had an engine 1 misfire in my car.. when mechanic came to check he said my sparkplug broke up in pieces and little chuncks of metal went inside engine. do i need to get another engine. car only has 83k on it. he said i would new another one. do u guys recommend another solution.. he told me dat i would need a new head and probaly repleace piston..
i need help please any techs here.

 

do a compression check on all 4 cyl and if they are all even fire it see how it sounds and drives

 

if ur compressionn test comes back if i were me i would rip it all apart but thats juust me i do it for a living im a tech

 

Source a used engine and swap it out. Prolly the cheapest and easy way if its truly F'd.

 

what he said if it is hosed just get another engine post asome picks of your destroyed spark plug

 

so i proablly need a new head

do u think the piston is done to

 

I would think so if the head is damaged. The plug bits were dancing around in teh cylinder. Ill bet the piston is jacked up a bit and the walls are scored in that cylinder.

 

so best bet is a used engine..

 

Best bet is to try and look in there if possible to see, then do a comp test and make a judgement call from there. If it runs and drives ok without making weird noise, drive it. Just keep a salvage motor in mind soon!

 

thanks man. about how much is a comp test

 

free. they rent the tool at autozone and its very simple to do. remove spark plug, insert tester, crank engine. (there's slightly more to it, but thats the basic idea)

 

thanks man

 

Got a picture of the bad plug?
If just the porcelan broke, it may not have done any damage.
Find a shop with small camera scope and have them look in there to see.
Or pull all the plugs, crank the engine by hand until that piston is up all the way and look with a good flashlight.

any mods on the car?

 

mods dont matter at this point

 

Sure, I was asking because i am approaching the same mile mark as OP. Was wondering if I should do something to prevent this situation.

 

lol take good care of your car everytime you wot is like pulling the pin on a grenade when you back out of the throttle is like getting the pin back in and if it pops it pops

 

no mods on car.

 

how do u crank the engine up by hand

 

You can put a big socket on the Crank Pulley bolt and turn it. You cant bump it with the key?

 

wont it try to bump start if you do that? i just used the crank.

 

It wont try to autostart, its just a real PITA to do it that way. You need to just bump the key, do like 3-4 cranks and thats it.

 

what? so dfco can cause engine damage? don't understand what you mean.

 

He's saying when you beat on the car you are tempting fate. Nothing is guaranteed to be safe!

 

The day my diamond pistons blow up from too much WOT I'll be uber pissed. I do on average 4 3rd gear to the limiter pulls a day.
