i was driving the car yesterday and was having a little fun. was driving it a little aggressive, didnt go over 6500 RPM. it missed a couple times and went rich. parked it and looked at the engine, looked fine. went to start it and had the feared subaru sound. so now it is just sitting there.

my question is, if i pull the valve cover and take out the rocker or lash adjuster(whichever broke/fell off) and pull the plug on the injector, would it be ok to drive it a mile on 3 cylinders?

might be a stupid question but where it is parked i cant really work on it or have it sit for an extended amount of time.

 

Im curious to hows this sound?? Not for entertainment purpose, just curious

 

pretty similar to this....My supercharged cobalt with cylinder 3 piston ring out - YouTube

 

O wow very noticable.

 

Lol. "Subaru Noise" Right at the end. lmao

 

when he first goes to the exhaust and it sounds really lumpy is what mine sounds like....

 

if it isent blowing the dipstick out it may just need a set of plugs

 

really? that would be amazing! so if it drops a cylinder because of breaking a rocker or lash adjuster it will make the dipstick pop out?

 

this happened to me. just blew a plug

 

If it's only a mile it will be ok like that. Just baby it.

 

my sunfire made the same sound and i ended up changing the engine not knowing what was wrong, heres what it sounded like to give everyone a better idea

When you say blew a plug do you mean the plug blew out as in striped the head and shoot out? Or just that you need a new one?

 

have you done a compression or a leakdown test yet? is the dipstick popping out? how do you know you broke a follower or had one kicked out i broken follower wont make the dipstick pop but a broken ringland will if you are not having a stick popping problem try replacing the plugs it could be that its tie for a new set

 

also when this happened i didnt get any codes at all. no missfire codes or anything.

 

rockers an lifters

 

When that happened to my Civic, it was a cracked ringland..

Is there blowby coming from the valve cover/oil filler when u open it?

 

search me on youtube...xtremeranger95 I had that sound and it was a blown ringland....like woah bad....diamond pistons too!

 

looks like you had a detonation problem or an over fueling problem

 

yours is really quiet. whatever happened made my exhaust about twice as loud

 

I'd pull the plugs, could have an electrode burnt off/broke off.

 

i plan on doing this tomorrow. i will pull the plugs out and the valve cover off and check everything really good.

 

put a set of plugs in first before you pull anything

 

Update:

Went out there and pulled the valve cover off and looked in. There were no rockers or lash adjusters off or broken. Had me worried that it was a piston now. Did a compression test and here are the results 1-4,

1- 198
2-200
3-190
4-195

Now I know you are supposed to do this with a warm engine. Mine was cold. How much of an effect on the numbers would this cause?

I also let the pressure sit there on each cylinder a little bit to see if they dropped and none of them did.

Also, the plugs that I pulled out looked ok I will post pics of them later.

So after all the I figured I would put her back together with new spark plugs gapped to .034. Got everything together and she started right up and ran completely normal!! Idk if a coil was loose or what but no more Subaru sound!!!!

 

Was your electrode fucked on the spark plug? As i said above, that's what had happened to me and i just replaced the plugs

 

They all looked fine. I will take pics of them later and post them up.
