Sunny Fl Problem
Saint Petersburg, FL
my ? is actually about a 1989 camero RS coupe with a 6 cyl. 2.8 car was sitting for a year but ran fine before that starts when carb cleaner is sprayed in air intake but dies out. I didn't hear fuel pump running checked fuses, rely and elec. curcit all fine changed out fuel pump which is now pumping fuel but I broke the ventilator valve assembly/fuel tank vent valve (Haynes book calls it ventilator valve assembly)(looks like a little canister with only one end attached to a hose)cant find the part anywhere they say its discontinued. Would this keep the car from running/starting? will engine run without it?
check engine light was flashing replaced all coils checked all injectors (all firing) replaced computer (brain) check engine light went off. still misfiring compretion test numbers were between 125 and 140 except one cyl was at 25 pulled passenger side valve cover. valve rocker had fallen out now the hydrylic lifter wont seem to hold rocker in place got it to stay in place for a short period of time (very short period of time) but ran well for that short amout of time before it fell back out why wont the rocker stay in place? lifter was pumping oil out so figured it would have enough oil pressure to hold it in place please help. thanks
