Quick EGR/Weber swap question
Posted 14 November 2012 - 06:20 PM
Am I supposed to cap the large brass piping coming from the EGR (EA81)? Or is this supposed to be connected to a vac source as well?
I've heard of people swapping SPFI EGR's over as this model doesnt have that brass piping. Would this be the route to go?
Also, I've temporarily capped off the ASV hoses after the silencers with large sockets. Is this sufficient for now? or is it not effectively blocked when capped above the ASV?
BRAT runs alright but seems to have a bit of a misfire/hesitation when at idle and the carb cleaner test indicates a vac leak near the EGR so I hope this is the issue... Once the vac leak is fixed I can properly tune the carb

I have had a few of those lines crack, leading to a vaccum leak.
As for blocking the ASV. Best to do so at the spacers on the exhaust.
Cut the tubes, crimp them shut, run a bead of weld is best.
IF,,,, the nut at the spacers will turn out, then cut the tubes, spin nut out and pull the cut tube. Then, install a quarter in the spacer, replace cut tube end and nut.
