SOURCE: I need a picture and spark plug diagram and timing degree setting for a 1987 jeep wrangler with a 4.2 engine

Check this on 1987 Jeep Wrangler 4.2 liter L6 VIN "C" 2-bbl

Ignition timing is a measurement, in degrees of crankshaft rotation, of the point at which each cylinder's spark plug fires. It is normally listed as a specification in degrees before or after Top Dead Center (TDC) of the compression stroke.

On the 4.2L engine, the timing can be adjusted by turning the distributor in the engine. A graduated timing degree scale located on the timing case cover is used for reference when timing the ignition system. A milled index notch in the vibration damper is used to align the No. 1 cylinder ignition position of the crankshaft with the correct timing degree mark on the graduated scale.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

1983 gmc jimmy 350 engine. no sticker in engine compartment. what is timing deg at what rpm ???


12 degrees was common for those engines at 650 rpms, but make sure that the engine is warm and disconnect the vaccum advance, which will probably require plugging the vaccum port at the carb.

What is the timing settings for the 21GJ mitsubishi super saloon. 1983 modle


2 degrees before TDC is the best setting. Slightly more advanced (1 degree or TDC) will work if your gas is really good quality.

Whats the timming for a 1975 jeep cj5 with a straight 6 and a i bbl carb ?


I don't have that info, but whatever the setting was then, it won't apply now as fuel quality is much poorer than it was back then. Therefore, correct setting will likely put you into detonation. Best thing you can do is if it's an automatic, set the timing at TDC, then with the engine running, put it "up against the brake" in gear, increasing rpm. Keep advancing it 'till you hear the engine detonating, then back off two to four degrees. If it's a stick, do the same thing, but just run it up to the top of first gear going down the road and listening for detonation, then backing off timing as I outlined.
Another way of "baselining" your timing is to put a vacuum gauge and tach on it and advancing to the highest vacuum and rpm, then backing off a few degrees. Once you have established what the engine will "like" with todays fuel, use that timing setting for future reference. One note...If it "rumps over" when you try to start it hot, take a couple of more degrees out of it.
What I have outlined is "power timing" which isn't a new thing. Timing on every engine is not the same even the same size in the same vehicle.
The numbers given by the factory are not written in stone, they are just a baseline for experimentation. The important thing is to get the most power without going into detonation while still avoiding hard starting.
Today, computers do that for you.

I have a 82 Jeep Cherokee With the inline 6 and according to the factory oil pressure gauge i have no oil pressure when idling. I have replaced the sending unit and the pump with a high volume pump with no...


It would be cam bearings not main bearings, check with a manual guage first, if you had no oil pressure your enging would be making metal to metal knocking noises and then seize up... Suggestion at the time you remove a oil galley plug with engine off, then disconnect coil wire from ign so engine will not start then have someone help bump the starter and crank engine over while you watch for oil flow from engine block... Check flow then insert manual oil pressure guage...

TIMING ON OVERHAULED ENGINE


if you overhauled the engine and replaced the timing chain & gears, as long as you installed them properly and have installed the ign wires in the right places, the distributor is "locked in place" and is non adjustable (unless you are me, but that's another story) Computer makes all timing changes.
