Burning oil?

[99SLE-S]

Just curious if these engines are prone to burning oil, think ours might be contributing to the valve cover gasket leak. =/

^^ yeah, every engine is with milage. Once you go beyond 150K Miles, you always do your checks while filling up gas!

Of course every engine is with mileage.
I'm asking if this motor in particular is known to have a common problem with burning oil, mainly valve seals.

check out my "Stupid Sludge" thread. I was using an excessive ammount of oil. Found out that I had a sludge issue when I changed the front valve cover. Changed gasket, cleaned oil pickup, hit it with seafoam in both crankcase and in the manifold. I have reduced my oil consumption considerably but still need to change the rear valve cover gasket and it needs another treatment of seafoam ran thru the intake. But I was using almost a quart every 1k mile and have cut that almost in half.
I have the V6 with about 150k mi on the clock. Even with oil consumption I am getting about 25mpg

I don't burn oil at 160k but I have been very good about changing it. My wife's 5sfe @ 145k does burn oil but I check it and keep it topped off for her. I plan on pulling the valve cover I just need to get a huge socket so I can take the spark plug tubes off. For now I think I will just run some seafoam through it and see whats up each oil change. I really don't think burning a little oil is a problem as long as you keep on top of refilling it. Hell my buddy adam drove 60k miles on a crown vic he stated burned equal parts oil and gas.

^^ understood.
I've got both a 5sfe w/ 111K miles no burning thus far. On my 1mz's w/ 115K miles nothing at al. On my other 1mz (ES300) thius far this engine has 220K miles, its to a point where its lil' lower than full by the time 3K miles roll for the oil change period. But still this car is kickin' strong.

But then again, I do a LOT of preventive maint. Its not just your maint stuff but also how the car was cared for beyond your ownership was the point I as trying to indicate over.

From what I have been told and in my personal experience using about a quart of oil every 3k miles is considered normal and acceptable ammount of burn-off on anything with more than 60k mi and some newer cars will burn that much brand new.

I check my oil 0nce a week and I have about 157k on it but it is all ways the same amount?

Oil consumption rarely gets to be an issue in a modern engine unless it becomes severe.
I used to drive an older dodge minivan for work and that sucker would smoke out an intersection while you waited for a green light. You had to check the oil at least once a week even though it was driven very short distances. Being that it was a company vehicle (and one that people hated to drive), the oil started to only get checked when it made noise from lack of oil. It still hammered on for a few years with perpetually low oil and NO oil changes. I finally made it throw a rod during a longer than average trip.
Moral of the story is that it is usually lack of oil rather than other syptoms of oil consumption which cause engine death. Check your oil!

That meant your car still good, Loss4wrds is right, check once every months, always keep 1 litre in your car for refill incase somethin happen, never knows, if dont drive much than check once awhile, but dont fill over the mark, everytime you go change oil ask the Shop to start to engine and let it run for 3-4 mins for Engine to suckup the oil and check again if it under the mark, fill it up to the mark, some Lazy dude they dont care they just fill it up and let you go, its not their car, its ur car you need to take care.

Thats why i hate it when Auto-Dealers state that "Lady Driven None Smoke" its not smoke inside the car but its smoked in the Engine/Trans, well i rather buy used car from Smoking Machanic guy than a Cleaned Car from a "Lady Driven" my friend got screwed Engine/Trans he bought a used car that "Lady Driven" its very clean but its screwed-up.

To me all lady driven means is oil never checked.
