If it still continues to leak from broad area of the timing chain tensioner, it may be (also) leaking at the junction of timing chain cover and head which is a well defined weak spot discussed frequently on this forum. I have had success so far using a two part epoxy (JB original) in reducing leaking by 90%. It has held for almost 2 years and 20,000km so far avoiding a more costly and time-consuming repair. This tip was courteous of a mechanic who was very familiar with these engines. His obscure post on another forum was the result of scouring the internet for several hours and he was right that you can achieve a 90% reduction which is very acceptable in light of the fact that the B235'd are always sweating here and there. You need to remove the top engine mount (see other posts or Haynes) and cleanliness is next to godliness. Lots of effort cleaning the gunky oil up, sanding/filing to increase adhesion and ending with a dry surgically clean surface for the JB. I am also careful in not overfilling the engine with oil. I try to keep the level 1/8 inch or so above the top level mark and don't mind if it burns/sweats down to mid point by it's next oil change at 8000km -10000km OCI.
