some vectra breather help, please

[Col]

hi

got a 96 2.0 16v vectra, been having some oil leaks in the region of the bell housing, and its got worse, but checked to 2 breather outlets on the cam cover.

there is a small one and a larger one, how big is the hole in the small on and how big is the hole in the larger one?

in the larger of the 2 , there seems to be some restriction, and it is very blocked with carbon, the smaller one i can just about get a tooth pick in, should i clean them both out to the size of the pipe?

Colin,
A little confused by your description as there are three breather pipes on this engine. As you look at the engine, there are two pipes at the top left and a third at the bottom right. This one may have a black box about the size of a ciggie packet in line or, may just be a 90 deg pipe. This is the main crankcase breather and if detatched, will almost certianly be full of crud. Clean it all out and reassemble. It is worhwhile going to your friendly VX dealer parts dept and getting the black box breather mod mentioned above. Regarding the other two, the bigger one which goes from the rocker cover to the inlet tract above the throttle body should be clear. the smaller one will probally be blocked. Very common. Remove the pipe from both ends.You will find the pipe clear. The blockage is at the throttle body. Get a big saftey pin and push it through the throttle body pipe, then clean it out with carb cleaner. Whilst your there clean the entire throttle body with the cleaner as well. That will put your breathers right. If it's got the breather mod, Check the pipe clips havent cut through causing an oil leak. Also check rocker cover gasket for leaks. Hope this helps Bilko130

cheers

will try some of the tips, i suspect if there is a build up of pressure with blocked breathers the oil will find itd way out every where!
