Just check the oil level once a week to make sure it's good until you figure out the misfire. Did you already check for vaccum leaks around the lines/hoses/fittings, intake manifold and plenum?

 

Hahaha awesome!

A leak like that is probably from the front cover area and blowing back but it is hard to know without looking. I bet if you took the fan off and filled it up with oil, then lay underneath with it running for a couple of minutes you will see it coming from somewhere. My rover valve cover gaskets have leaked in the past but the amount of oil was miniscule compared to what you have.

I had... No HAVE... a classic mercedes diesel that I stupidly bought on eBay and then drove 1700 miles without a single check by a anyone who'd ever laid eyes on a diesel engine and it was blowing around 7 quarts an hour through the valve cover gaskets.

Little known fact, there is a 24 hour truckstop or Walmart with Rotella at least every hour from Reno, Nevada to Longview, Texas. You could walk between the two cities and never step off of a Rotella oil slick (at least, after I passed). Also, clouds of oil smoke scare small children at the Whataburger in Albuquerque, and New Mexican parents are VERY protective of their childrens' air.

But I think yours is blowing back. And if it is the front cover just behind the belts then you'll have all of the tools you need in your toolbox and a tube of rtv. Any maybe a new front main seal. Cheap (10 bucks maybe). No biggie.

This has inspired me to bring the rolling turd out of the garage and polish it up.

 

But....if you have an impact drill on-hand, you really should grab a few different extensions and wobblers to take the driveshafts off and at least work the front DC through its range of motion and grease the Ujoints until grease has escaped all 4 caps on the very front Ujoint. No sense in letting that bad boy have the upper-hand. Socket and ratchet, much less a wrench would be a job, but an impact gets it completely removed in 5 minutes flat. Oh, jack one front tire off the ground and you can rotate the shaft. 1 back wheel for the rear DS.

 

I have not yet. I love the idea of the brake clean especially since it has been years since I have been on the local news. Visions of me running with my head of hair completely engulfed.
I did look tonight for arching and did not see any.

 

Facial and head hair, and maybe chest hair... And eyelashes, Well, all hair... is overrated. Gets in the way of mechanic work and is best burned off quickly and cleanly so it doesn't get caught in moving parts.

The first time I did it it was with starter fluid. Now that's dangerous!

The brake cleaner trick does work. Or it did for me. Just be careful. After a few sprays you will be hosing it down with brake cleaner. I would keep it away from the spark plugs and coils, obviously. And turn the air conditioning off for sure, not only so it won't be sucked in the passenger cabin but so the compressor doesn't spark when it clicks on. Oh and keep it away from the alternator.

Haha. What am i saying? I've done this a dozen times! Just be careful.

And follow the directions and obey all warnings on the brake cleaner can! Hahahahahaha

 

Wow, I took NONE of those precautions. Next time I'm dowsing my engine in combustible fluid, I hope I can reflect back on this thread. I was laughing in my head thinkin about Ohio screaming "save me baby Jesus!" Over and over, running in circles bumping into his truck while head on-fire LmAo.

 

Damn Charlie, is that the scenic view from your driveway? Unbelievable. I didn't know you had hills out East

 

No, that was taken on the fateful 1700 mile trip. It did make it back to my little hovel in the piney woods:





And proof that brake cleaner can be sprayed on an engine, .

 

I do have an impact wrench but don't have a vice. Don't I need one to press in the new U Joints?
I think I would be screaming "Help me Oprah Winfrey!"

 

I was more or less talking about a close inspection, just to get you by for a while if all seems OK. and you don't need a vice to replace those little Ujoints. I did it with a large C-clamp. Personally, I had the most difficulty with the C-clips. Getting the Ujoint aligned properly is tedious though. I ruined the bearings in one. I suggest having at least one extra whenever you go to do the job. With so many caps and bearings, the odds are high that you will screw one of them up.
Sorry, I feel like I'm throwing too much at you. Misfires first.
