My truck seems to be using an awful amount of oil lately. As long as it's sitting still, it's ok, but leaks when hot. I know it burns some, but not nearly a quart in 400-500 miles. It's a stock 5.7L Vortec V8 with about 200K using 20W-50 motor oil. Any thoughts?
a quart every 400-500 miles isn't alot. My bronco used to leak a quart every 30 miles. Could be burning that.
The **** isn't just disappearing. Your hoopty be burnin it up!
at least his wiring harness isn't held together by 150 red butt connectorsQuote:

There are only 58 and every inch of your bronco is worse.Quote:

aw ****. theres a sterling and a sparling? wtf?!
damnit i didnt realize which one i was talking **** to.
200k is quite a bit of miles on that motor, sounds like bad valve seals and worn out rings, does it smoke at startup?
200k and its using that much oil?
I'd start by checking the front main seal, rear main seal, oil pan seal, valve cover seal, all the valve seals, timing chain cover gasket, oil cooler lines, valve cover gaskets, intake manifold seals, compression check, find the title, buy an autotrader, eat mexican food, pick out a newer truck while pooping
It's probably easier to keep it topped off than to fix the problem unless it's something like the valve cover gaskets. Try lots of seafoam through a vacuum line, I'm sure that'll let you know what a bad oil leak is.
Are you sure it's leaking, not burning? If so, I'd say it's something that only sees oil when the engine is running, like the valve cover seals.
It doesn't really smoke on start-up... maybe slightly in cold weather. It really wouldn't bug me if it gradually increased consumption... but it was more like all of a sudden it started drinkin it.
Maybe it's leaking into your transmission. You should pull both out of the truck and seperate them to check the seal between the motor and transmission and make sure nothing is leaking back into the oil pan.
Pull both? Wtf? It has a 1 piece rear main. So at worst pull the transQuote:

I'm just sayin, that sounds like something you would do...

Then I'd move it into my garage to collect dust and trip over when adjusting my sprinkler system's timer.Quote:
