I have torn a 3.4L all the way down to the crankshaft. Did the whole project over Thanksgiving weekend.

The engine was a long block and on an engine stand -- so I did not have to deal with extracting it out of the vehicle.

it is relatively easy to tear down. Assembly is not hard either -- but timing it is the tricky part.

what is wrong with your head(s)?

Ok I just read through some of your other posts....

You're trying to replace the variocam solenoid.

You do not need to pull the heads for that. You will need to pull the valve cover.

You might not even have to pull the cams to replace the tensioner solenoid. -- but I suspect you will.

The difference between this and pulling the heads is that you do not need to take out the lifters, lifter tray, and remove the headbolts,

and replace the head gasket.

you will need to retime things if you have to pull the cams. which means some special tools. you will probably should have a cam position

holder tool even if the job can be done with cams in-- this hooks into the end of the cams and bolts into the heads temporarily, and locks

the cams in position.

I'd say it can be done as a DIY -- not sure how easy it can be done inside the car -- might be possible.

much easier if you drop the engine and put it on a stand.

Hi mike thanks for the info.. The reason for the head removal was that my exhaust bolts had all snapped when i had to remove the Exhaust Manifold proir to me changing the Solenoid valve. The Solenoid valve was on the 4-6 bank and not a problem , just the fact that i had to remove the Manifold equated in me having to snap the bolts ... Porsche why oh why didn't you use stainless steel bolts!!!! on the manifold

From MY03 are the exhaust manifold bolts better quality and much easier to remove for all M96 engines, it's a consolation.
