Ok guys I had just replaced my head gasket and a 1.8t b6.. I replaced the timing chain tensonor as well. But now when their is a load on the cams the tensonor collapses and then resets.. causing a terrible chatter was I by chance to prime the chain tensonor.. or could I have low oil pressure.. because around 2000 rpm the chatter goes away and it smoothes out and sounds great.. and how could I perform a oil pressure test.. any help is greatly appreciated. . Thank you
