You have already received some good advice, but I wanted to add that if it is engine sludge you may have other signs. Check your oil level to see if your car is consuming oil. If your oil level is dropping dramatically after adding oil and you do not see any visible signs of oil loss, it could be sludge. Sometimes the check engine light will come on, but at that point you could have some signficant engine damage. Also, sometimes you can actually tell it is sludged on the dip stick (thick chunky oil). The only way to tell for sure is to have the valve cover pulled.

Thanks to all that have replied.
Is there a dramatic difference in oil consumption between
(a) valve stem seals leak
versus
(b) engine oil sludge ?
If there is a valve stem leak, how much oil is typically consumed ? a quart every 3000 miles ?

Having had the faulty valve stem seals (twice on the same car), I can say that there will be NO noticeable oil consumption. As I said earlier, the second time it happened (at 102K miles), I did not have the engine repaired. I kept the car till 111K miles, and it continued to use no oil between changes.
Sludge is a much more serious issue -- as to whether there's excessive oil consumption, I think it depends on how much sludge there is and where it's concentrated.

It really depends on the severity of the valve stem seal (and/or guide) leakage. I've seen engines with valve stem seal leakage bad enough to burn a full quart of oil every 500 miles. One observation that can be made is to follow a car suspected of having a valve stem seal problem down a moderately steep hill. If the suspect car is trailing blue smoke when the piston rings are vacuum loaded from little or no throttle, it's because motor oil is being drawn past the valve stem seals into the combustion chambers. When smoke under negative load happens, it's time to pull the cylinder head(s) and have a machine shop rebuild it/them.

Not sure if this has been asked (sorry if it has). Can 2005 camry LE's use this fuel. I've checked the net and it's mostly trucks and vehicles made by GM, some others. No sign of honda or toyota vehicles. Thanks.

No, the Camry cannot use this fuel, including the newest models. It says in the 2004-05 manuals that gasoline containing up to 10% ethanol can be used.

fuel pump prime

Is my 04' camry supposed to have a fuel pump prime, because on all of my other cars it primes but not this one, but it does run good. If you turn the Ignition to the ON position, do you hear a small whiring from the back of the car for a few seconds. Im confused becasue according to my manual, to check fuel pressure you have to have the prime. ANYBODY CHECk for your prime, regarless of year. Although i have a 93 but it isnt suposed to.

Yes,the noise is the fuel pump. Fuel injected cars will prime when the key is turned on.Why are you concerned with fuel pump pressure if there is nothing wrong with the way the car is running?

Perhaps you dont understant. My camry doesnt have the prime. Every year, my manual suggests checking fuel pressure and to do that, i need the prime according to the manual. I know enough about cars to the point where i know what is going on.

At the risk of alienating you (and no one is implying you're not knowledgeable), if your fuel pump wasn't able to achieve prime when the ignition switch is turned on, your engine wouldn't run at all. There has to be a minimally nominal 32-35 psi for the injectors to work. Whether you can actually hear the brief groan in the cabin as the fuel pressure spools up may be related to your own hearing abilities depending on age, prior illness, etc. You might try removing the fuel filler cap and remaining close by the open fill tube while someone else turns on the ignition switch from the driver's seat. (ONLY attempt this procedure in open air!) By having more immediate access to the noise the fuel pump makes in operation, you may be able to verify the fuel pump priming up to nominal pressure. Regardless, if you can start and drive the car, the fuel pump has achieved prime.
