Will this diesel run on biodiesel.

Ira, Depending on your vehicle, some modifications may have to be made, it use to be all diesel engines could, now with the new injection systems they say you have to be careful of contaminating engine oil, and emission problems. It seems in newer diesels, the Bio fuel does not vaporize as well and contaminates oil. Check the attached links,instruction and guides, last link may list your engines compatibility. Good luck

Oil leak

Check your oil pan, did you run over something? That many quarts of oil has to be leaking from somewhere. Headgasket blown would likely show as water mixing with engine oil(no loss of water would likely remove likelihood of blown headgasket).

Running rough and white thick smoke from exhaust

sounds like you are burning coolant. sounds like you have a headgasket issue or cracked block. is your coolant level low?? in the overflow bottle and in the raadiator? something tells me that you will find that coolant is low. you are pulling coolant into the engine and it goes into the cylinder and pass the exhaust to the back of the car. the white smoke is the coolant burning off and thats why the car runs rough, because coolant is not flamable so it doesnt burn. this results in the spark plug not firing right and having rough running condition.

My sidekick will just die or barely run it died

last year, OBD1 car (dumbb ECU)
no scan tools for it
if you run on the road with that hack , and wreck
expect a nice fire. fuel fire.
if you used a voltmeter and say 12vdc there, all hotwiring stuff
need not be done. (
it stalled (misfire)
and then would not what? start but cranks ok?
3sp ,4sp auto or 5speed stick
16v engine or 8v, both are G16s but EFI radially different.
16v is MPI with 4 injectors, 8v is 1 injector TBI
try a new
cap,.rotor spark wires and spark plugs yet?
cant burn fuel with bad spark
i guess the cam bent did not slip as it run ok later, but is 60,000 mile belt. and will slip ignored.

next time it stalls
check headlamps they work, and all electric
then see if CEL glows key on, i must or ECU lost power
it has 3 fuse that can rust, IG coil, FI, and DOME.
the CEL must glow, is first checks.

Put bio in tank instead of the city diesel wont start now which fillters will i have to change

Was this homemade biodiesel or something you bought from a gas station?

If it's the homemade stuff you are living in a cold climate you may just want to put some petroleum diesel in and put the car in a heated garage for a day or two. Be sure you have a safe place to warm it up. No point in burning the garage down right?!

After a couple days heat soak inside you might be able to cycle the key on and off to pump the fuel around to loosen up anything that may have congealed in the fuel lines.

Two days inside a properly heated garage and some petroleum diesel is the safest and cheapest way to rule out gummy fuel. Plus, it this works you can just run the bio diesel off and refill with petroleum diesel. Bonus!

Can i use biodiesel in a 1.4 tdci ford fusion

when mr deisel invented the engine he used peanut oil (diesel fuel wasnt invented)you can use biodiesel in any diesel engine although the makers(ford etc)will tell you NO(they dont want any warranty problems).
the only downside is biodiesel will clean lines/tank and any free floating bits will clog filters.some fuel lines will need to be changed {LOOK UNDER BIODIESEL IN HAWAII) marine engines in the islands use only biodiesel as it is NOT poisonous to marine life.

I put another engine in my 1988 ford 250 deisel and smokes a lot, I've changed The injection pump and reset the timing, Plenty of fuel and runs great but smokes unbelievably, What could I do to get it to...

Before you do the next oil change,get a can of motor flush.
This is the inexpensive method the free up the rings and restore some of the compression.
Use Shell 15W40 oil ==
Do you know the history of your replacement engine?
When was the last timing belt change?
A loose timing chain and guide can cause injector timing problem.
==== Start monitoring the coolant level for protential head gasket leak. ====
To save time,I would do a high rpm (below REDLINE) highway ran to blow off all remaining diesel SOOT.
Let the shop to do a compression test. DO NOT DO THIS YOURSELF.
The max psi is 1850 PSI
=== Stay away from biodiesel blend fuel until you figure out what's the cause of the problem.
Use Diesel Cleen silver bottle and see is there any improvement. ===
Add the recommend dose of SEAFOAM into the crankcase to soften the valve stem seal.
Leaky valve stem seal can introduce oil drop into the cyclinders over-night. =====
Mointor any oil lose from valve cover.

Is the smoke only from tail pipe?

Please post answers and I will follow up on it.
