RICHCAT7 Posted July 25, 2009 Share Posted July 25, 2009 Hello anyone out there can advise on the oil that i seem to get deposited on RHS wing and also on screen when doing long durations at about 70 mph, gets a bit messy when wipers go on ! K&N filters have not been over oiled either. substance is a light treacle colour Around town i do not get any deposited, engine is fresh and healthy otherwise. Any pointers would be much appreciated, Regards Richard. Link to comment Share on other sites More sharing options...
Baz Hemsley Posted July 25, 2009 Share Posted July 25, 2009 Have had same problem. Wash filters and dry, then I just spray with WD 40 every now and then. Mine are almost dry. Still get the odd spots on the wing after a hard blat, they spit back on the over-run. Link to comment Share on other sites More sharing options...
RobW Posted July 26, 2009 Share Posted July 26, 2009 Check it's not coming out of the oil seperator (under the rearmost carb) . This is a pushfit rubber cork arrangement and come loose . Link to comment Share on other sites More sharing options...
john g Posted July 26, 2009 Share Posted July 26, 2009 Rich, I had a weber flooding problem just as you describe, I adjusted balance, float levels, check valve etc. I also had a blat mail from a chap in Germany with this solution ... it worked for me and thats quite a few years back! The following is Klaus's e-mail to me. Klaus Koenig, Munich, Germany --------------------------------------------- There is another source for the leaking of Weber DCOEs. This was pointed out to my by Keith, a Weber tuning guru that I met on the Innovate Motorsport forum. I repeat this with my own words, but the credits are with Keith... The DCOE has a design flaw, because there is no seal between the auxillary venturi and the carb housing. The auxilary venturi carrys the venturi that is responsible for delivering fuel from the main jet. The auxilary venturi is simly slotted into the carb body and held in place by the grub screw on the underside of the carb. Now, the fuel from the main jet is routed from a hole in the carb body into a matching channel in the auxilary venturi, but there is no seal to prevent fuel leackage. The seal is supposed to be made by tightening the grub screw, but you can't overdo it, because otherwise the aux venturi will be damaged. What will happen now, if the seal in not perfect, is that on open throttle, when the main circuit is active, fuel will leak out of there and collect in the gap between the aux venturi and the body. Eventually it will dribble out of there and drop on you battery. This will only happen when the main circuit is active, therefore on idle, no fuel will drip out. To cure this, you can try to tighten the grub screw a little bit, or your can try to put some Hylomar between the aux venturi and the carb body. But be careful not to smear any sealant into the main circuit channel. Link to comment Share on other sites More sharing options...
alextangent Posted July 26, 2009 Share Posted July 26, 2009 Instruction on how to hylomar venturis. That'll stop 99% of the oily gunk. Link to comment Share on other sites More sharing options...
Graham Perry Posted July 26, 2009 Share Posted July 26, 2009 If you have a crossflow with a full race cam, oily gunk over the body is the norm due to fuel standoff and can't really be stopped. Mine used to do it badly on carbs but its been much better on injection Link to comment Share on other sites More sharing options...
RICHCAT7 Posted July 27, 2009 Author Share Posted July 27, 2009 Thanks very much for all your idea's , My breathing is all ok, so i am going to do the Hylamar thing and give the air cleaner a good wash through just to make sure. will also check balance. Off to the garage now ! Thanks again ,Richard. Link to comment Share on other sites More sharing options...
RICHCAT7 Posted July 27, 2009 Author Share Posted July 27, 2009 Just returned from the garage, having found a couple of loose trumpets and venturies Stripped them all out cleaned them up ,carefully retightened up venturies turned trumpet clamps round to ensure rampipes were clamped. fitted new foam piperstockins stolen from my sons garage . instead of my k&n's.

Mickrick Posted July 30, 2009 Share Posted July 30, 2009 brilliant! 😬 I love this stuff. I think I should have bought myself a Xflow. 😬 Or a BD. 🥰 Link to comment Share on other sites More sharing options...
john g Posted July 30, 2009 Share Posted July 30, 2009 No computer trickery here. The only map you need for a x/flow is how to get from A to B 😬 Yeah, how did you get on Rich. Link to comment Share on other sites More sharing options...
dalongbloke Posted August 1, 2009 Share Posted August 1, 2009 Mickrick..its not too late. FAB cars from 8Kish. How mad is that?? Andy Check out Hal... http://picasaweb.google.co.uk/dalongbloke Link to comment Share on other sites More sharing options...
Mickrick Posted August 1, 2009 Share Posted August 1, 2009 Mmmm...tis a bit, I have too much invested in a chassis now. Plus wheel on the wrong side. S3 a bit too small for me. Plus, I have to chase my dream. I have to say, I was very, very, very tempted by Kenny's little crosflow recently. 🥰 Link to comment Share on other sites More sharing options...
dalongbloke Posted August 2, 2009 Share Posted August 2, 2009 Yes... Kenny spent a lot of time on that. Car features one black harness from my car; my bench seats are from him! Top man..... I wish I could get up north for a run... would be good to meet him.

RICHCAT7 Posted August 2, 2009 Author Share Posted August 2, 2009 Hi , Sorry for update delay ! Did'nt get out for the roadtest untill today ,Mistake 1. Fired her up this morning to go to Duxford ,all loaded up Wife,picnic,etc only to find a nasty misfire on acceleration. Returned to base and proceded to strip down again,What have i done to it Fuel delivery seemed ok from pump,so filters off ,trumpets and venturi off, arhhh there,s the problem i mis alligned the venturi dimple when inserting it, thought the dimple screw was located but it was going in to the machined out area next to dimple! Result no fuel to pot. Wont do that again .marker pen on end of venturi helped refit. Back in the car all systems go ,off to Duxford . No oil was found anywhere on my return, Just one thing though car seemed jurky at 2500 to 3500 rpm at constant but over 4000 seemed fine, is it too rich ? Thanks for all your help.

alextangent Posted August 3, 2009 Share Posted August 3, 2009 Could be balance between the carbs. At light throttle loads the engine is much more sensitive to air inflow differences. Leaning out tends to result in misfires and spitting from the carbs (especially on light acceleration when the accelerator pump isn't delivering a squirt of fuel); too much fuel gets you banging and popping on the overrun (when you lift off the throttle). Or you could have a misfire due to a weak spark, or low pressure on one or more cylinders. It's difficult to tell without hearing it running. Alex McDonald Loud, louder, loudest...

RICHCAT7 Posted August 3, 2009 Author Share Posted August 3, 2009 Hi Alex, will check compressions ,think they are ok as engine is very fresh only about 1500 miles since fitting. coil is new bosch blue 12 v non ballast with aldon ignitor dizzi plugs seem to be good colour on electrode bar but sooty arround immediate area of electrode i dont get many bangs when on overun just the odd one.(except after a huge bit of welly) 😬 Think it may be time for the rollers as i am not a tuning person!
