Re: More newbie Q\'s... Freeze Plug, Temp Ctrl vacuum
Hate to reply to my own questions with more questions... but I have to ask this. Usually when I hear about someone wanting to rip off all their emission controls to make their engine prettier or make the car/truck go .001 mph faster... I think to myself, "The stuff is there for a reason- leave it be". Well, here I am now, the guy asking the question. It's a 1986 305, 4bbl ECM, 700 trans, vac diagram code "YDR". The truck is twenty years old. How necessary really IS all this vacuum stuff? Wondering what the odds are that any of it still works anyways. I guess what I'm looking for here is for someone to say "I ripped all my stuff off and it runs fine".
I dunno. Looks like most of my stuff is THERE, but some of it is cut, some is plugged, some is bypassed, and I have (estimating) probably about 5 or 6 hose ends just left open and ignored.
I'm thinking to myself, from past experience, that the most important vacuum line is the distributor advance to ported vacuum so I get advance during acceleration (which it already is... that's one of the lines where someone just ignored the whole vacuum diagram). If I rip all this other stuff off am I going to regret it? There are two parts that I don't recognize or understand, and don't know how wise it would be to unplug. And that's assuming they even ARE plugged in correctly.... "TRANS CONV VAC SW" (a who?) and a "TIP IN VAC SW" (a what)? Those sound important. I don't very much understand the 700R4 trans, but I thought most all of the actual controls were via the TV cable. No clue what a "TRANS CONV VAC SW" does.
Maybe I just need to take a break and take the rest of the weekend off from this thing... would love any input... even if it's "you're stupid- don't do it".
