IMS is coming home-rebuild time- Parts?
 

My LN rebuilt IMS is on its way home so its time to finalize a parts list.
2004 Boxster S 3.2L 40,000miles had an IMS failure.

In addition to Porsche gasket set repair kit, bolts, bearings, rings, thrust washers, chains, low temp thermostat, IMS - Crank paddle tensioner (LN) what else do I need?

Wondering about - other 2 tensioners and guide rails (they look to be ok)? What spark plugs? What coolant?

Considering - AOS how do I know if it needs to be replaced?, clutch repair kit complete - Porsche OEM (can I get away with just a clutch plate)?

Any suggestions?

I bought the platinum spark plugs from Pelican along with a new set of spark plug tubes and o-rings. For coolant, I bought OEM coolant form the local Porsche dealer. It was cheaper than Pelican. Surprisingly. Would have been even cheaper if I had of had my PCA card at the time. They just enterd my member number and poof - instant discount on parts and service. Best $45 a year I've ever spent.

For the clutch, I would not skimp. There is nothing worse than having to do the work twice because a used part failed or caused uneven wear and tear.

As for the other parts you may need, well to be honest until you tear it all down, and I mean all the way down, you have no idea what your IMS failure may have done. Some of the pictures I have seen are really bad. Some not so bad at all. If you didn't lose any major parts (no D chunk either) you may be OK. You'll still have a lot of ports to clean though and it'll take a lot of time, but if you can save it, do it.

After any failure the chances of trauma impacting other components is real. Approach with great care and remember that every component is guilty until proven innocent.

Having components surgically clean is a must after an IMSB failure and oil system contamination. Have the crankcase and carrier ultrasonically cleaned, otherwise you may never remove all the debris from them internally.
