Help needed: Boxter fails to restart after rebuild / windows no longer work

[Jake Raby]

There's a ton of tricks with these cars, some are so simple but offer so much benefit. Thats why I instruct as many classes as possible and we give away a ton of "silver bullets" in each class.

If you carried out a retrofit and now have cam adjustment issues, the timing probably moved. This is why we have done everything we can to keep these components away from the DIY installer, because few are able to pre-qualify their engine and do things like check for timing deviations before the process is done. That means the engine is retrofitted and then it may have a problem in the short term, and the first thing that pops up is our component.

In the past two months we have disqualified 5 engines that came to us for an IMS Solution. Most of these were disqualified because of worn valve train components that were leading to valve timing deviations. These will set a CEL soon after our work is done and then we get the blame for the whole scenario- I avoid finger pointing contests at all costs. I've had cars driven 6 hours to me for an IMSR procedure and then found enough conclusive evidence to disqualify them for the procedure, even though they run perfectly and have no symptoms.

Every M96 is guilty until proven innocent when it comes to pre-qualification, especially 5 chain engines as they have more VVT components and are prone to wear.

If timing is only a degree of two out before an IMSR, it can "jump" enough to create cam deviations when the IMS is retrofitted, and at that point its all luck, either good, or bad.
