Timbo 0 Posted December 5, 2009 I've got an unexplained odour inside my 94 VR6 at the moment. Like any smell it's difficult to explain, but it's definitely not a brake smell and it's not really a burning smell either, nor does it strike me as being electrical. The closest thing it smells like is gear box oil. I changed the gearbox oil earlier this year, but I'm struggling to understand how gearbox oil would get inside the car, particularly as the engine bay doesn't smell at all. I also changed the exhaust recently, so it could be a leaky connection between the down pipe and the cat, conceivably. It's too dark to get it jacked up and check now, but I'm going to do this tomorrow. Could it be the clutch? I've never smelt a burnt clutch before but as I say it's not a hot brake smell, which I believe is similar? If it makes any difference it's quite persistent; I first noticed it last weekend and the car has been parked since then, but it's still strong a week later. The other thing I've noticed is that it seems to be stronger nearer the roof than in the foot wells, implying that whatever the gas is it's lighter than air. Anybody got any bright ideas what it could be? :shrug: Quote Share this post Link to post Share on other sites
Toad 0 Posted December 5, 2009 Your PCV valve is cracked and oil is dripping on the exhaust manifold. Possibly. Quote Share this post Link to post Share on other sites
Chris 0 Posted December 5, 2009 Your PCV valve is cracked and oil is dripping on the exhaust manifold. Possibly. agreed, sounds like its venting into the engine bay through the crank vent Quote Share this post Link to post Share on other sites
Timbo 0 Posted December 5, 2009 I had a little look in the dark and it seems dry. I actually replaced the PCV valve last year anyway so it would be quite soon for it to have failed already. Also I ran the engine for a few minutes while I was out there to see if I could see any evidence of drippage onto the manifold/downpipe and I couldn't see any. It was dark though so I'll have a closer look tomorrow. I did notice number 2 HT lead arcing onto the block where it goes into the coil pack though :roll:.

fla 9 Posted December 5, 2009 A slight aside - should the pcv 'rattle' if you shake it? Mine doesnt at all, i'm wondering if it has got stuck after i stuck the broken pipe portion on with industrial superglue :? Dont want it to suddenly explode!!

Timbo 0 Posted December 6, 2009 So I worked it out. I keep a can of oil in the boot for emergencies. I probably don't need to explain the rest, besides to say I'm going to be stripping the interior out next weekend and attacking it with a strong shampoo. :censored: :censored: :censored: Feel free to :lol: at my expense.

colinstubbs 0 Posted December 6, 2009 So the oily smell was oil eh? Who'd have thought it!! :lol: :lol: My 5l bottle in the boot is behind the right wheel arch and held in place with a luggage strap through the rear bulkhead holes that are there and the handle. :wink: Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted December 6, 2009 i only keep a litre in the car at anyone time and it fits nicely in a plastic holder with velcro on it, so it can be stuck to the arch carpet. Quote Share this post Link to post Share on other sites

But what i did is once the litre bottle had run out, i just keep it filled up with a 5L bottle from the garage. Quote Share this post Link to post Share on other sites

mcjohnruther 0 Posted December 29, 2009 Have the garage recheck your car fuel hoses and vapor recovery system with the engine running. Have them pay close attention to the fuel injectors, you may have injectors that are leaking. Quote Share this post Link to post Share on other sites
