Just found out my 96GT 2V motor is burning oil. It's been smoking like crazy when I accelerate at stop lights and its a very rich smell coming out. It has a 150K on it. I'm sort of on a budget so I was trying to find out which would be cheaper out of the three:

Rebuild
Pi Motor Swap
Pi Swap

Or what should I do?

I'm a noob so go easy.

THanks!!

Assuming this is a street driven DD, IMO the best cheapest is a PI motor swap from a salvage 99+ Mustang
2000+ Crown Vic, Grand Marquis, or Town car.

Try car-part.com for sample $$.

it depends on how much money you got or your willing to spend , but your best option of the three would probably be just a whole pi engine swap. since your burning oil there's probably a problem with the block or piston rings not sealing . so just a pi swap on your current block probably ain't gone help much.

if the block was in good condition though i would do a pi swap cause it adds compression if your staying naturally aspirated and that's a good thing.

but you could rebuild your block if you wanted or get another npi block from the junkyard and put your npi heads back on it and add pi cams and a pi intake.

or you could have a compression and leakdown test done to see what condition the engine is in and too see where the leak is coming from.

there's a lot of options.

Thanks guys. I found a 2001 Grand Marquis motor with low milage. Will this bolt right up or what things would have to be changed to make this fit right?

Consider it almost like a long block. Transfer from the old engine,

oil pan
ignition.
wiring. This is important!
fuel injector and Fuel rail
EGR
Throttle body
exhaust manifold
dip stick
May have minor changes in the PVC valve.
New motor mounts.
If your car is a manual, will need to swap flywheel. New pilot bearing.
will need a heater return line from a 2001 Mustang.
remove the CHT and knock sensors.
Consider a coil pack to COP conversion. Re-use the COP's that will come with the replacement motor. Use this harness:
Plug and Play COP Conversion Harnesses!!!!

Will need to plan for the 2nd temperature sensor. There is a drain plug down on the block that works. Other ppl tap a hole in the intake for the 2nd sensor. Make sure the new motor has the metal coolant crossover.

OBTW, I have done a similar swap of 2004 CV into a 2000 Mustang GT (windsor to romeo).

Yeah I have an automatic.....Will i need a new computer or can I use the one I already have?

If you are re-using the original wiring harness and ignition, does it make sense to change the PCM?

By treating the donor motor "like a longblock", you are re-using, transferring the things that make it "Mustang specific".

Do you think that a PCM from a Grand Marquis would work in a Mustang? :nono:

Got you!! I'm noob so I'm learning lol. I should be able to find a Heater Return line from a salvage? Or is it possible to buy new?

 

[wmburns]

It will be difficult to buy a heater return from a salvage yard. Why? Because salvage yards sell complete motors. The only way they would remove parts from the motor is when the motor is no good.

Most salvage yards will scrap motors not suitible for resale.

Not to say that it can't be done. Just expect it to be more difficult. Try car-part.com

Personally, I would try direct from Ford.

Note, it's possible to re-use the original heater return line. But this will require removal of the water pump valley nipple and swapping from the old motor. It can be done but does require some care to make the swap leak free. If I were doing the swap, I would try to source the correct heater return line.
