daverclasper Posted August 11, 2017 Report Share Posted August 11, 2017 Hi. would a fine spray of water work, to temporarily seal any leaks and therefore alter idle speed please?. Thanks, Dave Link to comment Share on other sites More sharing options...
JohnD Posted August 11, 2017 Report Share Posted August 11, 2017 No. Whatever made you think it would? A burnable spray - WD40, brake cleaner - will temporarily increase revs, but are you concerned about that inflabbabilty? JOhn Link to comment Share on other sites More sharing options...
dougbgt6 Posted August 11, 2017 Report Share Posted August 11, 2017 I have had a catastrophic manifold leak, engine no start. But what's happening that makes you suspect there's a leak? Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 11, 2017 Report Share Posted August 11, 2017 In the emmision dept we always had a pump oil can with petrol in for this, it wont fire , but the revs will increase if it sucks any in , never use brake fluid ,,,,, that will fire up from the exhaust heat pete Link to comment Share on other sites More sharing options...
daverclasper Posted August 11, 2017 Author Report Share Posted August 11, 2017 Hi. and thanks. Idle has suddenly gone a bit high and won't go any lower with idle screws backed off and nothing sticking on the cable/linkage to prevent shutting down. Plugs quite paler than usual. John. I thought if a smallish leak, then spraying anything would alter running a bit, for a test, and waters sort of, free,ish and won't harm.

Clive Posted August 12, 2017 Report Share Posted August 12, 2017 All plugs paler than usual? Have you checked the rocker breather system? If a vitesse then the breather valve is a suspect that needs to be investigated. Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 12, 2017 Report Share Posted August 12, 2017 Yes bens idea undo the thottle clamp connector make sure both are closing reset with equal turns of the idle screw 1.5 turns from just touching then retighen the connecting clamp. And to add to clives thoughts rocker cover and oil filler cap gasket sealing 1 Link to comment Share on other sites More sharing options...
