2.5L and 4.0L ENGINE NOT ROTATED 1. Clean the mounting area of the cylinder block and install a new distributor mounting gasket. On some models there is a fork on the distributor housing. The slot in the fork aligns with the distributor hold-down bolt hole in the engine block. The distributor is correctly installed when the rotor is correctly positioned and the slot is aligned with the hold-down bolt hole. On these computer controlled distributors, initial ignition timing is not adjustable. 2. Align the rotor tip with the scribe mark on the distributor housing during removal, then turn the rotor approximately 1/8 turn counterclockwise past the scribe mark. 3. Slide the distributor shaft down into the engine. It may be necessary to move the rotor and shaft slightly to engage the distributor shaft with the oil pump slot. Align the scribe mark on the distributor housing with the mark on the cylinder block. Ensure that the distributor is fully seated against the cylinder block. It may be necessary to slightly rotate (bump) the engine while applying light downward force to fully engage the distributor shaft with the oil pump drive gear shaft. 4. Install the distributor shaft hold-down and bolt. Tighten the bolt to 17 ft. lbs. (23 Nm). 5. Install distributor cap and ignition wires. Insure that the wires are routed correctly before attempting to start engine. ENGINE ROTATED 1. Rotate the engine until the No.1 piston is at TDC compression. 2. Using a flat-bladed screwdriver, in the distributor hole, rotate the oil pump gear so that the slot in the oil pump shaft is in the correct position (see illustration). 3. With the distributor cap removed, install the distributor so that the rotor is positioned correctly (see illustration). Insure that the distributor is fully seated against the cylinder block. If not, remove the distributor and perform the entire procedure again. 4. Tighten the hold-down bolt. 5. Install distributor cap and ignition wires. Insure that the wires are routed correctly before attempting to start engine.

how do i set the timing for a chevy 350 small block?
I'd just set it by ear and how easy it starts once it's set.
You have to degree the motor, with a degreeing wheel, which requires a major teardown, unless it is on the stand.
was just checking myself, but to give you an idea mine is 12 deg btdc.
attach a timing gun to your battery and number one spark plug wire, mark the timing marks on the front harmonic balancer and engine block and use the gun to set the timing to factory specs by loosening and rotating the distributor left or right.
If your talking about the plug for the block heater, it's located in front of the battery.
where are timing marks on a 4.3l on the block
timing for 302 small blockthere is two small marks on the two timing weels line them up and your good to go
they are located on either side of the block
You don't set timing on a carburator or are you asking the timing on the motor
were dos the dots need to be on the timing chain together or apart
hook up a timing light and loosen dist. hold down bolt, located at the base of the distributor. start engine and warm up aim timing light at timing marks located on driver side of timing chain cover. rotate dist. until timing mark is aligned with correct degree mark on timing chain cover. tighten hold down bolt and check to make sure timing has not jumped
no you need timing tools put a timing pin in the block to lock the crankshaft and use the timing tool to lock the cams
Everything is different in that motor.
Yes, jeep has used the same 6 cylinder engine for many years
on the camshaft pulley there are six notches located on the inside lip closest to the block. there is a 2in pin at the 1 o'clock position when viewed from the front. each notch is a certain degree I have yet to verify.
above crank pulley at the split oe motor block
Approximately 5 degrees before top dead center if the motor isn't set up for high performance.
the timing mark is an engraved line on the flywheel. there should be a metal flap offset of the flywheel with markings for A (advanced), O (ontime), and R (retarded). use a timing light connected to the spark plug wire for #1 cylinder. That is how it is in my 65 impala 327 Minor correction is that the timing mark is on the front damper not the flywheel.
line up timing marks from harmonic balancer and timing tab on timing cover
timing cover, it bolts to the block and covers the timing chain and gears, then the water pump bolts to it.
