Hi

I have an oil leak from what I think is the ace valve block drivers side half way down the sill
Are there o rings I can replace or is it normal a new valve block 61 AB 5.0 supercharged rocket

Looks like the o rings are generally serviceable items:

The valve block directs hydraulic pressure to the actuators via solenoid operated directional control valves. A solenoid operated
pressure control valve regulates the required pressure to the actuators. The three solenoid valves are controlled by signals
received from the dynamic response control module. A pressure transducer monitors the pressure generated by the Pressure
Control Valve (PCV). A serviceable high pressure filter is installed into the underside of the valve block and filters the hydraulic
fluid before it reaches the control valves. The filter must be changed at the intervals defined on the vehicle service schedule.

The two Directional Control Valves (DCV's) are fitted to ports in the top face of the valve block. The DCV's are screwed into the
valve block and are sealed with O rings. Each DCV has a solenoid for electrical operation of the valve. The solenoid is sealed to the
DCV with two O rings and secured with a threaded nut. The nut, coil and O rings are serviceable parts. The DCV's are
non-serviceable and failure of a DCV requires replacement of the valve block assembly.

The PCV is fitted to a port in the rear facing end of the valve block. The PCV is screwed into the valve block and is sealed with O
rings. The PCV has coil for electrical operation which is sealed to the PCV with two O rings and secured with a threaded nut. The
nut, coil and O rings are serviceable items. The PCV is non-serviceable and failure of the PCV requires replacement of the valve
block assembly.

The pressure transducer is located in the forward facing end of the valve block and is sealed with an O ring. The pressure
transducer measures the hydraulic pressure and returns a signal to the Dynamic Response control module.

A high pressure filter locates in a port on the lower face of the valve block. The gauze and fibre filter is sealed in the port with O
rings and is secured with a threaded cap which is also sealed with an O ring. A threaded hole in the lower face of the filter allows
a bolt to be fitted to remove the filter from the port. If a system hydraulic component is replaced, the filter must also be replaced.

Four ports are located on the forward facing end of the valve block and two ports on the opposite end. Each port is fitted with a
seal pack which contains two O rings and backing rings. The pipes locate and seal in the seal packs and are secured to the valve
block with studs and nuts

So fingers crossed!

2008 TDV8 - it was a labour of love and is much missed

Thanks

I best clean it up to find what bit is leaking and get a box of mixed o rings 61 AB 5.0 supercharged rocket

I've just replaced my front ACE pipes on my TDV8

2010 model, pipes completely rotten.

They are sealed by little o-rings in the valve block, i was replacing the pipes and found it would be impossible to get them out of the valve block without destroying them.

The valve block has a filter in it behind the massive hex plug it could be that which is leaking.
