non ford relaited, Run on

my friends car is severly screwed. Ive never seen anything like it. it runs on, it burns oil it leaks everything and its rusty.

but strangely, while the engine is running at idle, on a warm day. you can totaly rip out the HT lead from the coil to the distributor and the bloody thing keeps running! although at only a couple of hundred rpm, indefinitly, not just a few seconds either.

carbon cleaning something this screwed is likley to kill it completly ie destroy what little seal there is left wouldnt it?

its a late 80's camry.


Best wishes

Id say the timing is probably way out.

How does your friend stop the car if it runs-on indefinately?

How can it be timing when there is no ignition?
I think it is dieseling like a champion, but would question the "indefinate" bit. Pull it down and give it a de-coke. You can try the can method, sounds like there is nothing much to lose.

Check the carby is closing and also check the idle solonoid. Does it run on when the key is turned off???? It's running on when you pull the lead off because it will have a carbon build up on the head and pistons causing hot spots. This could be due it burning oil. What does it idle at normally???

Disc the pvc from the inlet and put it in a can [to catch the oil] so no oil can be forced into inlet and motor.Block off the inlet hose to pvc.Check as above retard timming a fraction from specks, this engine is realy stuffed but may get you a few more miles out of it..
Import/ s.h engines are cheap but you said there was rust so its on its last legs.....Believe it or not changing the oil helps too!!

How long has it been since you changed the oil?
You could have a sump full of fuel, one way or another....
Seen this on a 253, which kept running on, caused by the fuel pump diaphragm leaking, filling the sump with fuel and the engine was running on the vapours.

Have a look there. one of the people here are having run-on problems with a 3cyl suzuki swift. There are quite a few knowlegible people here with many suggestions to try before you to a tear down

i third the timing, causes excessive heat, plugs get hot spots and causes running on, happened in my escort all the time when the timing was out. Could be alot of carbon buildup as well by the sound of things
Also make sure hes running the right plugs, If hes running plugs that are too hot it will run on like a mutha f**cka

But no HT between the coil and dizzy means no spark at the spark plug, putting a timing light on pot #1 will result in nothing so it can't be timing.

It can only be dieseling due to hot spots as topGhia said. I suspect if you started it and immediatly ripped the HT wire off, it would stall.
