If you haven't checked the Durametric site in a while ,I recommend it. The latest version for my 2001 Boxster S is 184.108.40.206. My previous update from 2017 was 220.127.116.11. Who knows what has changed/improved. It still seems the same to me but faster and more consistent.So thank you Durametric !
It is also possible to accidentally muddle adjacent connectors because the cable is long enough to connect to the wrong plug.
He also has a useful SAI diagnosis video. His video was made without referral to some of the Boxster/996 sites ,so he misses a few tricks but it is a better tutrial than any other I have seen.
Carbon on #1 piston - is it too late for a leakdown test ? Oval/taper is a theoretical cause?
I found M5 L.H. s/s thread rod on Ebay. You also need the matching deep nuts. Use washers and a little grease. It all requires patience and finesse. No, there is not enough material to drill out and re-thread to M6 or an Imperial equivalent. Be careful with the bike skewer alternative.It may overwork the few little threads in the part. It doesn't matter if you wear the threads on the M5 rod/nuts.It does matter if you wear the threads in the actuator ! Compress the part in a vise(gently!!) and then insert the rod.Try to avoid using the rod to do much compressing.Keeping the part compressed with the minimum length of thread is a challenge.Then figure out how/when you are going to remove the rod. Zip ties can break under strain .....So if you use them, use the very best quality oil-resistant ones you can find..
Suggest you inspect/test/upgrade the entire SAI system. It is prone to multiple failure points that are cheap and easy to deal with now but awful later. Jake sometimes suggested Knock sensors for the same reason.
I found it helpful to use M6 s/s studs +washer+nut to hold down the 'bridges'. I was paranoid about causing any avoidable wear on the aluminum threads with steel bolts. Yes. it is a chore to measure and source the correct size/length but imho ,worth it.
A small improvement to such a tool(I have the one Ahsai suggests) is to replace the cone with a barbed fitting that will thread into the spark plug hole. Just don't overtighten it or you'll have an extraction/removal problem.This makes solo testing possible. Better is to attach it to an extension tube that threads into the spark plug hole at one end and has a standard Amflo compressed air fitting at the other end.

But be sure you get the extension tube, not just a hose. https://www.ebay.com/itm/Engine-Compression-Gauge-Tester-10mm-12mm-14mm-18mm-threads-with-extension-tube/352187634741?hash=item520004d435:g:uHUAAOSwTyZZeWon Then you can also do Leakdown and compression tests solo also.
It may help others to give a more competent opinion than mine if you : Look at the dwg in the FSM of the timing procedure. It is common(& O.K.) that the camshaft notch is not perfectly horizontal. Unfortunately , this is a bit vague. So maybe to help the discussion ,re-time the cams so the notch is perfectly horizontal and note how many CRANKshaft degrees it is 'off' . Assuming the notch on Bank 1 is slightly up(&outward) - just like the FSM dwg., I would continue and run the engine.Then asses with Durametric, re-asses after 100 miles and recheck the timing .
Thant is based on my experience and reports from others. I am sure it would be nice to have the pretensioners but they are very expensive. Be prepared for maybe having to adjust the valve timing after about 1000 miles - using the 4 bolts on the EX cam behind the scavenge pump
Schnell Gelb replied to Wausau 911's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)There is some confusion in related Threads about the significance of the foam loss in some climates. The suggestion is that the foam loss will NOT affect the a/c performance.I have no personal data for this. It is worth investigating because it is a tedious and time consuming job. BTW the best replacement for the foam is 3M Flue Tape fire-proof/high temperature tape.It is frequently cited in the "foam coming out of my vents" Threads. Clever hack version: http://986forum.com/forums/boxster-general-discussions/67109-small-foam-pieces-blowing-vents-2.html
Schnell Gelb replied to B_Zerpersande's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)If you are in a mild climate ,the coolant hoses to the AOS are redundant. Some just disconnect and plug them. Search for details and comments.
Tool for Spark Plug Tube extraction Suggest you use the long bolt+ specific washer diy tool. Just google this subject and add "Health Service" he was a Forum member who wrote up some specs and posted photos.The Transom plug tool does not work if the seals are swollen/tight.
