Hi all!
Just a bit curious about the following. No matter how well tuned and well functioning my 1800 is, there seems to be quite a noticeable smell from it when it's idling. Also when it's hot. There's no black smoke or anything, but it smells like the mixture is too rich. Well, it's not, and the ignition is spot on too.
What are your experiences here? Have we been spoilt with modern cars, so we forget how cars used to smell or what? Is it possible to walk around an idling 1800 and not smell it?
I find the smell a bit annoying, going into a parking house etc, but in the end perhaps it's normal. After all, the plugs are always biscuit brown dry and as said before it runs and idles very well. Also, it hardly uses oil. Fuel consumption is always below 1 litre/ 10 kms
I don't have access to a CO meter, but it would be interesting to see what it is. I'm going to a "MOT" test soon, so will know then.
Guess I'm over picky, again.. But it would be interesting to know if other crabs smell too:-)
Tommy.

Mmmm I'll double check mine now. I notice a smell when she's warming up with the choke on, which of course would make sense.
Also that's a pretty decent mpg figure, is that on the open road?
Do they do CO readings as part of your 'MOTs' ?

Mine can smell a bit "hot engine" if you open the bonnet after a decent run, but otherwise I haven't particularly noticed anything. Snoopy11 had an issue with exhaust fumes sucking back into the car, but I think that got resolved.

I cured the exhaust smells from coming back into the car by simply extending the exhaust a few inches and putting a spacer bar in to lower the tail pipe down a bit. I had noticed at a show that my exhaust was mounted higher than others. It was Mr P that gave me the idea about the vortex at the rear of the car driving the fumes back into the car because of a lack of a decent boot seal.

Fuel consumption is mostly highway driving, not much town driving and traffic jams lately. On average it will be around a litre, I guess.
There's no smell while driving, I only notice it occasionally while walking around it as it idles.
They don't fail cars more than 30 years old on emissions here. However, as it enters the test station the exhaust draught/ ventilation tube is put on the tailpipe. You'll then see CO and HC values on a giant board on the wall anyway.
I guess I'll have to pull the cylinder head and do a valve job. It seems one valve is hammering quite badly, even when correctly set. The noise goes away if I insert a thin feeler gauge between the rocker and valve stem while it's running. Compression is Ok I think, 170 in cylinders 1 and 4, 160 in 2 and 3.

Maybe worth looking at the rocker shaft for wear /damage first? Remember Tony (Crabmaster's) photo damaged rocker shaftregards David Fuel consumption is mostly highway driving, not much town driving and traffic jams lately.
