Low RPM loud knock

Where should I get the parts from? I need them fast! this is my DD. Oh does anyone have a procedure to remove and replace? Can I just replace the tensioners?
Thanks for all the help guys!!
 
IMHO, you be "back on the road" quicker and cheaper if you find a replacement motor and just drop it in.

no telling what you are going to uncover when you pull it apart.

this is sage advice, although I know you wont want to hear it.
PULL the motor, dont try to fix it.

THEN.. once you have your car up and running and back into DD status...THEN.. you can pull the old motor apart, and diagnose what is occuring.

Trying to fix that motor in the car is going to be an expensive AND time consuming endeavor..and if you aren't VERY GOOD at setting up the cam timing.. your gonna create more problems when putting it back together.

I've seen MORE than 1 person FUBAR the cam timing on a mod motor...so dont think I'm picking on your mechanical skills, as I am not.

I'm only trying to save you money, time and headache... since this IS your daily driver.
 
I will try to replace the guides and tensioners to save it first. Im not going to mess with the chain. Im def not Sean Hyland or anything (mod motor king)
 
Good luck.
When you get the cover off snap some photos and tell us what you find went south.

I hate to say it but having a Mark as your only DD is not a good plan.
I have been stranded more then once by my 93.
Sometimes I wonder why I keep the car....untill I fix it.
Then it reminds me :)
 
HOLY CRAP!!!! I fixed it!! The crank pully was coming off! I talked to some mustang guys and they said the torque spec that comes with the March pullys is crap 65 ftlbs. So I re installed it the proper way and its fixed! no more sound!
 
I agree, Mine wants to idle high every now and then, I can get it to idle down by reving it up a bit, well today I left work and had a huge chuck of open road, I floored it, man ran like a camp pasted to the back of the seat did not back off till 110 blew some carbon I guess little rotten egg smell after
 
Well my Mark may be out now - the trans. Very close to just parting it out. Anyone looking for an 04 engine? lol

what did you do with your air injection so the pulley would fit
pics?
 
My first set of under drives, I removed the bracket and bent the piping toward the fan to fit . When I installed the new march pulleys the air injection system was removed completly. It is possible to run a small crank pulley with the air system in place, but you have to be willing to be brave.
 
Yes but it will need a tune to turn it off. Thanks SNIPER! Guys on that forum helped me for free to solve all my problems.
 
Here is the plan with the exhaust....

01 Cobra Mustang manifolds
Custom EGR tube
Catless Down pipes
Magnaflow X pipe in place of the third cat
Full Deletion of the air pump
SCT PRP to shut it off
 
because it's better to have in a street car/daily driver.

there is no performance gain by deleting egr

it helps a great deal in overall "driveability and manners".

cars with EGR can tolerate more spark advance than those that have EGR deleted.

many many reasons to keep the EGR and the only reason to delete it is cosmetic (its ugly on the cobra intakes)
headers often dont have EGR provisions is another reason people often delete it.

but again, there is no performance advantage or benefit to removing it.
