When it comes to connecting things to the engine, I don’t necessarily follow the order given in the manual. My strategy is to connect things to the engine from bottom to top. Working from the bottom upwards leaves everything as clear as possible, so fewer parts are in my way. This reduces working from underneath the car, which is not the easiest way of doing things and makes fitting parts easier.

The dry sump pipes that fit the engine dry sump can be identified as follows:

  • The pipe with one straight connection goes from the front connection of the sump to the oil cooler LHS.
  • The pipe with two obtuse angled connections goes from the back connection of the sump to the bottom dry sump tank 
  • The longest pipe with two right angled connections goes from the top of the dry sump tank to the RHS oil cooler. I have no intention of fitting this pipe at this stage, because the radiator or dry sump tank are not fitted yet.

I intended to install both the pipes that connected to the sump to finger tight, until the dry sump tank and radiator are installed. Unfortunately, the front sump connection hose was damaged, so I will have to wait for a replacement. Therefore I was only able to fit the rear sump connection at this stage.

During my factory visit I observed the pipe connections on the sump and noticed that Caterham use the shorter of the two aeroquip connectors for the rear sump connection. 

Like the brake lines, the oil pipes will only fit if perfectly aligned. Using the shorter connector makes this possible without having to remove the engine mount. Working from under the car it was possible to connect the rear sump connection; the hose needed to be slightly pulled to get the alignment needed. 

The hose needs to be routed between the chassis tube and the skin. I will be applying some tie wraps when the other end is connected to the tank. 

UPDATE – The replacement front dry sump pipe arrived. I connected the pipe to the sump loosely, routed it back into the chassis. This presented a new problem with my axle stand location. I will have to move the axle stand to not foul the pipe.
