Oil pan drain plug mess

[Ibaloi]

I had my old b2200's oil change 5,000 kilometers ago in a shop thinking that everything was ok. I usually change the oil myself, but there are days when I can't. When I was about to change my oil the other day, I found out that the drain plug won't unscrew! I tried everything to take it off but even Bruce Almighty can't help me with this. I suspected that the shop mechanic was the culprit, since I peeled off a thick layer of silicone sealant before I could fit the wrench, and at the turn of the wrench, there was no resistance at all! It just went round and round. Anyway, I brought the truck to a reliable shop and the only solution was to take off the oil pan and try to remove it. They removed the oil pan and tried to pull off the plug, but still it held its ground. I went around to look for some surplus oil pans but there was nothing in all the shops. The solution was to get an old oil pan, cut around the drain plug, as with my oil pan and weld it in place. That's what we did and I am happy with the results (good welder). Guys, never ever take the tiny oil drain plug for granted, make sure that the persons changing your oil know the directions on which to unscrew the plug. (I have noticed that some mechanics tighten bolts then go back to unscrew it,thinking that further tightening a bolt would loosen it, probably this is what happened to my pan). Taking down the oil pan is a lot of work! In my case, they took off part of the steering component and a stabilizer bar(that's a lot of screws!). One advantage of taking off the oil pan though, we were able to wash and flush the engine with oil! When everything was over, I drove home and checked the dipstick, it was as clear as day! I noticed even that my truck seem to have regained its lost hp after 11 years! So, on your next oil change be very vigilant and always remember, it's always the small things that can cause the worse problems.

ibaloi,

thanks for the info.

Sa aming fuego, tatlong tao lang ang pwedeng gumalaw sa makina, ako at yong dalawang mekaniko.

Same thing happened to my corolla before... loose thread na so ganun din welding na lang nung part na yun instead of getting a new oil pan.

Culprit dyan is reusing the washer nung last oil change. Never reuse the washer for the drain bolt kase crush washer yun. designed for one time use only. Pag ginamit ulit yun you would have to tighten it further causing the loose tread to occur.

Thanks too guys! Everything running fine now, no leaks so far.:D

Ma'am,

The trick to seized bolts is by heating real hot,tapos yun dali na tanggalin

[Mile2]

heat it or use ball pin hammer, it should loosen up a bit. Even rusted or stucked up bolts in my experience can be loosen.

if the bolt is somewhat rounded already, you can just weld another nut on top. Wondering why they have to cut and weld oil pan not unless the oil pan thread is worn out.

You can also have your machinist make you graphite or copper washers, your machinist would have so much material just lying around, as for me I just turn those bolts handtight. That is how my grandpa, and dad does it.

First you should get your self an extra for emergencies as these bolts get
stolen. Then using these extra drain plug you can shop around for washers that will fit or you can fabricate yourself from copper sheets. Others uses bicycle tire interiors for these, I prefer copper.

Check out your neighborhood scrap dealers for materials or just look around
your house.

I may look weird but I tell you these drain plugs get stolen.

Always have an extra.

thanks po ng marami....tama nga talga na dapat ay may reserve...dati kasi napudpod na yun tread ng nut ko tpos buy me sa honda...bibili ulit ako para may reserve

marami kasing shop na nagha-hire sa mga walang knowledge sa basic mechanic dahil tipid sa sueldo. Konting training lang sa pagtanggal ng drain plug at paglagay ng oil ay puede na. Your are right, you must aware kung sino ang mga gumagalaw sa sasakyan mo.

[speedyfix]

actually, the problem there is the mechanic. if makita nya na may tama na yung plug, washer or thread of the oil pan he should inform you asap para wala na iba madamay.

[H1Tman]

when careless mechanics don't use lifters. minsan baliko pagkabit.

[speedyfix]

what does use of a lifter have to do with putting the bolt on correctly?
