Fuel Injectors

[VON RUBEN]

so my mechanic tells me that the motor is fine compression is good so he believes that it is the fuel injectors? how hard is it to replace these??

Im not sure on the 460, but i know on my 351 they were held down by a couple of bolts, also i think the upper intake plenum had to come off, but again im not sure what the efi 460 looks like. replacing them is cake, getting to them will be the hardest part.

I had the injectors on my porsche cleaned and tested, cost me about 140 bucks for 4 injectors, brand new caps, o-rings, injectors were sonic cleaned and individually tested to make sure they were working and firing correctly...

DO I NEED TO UNPLUG AND MOVE A BUNCH OF $HIT?

If it's like my 351W you will probably need to take the upper intake off but it's not too hard-- just 6 bolts. You'll have disconnect the intake ducting and some of the sensors at the throttle body too...

thanks. im doing the repair myself since the mechanice wanted $650 just to replace 3 fuel injectors. does this job usually cost that much at a shop? it just doesnt seem to be that hard or time consuming!!

If the intake has to come off that is not that far fetched because they are probably factoring in that the bolts break a lot of times and it depends on how much the injectors cost.

if your gonna replace 3 ya might as well replace all of them......

The upper intake bolts should not break-- theyre not near any fluids (for corrosion) and they don't take very much torque.

truth!^^^ never had one break on me before on any vehicle i've worked on..

Yeah if you don't run into people that over torque them or cross thread them. Around here a lot of people try to play mechanic and they have no clue. Like the person I met who took 6 hours to change spark plugs on an S-10 blazer
