Hi all, just picked up my first Toyota, a 2000 Land Cruiser. Test drove it when already warm in a louder area, and couldn’t hear a ticking sound while the car was hot and in park. But now I realize when the car is cold there’s a loud ticking coming from the exhaust manifold, yes I know the implications of this job, but it really is only loud when in drive. And it stays even in drive after the car is warm, granted it’s a good bit quieter. But here’s the thing, when in drive sitting still it ticks, but in park it doesn’t. Is this normal for the exhaust leak? I’m about to take the car on a 2 hour roadtrip to college, so I’d love some help. Thank you guys for all the assistance.
