993 Turbo; boost and ticking noise

[TTSam]

I just has some serious work done at my local dealer and changed out many parts:

Alternator Fan Belt - Outer With Tiptronic*
Alternator Fan Belt - Inner 10x757*
OIL PUMP*
**6 Pistons & 6 Cylinder
*FUEL INJ LINE*
*Head Gasket Set*
Porsche Valve Adjusting Screw
1 * *Rod Bearing Set (Standard) * * **
1 * *Main Bearing Set (Standard) * * **
1 * *Piston Ring Set * * * * **
12 * *Connecting Rod Bolts * * **
12 * *Connecting Rod Nuts * * **

9 * *Flywheel Bolts * * * * *
6 * *Valve Guides (Exhaust) * * **
6 * *Valve Guides (Intake) * * **
1 * *Chain Rail - Right Straight * * **
1 * *Chain Rail - Left Straight * * **
2 * *Chain Rail - Curved * * * * *
1 * *Case Gasket Set (Lower) * * **
1 * *Head Gasket Set (Upper) * * **
2 * *Timing Chains - Endless * * **
2 * *Intermediate Shaft Bearings - Large * *
2 * *Intermediate Shaft Bearings - Small *

That was the good news!

The bad news is my car now has 2 problems:

The turbo boost reads either .3 or .8, and even at idle it stays at .8

There is a clicking noise that is continuous. I have isolated the source to the lower left side of the engine. I'm a novice, but the speed of clicking sounds like the timing chain. I can feel tapping when I touch the bodywork in the engine bay left side.

My dealer said all these issues will sort themselves out after the break-in miles are completed.

Any insights are very appreciated

Looks like an engine rebuild? Correct? If so I shudder to think of the cost at doing this at the dealership.

Noise from a timing chain will not go away...it is either there or not.

The best board to get feedback on 993 Twin Turbos is:

(under the 993 Turbo Section)

This board is more geared the the pre-89 non turbo cars.
