Siempreloco Posted March 18, 2013 Report Share Posted March 18, 2013 My truck is spitting, backfiring, and all around running like hell and is undriveable, it happened almost out of nowhere, i have an L16 in my 73 datsun 620. I popped the hood and looked around, i found a wire broken off of a solenoid that screws into the side of the intake manifold, looks like it has to do with vacuum in some sort of way, my phone doesnt want to take pics so i know it's not helping that i lack pics, but first of all: do you think this is my problem? and secondly- what would the part be called and where could i find it? ive been searching around with no luck. The solenoid is a metal cylinder probably 1 inch in diameter with a pointed metal plunger, its hooked up by wire(obviously) and is threaded to screw into the manifold. Any insight would be extremely helpful. Quote Link to comment
Laecaon Posted March 18, 2013 Report Share Posted March 18, 2013 Points or ignition condenser... Quote Link to comment
datzenmike Posted March 18, 2013 Report Share Posted March 18, 2013 Vacuum control solenoid for turning on the flow guide valve that sucks fumes from the tank and sends to the PCV. Just make sure there is no vacuum leak and it should run ok. Quote Link to comment
Siempreloco Posted March 18, 2013 Author Report Share Posted March 18, 2013 If I have a dual points distributor and I am only running on one set of points, but the condenser hooked up to the non-running set of points is messed up, will it cause issues or does it not matter? I found the secondary condenser with the bracket broken and dangling, unhooked it since it wasn't connected o the active set of points and it made no difference. Quote Link to comment
datzenmike Posted March 18, 2013 Report Share Posted March 18, 2013 The condenser reduces arcing and prolongs the life of the points. You can easily run for a short time without them. If in doubt, disconnect all of them. If the problem goes away.... then they are the problem. Quote Link to comment
banzai510(hainz) Posted March 18, 2013 Report Share Posted March 18, 2013 running no condesor is bad. Quote Link to comment
datzenmike Posted March 19, 2013 Report Share Posted March 19, 2013 For sure but just to eliminate it as the cause won't hurt anything. Points will last about 50-150 miles without a condenser. Quote Link to comment
Siempreloco Posted March 19, 2013 Author Report Share Posted March 19, 2013 Hainz, I understand that, but the condenser that was messed up was not hooked up to the running set of points, the set of points that is hooked up has a good (seemingly) condenser. Quote Link to comment
