[QUOTE=AdamL187;3305175]at this point it is not the cat, i can smell unburnt gas from the exhaust so one of the pistons arent firing. im going to check the spark plugs, if there is nothing wrong then i will do a compression test. its cold as **** right now so im gonna wait a couple hours.

im taking out the spark plugs now, the three that i got out are black and smell fuel soaked. the furthest one to the right is tight coming out. i am putting a lot of force trying to get it out but i dont want to break it. it did rotate a few times before getting tough. help me out. what should i do next.

 

Yes. Yes I have. I've seen a piston blow a piece off that then shredded the sleeve and destroyed the exhaust valve. It can happen, it's just not that common.

A lot of people can tell because there's on average at least one thread every other week asking if their engine's blown. Generally if it sounds like total ****, something inside broke.

Although, now that I watched that video, that's definitely not a cat, something is really fucked up with that engine. Make sure every cyl is getting spark, and if it is then time to tear it apart. Check for oil on the pistons/plugs too. I would recommend not starting it again until you got a compression and leakdown test done.

 

[QUOTE=Nussle;3305182]turn it back in and try backing it out again. it may have just cross threaded a little

 

Same here, not one problem yet with them.

 

what a bitch, i have to turn it back an forth then wait ten minutes while wd40 soaks and turn it back and forth some more. but it is slowly coming out.

 

Bet he finds the end of the plug has some aluminum welded to it.....

 

should i go with the iriduims or coppers? and i one some website it said to use needle nose plyers to gap them, not a gaping tool because it will take off the iriduim coating.... so how would you measure the gap.

 

Im thinking a helicoil will be needed,because it is slowly taking the threads out with it.
Unless you have some luck on your side.

 

you were right my friend, the end is blown off too. and the threads are trashed. im uploading pics and ill post them. what do i need to do now?

 

It would be great if you could blame the end of the plug doing the damage.

Take a good macro pick of the end of the plug.

No warranty left i guess

 

bump

 

HOLY ****.... Uhm, hope for your sake that **** didn't go down in the motor.

NGK BKR7E copper plugs gap them .32-.35 and try again.... and hand tight the plugs down and then do a quick 1/4 turn further!

And pray that missing metal isn't in the cylinder!

 

im pretty sure the threads are stripped so bad from the end of the plug that a new one wont go in... and i can see marks on the piston where it hit the spark plug.

 

HOW did this happen again???? Was the plug longer then the other's???

 

i have no clue how it happend, its just what i found once i got the plug out. guess i have to take it somewhere because i dont know what to do next. i guess no one else has had this happen.

 

That's crazy i have never seen anything like that. Is it possible that one of the plugs was different than the other 3 ?? If i were you id pull the others and compare them to the Mangled plug the best you can. ANYTIME i install new plugs i always compare the one i just pulled to the one i am about to install..Ya never know.... Did u get them at autozone ????

 

That plug look EXTREMLY long for being in a 4cyc IMO

 

owned. that wierd and i thought i had it bad when you can put ur finger threw my #2 piston

your gonna have to take it apart, hopefully the stealership can take care of it, im thinkin teardown

 

def a blown engine huh guys??? Now you see why i wouldnt say that was the problem?

 

I will tell you how it happened.

He changed the spark plugs, then the engine broke.

There is no rocket science here.

Why did you change the plugs the first place? Did you use the right kind? You cross threaded it installing it, you damaged the piston. You used WD40 on a spark plug (which destroyed engine oil). Your engine is probably damaged significantly at this point, I would get some additional help before trying to put it back together again.

 

ouchy

 

i used the right plugs buddy, i compared the two when i changed them, i changed them because the car was running like crap. it kept running like crap and one day the check engine light started blinking but would only do it in higher gears. my guess is the misfiring blew the end of it off. what caused the misfiring is beyond me and it will have to be opened up to actually tell what happend. many things could have caused this. i did not cross thread the plugs, i tightened it with my fingered then torqued it once it was already threaded through. there was melted aluminum at the end of the plug where it got blown off, thats what caused it to strip out. i love ******** that act like they know all.

oh and if you really think that i care about the oil at this point your crazy. besides i barely sprayed it and the most that would do is make it smoke for a second when it first started.

 

"Nussle" i love ******** that act like they know all.


^^^o wow

Halfcent..... knows more than you I can image but I read that you wrote

 

lol well hes wrong this time. he can just come out and state that i crossthreaded the plug? thats not even why it stripped out. i stated earlier about the melted aluminum at the end of the plug.

i really think its impossible to say anything about your car problems on here without getting bashed. there is also oil on the plugs. the car has 60k on it now so im not real suprised that this happend.

 

Oil on plugs usually means piston ring failure (which people refer to as a blown engine). Do you ever get tired of being condescending and wrong, Adam?

Let this be a lesson to you Nussle - if your car has a blinking CEL then you need to do a compression and leakdown test IMMEDIATELY, then if both of those pass try replacing other parts.
