old oil.

[08 gp lvr]

I had a severely stripped bolt on my oil pan and bcuz of this i went way past my regular oil change interval. I should have gotten at least two or even three in that time, it was black foamy sludge. My question is what can i clean that the old oil may hv gummed up? My idle now is a little off but most of all my gas mileage is bad even with fresh oil. I can still smell old oil when engine is really hot but i have good oil now. I appreciate any feedback

id put nothing in the crank case but oil. and oil only.

tune up time maybe?

Ive ran seafoam in my oil before. Just dont leave it in there long. It should help clean up alittle bit.

I was wondering if cleaning intake and egr if thats possible if that would help. I did my plugs not long ago but didn't do much.

Trans fluid in the oil is the best cleaner.

Run it for 1,000 miles or so and change the filter.

I'd just change the oil and filter a couple times every 1000k or so. I think that's the safest way to flush out an older motor.

This. Done it plenty of times in the past with no ill effects.

What does a stripped bolt in the pan have to do with getting an oil change?? Or was it the drain plug?

My exact same thought


Unless it was the drain plug then it wouldn't be enough a reason to skip over having one done

I think he ment the drain plug. How did it get stripped?

[koRnhead]

That'd still be a stupid excuse to not change your oil....let's see a couple hours and what 100 bucks max to fix that....or 500 plus for eating your bottom end? And swapping a motor.

Yes it was a stripped drain plug. I stripped it using visegrips one day and just kept getting worse over time. I ended up bringing to a garage to get it out, stupid move i know. I removed and cleaned my intake today and it was covered with wet oil seemed like. I've done it before but it was always dry as heck but not this time. It smelt like old oil. It scared me to see that hoping i didn't screw something up

[REDCRAPGP]

Future note.. Never use vicegrips on something like that.. You can easily use a 12 point socket or there's other ways of getting it out before you have to resort to vicegrips.

Stupid move on the vise grip part lol. I cleaned my egr and pcv housing. I ran my finger along the inside of the intake or plenum of the motor and it was covered in blAck wet oil. Sometimes i love that car more than the wife cuz it dont talk back lol. I just cant understand y that would be, I'm just praying that i didn't do permanent harm

The PCV goes into the intake tubing on your year, it's not uncommon to see oil mist on the intake tubing after the MAF sensor.

[koRnhead]

So rounded the nut on your drain plug?? Or actually stripped the threads? I'm just curious here. Cuz a new drain plug is like 5 bucks.....die grind a grove in the old one and big screw driver to get it out.....best advice tho. I'd change your new oil again at 500 or so miles on it. Get that stuff out, it's going to be dirty very fast.

Just out of curiosity, how much transmission fluid would one run in their engine for the aforementioned cleaning method? I can't imagine more than 1 quart along with normal oil...

[Fivefingerdeathpunch]

I always just replace 1 quart of oil with trans fluid. Run it for a few hundred miles and change it. Thats if it's really nasty inside.

If you know the motor is sorta clean already but would just like to keep it extra fresh just do half a quart and run it for the entire length of the oil change.

I always run 5 quarts in these motors anyway, so half a quart of trans fluid won't reduce the mileage you can run on the oil.
