maturin23 10 Posted December 23, 2008 Hi all, I've been getting an odd noise from what seems to be the top end of the engine. It's only really noticeable at tickover. I didn't have chance to get an MP3 so I'll do my best to describe it - it's not really metallic enough to be described as a 'rattle', nor is it solid enough to call it a 'knock' - somewhere in between, a bit like a bunch of pigeons going ko-ko-ko quite quickly Does that make the remotest sense to anybody apart from me?

Tom Fenton 1,542 Posted December 23, 2008 I once had a metallic noise coming from the top end of my Mi16 205. I started taking it to pieces to investigate and found the inlet camshaft pulley securing bolt was working its way out Luckily the engine was fitted with a cambelt cover so this was impeding its progress, or I dread to think what would have happened!

maturin23 10 Posted December 23, 2008 Thanks so far, chaps. Obviously I'll need to get the rocker cover off and have a butcher's, would a lazy tappet be obvious? Share this post Link to post Share on other sites

maxi 36 1 Cars Posted December 23, 2008 First thing I would do is check your throttle body. The screws that hold the butterflies in place often work loose and get inducted into the engine. The odd noise you hear (which from what you describe sounds just like it) could be a screw being embedded into your piston. Take the AFM to TB pipe off and check all four screws are where they should be, 2 securing each butterfly. Maxi Share this post Link to post Share on other sites
VisaGTi16v 1 Posted December 23, 2008 (edited) I had that exact issue but somehow the screw stayed in the inlet manifold and I managed to get it out! (heh you commented on that thread!) Edited December 23, 2008 by VisaGTi16v Share this post Link to post Share on other sites
maturin23 10 Posted December 24, 2008 Ouch - I'll deffo check that out, Maxi. It's not the injectors. Part of me is hoping that this is the excuse I need for a rebuild or a newer GTI6 engine Will post next week when I get a chance to get under the bonnet.

Stay Mi mate, GTi6's are wank in comparison for grin factor. Trust me you will miss the mi! Also, dont be tempted to even start the car before you check it out, you could avoid a lot more damadge.
