Oil pan bolt stuck, now stripped by impact driver

Trying for a long time, 4 different impact drivers, after socket wrench. Plenty of WD 40. Last week, spent $350 on the Milwaukee snub nose impact driver. I am in a wonderful county campground (30 Amps,
but beautiful and $18/night ), and caretaker is a mechanic-nothing will loosen this thing. I tried drilling the top of the bolt with a titanium bit, got nowhere, but it was not a left turning bit.
Can I drill a new hole and use a top notch plug? Three shops were weeks out for an appointment. I need to be able to change the oil myself. ($$$)
Welcome all advice! Want to wander to Padre Island, TX, very slowly ,so that hurricane season winds down.

Make sure you replace the plug with an easy drain plug valve.

You can use a dip stick, oil drain pump.

That's all they use on boats.

Its called a oil extractor.

If I remember rightly, those bolts are supposed to be softer than the Oil pan as a precaution against striping the threads. How much would it be to just replace the Oil pan? Seems like the kind of thing that might not be that expensive or possibly even available from a wrecker. Seems like it might be a better way to go that drilling a new hole.

Ive had success by cleaning up stripped bolt heads with brake cleaner and then using epoxy (jb weld) to glue a 3/8 drive socket of the appropriate size over the rounded bolt head

Go for a beach walk and then take a ratchet and remove the bolt

Get someone to come and weld a wrench on the plug. I'd do that before I drilled it.

Wow! I've never seen a drain plug that stuck before. The only way to put a new plug in another location is to remove the pan. There are kits that are actually made for transmission pans to add a drain where there wasn't one. It includes a large nut and washer for the inside and a hollow threaded bolt for the outside, mate them together in the hole you drill and then thread the drain bolt into that. Otherwise, the metal is too thin to screw into.

Before you resort to destructive methods. I'd get a good penetrating oil (PB Blaster Krull Etc). Spray the oil once a day for a couple of days and give it time to penetrate. WD40 is more of a water displacer than a penetrating oil. Heating the bolt before spraying the penetrating oil wouldn't hurt either.

An additional alternative is to heat the bolt pretty hot, then douse it with cold water. The sudden temperature change often breaks the rust or whatever is causing the problem.

Finally, if you haven't done it yet, use the impact wrench to try to tighten the bolt for a few seconds. It may break the bind enough that when you try to loosen the bolt it will kick free. But do this after the penetrating oil has had a few days to work.

Be patient. A few days of a good penetrating oil should work. Good luck! Also, torque when you reinstall is only 19 foot pounds - pretty light.

I think twinboat has the right idea, leave pan plug and suck out oil, call a marine shop, they probably sell oil pump kits.

When I have had bolts that couldn't be loosened with a torque wrench a long breaker bar worked every time providing enough room to use the bar.

The oil in the sump is high enough that is will act as a heat sink/coolant so that you can weld a hefty nut to the stripped plug head and if you grunt on it hard enough while it's still hot from the welding it should break loose. I'd replace it once you get it out with a Fumoto type drain.

I'd be worried that even if you can drill through the stripped plug, you'll most likely introduce metal drilling chips into the oil sump, and nothing good can come from that. That can turn a small problem into a huge problem.

When I had boats we used something similar to this one to extract the oil.


I actually used it today for the first time in 10 years. I changed the tranny fluid on my CRV doing the double drain and fill. I added a little to much so I sucked it out.

56safari gave some very good advice. The penetrating oil and heat will do the trick.
I will add that using a quality 6 point socket (Snap On) with a long breaker bar will also help.

You will never be able to suck all the oil out through the dipstick. The dipstick tube is at least 2" above the bottom.
