Serious engine problem. please help

[loominaz34]

OK so I had the car running well for less that a week when a new problem arises.

 

The engine was making a small ticking sound at low RPM so I checked the oil. It was 1.5 Quarts low, thanks to the oil pump drive O-ring. I filled it up and, Thus satisfied, I kept driving. the ticking continued as I drove, anytime the revs were under 2000 or so. That was yesterday. No problems other than the ticking as far as I could see.

Today, I went to drive to work, first, the engine started extraordinarily hard. ticked like a cold diesel and was almost totally unresponsive to throttle. An inch of throttle movement got me to 3000 RPM in park, barely. I drove for about 4 minutes and the car was warmed up, a lot faster than normal. and the ticking was still increasing, not dispaearing until it was drowned out by the engine. I got back hom in another 4 minutes and the exhaust system, mainfolds to mufflers, is smoking and it smells like burnt oil.

What the fuck happened? Im sorry I am of no help on the forum and I apreciate all the answers I get here. sorry if I seem like a nag

what kind of problems were u having before? if any maybe a thrown rod? hows the oil pressure?

[White93z34]

sounds bad...can you get us a recording of the noise?

moving to powertrain

My dad's Suburban with 6.5turbo diesel was running like that, while driving it in for service , a piston which had cracked exploded and sent the rod through the bottom of the block, punching a whole into the oil pan....I saw the old engine after it was removed, whole bottom end was blown off.

 

I'd stop driving it if anything.

I don't have an oil pressure gauge but I'm going to see if a new oil filter will help. (i'll be driving my mom's car to autozone.) I can't get a recording of the noise but it's a dead ringer for a cold bus (diesel) from inside the car, ticking's kind of a weak word, it's more like a knock. It seems to be coming from the back/ left side of the engine only but I could be wrong.

Prior problems were a bac ICM and the timing belt was set wrong. For about a week it ran beautiful. this started suddenly yesterday.

try spme marvel mircale oil maybe a stuck valve

[loominaz34]

Sound is coming from more than one thing, It's transformed from a steady knock into a sound similar, Id imagine to about 5 nuts in a paintcan mixer without driving the car. I, maybe conveniently, forgot to mention that I had been showing off how well the car was running when this started if you get my drift... wish I hadn't now. O yea, car has 180,092 miles on it

 

EDIT: I also noticed that in the maybe 1 mile i traveled, I lost about 1/2 to 3/4 quart of oil.

sounds like its about to take a shit sorry to hear

[1990lumina]

Does it sound like this??

[White93z34]

start shoping for a new engine / car.

[loominaz34]

1990 lumina, It sounds like that but it's happening on at least three cylinders, it sounds HORRIBLE

[1990lumina]

I see.....I was just trying to help with diagnosing the sound.....my car has been like forever and still runs fine (other then it's annoying as hell)

[Ned Flanders]

I remember when my 89 Regal threw a rod in a main intersection.

Those were the days.

[19902drlumina]

yea start looking for an engine or do a rebuild

[JoroCorona]

Thats the exact same thing my lumina did after I changed the timing belt. Its the rod bearings.

[loominaz34]

I was poking around and found my oil filter to be LOOSE (forgot to mention this earlier I was tired) which is probable the cause of the smoking exhaust pipes and the burning oil smell. What would oil starvation effect first?/ what would make my car sound like a Cummins?

Yep

[loominaz34]

Cool, so thus proven, I'm a moron. What did I most likely break?

well im sure theres some extreme wear but it might have some miles left on it, prolly severly hurt the bearings and what not

[DaveFromColorado]

that knocking sounds like 1 of 7 things I've seen GM's do...

 

First, shelled out lifter (doesn't offer any pressure anymore)

second, rod knock from a spun bearing

third, the rubber mount on the vibe dampener broke.

Fourth, the flywheel/flexplate is cracked

Fifth, Piston slap (piston or bore gets too warn and the piston rocks 'round in the cylinder)

Sixth, timing chain slapping the cover

Seventh, The timing chain skipped a tooth and you're tagging your valves, which would account for the extreme heat off the exhaust and built up all throughout the engine, this would not only retard the ignition timing, but valve, and injector timing as well causing the lack of power.

 

I'd guess your timing chain went and jumped a tooth on ya ...

If it still has the ticking coming from the back of the engine it is a bent lifter my cutty has the ticking it is annoying as hell i was told if it bends more it will sound like a deisel but i can be wrong

[loominaz34]

thats about the same thing my autotech teacher said. I'm going to check my timing first and see if that's the problem, if it's not, I guess I'm pulling the carriers. This weekend is gonna be fun!

[DaveFromColorado]

I need to correct myself.. I said chain where as I meant to say Belt ... my bad! I've never seen the timing chains skip a tooth (they slap the timing cover a whole ton, but never enough to jump a tooth!) but I've seen pleanty of belts skip one or two teeth.

[loominaz34]

belt is good. I just replaced it. but before it was off a tooth on the intermediate pulley and it ran like shit. now it idles normal, just make a lot of noise.
