WTF! my oil cap is stuck.
 
aight im not going to admit im to weak to remove my oil cap. im pretty fitted. righty tity lefty loosey correct? is it possible since i just ran the car the pressure is causing it to be so tight? WTF!!!!!!

ohh and do i check oil lever cold or after the cars warm. i notice when cold its low. right when i start the car its full. and after its warmed up it would be low if i check it too slow. if i plug the dip in an pull it out fast ill be near full.

daym this shit is pissin me off.

turn it to the left.. sometimes mine gets really tight too. if you have to use a shop rag to get a better grip on it

you check the oil level when the car is off, it shouldn't matter cold or warm it should read about the same regardless. you should be letting it sit for a second or 2 to get an accurate reading not stabbing it down and pulling it out as fast as possible.

no, there should be no residual pressure in the crankcase, even if there was a tiny bit it would not hold the cap on. if you did tighten the cap down when the engine was warm last time it may have cinched itself down tighter so i suggest just snugging it down next time as they do not need to be cranked down.

try using a rag for additional grip on the cap, if you still can't get it off grab a large set of channel locks or plumber wrench and use that to get it off and hopefully it comes off in one piece.

good luck.

Well from what i read, and know. When your car is cold the oil is sitting so i would figure thats why you get a low response when you pull the needle. As for the high level, i think thats because the oil is already circulating and its the oil level is much higher.

i dont know how your oil cap got stuck, i dont recal the oil cap having any pressure of any kind. For all i know, i lost an oil cap once, while driving it just poped right off. So yea, i tend to check my oil level, or anything that has to do with oil procedures when its cold. Unless its something more comprehensive, i dont go checking the oil when its hot.

just relax dude, im driving around with a busted 'oil level' gauge. lol...~

RotaryEvolution 08-15-06 06:53 PM

the reason you don't check it and why it is high when the engine is running is because the oil circulating and sloshing around. picture it like a pool in the morning when no one is in it, the water is calm and level, when you have everyone playing and splashing around the waves will cause the water level to register a bit higher at times.

push down and turn

mine sticks occasionally, enough that plenty of strong people who have tried.. couldn't get it to turn. however, if I push down on it while turning (like a medicine bottle?) it comes right off.

I don't know if it's designed that way or that just gets around whatever problem causes it to stick

Good luck getting it off, my 2nd rex did it all the time, i had my elbow rebuilt and i could never get it off my-self, i always had to get someone else take it off, even with a shop rag, i had to take it to hand tight, then back it off like a half-turn. At one point, i had to pour the oil down the dipstick hole to get some in the motor, since i couldnt; get the cap off. so dude i understand were you are coming from, and good luck!

alwayssideways 08-15-06 08:23 PM

I have the same problem. I use a shop rag to add to my grip. If that doesnt work i still use the rag and a nice pair of channel lock plyers.

nickn505 08-15-06 08:34 PM

Even after you turn off the engine, wait a few minutes before you check the oil level. it will still be innacurate because warm oil expands, and oil will still be dripping off the engine parts. This is why most full service stations don't check oil anymore, the readings are useless. As warm oil expands, when it's cold it contracts (cold mornings. Wonder why your readings are so far off?) It shouldn't make too much of a difference though.

ericgrau 08-15-06 08:48 PM

Actually the reason is to let the oil settle, not so much because it expands when warm. The Haynes manual recommends 15 minutes, though 5 minutes is probably just enough.

TonyD89 08-15-06 08:51 PM

Lol. I get the same problem on my Honda. Don't over-tighten when I put it on but it is a mofo to get off! I think it has to do with the synthetic caps.

Steel 08-15-06 09:16 PM

yeah i noticed on the screw on caps that they like to get stuck. The tab-and lock ones like on toyotas are beautiful though.

TonyD89 08-15-06 09:25 PM

Figures, Toyota.

7dust 08-15-06 09:27 PM

Don't be a pussy.

Just sayin.

Steel 08-15-06 09:27 PM

AFter working for toyota (lexus) for almsot a year, then transfering to honda, ive figured out one thing:
Toyotas are perfect.

SirCygnus 08-16-06 02:35 AM

tap it with a hammer to get it loose.

Madrx7racer 08-16-06 03:36 AM

you need a man to help you. LOL



It happens to me all the time......I use a screw driver and something else (usually my ratchet) to tap it..........set the screwdriver on the cap and lightly tap to your left and it will eventually break loose.

lchaidez 08-16-06 10:09 AM

lol...

darksider 08-16-06 02:55 PM

i usually check my oil level when i get gas and what not. this is the first time i did it in the morning after the cars been sitting. it was really low and was why i wanted to add oil. after letting it sit last night i concluded if i let the car sit a day (when i sleep) the readings on the dip is real low. lower then the middle mark! is this normal?

update: the oil cap came off with ease today after i let it sit. hahahhahahh i need to go work out some more.

I used to have the same problem with the Mazda plastic oil filler cap on my 90 GXL. I then bought a replacement metal oil filler cap on ebay, and no longer have problems taking the cap off.

put a shop rag over it and use a large set of slip joint pliers on that cap

RotaryEvolution 08-16-06 03:46 PM

now this thread is just getting redundant..

StarScreaM2k1 08-16-06 04:22 PM

you can be ghetto, and drill the Cap and tap it for some Fitting! LOL now that would be ghetto shit! LOL just joking tho :D

lchaidez 08-17-06 09:58 AM
