Engine Seized
 
Can anyone tell me what the sound of a siezed engine is when you try to start it? I am pretty sure mine is seized, had a massive oil leak, thought I shut it down in time.....Re-filled the oil, when to turn it over and it when clunk.....Any ideas?

Aaron Cake 12-24-02 02:45 PM

Pretty much "click". The starter will not turn a seized engine.

Can you describe what yours sounds like exactly?

myron96 12-24-02 02:50 PM

Yea, when I turn the key over, the starter kicks in, and the engine actually makes a clunk(the best I can describe the noise), and then nothing.....Then to top it off, I started getting some electircial smoke from the rear of the engine compartment, just abnout 5 inches or so behind and to the left of the oil filler cap....Its almost as if it starts to turn over, then just stops...

Aaron Cake 12-24-02 03:10 PM

The smoke was your starter burning trying to turn the engine...It may just be carbon locked though. Do a search to find out more info.

Hey thanks, I was actually looking into that, at a rotary site, they were suggesting turning the thing backward with a pry bar?

Take the starter off, and use a screw driver to slowly spin the flywheel. When you are standing at the front bumper looking at the engine, its rotation is clockwise. So from behind the engine, counter clockwise is forward, and clockwise is backwards. You want to turn the flywheel clockwise as you see it from the back. Take the spark plugs out (label them first so you don't get the wires crossed) and put either ATF (automatic tranny fluid) or MMO in the holes to try to break up the carbon. Rotating the engine backwards will move the apex away from the carbon that is blocking it. It acts like a chock in a tire. It blocks the forward path, but since carbon doesn't build up on the back side of the apex, you should be able to rotate it backwards. Carbon builds up because the engine was designed to inject engine oil into the combustion area to lubricate the apex seals. Burning engine oil leaves carbon. Do some research on how to disable the oil injection system and start using 2 stroke oil in the gas tank. It mixes better and was designed to burn cleanly without leaving carbon deposits.

HEy guys,

Doesnt look to good for the car. WE tried to rotate the flywheel counter clockwise and clockwise with no movement what-so-ever..Any other ideas? Sell it? Scrap it? Burn it? Dump it in the quarry and report it stolen?

er, buy a reman engine, that's whay *I* would do. Not exorbantly (sp?) expensive, and saves your car. Heck, if you have an N/A (had, heehee) and are willing to put more money into it, do a TII swap. Much faster car afterwards.

dr0x 12-25-02 01:29 PM

Ditto on the reman. Or rip this one apart and see if it is possibly to rebuild :)

Aaron Cake 12-25-02 03:58 PM

If it has carbon locked, there will probably be damage to one of the rotor housings. In that case, it's probably best to just get a good used or reman engine. If you want the fast, then install the TII engine (and related support systems).

Project84 12-25-02 06:20 PM

Price out a new/rebuilt engine, then see if it would cost more to rebuild your old one.

Put it in 5th and try to push the car

Put it in 5th and try to push the car
 
That's the best place to start.

Then check the ground wires. If the main ground fails, the others will burn trying to carry the load..

Aaron Cake 12-26-02 09:44 AM

If the engine has carbon locked, and you want to try and rebuild it, DON'T try to turn it over by towing the car. If you take it apart now, it might be salvagable.

myron96 12-26-02 12:01 PM

I think for now, I am just going to keep it in storage, although would be willing to sell it to an intersted party...

HAILERS 12-26-02 12:23 PM

I'll give your five hundred if the shipping is free. humor.

Aaron Cake 12-27-02 01:02 PM

I'll give you 500 if the shipping is free. Serious.

myron96 12-27-02 02:02 PM

Hoping for a little more then 500???
