Question about Ford Escape
I have a misfire from a spark plug due to oil leaking into it. this also has a burnt oil smell after driving for a while. is there a crack somewhere? I already replaced the spark plug several times.
Have a compression test done on the cylinders...sounds like the rings are bad allowing oil to blow into the cylinder...you may be able to fix it by adding a can of seafoam to your oil and see if that fixes it within a couple of weeks. You can buy that at any auto parts store or walmart or kmart.

Hi, Yes it certainly could be especially if water gets in. You should also check the distributor cap. The misfire sounds like an arcing problem so it would have to be one of those two things since you changed the rest. Good Luck!

I would start by doing an oil change myself so you can examine the oil and look for water/antifreeze in it. You will be able to see it separate from the oil and you can smell the antifreeze. If there is then you have a leak between the water jacket and the heads somewhere. More than likely the LOWER intake gasket is leaking into the head. You said they replaced a gasket but was it the UPPER or LOWER? If it was the LOWER did they use RTV in the correct areas? Did they torque the intake bolts to the correct pressure and install the bolts correctly? I know you don't have these answers but these could all be part of the problem. It may be leaking more at #2 cylinder and causing it to foul more than the others. Also just because a mech pressurized the coolant system and didnt see any change in pressure (hopefully he wasn't just looking for visible leaks) the issue may not happen until the engine is hot, as metals behave differently when heated, especially aluminum which the LOWER intake is made. Have a mechanic or mechanically inclined friend (gearhead) remove the #2 plug wire, then kick the engine a few times without starting it, enough to let any fluid get into the chamber, this would include gas btw. Then remove the plug and look for any wet residue on the plug, gas will evap. quickly, antifreeze/oil won't. again try to smell the residue and if necessary, lightly touch some to your tongue, antifreeze has a sugary sweet taste that is easily detectable. Remember any time you are working with chemicals such as waste oil and especially anti freeze, minimize spills and clean them up quickly and completely and place the spent fluid in a sealable container and take them to a collection center for disposal. Waste oil is a carcinagin (cancer causing) agent and antifreeze (glycol) new or old will kill any animal (child, dog, cat,etc) that ingests it. Many auto parts stores and some other retailers that sell oil and antifreeze will take your wastes if you bought the replacement fluid from them, check before you buy.

the fuel injector is not pulsing correctly,it probably has something in the screen in side of it,you will need to check that screen in the injector or replace it
