Saw this, 250527579764 on ebay, what do people reckon this will help or not or is it a gimmick, i have seen something like this on top fuel dragsters but theirs are massive compared to above.

If you fit it properly then yes they are better for your engine. You need to fit this in between your cam breather in the intake pipe. All that crud you see in your TB is from the cam breather, this will stop all the crud and still burn off the vapours. You wont get any performance gains but will help keep the intake cleaner.
sorry whats TB, so the crud thats collected, does that damage engines then.
throttle body
0-Large smile ......every time it's driven
Expect around 5% increase in BHP... Seriously, it's a very under rated mod for any car.
They stop the engine having to burn up oil vapour, oil vapour diluting your fuel/air obviously reduces power.
Oil vapour sticks to your inlet manifold and in cars with idle valves it will eventually bung them up with black sticky stuff (Peugeot/Citroen have this issue). It also leaves a residue on your inlet valves which could lead to valve sticking.
(which if I recall correctly was a problem on the early VX 2.0 16v engines?)
So why are they fitted? emissions!
It's illegal to vent pure oil vapour into the atmosphere. Your car will probably fail its MOT on emissions because the tester will be looking for an amount of residual oil vapour in the exhaust gases and with a catch tank you'll have no oil vapour in the exhaust gas at all unless your piston rings are ******ed.
Manufacturers really don't care about the damage that oil vapour can do, because cars aren't designed to last long enough for it to become a problem and once outside warranty period it's fair game.
I have made a kindeof oiltrap on mine DTi. Have a look here
Even if I have removed the trap, and only use the extended hose, it is enough to prevent oil to be sucked into the inlet. So, my experience is you dont need the trap, but its enough to extend the hose. Well, at the 2.2DTi at least
BUT, the inlet is not dry yet! The turbo is leaking. Very small amount, and after my Opel garage told me, completely normal, but its enough to still make the inlet a bit sticky, unfortunately.
Now, if you look at the post I linked to, I have also made a gasket to block most of the EGRvalve. I have also disabled the throttle blade completely. Together, this is very effective. At least so far No fault codes, no hickups, no more loss of response/cut-outs from engine. Just pure fun driving
