holy sh*t, dripping oil from drain plug
hey guys, I changed my oil yesterday evening, and when I was unscrewing the oil drain plug, I noticed a few small "strips" of metal coming out, like the plug was cutting the threads in the hole... Then, while tightening the plug, it would not tighten all the way, in other words it would keep turning and never get fully tightened. Well, as it was getting dark, I filled up with oil and left the scene, hoping it would be sufficiently tight to hold oil. Today I find a 1.5 square foot puddle of havoline synthetic under my car. Obviously a slow leak, but a problem nonetheless. Should a new drain plug solve the problem? Any help would be appreciated. BTW, this is on my old school prelude, not my TL, but I'm not a member of any Prelude sites or else I'd ask there. Thanks!

maybe you need a washer on the drain plug, i know the TL has it, that is what stops it from stripping out. you might be lucky enought to just add the washer there if not already there to solve the problem.

definately sounds spripped. worst case just get a tap and make the whole bigger to a drainplug that will fit, or replace the oil pan.

You should change the drain plug at least every other oil change on ALL hondas, they tend to leak for some reason, but it sounds like yer problems a little bigger than just a new plug. BTW eight bucks????? Bunch of thieves.

I believe you're supposed to change the washer with every oil change. The idea is that the washer is some soft metal (like copper?) which deforms when you tighten the plug, making the seal. I can't imagine why you'd have to change the plug. It doesn't deform anymore than the lug bolts when you change the tires.

I never change the drain plug or washer on any car and I've never had a problem. As long as you screw it in properly and don't strip it, it should last for the life of the car. This includes NOT over-tightening it, like many people do. I don't remember the numbers off the top of my head, but the service manual specifies how tight it's supposed to be -- get a torque wrench if you must.
However, I did buy my TL used, and I just did my first oil change only to find out that the last person to change it ruined the drain plug (and the oil pan in the process). I'm getting it fixed at no cost under warranty, but otherwise they said the oil pan itself costs $150.00

I tighten the drain bolt 3/4 turn past where it's finger tight. About the same for the oil filter as well.
My torque wrench is one of the big 15" ones with the 1/2" socket...it doesn't fit under the car, nor does my 3/8" socket kit fit it

Definately sounds stripped....start looking for a new oil pan....thats the only correct way to do it...teflon tape won't hold for long and when you find out it fails it is usually when the engine seizes on the parkway

OK....i've post this several times.
Crush Washer = So you won't strip the thread NOT TO STOP OIL LEAKS!!!!
You are suppose to change the crush washer every oil change. The reason why some of you don't is that you guys don't "CRUSH" them. The point of hte crush washer is that you don't over torque and fu%k you the thread on the oil pan. The washer get's crushed *compressed* to prevent this. Once you crushed a washer, you can't crush it again. So you need a new one. Most of use don't apply enough torque to crush the washer, so we can most likely use it over and over, because it hasn't been compressed.
At this point, nothing is gonna save you now, but experience. You will goto the dealer and dish out some cash for a new oil pan. Becuase that's the only thing you can do. Now you learn to use a new crush washer everytime.
There might be a cheaper way then dish out 150. Try to bring it to a metal shop or molding shop. What the shop might do is to take ur oil pan, patch up the entire hole with a metallic solution, and thread a new hold. I know this can be done, i do'nt konw how much it cost or the correct term of the proccess.
You can try to do it urself if ur capable of it. Try to goto Home Depot and ask them for a metallic solution and describe to him what ur trin to do. The item should be in piping *copper and metal* or the plumbing dept. Buy it, go home, pour in the solution and mold it to seal up the hole. After it's finished, sand it down. Here is So. Cal, we have a store called "Harbor Freight Tools" they sell, alot of neat stuff and tools that you wouldn't find in home depot. They have a tool design to thread out holes. So you drill a hole in the pan, and use the tool to thread it.

thanks for the excellent advice... though you may not have noticed, this problem is on my Honda Prelude- no washer like on the TL unfortunately. Though I may want to add that on my own now. Looks like I'll probably need a new oil pan. damn.

In my younger years I had the displeasure of working for Valvoline
and we replaced Honda plugs every time. Its a Honda only problem and even though its not always necessary its a good idea to do it as often as possible. My uncle owns a honda shop and they do the same thing, almost every car they see with a drip just needs a new plug, he told me the dealers usually do it too. Im on my sixth Honda and I havent had any drips since I started changing the plugs. Again, its not always necessary but its PREVENTATIVE maintenance, I get it all free so its no big deal for me but give it a try. It has something to do with overtightening the old plugs and a new plug or washer is a good way to make sure you dont.

cool, I'll try replacing just the plug first, before shelling out the dough for a new pan. I should be able to hopefully retain most of the fresh oil too without draining too much.

Look closely - your '92 Prelude should have a crush washer. ( It may be 'crushed' up against the bolt head so it's hard to differentiate). My '89 Prelude has a washer - which I've never changed btw.
