My Car:
2005GT - 6SPD.
Updated flash.
110,000 Miles.
Original Engine.
Royal Purple 5W-30.
New Coils and Plugs@ 108,000 miles, 2nd Optima battery.

Problems:
From 103,000 Miles to current, car burn 1quart of oil for every 1/4 tank of gas!!! Low oil pressure light keep popping up hear and there. Keep topping up oil.
***If the car is running, from 1st to 6th and from 2500RPM to 9000RPM in every gear, no loss of power, as far as I can feel. I have not have an actual compression test yet.

Thursday 10/29: The car started to have a hard time starting up.

Friday 10/30: It will take at least 30sec for the car to start.

Saturday 10/31: check the dip stick, see oil level is low. The car have to crank at least 4 to 5 time for it to start. Let the car warm up drove to autozone, purchased 4 quart of Royal purple 5W-30 fill up 1.7quart of oil. Start the car, the car will not start. For more than half an hour, even ask the autozone guy to test the charging system and battery- every seem fine according to test equipment. Finally the car started. Get on the freeway, for 10mins, 5th gear, 75mph, the car seem to run find. Traffic slow down, after traffic back up to speed, I shift to 3rd and accalerated to 9k RPM. Look rear view mirror, see a trail of smoke behind my car. slowly pulling over and notice lots of smoke coming out of engine bay. All gauges indicated car is not overheat, car does not loose any power just lots of smoke. Pulling into gas station, pop up the hood and find the engine compartment is cover full of oil.***did not turn off the car because i am afraid it will not start backup again. drive home slowly. get to the house, park the car, kill the ignition, later come back out try to start the car backup and until to day, Tuesday 11/3, the car will not start. Check engine light do come on with code P1688. try to zero out the omp. Get the car to start again, take it out to street, step on it got smoke, engine compartment is full of oil again.

I am tried to describe as much as to what happen to my car, please, if anyone who had this problem or know how to fix this issue, please help me, tell me what i need to do to resolved this problem.

Thanks
Ben

That's a new one (from what I've seen..)

Going to keep an eye out here.. Maybe an oil line is cracked/ruptured, the filter wasn't secured properly, ehh no idea..

Loose oil pressure sending unit? Hoss-05 had that problem and it was spraying everywhere. Easy fix.

If the oil is ending up on the exhaust manifold the OMP area is a good place to start.

Best thing to do is to clean things up and then run it if you can to see where the oil is coming from...makes it a lot easier to diagnose

There are a lot of potential spots...the oil line attachment points to the engine...the OMP, the OMP lines, the front/rear seals...etc....

Side note - stop driving the car. It sounds like you have a massive oil leak and probably cannot hold adequate oil pressure. Running a car with no oil pressure is generally not a good idea. Losing that amount of oil, you would think it would almost have to be trickling down from the engine if you idle in place.

9KRPMRX8,

Would you mind tell me what the fix is? Also, I have search and try to read as much previous posts as possible and found couple of post say that the OMP suppose to drip oil into the rotor not inject, therefore if the line rupture, would it just leak rather than spraying oil everywhere???

benh

The car is park in the drive way. I read on one of the post and someone suggested to adjust the OMP sensor seen it might have open too much therefore excessively pumping oil into the rotor which cause flooding. after i did some adjustment (Rezero) I try it out for a drive around the block and the oil spray happen again.

WHERE IS THE OIL COMING FROM

Sorry...but you need to figure that out FIRST.....

benh

I will try! The problem is when the car is on idle, it doesn't seem much oil leak. The oil spray is when the car is at high RPM. I will definitely try to hunt it down. I will let anyone who might interested in this issue know what the cause is when i find out.

Put cardboard down under the car and rev the engine.
Also check the lines that go to the oil coolers. I have half the miles you do and I have had replace one of them due to corrosion. But then, I don't live in sunny SoCal either.

LMAO you said it before I could STOP DRIVING THE CAR.... find the oil leak and fix it....



but seriously dude it sounds like a simple leak somewhere OMP, sending unit, oil cooler line...

If you drive with no oil pressure or with a really bad leak you can spin a bearing and destroy your motor.

Well, it took us a bit to figure where it was coming (it was everywhere) from on Hoss-05's car. The pressure sending unit is above the trailing plug on the rear of the block.

As others have mentioned above, you really need to clean up all the oil that is on the engine and components.
Then start the car and inspect for leaks.
Have someone in the car revving it while you're under there looking too.
You may not see it right away, so run it for a few minutes and see if an oil trail forms somewhere.

Check around the OMP too.
There is a copper gasket where the four clear lines come out of the OMP through a banjo fitting.
Also check behind the e-shaft pulley. I've seen it leak there from a bad front oil seal.

Not to tangent here- but I though synthetic oil was not supposed to be used in these since it doesn't burn as cleanly as normal oil?

Oh Really?

Ericok

Low oil pressure is the least of your problems. With a leak like that, you could be easily be looking at an engine fire.

Nubo

Maybe you missed the 1100-reply "Sticky" thread on that subject

I guess he really likes Royal Purple, to feed it 4 quarts per tank of gas!!

*Sigh* ...

9K ... you got him right ? ... yeah you did ...

I just gonna go away ...

You can if you wish purchase an Oil Dye additive, add to engine oil , start car, and use a "Black' UV light to find oil leak trace.

I don't know how good this UV dye is...worth a try, or clean down engine as other have suggested to find the leak...

dannobre

It works OK....I found a front seal leak with it that I couldn't pin down

Usually you can find it without all the dye and fooling around if you clean it up and watch where the oil comes from

Is that synthe-renesis oil real? I see it's in japanese but I've never seen that advertisement here before....just my curious mind acting up again...

to the OP like everyone else said you need to find where it's coming from before you can fix the problem...
