Oil leak?

I might be wrong, but I've been told that when the truck runs its all life on dino oil, switching to synthetic is not a god idea. Synhtetic oil will wash all goo built-up through the years and start circulating it through the system. I is better to keep the goo where it settled down instead for trying to lubricate the engine with it.

Also old seals will have micro-cracks filed with the same goo. When washed out the seal might start leaking oil through these cracks. My truck is 22 years old, 318k miles running all life on dino oil changed every 5k miles. No leaks.

 

Did you replace the crush washer on the oil pan? If not... you should with every oil change or it will drip. Have you considered "High Mileage" oil? It is designed for vehicles over 75,000 miles and has a conditioner in the additive pack that helps "swell" seals to reduce this phenomenon which is common.

Other areas to check are valve covers and oil pan gasket.

 

171,000+ miles using Nothing but Mobil 1 (5w/30) No leaks, drips etc. Ever.

 

It's probably left over crap that's been sitting on your skid. I have to park over cardboard for a week before all the oil finally drips off from the mess I made after an oil change. Hate where Toyota put the oil filter on these trucks.

I would never recommend high mileage oil, it swells your seals and if you ever go back to a regular oil, your seals will unswell and will leak worse. Got a leaky seal? Replace it. Don't use high mileage oil.

 

Agree...that's one of many reason's I change the oil/filter myself. It takes a bit more time, but I remove the front skid plates to prevent it from marking it's territory afterwards. It doesn't seem to matter how careful I am removing the oil filter, it still spills down your arm, etc.

 

I don't tolerate this sort of thing anymore. Buy a mighty vac

$125 MV7201 Mityvac 7201 2.3 Gallon Fluid Evacuator Extractor and Dispensing Pump, Push Button, Manual Operation, Chemical-Resistant Polyethylene, Automatic Overflow Prevention, Quick-Drain Spout, Large Base

MV7201 and never crawl under your truck again. Drop line into dipstick tube and vacuum the oil out... replace filter.... add oil and BOOM YER DONE.... For me it was when I had the oil from my oil pan hit my drain pan and splash all over my garage floor resulting in me spending another hour degreasing the floor after the job.... I said never again. That or get the oil catch pan that has a riser with a basin to catch all of the oil close to the source to prevent splashback....

 

Actually the issue is not in the drain plug - this one opens straight down. The oil filter is on the side of the engine block with casting parts under it. Removing the filter will always result a spill on the block (unless you remove the engine and tilt it to the side).

Now I don't know where the dip stick hole ends, so I'm not sure if you can suck all the oil from the very bottom of the oil pan. The oil drain plug is in the lowest point of the oil pan, so when you open it, the only oil left in the engine would be above the oil pump. But wen you remove the oil filter, most of that oil will spill out so that would make oil change pretty much a complete swap.

 

When I took my filter off it made a mess and got all over the cross member and skids. It was dripping for about a day, I hade to take off the skids and thouroghly wipe everything off and now it's good.

 

Use the old sandwich bag trick. Once the oil filter is loose, before oil leaks, put a sandwich bag over the filter and spin the whole thing off. Let the bag catch the oil and the filter and pull it out. You probably won't get all the oil, but you'll get most of it. I use the same trick on my dad's tundra 4.7 as the oil filter is above the skid on that too

 

Appreciate the tip! You get the "Smart as a Hog" award for that one! .........in Arkansas, that is a compliment

 

2 things to consider. I did this before I began pumping it via the dipstick.

1. Cut a water bottle in half.... wedge the bottom half under the "casting" and remove the filter. The bottle will get about 4oz of oil in it.... clean the casting and carefully remove the water bottle with oil in it... done
2. Take a piece of 5/8 hose and attach to the bottom of the casting... yes... that is a nipple... drop the hose down to where you are catching the oil from your pan and bazinga.... problem solved.... save hose for future use.

 

Anal much?

 

Just because someone is meticulous with their maintenance procedures does not make one "anal". I digress...
