Fire the car up quickly.. when the noise begins depress the clutch. If the noise goes away its in the gearbox, if it doesn't go away its in the engine.. Depressing the clutch stops the tranny internals. Pulling the tranny won't tell you much of anything. You'd be better off to pull the sump plate from the engine to inspect for debris and do the same with the filter. If you have something going south the debris will be there, take pics of that debris and I can tell you what it is, more than likely.

Your engine is low mileage and you should get a second opinion.

Its impossible to put a price tag on this, if its just a cylinder head/ related issue you may be able to get out of it for 4-5K. Nothing can be done internally with these engines for less than 3K.

I've heard lots of impending IMS failures, this doesn't fit that stereotype... I could be wrong, but the rythm of the noise sounds like something valvetrain related in the cylinder head. Remember, this engine has more than 20 different modes of failure that we've identified thus far, the IMS failure is just one of them.. Too many things are mis-diagnosed because the IMS failure is so widespread.

IF it is an IMS failure I could save the engine, more than likely but not if it continues to be driven..

Pull the serpentine belt, see if the noise goes away. Pull the sump plate and filter and look for debris. Post the pics.
