As far as I know, timing is "fixed" and cannot be adjusted on that one. To verify see if your distributor has an integral holddown not a seperate piece as you would find on an adjustable one.

Timing on a 1986 Pontiac Parisienne


It depends on which distributor you have. If you have one with a vacuum line going to it, simply remove the line from the distributor and plug it off so it won't leak. start the engine and time it the conventional way with a timing light hooked to #1 cylinder wire, which is the front one on the driver's side.

If you have the HEI set-up, with the coil in the top of the distrbutor, then connect a Tach to the TACH terminal on the distributor and the other lead to battery negative, UNLESS the instructions for the tach you are usung specify different. Some tachs will specify Tach term inal and battery Positive.

I have a 1986 jeep comanche with a 2.5 liter engine I have an on going problem that will not go away . It will not run steady or smoothly a slow speeds ? I replaced map censer and EGR valve new electronic...


Check the spring tension on the advance weights in the distributor. May be weak or the pivots may be sticking. Best way to test is with a timing light. See if the timing advances and returns correctly

Jeep block casting code 53008403


what are you doing> , buying a bare block?

http://en.wikipedia.org/wiki/AMC_straight-4_engine



what does FIT mean.

to the mounts, the transmission, all will

pass smog

be legal, say in CALIF? (strict year codes there.... btw)

make EFI happy (fit)

just the block, short block or just a naked block. you never said./

key fact on bell housing

Instead of the standard AMC bell housing bolt pattern, AMC/Jeep engineers adopted the General Motors small V6 and four-cylinder bolt pattern



short answer, all years fit, the short block.



In 1986 the head went under a minor revision, the head bolts were increased from 7/16 to 1/2 inch.

id bet that be lowest year.



http://www.allpar.com/mopar/amc-25.html

never on ebay. avoid them for facts.

Timing proceedure 1986 ford mustang 5.0


To set the ignition timing on 86 mustang, get a white crandon or white paint. Find dampener on the crankshaft behind the serpentine bell. Between to 0 and the 20 there is a 10 mark. Use the white crandon or paint to mark this. Hookup your timing light, to the battery and to cylinder number one on the distributor. On this side of the distributor where the wiring harness goes in there are two more wires hanging down from the harness. This is your spout plug connector. Remove it because with this in the computer will keep adjusting the timing by itself and you will not be able to set the timing. So with the spout connector removed and the engine warmed up adjust the timing with the engine running and the timing light pointed at the dampener aligned the pointer up with the number 10 that you have marked. Do this by turning the distributor back and forth until you achieve the correct timing. To do this you must loose and the half inch bolt on the distributor hold down, when you're done retighten this bolt. Good luck.

Set timiing


You have a "locked" distributor. There is no adjustment. All timing "decisions" are made by the computer after reading the info from the sensors on the engine. Ones that influence timing most are the throttle position sensor and Manifold air pressure (MAP) sensor, though all play a part.

1986 Ford LTD 5.0 engine; Failed HC emissions. Did tune up, new air filter,oil change. 2 bottles of HEAT and 1 bottle of Guarantee to pass. HC came back 2.90 passing is 2.50. What could it be.


Heat is pretty much methanol...it will counteract the effects of the other additive you used. Run that stuff out of there and try using 3oz of acetone per 10 gals of fuel and possibly adding a couple of degrees more advance to the timing. If you know anyone with a gas analyzer, perhaps they can help you get it set up.
