Sounds like you have a possible head gasket leak internally. The white gunk is a mixture of oil and coolant. Check your oil dipstick if its creamy in color too then quite possibly. Check the coolant level, if low then I'd definitely suspect it going into the oil. If both oil and coolant look good than it could just be regular blow by condensation. check the air filter for restriction, and the PCV valve for being plugged up.

I have vapour / steam coming out of my oil dipstick tube on my 1.8 diesel Ford Galaxy, is this to do with a faulty / worn pcv unit. Would this also contribute to poor starting if the valve is faulty?

The PCV allows one way flow and vents pressure (gases) from the engine and sends them to the intake side of the air breather for re-introduction into the air intake system of the engine.
A non-working or stopped up PCV can cause a build up of pressure, which must vent somewhere. The oil dip stick is often the choice, especially if there is not a tight seal at the top of the tube.
White smoke or steam/ vapor usually means water is entering the internal workings of the engine. Head gasket leaks, cracked heads, and cracked blocks are the common source of such entry. Also water leaking into a cylinder will cause hard or poor starting as the piston is working against the volume displacement of the water. Upon cranking any water so leaking will be exited through the exhaust system and leave the vehicle as a white vapor out of the tailpipe.
Considering that most diesel engines have some "blow by", some water may be expelled out the PCV circuit.

Peugot 106 got warter under rocker cover and white creamey gung going from the breather from the rocker to the air filtter been told its not head gasket

So it's not the head gasket? And you are still losing coolant? Well, okay, you will have to find how the water is getting into the rocker, and whether it's your lost coolant or plain water. IDK, possibly an intake manifold leak?
Even though the oil looks clean, the water and gunge in the rocker area will drain into the sump and contaminate the oil. If it's not the coolant, run the engine until it is hot, then give it a few minutes for the oil and water to drain down from top of the engine into the oil sump. Then change the oil and oil filter. Good luck, hope you find the problem.

I have a 92 Isuzu pickup with a L4 2.3L. that recently started idling rough and idles up and down when stopped. It has 111,000 miles on it. It runs fine once I take off.

no check engine lite? if not pull the air intake tube and look for a dirty throttle body. the idle air valve may be unable to seat so it is searching and needs cleaning. use a carb cleaner that is safe for throttle plates. and use your finger to rub around the plate to clean the gunk off

My 92 5.0 thunderbird started to idle rough then after a couple days began to surge and when you accelerate car runs rough to about 2500rpm`s but seems to be getting worse

It sounds like you have a fuel problem. You should replace the fuel filter before trying anything else, and when you do, dump the old one into a CLEAN container and look for water. Dirt should be taken care of by the new filter. If you do have water, you will see beads in the container. Get some isopropyl alcohol or gas line antifreeze from your automotive dealer.

Engine runs rough at 40-70mph, code p1399, p0300, p0301, p0302, p0304, p0305

have your codes cleared and as soon as your light comes back on get it checked right then. usually the first code that pops up is your problem,. and can cause faulse codes to follow. check your mass air flow sensor,. make sure the breather tube is on good and no cracks or tears in it. check fuel filter also hope this helps you in the right direction
