#3806 of 3858 Bolt Pattern Match for spare rims
Dec 28, 2011 (2:45 pm)
We have a 2009 Toyota Corolla and are looking for used rims for the snow tires.
What other years/cars use the same rims?
I believe they are 15x6J rims and I was told by an auto salvage yard they are 5x4" bolt pattern.
A Toyota parts department said the rims are the same as the 03-09 Corolla and 93-97 Celica.
Then I read in your forum that they are 5x100mm bolt pattern...
#3807 of 3858 My 2004 Toyota Corolla is humming

I have a 2004 toyota corolla sport is making this loud humming noise that sounds like and exhaust leak. But it's not. I had the whole exhaust checked for leaks. Could it be a wheel bearing ass. I cant tell if it's in the front or the back while im driving. I just know it's loud as hell.

#3809 of 3858 Oil Sludge in Corolla 1998
Jan 22, 2012 (9:37 pm)
I have the above car and always did timely oil change. Recently I picked it up from a shop where the bumper was being repainted. Upon leaving the shop i drove quarter mile and the oil light came up, and the temp gauge went up to about 40% (normally it is at 25%). I checked the oil and the dip stick showed very very low. So I added one and half quart and brought the oil level to slightly above normal level normal. However, the oil light still remained on and the temp. gauge continued to show at 40%. I slowly drove home about 6 miles away. Next day I towed the car to the dealer who, after inspecting told me that there may be too much sludge so it would be too expensive to repair. They would have to open the engine and then clean it out and reassemble. This would cost more than the value of the car.
1)My question is how could the sludge build if I did regular oil changes?
2) If I have them take off the oil pan and clean the screen would this help?
3) Can anyone think of any way (besides dismantling the engine) to confirm that the sludge is the problem? If that turns out to be true than I will have to junk the car.
4) I was wondering about foul play. The guy who had it for 3 days to paint the bumpers, was quite unhappy because I had insisted that he do the paint work again because the bumper color did not match the rest of the car. The car was in excellent shape and very well maintained, therefore I was puzzled this happened right after I left the body shop.
Any ideas would be greatly appreciated?

It's kind of hard to comment without some hard evidence. The best way to see if there is oil sludge is to remove the valve cover. Was this done? If not--if they just sniffed at it through the dipstick or something, that won't do. I'd certainly pay to have the valve cover removed while you're standing there and then you'll know the truth of it. If the sludge is really there, and it's incredibly thick and gooey and very extensive throughout the top of the engine, then that might be the end of the road, yes.
But before making huge decisions like this you need really good verification.
Typical oil sludge is shown here: notice how thick and black it is.

Thanks Mr. Shiftright for your response. I will talk to the service guy about removing the valve cover. Its a good idea, wonder why they did not recommend that?

Sir, after reading your post, I must say it sure sounds odd for this to happen right after getting your car from a shop. I have work on cars over 30 years and know alot the scams that go on. Do not remove your valve cover untill you do these test first. 1. Disconnect your positive battery cable from battery for approx 5 minutes then recoonnect it, and start your car and see if that stoped your oil light from being on. Doing that will cause your motor computer to reset alot of your motor settings, I know doing this works on resetting your engine check light, So its worth a try. 2. Drain your oil and inspect it for having a odd color and/or strange particals in it or being gummy.. If so than someone may have put something in your oil to make a bad effect on the motor. 3. Do a oil pressure test, its very easy to do, and if your oil pressure is proper psi. then theres nothing wrong with your engine oil pressure. And your oil light should not be on, if it is still on then your oil pressure sending unit could be bad or there is could be a clog right at where the oil reaches the oil pressure sending unit and stops the oil pressure unit from working correctlly which can cause your oil light to be on, So need to take out the oil sending unit .Its in the head or the block, ,just unscrew it out from the motor and crank the motor to see if oil shoots out the hole. And doing that may flush out the partical that could have been cloging it ,so the oil couldn't reach the oil sender unit correctlly..4. remove radiator cap and put a water tempenture thermometer in the radiator cap hole into the anti freeze, if can't reach anti freeze there , find a different place to let the thermometer touch the anti freeze like in one of the hoses or etc, So it will give you a reading. Start the motor and let it get to normal running temperture which is aporox 180 to 190 degrees for most motors, So if your thermometer reads correct then your dash gauge should not read hot. If it does your tempeture sending unit may be bad. So you need to do these test first because you can have sluge under your valve cover and your engine can still be fine and run ok with sluge. So just by removing valve cover and looking for sluge and cleaning the sluge.I don't think is going to solve the problem. If you had sluge I think you would have notice odd things happening with your motor and performence of your motor for quite a while not just it happening after you pick up your car from a repair shop. Pulling the valve cover and looking for sluge is just playing a guessing game, Do the test I mentioned and more testing from a good mechanic that knows what tests should be done, so you know the motor has proper readings and results. So your not playing a guessing game and know what needs done to solve this problem. Mechanic from Ohio.

Alex, I believe his car has the OBD-II diagnostic system, so disconnecting the battery won't reset his check engine light. He'll need the scanner to do that.
I do agree with you though, that the repair shop's explanation doesn't sound right.
Why do you think removing the valve cover is a guessing game? I mean, if you want to see sludge, what better place to find it?
Actually I suggested removing the valve cover in order to challenge the diagnose of the repair shop. So let's put it this way---if there's no sludge in the valve cover, there still could be some in the oil pan (and how would the repair shop know that?) And if there IS sludge in the valve cover, than you know for sure there is sludge in the rest of the engine.
So, given the "verdict" that his engine was no good, I think removing the valve cover will either verify the repair shop's diagnosis, or put them on the spot to do some explaining.

I have a 98 corolla and deconnecting the positive battery cable for a few minutes, on my 98 corolla , works good to reset the engine light when it has come on, I have done this many times, and it works, And my engine light is no longer on, And I ask why at summit racing and was told when desconnecting the battery it makes the car computer reset the engine light, Sorry i sound harsh, but alot of toyota motors have sludge on the inside of valve cover and still run good like that, So if you remove the valve cover and see some sludge, I would call that more of a guess, because many motors that have sludge are still running ok with no problem, I have a 1993 camry with 270000 miles on it and it has sludge under the valve cover, And is still running I would say excellent. Yes it could be the sludge with his motor, but if it was I do not think it would have showed up after picking his car up from a repair shop, I think if it was sludge then his motor would have been acting odd for a while, and He even said he changed his oil regulerly so he should not have had much sludge. So why I still think its a guess about it could be the sludge if you see it under the valve cover, He said his oil light was on so he needs to have a oil pressure test first to make sure he has proper oil pressure. The End.

Also if his motor was not having proper oil pressure than that will make the motor run hotter because of low oil pressure, and he said his temperture gauge was higher than normal, So it makes sence to do oil pressure check first before pulling the valve cover to check for sludge.
