stripped oil dran bolt

[swell]

alright, so i recently bought my first 3gee an im heading to do the first oil change on the car, i put her on ramps to elevate the car an i begin tryin to loosen the drain bolt an notice it wont budge, i do a little asking around an find out most drain bolts are reverse threaded, so instead of traditionally turning the bolt counter clockwise to loosen it i am turning it clockwise, then i notice the bolt loosens an gives way an is now tuning...i continued to loosen that bolt for a good ten minutes...tried tightening the bolt back (another ten minutes) no success, now i have been trying to remove the drain bolt an once removed i planned on threading a larger bolt into the hole in place of the stripped bolt, anybody have any techniques on removing the drain bolt?

Damn dude, so you spent 10 minutes turning it the wrong direction? Then another 10 turning it the other way? Boy, you made a right proper mess of that. Try turning it the correct direction, left-loosey, while using a slotted screwdriver to pry the bolt away from the pan. It will probably work, but you'll have to spend a lot of time massaging it.

Honestly, I'd drill a hole in the pan to drain the oil and then run down to Pick-A-Part and get a new pan. It will be a challenge getting the new pan on with the gasket in the right position (use twist-ties to hold it in place and then cut them out as you put the bolts in) but it's probably the best way. I don't think you're going to have a lot of luck trying to thread a bigger drain bolt in.

I re-threaded one oil pan once. It can certainly be done. Since our Hondas use 14mm x 1.50 I would suggest going for a 16mm x 1.50. You may re-thread it with the pan installed but one issue would be how to get the shavings out of the pan. I took mine out and did the re-threading. Frankly, you may be better served if you can pull out another pan from a junkyard although you may consider that because of age (and operators' plain brutality) the threads may not be quite as good as new cut ones

If you re-thread it I would strongly suggest doing it from the inside out; my threads were a little more loose on the place where the tap went in first. Once the tap has gripped to the hole there is no problem; it will cut perfect.

Honestly, if you did that to your oil pan, I would ask someone that knows basics of working on cars to help you install a temporary oversized drain plug. Then, take it to a mechanic and have the oil pan replaced.

Whoever told you that most drain bolts are reverse-threaded needs to be slapped with a spanner and never allowed to touch a car. The only times you will see reverse-threaded fastners are when this type of threading keeps them from working loose. Your crankshaft pulley bolt is reverse threaded for this purpose. Some fastners on rotating parts of the trans are also reverse threaded. Regular fastners are lefty loosy, righty tighty. You can buy a special self-tapping drain bolt at most auto parts stores. It is not as good at cutting threads as a proper tap, but could work in a pinch. Don't expect great quality or a long lasting repair with these. Just my $.02 HTH

i would helicoil it or replace the oil pan.

I've never heard of this, but it just crossed my mind. Why couldn't he weld a nut onto the old pan and put the drain plug into it? Is there enough metal in the pan to allow it? I would sure try a few things before taking that pan off.

I did a google search on new pans for you, if you go that route. Rock Auto seems to be reasonable as to other prices. But I do not know the quality. But this will start you off if you don't go the JY route.http://www.google.com/search?client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&channel=s&hl=en&source=hp&q=1986+honda+accord+oil+pan+prices&btnG=Google+Search

Your crankshaft pulley bolt is reverse threaded for this purpose.

The Crank pulley has standard threads.

The only bolt I know that is reverse threaded on the 3G is the one that holds the Power-Steering pulley on the pump.

There just no meat there to do it. I think there is like 3 maybe 4 full threads on the pan. its a small piece of metal welded to the sheet metal.

New pan or weld a nut to the outside.

When i got my car it had a stripped bolt on the pan. I took the pan off went to the autozone or w/e. got a oil pan bolt thats close. went to the Hardware store got me a nut that fitted it and welded it inside the pan. And worked wounderful. If you cant weld someone well do it for 20 bucks....better then replacing the pan which is not cheap.

What's the difference between welding a nut inside or outside the pan, except for the pain to take the pan off?

[Oldblueaccord]

Really thats about it.

There's clearance inside to do it its just taking the pan off which might not be too easy for someone that cant get there oil plug off to start. The little tab welded to the inside is like only 1/4 inch thick.

if you cant helicoil it, i reccomend you replace it, unless you like leaks.

Well if you weld the nut on the outside i wouldnt think you would have a proper seal what so ever. Yes taking the pan off is sort of a pain. BUT inside the pan is the stock 1/16 plate that is threaded i had to heat that up and removel it. So i can have a flush surface to weld the nut in. I tell you i was close as hell going all the way threw. takes alot of practice i had to weld scrap metal. Are pans are paper thin.....BUT worked like a dream. Looked like no one touched it bisides the point you see a burnt metal look but who cares when its under the car anyway. I can post pics. Sicne i dont use that pan anymore. It was for my T25 setup.

The nut on the end of one of the manual transmission shafts is also left-handed.
