Well, obviously it's the first two, up near the exhaust manifolds. Just on a whim, I tried to run it with the center cat removed from the rest of the pipe forward, and with the EGR valve reconnected after I cleaned it up a little. (pulled the mid pipe about 1" back from the ) Car ran (or didn't run) just as before.

Is there a relatively easy way to yank those cats? I only have one jack stand, no ramps, and nothing more solid than packed dirt and rock (with the occasional large piece of wood or stepping stone as a base for the jack) to work with here. My place was never very good for working underneath cars. (only thing I have to lay on is a sample of blue carpet that the last owner of the V6 'Bird used as a floormat)

I may have to call in a friend for help on this one. I also get a little bit paranoid any time I work under a car. It was OK tonight, working on bolts that were pretty easily accessible.. but get me under there for anything involved, and I'm going to be staring at that jack stand every 10 seconds.

Oh yeah.. even with the cats dealt with, I still won't be driving it around.. no tag yet. :p

Well first off, you need to invest in a little basic equipment. Places like Northern and Harbor Freight have decent jack stands and the like dirt cheap.. Or maybe a puppies shop may have something.

The cat problem is also why it was blowing oil. The exaust has no where to go, so its blown by the rings into the crankcase. Probably why the valve covers are(were?)leaking.

I've been trying to assemble a set of basic equipment while I go. I didn't even have a set of crescent/box-end wrenches (SAE or metric) before about a month ago. I just have to make do with what I have until I can pick up more tools and what not.

Right now, any money I make (now that the 2nd car is here) has to be saved up for my fiance's trip by train to Chicago to visit family for Thanksgiving. (already has the tickets) Once she's on her way, I can go back to building up my supplies. I should have a bit more reliable income after the first of the year, (long story) and then I can really get to work on my plans. Somewhere along the line, in addition to the tools and parts and all that, I'm hoping I can try to get some sort of solid working surface put in. Not sure if the concrete shortage is still a problem.. but if it isn't, then maybe a somewhat-larger-than-car-sized slab is in my future next year. I'd feel a lot better about using things like jack stands with that in place.

Decided to make my first attempt at reading EEC codes today, using the jumper wire/dash light method. I got the following:

53 53 (long pause) 1 (long pause) 53 87 53 87 (nothing for more than 10 seconds)

  CODE: 53 (KOEO) - TP circuit above maximum voltage
Engine: 5.0L
Year: 86-93
Description:
Throttle Position sensor circuit above maximum voltage

   

CODE: 53 (Continuous) - TP circuit above maximum voltage
Engine: 5.0L
Year: 86-93
Description:
Throttle Position sensor circuit above maximum voltage

  CODE: 87 (KOEO) - Fuel pump primary circuit failure
Engine: 5.0L
Year: 86-93
Description:
Fuel pump primary circuit failure

   

CODE: 87 (Continuous) - Fuel pump primary circuit failure
Engine: 5.0L
Year: 86-93
Description:
Fuel pump primary circuit failure


Fuel pump primary circuit failure? I just had it running long enough to warm up, and even a brief time over 3000 RPM.

EDIT: I tracked down the breaker in the trunk and pushed it.. (I did hear it click to reset) but haven't re-run the codes to see if that changed. Just ran the car for a couple minutes.. seemed to be a little more difficult to keep it going at first, but it eventually smoothed out and idled fast. (had the EGR pulled again)

OK, eliminated code 87 from the picture. I ran the KOEO once and got the 87s again, cleared the memory, and just got:

53 53 (long pause) 1 (long pause) 53 53 (nothing)

So a TPS is $29.99 at AutoHole.. should I be picking up a new one, or is that TPS-voltage-too-high thing caused elsewhere in the system? (doesn't seem likely, but never hurts to ask, right?)

