Chain Tensioner Replacement Clarification

[Need_for_speed]

Just emailed flat six innovations on this topic, and they seemed to think that the engine was toast because of the .5 second rattle when it starts up. They quoted me $18,000 for a new one.

Wow. Really?! Gosh, I guess I'll be needing a new engine as well!

My 2.7L is getting a new IMS/Clutch/RMS shortly and my Indie says he here's a slight rattle on startup for a few seconds. He attributes it to the chain tensioners/ramps, or, more likely, worn out plastic camshaft brakes (Pelican Parts -- $19.95 for the set).

At 70k miles, my '02 986S has a little rattle on startup after a couple of seconds...perhaps 1sec worth. Best independent Porsche shop in the region did the IMS/RMS and it's unchanged thereafter. They didn't seem concerned about it.
