Variocam Solenoid

I am faced with replacing the solenoid and actuator for the variocam on my '99 Boxster.

Has anyone done this job themselves? I have read about people taking their cars to the dealers for that, but my nearest dealer is over 100 mi. away and I have always done my own work.

I am thinking about dropping the engine and replacing the clutch and doing the IMS upgrade at the same time. Can the solenoid/actuator even be done with the engine in the car?

I just got this car, so am not yet fully familiar with it.

I think the solenoid is relatively simple to replace and one can do it with the engine in the car. My impression is that replacing the actuator is much more challenging because one must remove the engine and cam to do so. More experienced people can provide better guidance here.

fwiw, I had a failed variocam actuator. Replacing this requires re-timing the cams so 24 valves don't go crunch. Not sure if a variocam solenoid requires the same issue or if the term is being used interchangeably. fwiw, my work was done with engine in car by a shop. not cheap.

Changing the solenoid does not require retiming the cams, changing the actuator does.

What has to be removed to get access to the solenoid?

The cam cover on that side. You are also going to need a cam holding tool:

Thanks so much. I understand what I am dealing with now. I will get the holding tool and proceed. The cam cover sealant, is it "special" or are there equivalents?

Hi, 99 boxster,going to replace solenoid on bank 2. The diy project has instructions to loosen the chain tensioners but I'm not going to remove the cams, Iím just replacing the solenoid and maybe the chainrail if it's worn. Is there any need to loosen the tensioners? Thanks v
