a great guy to deal with so far.

WoooooooHooooooooo!! The head just arrived. I'm going to clean it and give it a thorough inspection, then start putting it on about 2:00 this afternoon. (Thats when my assistant gets off work)

Its dirty (as was the last set) but cleanable, and I don't see any problem upon initial inspection. I'll post up pics when I can.

EDIT:

Here's the new head, as it was delivered. No clean up yet.

Got a question. If you look at the first pic of the head, there is a sending unit in the upper right hand corner of the pic, below the intake ports. Anyone know what this does, what its for? There isn't one on the NPI heads I took off. It looks to be a temp sending unit of some kind.

I figured it was something like that. I imagine it would be a good idea to leave it there just to plug the hole however.

Is there any way we could use it if we wanted?

yes you could use it for the gauge , porkchop used it but the gauge is way off.


Just leave it or remove it makes no difference .

Correctamundo! A lot of guys (myself included) use that spot for their second temp sensor. Instead of drilling and taping their coolant crossover or using a T fitting, they just extend the wires from their wiring harness and use that sensor.

This is what I did using the npi heater tube . My car did not come with climate
ctrl so I cut the tube to lenth and installed the gauge temp sensor there .
