    98 Camry 4 cy. - can oil completely leak out of engine and oil pan (regardless of where leak is) and absolutely not hear rocker arms or something chatter loudly enough to indicate low oil, plus not have oil pressure light come on?



    UPDATE



    Had mechanic to inspect the engine. (140K) He found zero evidence of oil leaking from oil pan (or plug) or value covers. He removed the oil pan and also the value covers.



    There was evidence of some (not significant amounts) of metal in the pan, and there was, what he described as substantial sludge in around the rockers after removing value cover.



    He flushed the engine twice and said that the oil remained to be dirty looking even after the second flush.



    He said that although the engine would start that it had very litte power.



    The engine light did not come on at anytime. He didn't have a manual gauge that could use. So, ultimately, the actual pressure isn't known.



    He said that without really disassembling the engine in a more profound way...that he couldn't really tell what happened.



    He said that he found no real physical evidence that somebody put sugar in gas tank, but that if the sugar was liquified, then it would make it more difficult to detect. He checked the fuel filer..and found it to be in good working order. So he said that most of the time, sugar will be visible in filter before entering the engine injectors.



    The oil pan and value cover gaskets were replaced in 2007. The EGR value was replaced along with Timing Belt in late 2006 (approx 100K).



    The only conclusion is that it is possible that the engine has died from sludge. The machanic said that he's never looked at an engine that had no visible signs of oil leakage externally or through exhaust and yet most of the oil was gone.



    He came to that conclusion because of the visible sludge after taking off value cover... and the fact that 2 oil flushed later, the fresh new oil appeared to be very dirty.



    We still are at a loss!

Firstly! Yes alloy engines will run quite along time with little or no oil!
oil warning lights are a waste of space!
if it fails to light up you dont have any warning do you!
i would like to know from you a little more of the story! as to were you driving at the time ?? did it have leaks prior & is the plug still in the oil pan?? or was motor burning oil
Cheers Rob.

    oil sludge buildup is due to mixing different brands& not servicing motor regularly!

    it may burn oil when temerature rises if valvse & or their guides are worn & stem seals leaking & you may not have noticed the smoke!

    The oil light [ pressure switch] may be faulty [ no light]

    id say it has worn or brocken oil rings on pistons & withh slude present It needs a rebuild as i would not truast it to be reliable atall

    Cheers Rob

Unless the drain plug was leaking, there really is no way that all of the oil can come out of the pan, as the oil level is below the sealing area between the pan and the block. With that being said, you will normally not hear any noises untill the oil pressure drops to zero, when there is not sufficient oil at the pickup of the oil pump. After that, and the noises start, you may have internal damage.

I have a tundra 06 an it does a cliking sound .it comes from the motor. i check everything around the motor and nothing is loose i wonder if there is something loose inside.


The problem is probably a loose rocker arm or a broken rod. You can easily access the rocker arms by taking top cover off the engine. It should be 6 or 8 bolts and looks like an upside down bread loaf pan. There will be a little bit of oil (assuming the engine is off) but it shouldn't be too messy. There will be a number of rockers which are levers with springs on one side. One bolt should hold down each rocker, just make sure that none of them are loose. Since it is a "V" engine (V6 or V8) there will be two of these covers, half of the rockers under each one.

If all of the rockers are tight (don't crank them down excessively just check to see if one is very loose). then it might be a broken rod. To remove the rod you need to remove the rocker arms one at a time and pull out the rod with a special tool that you can probably get from your local parts store. When you find it they can also sell you a replacement rod.

If you want to narrow it down you can turn the engine on with one sides cover off (but hold a paper towel over the rockers or you will get sprayed with oil) and listen to see if you can hear which one is broken.

I HAVE SAME JEEP SAME PROBLEM...I have found out after research that all these jeeps like yours and mine have a common problem with engine clogging and the valves sticking and the rocker arms coming off.....This is true I pulled my valve cover off and the rocker arm had come off because the valve was stuck ....Pressure between the rocker and the cam and the valve is the only thing that will keep the rockers from falling off......And when the valve starts to stick the rocker falls off.....This is sad but true.....Also it is badly clogged with black chuncks of burnt oil....I dont know what causes this other than the wrong weight oil....but I only used the wrong oil maybe 2 times...
There should be a recall on these because the rocker arms shouldnt come off.....I think the rockers are wrong from the factory....I am a level 2 chrysler tech.and also ASE certified.......It makes me angry that they built these so weak !! ....All you can do is remove the heads and have a complete valve job done and clean the oil pick-up tube in the oil pan as well....then a complete engine flush..
.....ONLY use 5w20 weight oil also........If you dont have the cash dont tear it down cause I almost guarantee you have the same problem as I.............Hope this helps.................Metalpoet

I have no oil pressure in the car we pulled the valve cover today and found 6 of the rocker arms were not installed, we havent pulled the other cover yet however with this not installed would this affect...


Hi,
are you serious? Aside from that question. If there are rocker arms missing it could affect the oil pressure. Are the oil feed holes in the area of each missing rocker plugged off?

Perhaps I had better back-track here. If the oil lube system has no restrictions in it then there will be minimal oil pressure developed. The oil pump will be pumping oil to the lower end of the engine and that will be where oil press if any will be developed.

The rocker area has drillings which restrict the oil delivery from the pump, however, the rocker arms themselves offer resistance to the oil supply and the oil must have enough flow and pressure to form a circle of oil within the rocker arm and thus keep it clear of the shaft. The oil flow goes through the rocker arm, and down over the valves and pushrods,(if fitted) and drops back down into the oil pan. Different set ups can be used, but that's a basic configuration.

The engine lubrication is designed with certain resistances, and they in turn affect the flow of oil and the pressure developed by the pump.

Good luck.

2002 toyota 4 cyl camry, 112000 miles on odo, emits blue smoke only on start up, uses no oil. Fix?


I would not bother. Usually this is valve guides/seals wearing out, but if that is the only problem, I would not worry about it. When it sits, the oil in the rocker arm area is leaking down into the cylinders, then when you start it, it burns off.
I would not do anything until you start using a fair bit of oil, or something breaks.

Oil consumption, rattle, engine noise


Check under the hood and inspect the valve cover gasket. If it's bad it would explain why you don't see any leaks on the ground because it's probably burning off on the manifold. This ticking you're hearing is a lack of lubrication to the rocker arms. Apart from the valve cover gasket, you should get under the car and inspect the oil pan and oil filter for seepage. Best of luck on your problem.

It could be a rocker arm as well as a lifter or even a rod, you need to determen ware its comming from top end or bottom end. With engine running take a long screwdriver hold the handle end to your ear and other end to rocker cover the whole length of cover, both sides if there is a loose rocker you will hear it, same on oil pan if you suspect its a rod. You would be surprised on how much you can hear thru that.
