Hoping Engine isn't Blown...

**swimster144** · 01-10-2007, 08:45 PM

So I was out driving tonight, and playin' around. I mis-shifted and I think the engine RPM went pretty high, but I'm not sure how high since it all happened so fast. But, the weird thing is, it jerked my car rapidly really bad and killed the engine. Went to start the engine back up but no go. Pulled it over to a safe spot and tried again, no go...finally it started up, but barely, and idled REALLY roughly, sounding almost like it was misfiring or running out of gas or something. It was also shaking the car kinda bad as well as the shifter. Then it would die after a few seconds...

So, I've mis-shifted before and accidentally sent the RPM's up, but it never hurt anything nor did it kill my engine. I have no idea what could be wrong. I'll have it towed to a shop tomorrow, but does anyone have any idea what it MIGHT be??? It is a 1999 Camaro Z28 (LS1) with a 6 speed manual.

check the plugs, sounds weird but worth a try.

any noises?

**swimster144** · 01-10-2007, 08:59 PM

I checked the plugs and the wires, they all seemed normal from just a visual check. No weird sounds or anything or the sort aside from it just idling like shit and then dying.

were you low on gas? or out?

you should take the plugs out one at a time to check them.

**swimster144** · 01-10-2007, 09:13 PM

well I had a little more than 1/4 tank left when it happened... I'll have it towed tomorrow to a shop and we'll see what they say. I've tried doing plugs before and they are a bitch to even get at, so I bagged it.

I am wondering if my rev limiter kicked in and cut the fuel right as I put the clutch in and something happened to the fuel pump. That would explain why it jerked REALLY badly when I tried to let the clutch back out, being in gear with the engine basically off. Is that possible?

+1 to the fuel pump

Also might have bent or broke some pushrods. Stock rods are known to do this when hitting the rev limiter hard.

I'm guessing bent pushrod (s).

Probably floated a valve. From there you could have busted a valve spring or a valve itself. If a busted off piece got into the cylinder...you bent a push rod or have a hole in a piston. No biggie...part of hot rodding man....

thx for all the input guys, we'll see what happens, i'll let you all know.

**swimster144** · 01-12-2007, 01:28 PM

Ok, so basically, its either a blown cylinder head on the driver side of the engine, or just a blown engine... I'm going to be selling the car anyways, but what do you guys think is best? Should I first drop a brand new LS1 in it, and then sell it? Or should i sell it as is, for around $4,000 - $5000?

O and BTW, the car (chassis and all) only has 66,000 miles on it, and it has an upgraded sound system in it with Pioneer Deck, and Polk speakers, and would also come with a few SLP performance parts (SLP MAF, SLP Airlid), straight pipe exhaust setup and K&N filter...

**swimster144** · 01-27-2007, 10:27 PM

So basically I ended up putting a whole new LS1 into it cause I wasn't sure what was wrong the engine and I didn't want to risk replacing part of it to find out the bottom end was toast. So now the car is practically new condition and drives like its new. It's awesome...too bad I have to sell it cause I can't afford to keep it and I really need a 4X4 to get me around a little better in the snow for the time being. Check out the thread I am selling it on if any of you are interested. Thanks.
