I wanted to use my air compressor and oil extractor to remove engine oil from the 5.4 that I have. I inserted the suction line into the oil dipstick tube, but I cannot remove any oil. There must be a baffle preventing line from going into the bottom of the pan.

Has anyone else tried this method?
Thanks,

 

No offense but that sounds like more of mess and hassle to do than the correct way. That might work in a differential (still not the right way) but I wouldn't think that would get anything that has settled to the bottom of the oil pan.

 

Kevhead, I have been changing oil in vehicles for many years and I thought this extractor might make it easier. I have only used it a few times on other vehicles and its a remarkably clean way to remove engine oil, trans, diff, and steering pump oils. It may not get all off the debris out of pan but I change oil every 3 to 4k anyway so all of the engines I have rebuilt have been extremely clean on the inside.
Most of the german mfrs are using this method where the oil dipstick tube is run to the bottom of pan so that oil can be extracted by dealers using same vacuum method. My extractor even includes the adapters for the german cars so all you have to do is plug the simple adapter into tube and then you vacuum away. Just saves time not having to remove bottom engine/chassis cover to access drainplug.

 

Sounds interesting but I'm not much help knowing if there are baffles below the dipstick. I am sure someone who has torn one these engines down will know.

 

Somewhere in this forum, someone got that tube 'stuck' down the tube on something and it broke off inside, long story short, had to drop the pan to get the pieces out. The ONLY thing those extractors are good for are small engines and such, I know I use one myself for that. But I would NEVER try to suck out engine oil when it's so easy to change it the proper way.

 

There is a large flat baffle that goes all the way around the pan about 3/4 of the way up the side. The best way to get the oil out is to use the funny six sided object on the bottom.

 

^^^^^ Are you sure that thing has six sides ??

 

haha

That is the thread refered to above. I'm not real sharp with adding links to posts, so if it doesn't work I used "Dipstick tube" as the key word. It's a fun read, enjoy.

 

Leave the extractor to the europeans, they do a lot of strange things over there, this isn't the 1st and won't be the last. Just look at a lot of the cars they build, for proof. Use a Fumoto valve if you think it's too much work.

 

I have not used an extractor on my truck yet, nor will i ever. It is too easy to change the oil in the truck.

but I did use an extractor on my 2006 VW Jetta TDI. Worked great! I actually got all 5 quarts out every time. The only reason I used one was because I couldn't fit underneath the car. And the damn thing had a "skid plate" that went from the front bumper and stretched back behind the first set of doors, and it was as wide as the car. Pain in the *** to get off... Along with everything else on that car....

 

Despite the heckling here, most commercial units are drained this way- using an extractor. From big rigs to forklifts to big CATs. It's certainly nothing new. If yer still down around Devine John, you might want to call over to the Dunsfords shop and ask why it won't work. Been a while since I've been by there so I have no clue who runs the service dept.

 

Poolboy,
That car only holds 4 qts.! You ought to have milked that cow (or was it a sow?) more often, could have put you right in line to make a fortune along with the people who sell you your old used oil back, filtered and mixed with some new oil so they can convince you that it's actually something you would want to put back in your car. Put in 4, get back 5. Heck, at that rate you ought to drive that thing around the clock, that's a whole lot better than having to drill for it! JK

Note my post right above yours- point made!

 

I'm not heckling , just saying that oil changes on these trucks is an easy job. As stated I believe there is a baffle in the pan that makes this job difficult at best with an extractor. I know the commercial boys do this all the time...some have no choice, engines must run 24/7..just extract a certain amount and replace with new..change filters only on a scheduled shutdown. Just my (now worthless) .02

 

Their IS in fact a baffle that runs all the way around the sump area about 3/4 of the way op the wall.
