87 3sge engine knocking

**panish** · 03-16-2006, 08:18 PM

So here's the scoop, put a new muffler on my car. (yes, a cheap fartcan) It ran fine for a few days with the silencer in. (It's plenty loud) I take the silencer out and it runs for I'd say 6-10 miles, before the engine messes up badly. I noticed while accelerating quickly right before it [died] that it seemed to have much less power than normal, let off the gas put the clutch in and it stalls. Starts up fine but can not hold an idle, its idling way too low, and stalls. So I drive off, trying not to let it get down to idle at all, and notice that there is a loud tapping or knocking noise with the engine. It seemed to be louder when the gears were engaged. I was only about a mile from my house so I drove it home, accelerating and putting it in gear only when I had to. I have not driven it since then. (Tuesday March 14) so basically the engine is out of whack. It makes a very loud knocking pretty much anywhere over 1500 rpm. And when you first start it, it will idle at 2000, which is normal, and the knocking wont start for several seconds then it comes in, and sounds just awful. I have a video, It is really messed up, the thumping noise is nto really there, I gues my camera is messed up too, but I think you will be able to get the idea from the video.

also, I put the silencer in soon afterwards so the engine was still warm and it can hold idle, so this problem seems to have something to do with back pressure.

Oil was changed in december I checked it and it was fine, however, the oil gauge does go down to low on idle, but I think thats normal.

as long as there is some oil pressure, and oil in it than that's fine...
hm...I'm scooped for an answer, sry.

Hey Mike...do I sense you are a bit of an opportunist??

**Locker** · 03-17-2006, 01:42 AM

now what would make you say that

**panish** · 03-20-2006, 04:37 PM

Holy crap everyone read this: Mechanic says its out of oil! oil gauge was the same way it has been since dec 05, it has been driven less than 500 miles, it doesnt have a visible leak. I checked the oil after the incedent and it was at least around medium, I dont know I didnt really do it properly. All i have to say is: WHAT THE HELL?!?!?! Looks like ill be buyng a new engine though...damn

**Locker** · 03-20-2006, 05:00 PM

If your in the toronto area I've found a bunch of importers selling the 3sge at decent prices
