You might need to grab it with some vice grips. There is only one location, above the oil filter on the front of the block, where the timing cover parting line is.
Man.... I’ve been trying everyday for the odd week I think I’ve bough my and returned every tool that I thought could work lol I must be misunderstood I was thing that there access for just the oil fitting on the back of the motor and the this pic was it. Sorry
That isn't something easily done. Access to the back of the motor requires transmission and flex plate removal. Then you have to remove the galley plug. There is no reason you can't get the sender out. It's a sender for the oil light, correct? Grab it with some locking pliers.
The later Of the 2 is what I was referring to but like u said before us still have to remove a lot, if I can’t get it off looks like I’ll be stuck with just the lite for me oil pressure awareness lol thanks again Larry
hi Larry and everyone else . . I know you must be burned out on this subject by now . this thread is very interesting and helpful and ive learned a lot . can I ask about the thermovaccum ? I wish to have both electric gauge and factory idiot light . do I simply remove it and drop my sender for my electric aftermarket gauge in its place . then have just have one vacuum line from the carb to the vacuum advance on the HEI? the reason I ask is that reading this thread I understand I cant just use the hole where the factory temp light sender is now and have both gauge and idiot light wires coming off that right ? (each of the idiot light and gauge need their own sender is how I understand it) . also why I ask is that I have 2 wires going to my thermovaccum and no idea what they are for ? my car is a 72 Electra 455 . vacuum pump removed and HEI added . thanks
That is the Thermo vacuum switch/solenoid for the TCS, Transmission Controlled Spark Advance. Eliminate it. All you need is one vacuum line from the carburetor to the vacuum advance canister. You can use ported or manifold vacuum, your choice. Yes, the idiot light sender cannot be used for your gauge. Use the hole for the TVS for your electric gauge.
so disconnect the two wire connecter from Thermo vacuum switch . pics hopefully show what I have hooked up now regarding vacuum lines . one line from the tvs tees to the carb and that thing at the rear of the manifold on top of the trans (last pic) do I just plug that ?
I don't know what that is at the back of the motor. Never saw that before. Do you know the difference between manifold and ported vacuum?
no I don't know the difference . trying to get a better pic but really dark . goes into this on the firewall that goes in to this canister . im kicking myself for forgetting my shop manual at home that I bet describes what it is .
if it needs vacuum I guess I could tee off from the line going from the carb to the vac on the HEI ? hard to decide when I don't know what it is
The black canister on the firewall is a vacuum storage container for the climate control. It should get one larger vacuum line (Manifold vacuum) from the back of the carburetor. A smaller vacuum line should go from that container back into the dash through that grommet in the firewall. Vacuum moves the various doors to switch between Hot/Cold, Vent/HTR/DEF/A/C/REC. Mainfold vacuum comes from a source BELOW the throttle plates. Anytime the engine is running, there is vacuum at a manifold port. Ported vacuum comes from a source ABOVE the throttle plates. At closed throttle, there is no vacuum. As the throttle is opened, vacuum increases rapidly.
yes you just described what I have . easy to remember the the manifold vac is below as its nearer the manifold . in my case though you said I could use either one going to the HEI?
Yes, you can use either. The difference will be with manifold vacuum, you will get vacuum advance at idle. With ported vacuum, you will only get vacuum advance off idle, when you step on the gas. At part throttle, there will be no difference. Using manifold vacuum will give you extra timing at idle and that can make the engine run cooler. I've seen guys make a big deal out of vacuum line routing, like there is only one correct way to do it, otherwise the engine won't run right. Not so. Here is the bottom line, the stock air cleaner (if you are using it), needs manifold vacuum. The power brakes, transmission vacuum modulator, vacuum storage container, all need manifold vacuum. The vacuum advance can get ported OR manifold vacuum. Any unused ports on the carburetor should be capped. That's it. The tee in your last diagram only works with manifold vacuum. The climate control vacuum storage container needs manifold vacuum.
ok I think im getting closer to understanding it now . I can use this vacuum line from the carb (to the right of fuel line in pic ) to go to the HEI which can also have a tee to the mystery part at the back of the motor . yes I have stock air cleaner
