Did I just kill the engine? :(

[EgonOlsen]

So ive been trying to get the car ready for summer, atm. just trying to fix my idle surge.

All of a sudden the other day the engine started to say funny when I had it started to check the surging.
Did it just break inside? I attacked a short vid of the sound. I know its hard to say something for sure, but any help would be nice.

Please say its something cheap.
Could it be a broken waterpump for instance?

I know what it is not...water pump.

Yikes. Well positive side is that it still actually runs. Negative side is that it's god awful sounding. When I spun my first motor it sounded like that.
But the motor would come to a halt after about 5 seconds.


-- pull off the oil pan, see what you find. Make you you didn't drop anything down in the timing area since you don't have the cover. I found a rock in mine.

 

[EgonOlsen]

I pulled the oil. it was all greyish.
I took of the oilcap and it was filled with yellow goo.
Took the watercap off and I think some water started running out of the oilplug.

So a blown headgasket leading to some kinda overheating(oiltemp never went above the ½way mark) leading to a sprung rod bearing?
That sounds like loads of bad luck to me. <img src="/ubbthreads/images/graemlins/frown.gif" alt="" />

Well as long as to have the $$$... It's a positive thing! Rebuilds are awesome times!

 

[EgonOlsen]

If you live in US maybe, overhere its pretty much something only done to extreemely expensive engines. unless you can do it yourself, which I cant.
I dont recall anyone overhere ever doing a rebuild(if you need a machineshop and stuff)

often its cheaper to get another engine, but ill look into it, f*** it all to hell, pardon my french.

You can drop the oil pan with the engine still in the car. With a dental mirror you can try to inspect the rod bearings and see if one of them is spun. If it is then the whole motor will have to be pulled to clean the debris out. But, if the cylinder walls aren't beat to sh*t you can reuse the pistons and you don't have to machine the block. But you will have to replace the crank and at least the one connecting rod that spun. At that point you may as well do a full rebuild or just buy a JDM engine.

 

[EgonOlsen]

Yeah I just mailed around to see what I have to pay for a JDM engine.

Prolly easiest just to pull the engine out. I can fix the whole bay up nice also then.

Just a little sad I have not driven it at all yet and I was about to get ready for my first drive. then this and now a drive is miles away. /ubbthreads/images/graemlins/frown.gif

Overheating did not trash the bearing(s), water did. Water is NOT a good engine lubricant...

 

that doesnt sound like rod knock. kinda sounds like a few minor bent valves or a rocker going crazy. possibly even comming from the trans. do a comp check, check your timing and go from there.

 

[turbowop]

Don't the hydraulic tensioners make some kind of weird racket when they fail?

 

yeah but it doesn't sound like that.. it just seems to run too smooth to get rod knock and have it be that loud. sounds kinda like broken trans or something. broken clutch plate?

 

[EgonOlsen]

would a blown headgasket and a blown clutch at the same time be a kinda stretch?
This happened while idling btw.

We kinda know the headgasket is blown because of all the water in the engine right?
so the noise would kinda be a follow up on that right?

 

[belize1334]

Did you overtorque the oil-cooler? That can cause water to mix with your oil.

 

[The_Big_Weave]

Oil in the coolant, if not taken care of can spin a rod bearing because the oil becomes to thin.

 

[4thStroke]

The consistency of the knock does not sound like a spun bearing. If it were spun, it should knock every time that bearing makes a revolution, which it is not doing. The noise doesnt sound like a spun bearing, either. I can't think of a reason for a motor to blow a head gasket at idle and normal operating temperatures if the motor was healthy to begin with.

 

[Struc]

Balance shaft bearing went south and the balance shaft is rattling around?

Did you do a compression check? Pull the valve cover?

 

[Vman911]

With it running you can dis-able each cylinder 1 at a time and see if the noise goes away when the plug wire is removed.
