Ran NEW engine out of Oil!!!

I have a new Japser engine in my blazer 4.3 liter. From new I put Mobil 1 extended life. Before I new it I had 15k miles with the same oil. I do not check oil levels. Well one day I heard it pinging on the top end, like the oil was running low. Well it was 3 quarts low!!! eek!!

I added more mobil 1 and the loud pinging will not go away. I ran it about another 3k miles and it is running good, same gas milage, but the top end is still pinging awefully loud.

What do I have to do to fix the sound. Is the engine dying? Will Japser's 75k mile warrentee cover it? Am I SOL?

OMG! 8] Please tell me that you changed the oil at least once before you went FIFTEEN THOUSAND MILES!

If not, I seriously doubt they will cover that under warranty.

You probably damaged the lifters. Not sure about the cam shaft. But youll definitely need to tear off the top end to totally assess the damage. Get a bore scope also and look at the cylinder walls for damage.
I would suggest taking off the oil pan and checking the bottom end but with oil at the bottom you might be ok. Also cause its like a two day job to R&R the oil pan on my 4x4.

Good luck and please post any further discoveries. Pic's are great to.

(Hey I just noticed, this is my second year :) yay)

The mobil 1 was suppose to be good for.... well a lot of miles. Probably not 15k. :banghead:

How difficult is it to ripe the top end appart to assess the damage and fix the lifter?

Its not so much the number of miles as much as it being the first oil that was put in a new motor.

There are a lot of particules that accumulate in a new engine. Therefore it is suggested that the oil get changed soon after you start using it. I like to say around 100 to 500 miles myself. Some others say 1000.

As far as tearing things apart, I would suggest getting a Chiltons or Haynes manual. Youll have to remove the intake and valve covers I think. Im just guessing here. There are a number of things that could be damaged.

Im pretty sure you could get to most everything on the top end with the heads still on. Not the valves of course, but I think those would be ok.

Before You rip anything apart, do an engine crank case flush. My 2000 Jimmy started doing the same thing out of the clear blue with regular oil changes and nothing running low.

I used the Gunk brand 5 Minute flush. Here is the basic method that I used. Drain all of your existing oil out and remove the filter. Buy the cheapest regular 5w-30 oil on the shelf along with the cheapest filter they got. $1.00 per bottle stuff is fine. Add the cheap oil, the Gunk Brand Flush and the cheap filter and run for 15 - 30 minutes. **Caution, When you have the Flush in the engine, IDLE ONLY I repeat, IDLE ONLY.**
(The Bottle says 5 minutes, so let your conscience be your guide). After flushing the engine, drain the cheap oil and remove the cheap filter and install your best filter and new Synthetic oil. My very loud lifter knock went away and never came back. The flush, cheap oil and filter cost me under $10 USD.

For anyone that would like to try this..... when he says "run" for 15 - 30 minutes, he means "idle". Anything above an idle while flushing the engine will most likely result in engine damage.

Mobil1 is a very good oil. The extended life claims to be good for 15,000 miles, but it is still recommended to change the filter at regular intervals. 15,000 is probably more than Jasper allows one to go that is under warranty. The last time that I checked, the extended life still didn't have the approved seal that most manufacturers require for warranty purposes. Regardless of how good an oil is, no oil will provide adequate protection when 3 quarts low. The only way that I see Jasper covering this is if they don't know what really happened. You've basically given them three good reasons not to warranty it.

Thanks Blazee, I'll edit my post.

if youre going to spend the money for a new motor, id think you'de be smart enough to change your oil EVERY 3K miles AND check your oil regularly. I think you're shit out of luck. Is there a warrantee on your motor?

Is there a warrantee on your motor?Changing it at 3,000 is a waste of oil. That's why most manufacturers now recommend 5,000 or more.

Just an aside - not sure about Jasper (if they break the engines in for you), but I thought synthetic oil wasn't recommended for the initial 1000 miles or so of break in? Maybe I'm misinformed.

I don't believe that High Mileage oil is synthetic. I might be wrong thougt, since I've never used it.

One things for certian, if your motor is still good it's well broken in
