Chapter 2 - The Intake

the only thing remotely close to something like that happening that ive seen was when i did the head gasket on a 96 Geo Tracker and the timing was off ( by the book) and it was backfiring through the throttle body, i guess that could be mistaken for exhaust..-shrug- good thing it was a non interference motor :) just had to roll the cam till the valves were in the proper place and set the belt, fired right up
 
ok when i take my motor apart, this will be my first actual motor rebuild, so, whats the diff between our cranks and a crank from an actual Cobra? i thought our motors were exactly the same -confused- i dont know alot about the Marks other than what ive taken apart and figured out myself
 
the crank differences are the materials it's made from, stock crank isn't forged, cobra crank IS forged.

As much as I hate to discourage a budding engine builder.
I would not make a "mod motor" my first attempt at taking one apart.
well the "taking it apart" part might not be so bad.
But "re assembly" can kick your butt in several areas.

I'd get a small block 5.0..and get some practice first.
if you can take apart a five liter and get it back together and running..that'll give you a good foundation to start on.

the 4.6 dohc is ALOT more confusing and has alot more areas to make a costly mistake, such as cam timing.
 
...or a 4.6 SOHC engine...Ford Crown Vic or Merc Gran Marquis engine......

that would decrease the cam difficulty by about 50% but still has the bank to bank possible variance that causes problem
an sohc 4.6 would probably be "better practice" than a 5.0 that I suggested....as it IS literally the same motor with 2 less cams..all the minor details will be very close.

great suggestion bud

...and prob cheaper!!!
 
and alot less emotionally painful when half the valves hit half the pistons...atleast it wont be his mark 8 motor that self destructs before his eyes.
 
I dunno man I'm putting up the flag on this one

Admit it...you just wanted to use that smiley.
 
Well if I manage to get this thing to run backwards,
people are buying ME drinks at Carlisle... :D

:D -J
 
After reading this thread... hell, I'm going to buy you drinks at Carlisle anyway! Very entertaining.

Offer accepted :D

I thought I was going to have time today to button it all back together, but it looks like it will have to wait until the end of the weekend...

Ironically, I had an offer on the car today...
So I guess I should fix it sooner rather then later :D

:D -J
 
well i found a car sittin in a field, im gonna try to pick it up after i get the vin run to find out who owns it, its a green with tan interior, after i get done messin with it, ill probably place it here for parts grabs, i will more than likely claim the motor and transmission, but body panels and interior will be given away
so that will be my practiuce motor :) if i can get the car

The Cobra crank also uses 8 bolts to mount the flywheel, the mark uses 6. You would need to interchange the flexplate/flywheel. The Expedition uses an 8 bolt flexplate but I don't know if the ring gear count is the same, also the torque converter bolt pattern may or may not be the same.

Lonnie at BOC can get you the correct plate...
 
So for any and all who might care... :D I did manage to put the car back together... :D

I was sick all of last week, so hanging out in my cold garage wasn't too high on the list of things to do, but by the end of last weekend I was feeling up to fixing it...

Here is the crossover tube after a lot of grinding the paint and rust, mostly rust, off of it...

Here is everything back together :D

A close up of the crossover tube which I painted flat black, I think it looks better in person then in the pictures.



A few thoughts in closing... :D

1. I should have numbered the bolts on the lower intake when taking them off, since there are 3 or 4 different sizes, and after a week I couldn't remember which went where.

2. I'm not sure how big a PITA taking the hood off is, but EVERYTHING would have been easier without the hood in the way.

3. The seafoam might have not been a good idea in retrospect. I could be wrong, this is just a guess but everything that I assume would have been dry carbon had turned into a kinda tar like goo...


Anyway, the car is stupid fast now... it's been so much fun to drive.

Thanks to everyone who helped me out on this one!!! :D :D :D
