^+1, also what do you know of the car's maintenance history? Changing the motor oil too infrequently can clog up the tensioners and eat up the guides...

Yes this is true! A lot of people think it's ok to use 10w 30 on these engines. It is never good to go past 5w20 on a mod motor so if you have or in the past it could of clogged the tensioners and you might have a loose timing chain. Pop the valve covers off first check to see if the cam bolts aren't loose ( do this by hand it's a common problem ) then see if the chain is dangling. Does your engine sound like a diesel at all?

I bought the car with 70K miles and the guy before me put 5w30 in the oil for the past few changes. Is that bad???

No. I run 10W-40 here in NE Florida in all our vehicles, my '03 GT has lived on it for 6+ years and 135k miles--changed every 2500 to 3000 miles. I do buy the 5W-20 thing and would not run it in a lawnmower here in Florida--but that's another discussion.
Which brings us 'round to the most important thing, which is how often was it changed?
In any event you will need to pull the cam covers as jjsg09 suggested--and "see what you can see"...

I'll post a video of what it sounded like after I changed the plugs.

Here is some good videos to see. Your car should not be having issues with timing at that many miles. These engines have those problems at higher miles. But good to check now before disaster. It's making me want to tear into mine next weekend to be on the safe side LOL!

I agree that at 76k miles it shouldn't have timing chain problems--doesn't mean it can't however. Very poor maintenance cold make it so. For example my son-in-law buys a new car for his business each year, and changes the engine oil maybe 2 or 3 times over 50k to 60k miles.
He is not the sort to change oil himself so he views it as unnecessary expense--his feeling being since he will not be driving it after two years it doesn't matter. God help the poor slob that buys it next...

Sounds like a wasteful individual. Not to sound rude. I one time had the pleasure of a customer that had bought a 1996 aerostar new and had changed the oil Once a year. That was in 2000. He wondered why he wasn't getting any oil pressure. Well the pan was full of gelatinous sludge. Yeah that Nice four year old car with a voided warranty and a bad engine. bummer.

That's fine, I thought he was an arrogant àsshole the first time we met--that has not changed. He's an "entrepreneurial" hustler that lives of money conned from investors silly enough to swallow whatever snake oil he's peddling this week.
Here's a video of an '04 GT that had been so abused...
