rusty spark plugs?
 
anyone know what would cause spark plugs to rust? i just pulled mine out and they were wet with gas and rusty....and i have not drivin the car. i just bought it a few days ago with a maybe dead motor. any ideas? tomarrow morning im compression testin it. thanx for any help.

We need more details. Has the engine/car sat for a while? does it run now? Stuff like that. Rust is caused by oxidation....a material can oxadize in any enviroment for a number of reasons. It's the least of your worries.

GET NEW SPARK PLUGS
Over the next several weeks, check the spark plugs at least once a week.
If it's gets rusty, it's bad news.
If they don't get rust, breathe a sigh of relief.

I'm with Ted, if new sparkplugs start to rust then you could be in trouble. Rust is usually caused by moisture and if the plugs are rusting then there's moisture in the combustion chamber which is VERY bad.

there is a difference between dirty plugs and rusty plugs right? with my last set, i cleaned them off with a brass brush, and the metal still wasnt shiny like is supposed to be.

If the PLUGS are rusty, I'd worry about the ROTOR. It would rust before the plugs, IMHO (o)_(o)

They will also rust if your plug wires/boots are in bad condition and your motor got wet on that side, if it runs without smoke and smell of antifreeze then you should be okay, just get a new set of plugs and wires, usally aways a good idea when buying a used Rex

joe3180 10-25-04 03:36 PM

well i changed the plug but i dont think that will do any good cuz i just finished the compression test....0 and 30. so im guessin dead motor. oh well. i was going to put a new one in anyway. this just kinda shows i gotta now. oh and the car was sittin around for over 5 months. so now is the question...rebuild or new motor all together?

rs_1101 10-25-04 04:49 PM

you did do the test the right way right? remove check valve and whatnot?
i take it the car wont start either?

I'd go rebuild, but i'm an adventures person :D

car wont start worth a damn but i know its gettin fuel....i can smell that one. not sure bout the spark but i did put new plugs. and the compression test shows nothing so im guessin that it. well i didnt remove the valve but i did leave the push button pushed in. you think that would be the reason? i followed the instrutions on the website.... www.rotaryresurrection.com

water

joe3180 10-25-04 09:08 PM

oh i mean....do you think cuz i didnt rip out the internals of the compression tester it didnt come out right? cuz i held on to the pressure release valve so i could see it bounce and all.

Tofuball 10-25-04 09:10 PM

Dude, if there is rust inside the motor, I SERIOUSLY doubt you can rebiuld it.

The internals are probably trashed.

amishboy 10-25-04 09:33 PM

New motor the rotor with 0 compression is bad. Check the junk yards and there may still be some good parts in the one with 30 take it apart and sell it .

joe3180 10-26-04 01:25 AM

u think someone would take the motor as a core? but yea i think ill part it out. i mean i kinda wanna see what it looks like inside after what i saw. lol. if i do take it apart ill be sure to post the pictures....im sure they will be worth a laugh or two.

RotaryResurrection 10-26-04 01:38 AM

Your internals probably look like this:

Tofuball 10-26-04 08:32 AM

Parastie 10-26-04 08:39 AM
