Fumes in Cabin

[pte123]

Hi, I wonder if someone could help. I'm getting engine fumes into my cabin. I just purchased the car about a month ago. Doug on the M100 facebook suggested I look on here for a thread by Marie, but I've looked a lot and can't find anything.

I looked in the manuals and I think the air goes into the cabin though this area on the passenger side (I have a Fed LHD car). It looks like someone has installed a rodent stopper here. Am I missing anything that may help blocking the engine fumes?

Help appreciated!

Sorry to hear about the fumes. Well the engine bay doesn't even smell like engine fumes, so that is weird. Maybe your evaporative emmisions control canister is leaking? That is under the plastic tray that the convertible top rests in. Are the fumes when it is at rest, or when you are driving? I assume top up and windows up? Are the fumes stronger in one area over another?

Thanks Matt. I'll do some more investigating. One thing for sure is that I haven't had the top up since I had the car, hence one of the reasons why I thought it was coming in through the air con (I did have that on as it's been over 90 degrees in Boston) and I've mainly been around town. Cheers!

What fumes though ? Exhuast fumes ? Hot engine fumes/smells ? Petrol fumes ?

That's the one! The "rodent stopper" is (I believe) simply the remnants of what should be a complete hose/duct that allows fresh air to be drawn in. The remainder was probably foam that self-destructed over the years. I can't seem to find the post to which I referred... but I did end up buying a replacement from LGM, back in the day. At any rate, here's a picture and the official part number:

If you want to avoid having a bit of foam gradually degenerating ain the future it is possible to fabricate a suitable item using a piece of rubber inner-tube from a tire (I used motorbike one, but anything will do)...... just wrap it round the join , add a smear of rubber glue along any joints and a cable tie at each end - job done!
