Looking for picture inside Boxster 2.5 engine - cam cover removed

[jcorallo]

Hi,

Has anyone got any pictures of the Boxster 2.5 engine with the cam-cover removed, and maybe a picture of inside the cam cover?

A picture tells a thousand words and all that - I cannot tell from the workshop manuals if its the cam cover that holds the camshafts in place, or if the camshafts are bolted to the head with saddles. I wanted to know if you removed the cam covers, if the cams would just flop out... and if I needed a special tool to hold the cams in place when removing/installing the cam cover.

You need a special tool to keep the camshafts in place. The shafts are bolted to the head just behind the timing chains, the rest is hold by the cover. It can happen that the timing chain jumps over or that the shaft breaks if you remove the cover without the tool. If you decided to remove the cover without the tool, be sure that the cylinder nearest the timing chain is on his TDC end compression stroke. I have no pics sorry, it's all from the head.

At the dealership I have seen the cam covers removed on different cars over the years, to reseal them because of oil leaks. There is a tool to hold the cams in place, but I have never seen the mechanics I know use it.

They do what RFM says. The engine is rotated to TDC so that the cam lobes are not depressing any of the tappets. If you do not do this and remove the cover without the tool in place I was told that a camshaft can break.

I don't think I have any pictures. I did see this picture on a photo hosting site, but I don't know who took it. Please note the engine is on a stand and has been rotated.

Thanks Tool Pants, that really helps.

Its hard to tell, but it does look like the cams are sitting slightly out of their journals at the far end, but I guess that is to be expected given how they are held in.

At least it seems the cams wouldnt just flop out if the cam cover was removed, with the engine still in place in the car.

Regarding the VarioCam solenoids - do these just operate an oil pressure control valve? Or is it the solenoids themselves that move the cams?

The gold colored solenoide command the variocam mechanism.
