Car Forum / Jeep / April 2004Recommended torque for oil drain plug (94 YJ)
Subject about sums it - what's the recommended torque for the oil drain plug (94 Wrangler) - 25 '# ?. Thanks. - TK 25 foot pounds it is.... > Subject about sums it - what's the recommended torque for the oil > drain plug (94 Wrangler) - 25 '# ?. Thanks. - TK That really varies, but about 15 to 25 is normal. The washer makes a big difference. You are 'supposed' to use a new copper crush washer each time and they need about 25 ft lb to compress. If you use a nylon washer, they use a little less and if you re-use either, then drop it down even more. Once the washers are compressed the bolt needs to be tightened really carefully or it will quickly go too tight and strip.

Been using the same bolt since 93 at about 3-4 oil changes per year. Not one drip yet. :) cept mebby me. I can be a real drip.  SignatureDougW I use kite string.

[quoted text clipped - 12 lines] > -- > DougW Well you know, I decided I wanted a dry engine, LOL! Ya right! But it is... and I use a new one most oil changes just because.... I have a pack of them in my kit box right now. I have done literally thousands of oil changes professionally and have never had more than a couple come back with a drip and those were in garages that 'didn't' change the ring with the oil change. Most places I worked insisted on a new ring 'every' time like the makers insist on so the oil change is warranty valid, let alone liability if the old ring finally splits. That is probably the most important washer in the whole engine! Go too tight or use it too many times and it up and splits on you and the oil all pisses out. Yours is now 11 years old and is copper. Copper does stretch and compress to a certain extent, but when it gets old it can finally just stress/stretch crack. Then if you are unlucky all the oil blows out and you kill the engine. Washers are freaking cheap insurance, they sell them in 1 years supply or 4 packs even........ There is a thread over on rec.autos.tech on the same thing and some Volvo owners among others said the same as you. I looked up their vehicles, actually I googled oil crush washers and Volvo came up and Volvo insists on a new ring every time for their vehicles, so they have voided their warranty if they get caught. Or just cooked the engine if out of warranty.... Sure you save 15 cents on an oil change, but........

Yep. > Go too tight or use it too many times and it up and splits on you and > the oil all pisses out. So far no splits, but you are correct, I should replace it at the next change. Easy enough to order a few with the next parts delivery. > Yours is now 11 years old and is copper.

Some of it is copper but the surround appears to be more of a brown rubber. > Then if you are unlucky all the oil blows out and you kill the engine. Only if the bolt falls out. On mine the threads alone will hold back hot oil. Don't get any drips till I turn that last little bit on the bolt. I'll throw a new one on next time, couldn't hurt. Just finished replumbing most of the hoses and using a little permatex gasket maker to fix those hard rubber hoseends that tend to break loose. SignatureDougW |
