so I just swapped my plugs out for a new set of ngk ones. car was misfiring a bit when it was cold after letting it warm up frmo driving it would go away. but needless to say i decided i was going to gap them a bit smaller yet so i pulled the plugs out and heres what they look like. The black plug is on the number 2 cylinder and when i first pulled the plugs after buying the car there was some thick malasses like stuff on the plug so i figured i would swap it out. ( it was also very awkward feeling to get out and also the new one didnt feel like it was going in proper). Now at this point im not sure what would be wrong thats why im posting. it almost seems like the threads on the engine for the plug are a getting stripped but im not sure and havent went that in depth into it yet


any help would be awsome thanks guys

 

appears to be the spark plug didnt seal proper and got some blow by, plugs now replaced and sealed good but coil boot is toost so hopefully this fixes the problems

 

looks like that plug is missing its gasket!!

 

Does the car run better now? I would probably leak test that cylinder to double check. Don't forget anti-seize.

 

Plug has it's gasket, it ran better after I clean the coil boot out a bit lots of rubber fragments, deff needs to be replaced, will leak test cylinder but it's starting to look as though that spark plug shaft is gonna need a helicoil

 

Take a close look at the plug. Sometimes the insulator can crack or otherwise not seal allowing blowby to come up through the plug. But, yeah, most likely a thread problem.

 

The plug appears to be good Im pretty sure it's a thread problem the previous owner must have cross threaded a plug in there. The new plug is now sealed well but the boot is toast it's falling apart and cars running like crap, so new boot will be here Wednesday. Also is anyone familiar with having the retapping/helicoil done?

 

Anyone?

 

ok so im currently looking at time sert kits for the car not sure which kit im going to need, but would anyone trust this or do you think i should just replace the head. i cant really afford to get a cnc cylinder head at the moment but will this thread kit work for the time being untill i do buy a new head. i get the feeling the thread insert isnt the best idea as a permanent fix...

 

If done right it should be a permanent fix.

 

Thankyou, I called a local engine shop they've done it many times it's a pretty comman thing to do to ford engines they said, now they quoted me 400 to do one sparkplug I've never dealt with this before so I'm unaware if that's a resonable price specially when I've seen used heads for just another 500

 

Do not put antiseize on your plugs.

 

i wasnt going to lol

 

That price is insane btw. It's pretty damn easy. You can get a helicoil kit and just take your time and follow the instructions. That mallassas stuuf you saw was probly this thread sealer called Indian head. That stuff is awesome I don't no how it would like those temps. But for normal stuff it's way better than Teflon, if they made a condom I'd buy it

 

Ya I kinda figured that was a crazy price, the plug is in and sealed good as of right now so I'm not gonna mess around with it till it needs it, coil boot came in and the car is running fine again. So I'm just gonna leave it till I need the plugs changed
