RRC EFI 3,9 first crank after rebuild

roule · Saturday at 18:53

Hi
Almost finished the job : new cam and lifters, rings cleaned and oiled, composite head gasket...check the pressure oil pump with a mechanical gauge (25 to 40 psi with drill) just a little scared to give the fist crank ...should go to 2000 rpm during almost 10 minutes ?

Take the spark plugs out (distributor cap seems to be missing ??). Then crank it on the starter motor & check the oil pressure and get the oil circulated where required.

Then I would put sparkies in & get it to fire up & idel before revving it up.

You need to follow the cam break in procedure so the lifters start to turn

Yep, no HT going to the dizzy cap or HT leads going from it to the plugs…

…and lordy, thats a lot of belts! Just have the one serpentine one on mine.

I think that's right. Don't let it idle at all once started, you need oil splashing around straight away

PS. Nothing wrong with the belts, all model dependant…

I have 10 liters fuel in the tank since 2 years, if i mix with new gazoline it's ok , or i must empty the tank before ?

It will probably run just fine.
BUT..
You want it to start straight away and rev well to bed the camshaft in.

I would pump it out, add some fresh fuel then pump that through to get the old fuel out of the system.

By all means put it back in the tank later on, it'll likely run just fine mixed with fresh
