I have Toyota Cressida 1979, Since couple of weeks I am trying to locate Intake vaccume leak which is giving bing pain in driving. My whole care is getting shaky while drive more than 30 Km.
By long efforts I feel I reach to the point. It is hose coming from Intake Manifold to PCV on Tappet Cover. I had already change the hose and PCV and PCV Collar seal , by just tightning i got 5 % improvement in leak.
I want to ask Does Tapped cover Rubber Gasket can also play part of leak? because I had open it 3 times before to adjest tappet and I did not put any special glue for it and I was also looking old.
Looking forward
Regards,
Rizwan
