Blown Or No?
Nope not my car...
A friend of mine bought a 94 SSE for $150. The guy he bought it from said the engine was blown. I went out to his house today and we got a battery hooked up to it and turned it over, and it stared right up. But there is a weird "clanking" noise. Its not a steady noise it happens intermittently, but "steady" if that makes any sense at all. :P
It runs but it doesn't sound healthy.
Is that something you guys have run into before? Is it blown or is it something that could be fixed.
We checked the valve springs, because his dad said it sounded like it was a busted valve spring, but they are all fine. His dad (a mechanic at a Pontiac GMC dealer) said it sounded like some balancing rod or something (can't remember the exact words he called it.)

Just a guess but maybe a busted connecting rod or bad rod bearings, causing the piston arms to slop on the crank.
If you can't find the noise soon, jack the car crawl under and listen near the oil pan if its loud, then I would drop the pan and have a look.
Just a guess,

Well thanks for the help guys... but after trying to work on it a little he started it up again, and we heard a loud clunk and lots of smoke, and looked under neath and found pieces to a piston rod laying on the ground so, yea its blown.
