Default I smell.... Burning oil?

Ok, after an hour trying to get my headlight bulbs replaced (10 screws, removed grille and airbox later) I got them replaced, Fired the focus up, and I notice a burnt oil smell (it smells like the exhaust of a 2 cycle gokart) (I Haven't been under the hood with it running enough to notice).. I notice a film covering a good chunk of valve cover too. been like that for a long time)

2nd problem: I'm drinking anti freeze. In the 500 miles I've driven since my last oil change, my reserve tank for coolant has been dropping like a rock (I'm down about half a gallon (half the recovery bottle)

Blown head gasket, ish?

Also.

WHY does ford make it so flipping hard to replace simple stuff? My passenger headlight was easy because the brackets for it were all broken, but because of that it aims for my bumper no matter where I place it.

Also, when I pulled the oil fill cap when it was running, my RPM's dropped about 3-400 RPM and idled much smoother. What gives?

It's going in sometime next week to get the TSB's taken care of, and probably investigate the burnt oil smell.

Can you do a compression test on it? If so, do one. If you have a leaking head gasket, you'll be able to tell. Also, check the recovery tank for cracks, it's possible you only have a leaky valve cover gasket and a cracked recovery tank. MUCH easier to fix than a head gasket, trust me on that one. I would also suggest you start it back up and, when you verify the twostroke smell under the hood, go to the exhaust and place your hand in the exhaust. Then, sniff your hand. If you smell the oil there, we have some serious internal issues, if not you likely just have a valve cover leaking onto a hot manifold. Lastly, pull the oil cap off and look inside the part exposed to the engine. Milk in there? If so, clean it off and check it again in 500 miles. If the milk is back.....


If it is a blown head gasket, it will make it's presence known over time. You'll start to slowly lose power, and your MPG will drop. V6 MPG, 3cyl power. V8 MPG, 2cyl power. It won't pass emissions anymore, either, as the ECU will likely be fattening up the mixture to get it to quit knocking/sputtering, it may be idling high. If the ECU doesn't do that, it will be idling really rough. After a few hundred miles of that, it will start dropping cylinders altogether. This is when you shut it off until it's either fixed or replaced, because if you keep driving at this stage, you could fill a cylinder with coolant and destroy the entire engine.

All the while it's going to be chugging every fluid it can. My engine was on a gallon/month coolant habit, quart/month oil habit and 5MPG fuel habit right before it started dropping cylinders. Revving the engine will only speed things along, and may even elicit a catastrophic sudden failure of the gasket. You may also notice a lowering redline, as there won't be enough compression and power left to rev all the way up in gear. In neutral/clutch down it won't really change(Tho it will be rough). Mine was as low as 3100RPM before the gasket completely failed.

I've been down this road with my F150, Cluff. They usually have about 3 months to live when they start manifesting the symptoms you have, barring something causing a catastrophic failure beforehand.

PCV valve

also your coolant issue could be a leak or a defective radiator/res cap

PCV valve after 15K? I heard you have to remove the intake manifold (or have small hands) to get it replaced.)

15MPG?

Look under the oil filler cap and tell us if you see milk underneath it...

pretty sad that a 2.0L thats rated for 27mpg (with my normal focus foot) gets the same mpg right now as a 2.4L turbo gas guzzler with a lead foot)

Going to go look, back in a minute (if I can find a flashlight)

Ok, even warm I'm short half a gallon of coolant (It even warm the level is at cold full) There is nothing milky on my oil cap, but I can see milky on my camshaft. I have a video of it idling while cold, and when it fully warms up. (sorry for the shaky video it was more for audio than sound.)

Warm:


Engine cool: I also took the oil filler off so you can hear the drop in RPMs' and hear it smooth out.


Stained valve cover

looks to me that someone spilled oil doing a change. I would suspect you have a small coolant leak what makes you jump to a major repair like a head gasket did you overheat it bad?