Also, still won't run with the EGR valve bolted on. I'll have to deal with the whole exhaust thing soon. (took a few days off due to the sleep problem thing)

One more thing: I had my instrument cluster out to check all the bulbs, and now that it's back in, oil pressure reads as the two bottom bars and the two top bars. Bad connection in the plugs? (everything else seems to function properly)

OK, so a friend is loaning me good jack stands and a decent breaker bar to finally get that exhaust off of there.

Decided to clean out the IAB today while I was looking for something to do. Glad I did.. that whole area (inside) was covered in oil.

Ran it with the oil filler cap off for awhile, just to see what would happen. (spitting oil out of there, etc.) Actually ran better, I think.. but quite a bit of smoke was coming out of there. Not exactly pouring out of there, but it was definitely noticeable. Another symptom of bad rings, or just normal? (never ran anything with the oil filler cap off before)

It runs really rough at first, for a minute or two after starting it.. then it abruptly smooths out.

could be a sighn of stopped up converters

Most high milage engines have some blow by due to worn rings. Usually the PCV system pulls the vapors back into the engine where they are burned. You likely have a plugged up PCV system, or really bad rings.

Got a couple safety pins and took a KOEO reading of the TPS voltage.. it's reading 5.01v.

CODE: 53 (KOEO) - TP circuit above maximum voltage


(DH3) Service code 53: Attempt to generate service code 63
- Key off, wait 10 seconds.
- Disconnect TP sensor harness at throttle body.
- Rerun KOEO self-test.
- Is code 63 present?  (Ignore all other codes at this time)
-- Yes - go to DH4
-- No - go to DH5

(DH4) Check voltage Vref to Signal Return
- Key off, wait 10 seconds.
- Disconnect TP sensor harness at throttle body.
- DVOM on 20-volt scale.
- Key on, engine off.
- Measure voltage between VREF and SIGNAL RETURN at the connector (should be orange/white and black/white).
- Is voltage between 4.0 and 6.0 volt?
-- Yes - Replace TP sensor. Rerun quick test.
-- No - Go to pinpoint test C1

(DH5) Check TP signal for short to ground
- Key off, wait 10 seconds.
- Disconnect TP sensor harness at throttle body.
- DVOM on 20,000 ohm scale.
- Disconnect processor.
- Install breakout box, leave processor disconnected.
- Measure resistance between pin 47 and pins 26 and 57 at the breakout box.
- Are both resistances greater than 10,000 ohms?
-- Yes - Remove breakout box. Replace processor. ($$$) Reconnect TP sensor. Rerun Quick Test.
-- No - Service short circuit. Remove breakout box. Reconnect TP sensor and processor. Rerun Quick Test.
Death awaits you all with nasty, big, pointy teeth.

FUN!

Ah well.. at least I have some money coming in this week, and might be able to spare some cash for a new TPS if needed. ($29.99 at AutoHole)

Wow, whatta mess.

Tonight I decided to have a few beers and pull off the upper intake, so I could paint it.. and then paint the valve covers later this week while I had it off. (Ford blue, just 'cause I like those old colors.. Ford blue and Ford red.. although with a car that's someday going to be green, I didn't want a Ford red engine.. too x-massy)

Took FOREVER to get the EGR plate off, because of all the crud stuck around one bolt. But that isn't what I'm commenting on. All 8 intake runners are black and shiny inside, and look to have quite a layer of oil formed on them. (the EGR plate itself is full of crud) I can see the lower is the same way.

Should I do something about this while I have it all apart, or just leave it until I can manage the swap? (undecided now between converting the Windsor to SEFI or using the/a 302)

Got some pics today of the condition of the inside of the intake. Used the lower intake because it was easier to get a light on it.. plus the paint on the outside of the upper intake is still drying. While I was there, I snapped a shot of the inside of the EGR spacer.

as for the oil gauge 2 bars on top 2 on bottom, I believe that means a short. mine did that every so often, I changed the sender, and it did it all the time then. I finally just found the wire that goes to the sender and grounded it, and put in a real gauge
