Here's some areas I've replaced leaky seals: Oil pump, cam seal, crank seal, rear main seal, valve cover seal, and valve seals. Thing is, most of those you can trace to the leaky source so if you can't I would imagine it's burning oil internally...but you said no blue smoke so that's kind of weird.

Valve seals will blow blue smoke too but usually just at start up.

Also when you say barely a quart of oil in the engine when ready for an oil change, do you mean there's barely any on the dipstick? If that's the case, that's only about a quart worth of loss. If your engine didn't have any oil in it, it would surely die in minutes while running.

No, not dipstick. i change my oil every 3000 miles. when i drain the oil pan there's little bit of oil.i feel its a little less then a quart. When oil is just changed car is smooth. As it gets closer to oil change it sounds like its gasping for air when accelerating in 3rd/4th gear. All in all I am just going to change the rings and monitor the oil consumption.

have the head checked, the valve guides could be worn and you may be sucking air and oil past them causing it to run lean. Also the upstream O2 sensor is probably fouled out, and the intake manifold likely filled with **** from years of blow by.

Yeah do the piston ring soak. Pull all four sparkplugs. Pour about an ounce of Seafoam or Marvel Mystery Oil down each sparkplug tube. Let the car sit for an hour and then turn the engine over(Might want to toss a rag over the sparkplugs, the cleaner may spray out). Now let is sit for maybe 6 hours. Next, repeat with another ounce per cylinder until the bottle of cleaner is gone.
You may have to clean the oil afterwards or wait a couple hundred miles , all that MMO or Seafoam will be in the oil now.



I changed the engine on my 94GT for <$300. A rebuilt engine from the salvage yard only cost me $200, I just got lucky and found one that wasnt even broken in

Hello all: I recently bought a clean ST. 1996 and is in the process of getting it fixed to my liking. Thus far I have done the following to the engine:

Timing Belt/seals (on that side) and water pump replaced
Axle replaced (boot leaked)
Valve cover gas kit replaced, plugs seals replaced
Plugs changed air/oil filter changed

This weekend I will changed the oil and fuel filter (part of tuneup)

Issue: The car is using oil. I drove it a roundtrip of 340 miles and it used about oil. the oil was one-forth low on the dip stick.

Can somebody educate me what steps I need to take to find the actual cause of excessive oil consumption whether it is valve seals or piston rings:

thank you.

next time please dont bump on old thread that has nothing to do with your situation.

as for your engine burning oil. It could be a number of problems. the only way to find the real problem is to tear it down and find it. I suggest a full rebuild since you are going that far.

Sorry but I have the exact same problem as the OP so I thought instead of creating a new thread I should continue with this one.

Sorry for the inconvenience
