Ticking at idle in 987.1 Boxster S with ~113k miles
Thursday 02/12/2026 | 2005 | Boxster S | Engine
My car ticks at idle. If I give it just enough gas to get above 850 - 900 RPM, the ticking sound goes away. I don't find that I'm burning oil, I've had the lifters and clutch replaced, and the car otherwise seems to run strong. I had an engine oil analysis done (I don't know who the mechanic sent it to though) and they said there was no metal in the oil (did they test for aluminum? I don't know). Any thoughts on what could be causing the ticking? Thanks, Da ...

I purchased a 2004 Boxter S with a damaged immobilizer. But the previous owner lost the damaged immobilizer so I don't have the chip from it. A Porsche parts shop has a set ECU, DME, immobilizer and key from a 996.2 C4 and wondering if this will work? The ECU has the same numbers on both the Boxter and 996.
