I have a 77 silver shadow srf31065. The exhaust smells horrible. Nobody can be within 20 feet of the car when its running. I cant drive it in the summer, (and it is a summer car, as they all are) because of this. I has new plugs, wires, cap and rotor look ok, seems to run ok, but lots of soot and a horrible smell coming out the exhaust. does this car have an o2 sensor or a catalitic converter, and if so, could this be the problem? Any help is appreciated. (Message approved by david_gore) | ||

Hi Gus, You haven't described the smell. Is it very rotten egg like? Has the fuel been in the tank for years? It could well be a poisoned catalytic converter. Have you had the CO levels etc tested? SRF chassis. I think your car probably has a CAT, and an early fuel injection system? You should be able to tell by looking at the exhaust system and the engine. (post photos if you can't tell )It may well have been modified from standard in the past 20 years. You haven't said where you are , is it Canada? Find out what emission levels are allowed for it to pass any local tests. I suspect that it will be much more lenient that the car was designed to pass and you could probably do away with the CAT (instead of buying a very expensive replacement), get the car running properly and still pass with flying colours. If the car has "unleaded fuel only" stickers, it will be because of a CAT. I don't think that smaller (unleaded only) restrictors were fitted in early cars filler pipes (?), so it was easy to full up with leaded by mistake. | ||

Thanks Paul.Yes, it is Canadian and unleaded. It has 3 mufflers (2of them cats?) per side but I cant find an O2 sensor. No fuel injection, it has SU carbs. Fuel is fresh. I purchased it last year, and chassis wise it's in great shape, but was a bit neglected mechanically, original plug wires, gas hose on l.p. hydraulics, dire need of oil change, and the like. I've got all new ignition components on,runs MUCH better,am currently flushing hydraulics and putting on correct hoses. It burns no oil, my concern is just the exhaust smell. I dont know what rotten eggs smell like, can they be this nasty? I notice someone before me put recently put on a couple new pipes and mufflers, they didnt do a complete exhaust repair, (still has leaks), I'm going to have what's left replaced. The exhaust manifold gaskets leaked,(I changed them), could this be indicative of high back pressure from a plugged cat? She runs like a charm except for this awful smell.

Hi, I'm currently doing hydraulics on my SS II, SRF31065. I'm changing all the hoses, a resevoir filter, the fluid, and cleaning the resevoir. Does anyone know the correct/easy way to flush the RR363 and bleed the system? I have 12 liters of 363, and would like to do as thorough a job as possible and hopefully have some left for a future fluid change. | ||

Hi Gus, Use Dot 4 until it bleeds completely clean, allow it to run very low (but not low enough to suck air in. then bleed with 363. If you are doing it with the reservoir lid removed, you can depressurise the system, suck the remaining DOT 4 out, then fill with 363. (** cover the reservoir before depressurising**) Now bleed with the R363 |
