1977 5.2l 318 dodge b200 van

[77dodgeman]

so i read all the replies and yeah in hindsight should’ve done a compression test, yes i’m a young’n yes a 77 dodge van is great first vehicle maybe one with a better motor but besides the point, i’ve taken the valve covers off and on both sides done a very basic inspection of everything besides looking like it’s got 40 years of wear and debris it all looked good, all push rods and rocker arms we’re moving freely except three back two on the driver side and first one on passenger side, i was able to get to push rods to spin so i don’t think there bent but nonetheless, i’ve also done distributer cap roulette and cylinders 6,5,7 i believe to be misfiring because when i pull those ignition wires from the distributer cap nothing changes, the carb has also been redone since i’ve got the van(by a certified mechanic) but i do agree something is up with my carb and something me be happening to my fuel delivery system, and for the person who mentioned my hose setup i completely agree i’ve been scouring the internet forums and it just don’t look right. and for the anyone wondering yes my wires are usually better than that i had double checked my firing order so they were still messy. i’ve also got a photo of the spot from my exhaust i don’t know if that’s just carbon build up or super rich fuel with possibly oil in it, and again i appreciate all the input and information

okay, first, good on you for recognizing a problem and jumping it and trying to fix it.

second, those plugs look horrible.

which brings us to this:

all push rods and rocker arms we’re moving freely except three back two on the driver side and first one on passenger side, i was able to get to push rods to spin so i don’t think there bent but nonetheless

yeah, that's not bueno.

the back two on the driver's side? that's 5 & 7, the two that you mention when you pull the wires nothing changes. so, i'm *guessing* that you've got stuck valves or collapsed lifters.

but yeah, all the rockers have to, ya'know, rock.

so, step one: baseline diagnostics

without this you're just rolling WAG's and shotgunning parts.

you need a compression tester, a leakdown tester, timing light, vacuum gauge. if you're planning to make a lifestyle of this, you should buy these. but you're young and broke, so get thee to ye olde parts store and rent them.

a compression test will let you ascertain if the motor is healthy. it allows you to get an idea of if your rings, valves and headgaskts are in good condition. basically it'll let you know if you have enough squeeze to get it to bang in the cycle of: suck, squeeze, bang, blow.

a leakdown test will give you a clearer picture. if something is leaking, primarily the rings or valves, a leak down will pin point it.

a vacuum gauge is an enormous help. it can tell you if the timing is late, if you have sticky valves, if there's a intake leak, if there's a restriction in the exhaust, and on and on and on.

you'll need a timing light to set the timing.

so before you start adding half a dozen hose clamps to your fuel lines, upgrading to HEI and pulling a motor for a rebuild, get a baseline and see what the condition and health of motor is.

oh, and put a washer and clip on your throttle return spring arm. you don't want jumping off there at exactly the wrong time!
