gemery10 Posted February 11, 2006 Share Posted February 11, 2006 My 86 l series sube has been giving me no end of grief and I'm thinking of swapping the carb to a weber. What do you guys do with emissions vacuum hoses and crankcase breathers? Specific details would be great as there are lots there. For those interested I have: cleaned and replaced pcv valve run can of upper cylinder cleaner through vacuum lines replaced plugs and leads, rotor cap and button tensioned timing belts (from htkysa) rebuilt carb and I still have pinging under load in summer:confused: Quote Link to comment Share on other sites More sharing options...

GLCraig Posted February 11, 2006 Share Posted February 11, 2006 Have you cleaned the EGR system and verified that it's working properly? Quote Link to comment Share on other sites More sharing options...
gemery10 Posted February 12, 2006 Author Share Posted February 12, 2006 My timing was pinging at 8 so I backed it off a bit and that fixed it for a while, then after 2000k trip on way home it pinged no matter what and really bad. I don't have an egr valve as its an aussie soob Yesterday I found the left side timing belt had about an inch of slack so I took that out as well. With that and the seafoam its run the best it ever has but i'm still thinking weber as the jetting has always seemed too lean for this weather. Can anyone tell me how they de emissioned it?
