Hi all, After reading a post on here about the hex bolt that holds the oil filler bracket onto the inlet manifold being a potential air leak I paid real close attention whilst putting my air pipes back on last night and think I may have unearthed a potential issue. Whilst putting my air pipes back I realised that (probably forever) I've been running the car with only the four mounting bolts that go through the main bracket and gasket on my AFM. I noticed there is a small extension of the AFM mounting bracket that runs underneath the AFM and should anchor it in the side with a fifth bolt but this part of the bracket had been bent out of the way and there's never been a bolt in this location. So, can anyone tell me what size bolt goes in here please - it looks as though it may be M 8 or even M 10 but I didn't have anything handy to try. Also, would having this hole open all these years have affected the performance/idling? Would it be similar to leaving the oil filler bracket hex bolt out of the inlet manifold, thus allowing un-metered air in or am I clutching at straws? Cheers in advance for any help. Ian.
