First of all, Hi everyone im new here

Secondly,

I was given a tired 1.8 escort si
Let me start by saying the car is thought to have done almost 300,000 miles!
I pulled the plugs to replace them.. when I pulled the ht lead from cyl 1 i noticed it was full of oil, as was cyl 2 & cyl 4 ... cyl 3 was dry

Im hoping this is all to do with the rocker cover gasket.. but as you will see the actual parts that go into the engine are a bit shocking too! also, all those deposits on the thread!!!! (perhaps the plugs look so bad cause the oil dripped down as i was removing them)

1st plug as i removed it (the worst)

I heart high milage fords

 

well first it looks like those plugs have been in the car from day 1 lol deffo been in there a long time,if it runs and drives sweet enough i wouldn,t worry high milage like that your going to see this sort of thing

 

yeah it runs and drives decent enough, it has the crap idle problems that zetecs are famed for but i have narrowed it down to a duff maf!

 

probably down to worn rings, a comp will probably tell you the same thing

at the end of the day, if it still runs alright then dont worry about it; i personally woulndnt of even bothered changing the plugs

 

do zetec's not have rubber O rings on the underside of the rocker cover round the spark plug holes to stop this ?. forgot to put mine in when i changed the rocker covers on mine, and i got a bit of oil on the plugs till i fitted the O rings.

 

rocker cover gasket look at your socket

 

Thats probably just from the oil in the plug well that has soaked the plug when you pulled it out. Stick a new rocker cover gasket on and a new set of plugs and it'll be fine!

 

None of those plugs have been burning any appreciable amount of oil, they would be very covered in deposits if they had, just sort the r/c gasket.
tabetha

 

sounds like worn piston rings engines are cheap enough at scrapyards 4 you it done good for milage but if it goes ok drive it til it dies.
