Have a 20 Year Old Ford 4600 SU and last year it began choking out and then discharging blue exhaust under higher RPM and under load. The dealer replaced the fuel pump and it seamed to help a little.
The condition seems to be getting a little worse, so when I was replacing the fuel filter I noticed the injectors had never been changed. I replaced the injectors and the it still smokes badly.
Could this be bad valves or seats? Could a person replace the valves and seats from the top - under the valve cover? Other sugestion??
Thanks in advance!!
