So, I'm not sure where I am supposed to start...and finish... can you please specify what I am looking for and what I should do?With a 30yr old FD there is more than a 50% chance that it is not in spec (tiny splits in diapghram - deteriorated o-rings causing blockages in very fine capillary tubes etc etc) and i suppose before jumping into a rebuild i feel the DIY home test with the vials/glass jars to accurately measure flow from each injector line is a good start
OK, I guess I will build that smoke test DIY I saw on YouTube!The other main issue is a vacuum leak somewhere and requires a smoke test before you do anything else with the tune-up
OK, so I should pull the injectors and bench test? I am not sure how to do any of that, but I am willing to learn, if provided direction.And most important Injectors that are not spraying an even fine mist when they open (even new injectors requre bench testing before are swapped in) and injector seals that have gone hard with age and not 100% sealing.
I was not the least surpised when testing some of my injectors i have pulled and bench tested in the past - that they were not up to spec and spraying correctly
And what is the 'POT'? (Not a drug test, right?!?!) ......Thanks!Doing a test on the POT upfront I would also consider essential (an easy test to perform) to eliminate any worn tracks as an issue.
