PeteH Posted August 23, 2022 Report Share Posted August 23, 2022 My BMW 100Rs, would, if left unused for a few weeks, Need the Carbs re-balancing.? Very similar to Strombergs. Don`t know if that would have any relevance in this instance. Never had a car with Twin SU`s, usually just one big one?. Took about 15Min using a Mercury gauge.

daverclasper Posted August 23, 2022 Author Report Share Posted August 23, 2022 Just hoping Pete H, that's it's the PCV valve. Mine are the simplest Strom CD's. Not much to go out out of kilter generally, as far as I know?, especially as car is used regularly so parts are moving, also lowi'sh miles, so less longer term wear on components., Been dead reliable for years after a bit of simple, low cost work initially and getting to learn the in and outs (thanks to this club mainly) PS, I'm actually not by nature an, optimist!. 1 Link to comment Share on other sites More sharing options...
daverclasper Posted August 31, 2022 Author Report Share Posted August 31, 2022 Thanks folks. The DIY diaphragm appears to be working fine. Thought it might be usefull info if others ever have this issue. Link to comment Share on other sites More sharing options...

VixenPPP Posted September 2, 2022 Report Share Posted September 2, 2022 Having looked at service manuals pics of the emission the control system mine appears not to be the same. It's a Vitesse Mk11 . I hope the pics make it clears. The diaphragm valve just rests in the hole on the top of the manifold. It's clearly not as it should be. Would this cause the engine not to start ? Is there anything else connected directly into the manifold that could cause the engine not to start ? It won't allow me to post pictures. A major difference is that the manifold ' rail ' has two holes, one, on top, where the valves sits, the, other pointing forwards, just below. This has a hose connected to it which has been blanked off. Thanks....Neil Link to comment Share on other sites More sharing options...
daverclasper Posted September 2, 2022 Author Report Share Posted September 2, 2022 I have seen valves DIY style, connected with a hose from rocker cover and directly from outlet of valve to manifold (with maybe a short coupling length of hose). As long as the hoses/fittings, are sealed and not letting air in, then should work as original fitment. The blanked off hole, would be for a vacuum accessory, e.g. vacuum gauge/brake servo.

VixenPPP Posted September 2, 2022 Report Share Posted September 2, 2022 Yes, I've looked at that Pete. It's not the same. The diaphragm valve sits in the hole on top. It's not secured and is not airtight. Link to comment Share on other sites More sharing options...
johny Posted September 2, 2022 Report Share Posted September 2, 2022 Ha! Unless, by chance, its quite a good fit the engine must run pretty badly although I guess the carb mixtures have been richened to compensate... Link to comment Share on other sites More sharing options...

Iain T Posted September 2, 2022 Report Share Posted September 2, 2022 There should be a hose from the rocker cover to the pcv and a S shape hose from the pcv to the manifold. There's a fitting in the manifold and a bracket holds the pcv. If you don't have this setup you must blank off the manifold to stop any air being sucked into the intake. At the rocker you can leave it vented to atmosphere. However I would buy the correct setup or use an oil catch can instead of a pcv. As Pete said we need pics. As is it must have a 'orrid tickover.

VixenPPP Posted September 2, 2022 Report Share Posted September 2, 2022 Gents....The pics will not upload, but, I have posted on FB TSSC. It's been suggested the manifold is off a triumph 2000. It was running fine, but, something has broken and needs fixing. Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 3, 2022 Report Share Posted September 3, 2022 what happens when you try to upload its quite simple and has no capacity limit on file size Pete Link to comment Share on other sites More sharing options...
VixenPPP Posted September 3, 2022 Report Share Posted September 3, 2022 I'm told the manifold is off a triumph 2000 and looking at a picture of one it is the same. Since I've had the car it's only developed this starting problem recently, so, it will run fine with the wrong manifold fitted. I don't quite know where to go from here. What about blocking off the breather hole in the manifold completely ? Can't see why a replacement manifold is needed. Oh, you will see the pic upload worked this time, must be me.

johny Posted September 3, 2022 Report Share Posted September 3, 2022 yes that is different from standard and you could check the engine serial number to see if the complete unit has been changed. The PCV looks as if it should have an o-ring fitted to its stub pipe which then will be a tight fit and seal in the manifold connection. The other connection will have been for a servo in the 2000 but which the Vitesse never had fitted as standard... 1 Link to comment Share on other sites More sharing options...

This would I fear not be good and cause severe indigestion! 😝 Iain Link to comment Share on other sites More sharing options...
johny Posted September 3, 2022 Report Share Posted September 3, 2022 Certainly Rimmers dont show any seal for that type of PCV so it must just be a push fit in the manifold connection - pretty poor! However think the risk of rubber ingress is only the same as on my Vitesse which has a rubber hose between the manifold and PCV... Link to comment Share on other sites More sharing options...
NonMember Posted September 3, 2022 Report Share Posted September 3, 2022 There does look to be a groove for an O-ring to fit in. I'd be very surprised if it was intended to do without any sort of seal. Unfortunately the 2000 WSM only shows the Mk1 version, which is the same as the Vitesse.

johny Posted September 3, 2022 Report Share Posted September 3, 2022 I know they were notorious for a saving a bob or two but surely the PCV could bounce around like that! Maybe the bonnet kept in it place🤣 Link to comment Share on other sites More sharing options...

The engine number has a ME prefix which indicates it was originally fitted to a Triumph 2000. The PCV must be air tight surely. I'll try an o ring and see if it makes a difference. I've tested the compressions and all cylinders gave readings of 140/150. Thanks....Neil Link to comment Share on other sites More sharing options...
