At the seam of the head to the bottom of the engine there is a significant seeping of fluid. (Think it is oil but not sure if just darkened coolant) The engine over heats. And I am servicing the camel soon and waterpump checking ther most at and the fan for low speeds. And hoping it may help But I'm pretty sure enough damage is done. With doing a compression test, would it just tell me that there is a problem of would it show towards one way or another? If the head needs skimming will this affect the injectors as they are built in. Hoping for rich (edit from rick. Stupid auto correct), d block, tdi owners or anyone who can help to chime in.
