To replace the valve, first, locate it and then remove the hose that is connected to it. Therefore, it's important to have any leaks repaired as soon as possible by a qualified mechanic. Manifolds that have not been changed for some time are also prone to damage. Exhaust fumes contain poisonous gases like carbon monoxide, which can cause serious health problems.

Aside from putting your health at risk, the leak can cause more damage over time to other parts of the car. As soon as you notice the issue with the valve seal, you must take your car to the workshop. Poor seal and possibly too rich jetting.

On inspecting the side of the turbo that connects to the exhaust it was bone dry no oil present, bu the other side of the turbo seems to get a bit of oil, im not sure if thats normal or not.
The valve guides are responsible for sealing the gap between the valves and the cylinder head, preventing oil from leaking into the combustion chamber. They may be damaged. Afterward, it would be best if you took off the cylinder head. A popular symptom of damaged valve seals is that outgoing fumes can be grey or blue. Replace valve cover gasket.

Valve guides are an internal part of the engine that help to control the flow of gases into and out of the engine. Any idea on what components may be in that area causing this?
In certain rare cases, the head of one or more of an engine's pistons can become damaged, allowing for the displacement of oil into an engine's combustion chambers. This problem is usually accompanied by smoke, poor running, poor performance and engine noise. What can be common during an oil leak is an oil filter that is not torqued properly or the vital rubber seal on the body of the oil filter may be leaking. Nevertheless, if you notice the check engine light or reduced mileage, you must analyze the working of different engine components.

Its to the side and probably wouldn't drip on it. They help the valve work stably through proper positioning and reduce the heat created during combustion. If you can get a good flat surface on the flanges with a file, or sandpaper on the reference surface, you can use some hi-temp silicone, like the copper stuff, to help seal the flanges and the gaskets. You have two options. If you are a lazy car owner and haven't cleaned it for years, beside from our maintenance tips, we suggest checking the outside of the pipe.
