I'm ready to firebomb my 60 and quit this expensive addiction...
I had the infamous warped intake/exhaust manifold problem due to the carb cooling fan being disconnected for god knows how long - POR. Since I had fixed it on my previous 60, I thought no problem. Here's what I have done to date:
-intake/exhaust manifold planed at machine shop.
-new OEM intake/exhaust gasket
-rebuilt carb (cruiserparts.net - they do a great job BTW)
-new insulator and insulator gaskets
-new egr pipe gasket (pipe comes off exhaust manifold)
-new exhaust donuts
-new OEM carb insulator/gasket assembly
-new OEM vacuum lines
-new HAC assembly
-verified vacuum hose routing several thousand times...
Runs great with 20PSI of manifold vaccum - only if the EGR valve is disconnected. If I connect the EGR, the manifold vacuum drops to 10-12 and barely idles.
A cruiser freak in the area was parting out an old 60, so I bought the EGR valve and switching assembly. No difference.
The truck also hesitates and jerks occassionally at highway speed even with the EGR disconnected and lines plugged.
Any suggestions?
