Gas Engine

Why has my gas engine started sounding like a diesel engine?

When idling in drive and reverse, my gas engine has started sounding like an idling diesel engine. It sounds like a normal gas engine while in park and while actually driving.

A few months ago the manifold cracked and coolant got into the engine. A few days after I got it back from the mechanic, one of the lifters got stuck, but that was repaired quickly.

Could this diesel sound in idle have anything to do with either/both of those events? Is it something that needs major/immediate attention?

HI
How well do you trust that shop??
Which manifold was cracked? It would have to have been the intake manifold..and only a replacement would fix that. Unless it was the intake gasket.
A stuck lifter is not usually an quick repair.. could include a partly tare down.. Now an exhaust manifold leak can sound like a stuck lifter and make it sound like a diesel as well at idle.
I'd maybe get a second opinion.
Good luck
