Turbo Whine

Does your Mitsubishi L300 make a strange noise? Need wheel alignment specs?

Turbo Whine

Check the bolt tightness on your exhaust outlet... maybe even for a hole. My new exhaust loosened off, and sounded like a 747 on takeoff. No carbon trail, no ticking sound, but tons of turbo noise. My old springs were fractured all over

Double checked all that. No noticeable holes or leaks in the pipes or joints. Ran my hand over it all with the engine idling and didn't feel any leakage.
Waiting for the new turbo to arrive and swap it out and see...perplexing as I'm still getting full boost. :?

I have a bit of a whine to my turbo which perplexed me until I took the beast apart. My heat shield doesn't seal properly due to lots of corrosion so it vibrates causing a distinct whine/rattle. I live with it.

I'll have a look at that when I swap in the new one. If it all looks ok I'll have a spare.
