Why not just put a small dab of paint on there instead to mark it?

2.3L gas engine. there is also a diesel.
2.3L 4ZD1

why not say the JOB first.????????

ill give the first 16 instructions then photos
  1. Disconnect the negative battery cable.
  2. Loosen and remove the engine accessory drive belts.
  3. Remove the cooling fan assembly and the water pump pulley.
  4. Drain the fluid from the power steering reservoir.
  5. Unbolt and remove the power steering pump. Unbolt the hydraulic line brackets from the upper timing cover and move the pump out of the work area without disconnecting the hydraulic lines.
  6. Disconnect and remove the starter motor if a flywheel holder (part No. J-38674) is to be used.
  7. Remove the upper timing belt cover.
  8. Rotate the crankshaft to set the engine at TDC/compression for the No. 1 cylinder. The arrow mark on camshaft sprocket aligns with mark on the rear timing cover.
  9. Remove the crankshaft pulley.
  10. Remove the lower timing belt cover.
  11. Verify that the engine is set at TDC/compression for the No. 1 cylinder. The notch on the crankshaft sprocket aligns with the pointer on the oil seal retainer.
  12. Release and remove the tensioner spring to release the timing belt's tension.
  13. Remove the timing belt.
  14. Unbolt the tensioner pulley bracket from the engine's front cover.
  15. If necessary, unbolt and remove the camshaft sprockets. Use a puller to remove the crankshaft pulley if necessary. Don't loose the crankshaft sprocket key.
the marks, now.
the 2.3 and 2.6 engines are sisters

so here are the 2 marks.

Were do.I find the factory marks on my distributor and intake to stab it right, .on my 93 chevy 5.7


I don't know of any factory marks. You have to put the #1 cylinder at TDC of the compression stroke, then drop in the dist. so the rotor points to the #1 spark plug tower on the dist. cap. The rotor will turn slightly as the dist. shaft slides down, so you need to start the dist. with the rotor turned slightly back. When it drops down, the rotor will be pointing directly to the #1 plug wire tower. Repeat until you have it right. Then it will start, and after warmed up, set the timing with a timing light.

TDC (Top Dead Center) of compression stroke: there are two TDC's for each cylinder, the compression TDC, and the exhaust TDC. To find the compression stroke, pull out the #1 spark plug. With your finger over the plug hole to feel pressure, turn the crankshaft over clockwise with a ratchet and socket on the crankshaft pulley. As the piston rises on compression stroke, you will feel pressure on your finger (there is no pressure build-up on the exhaust stroke). As soon as you feel pressure, now just turn the crankshaft further till the piston is at TDC. You can use a straw or pencil in the hole to find the top, or just look at the pointer scale by the crank pulley. The mark or notch on the pulley will be at 0 degrees on the pointer scale, TDC of compression stroke-now drop in the distributor.

I replaced my whole distributer in my 1992 2.8 liter v-6 s-10 but my son washed off the alignment marks, so I was wanderind how i can time it? please help!!!


If you know the engine's number one cylinder location, you need to put it at TDC of the compression stroke, then you lower the distributor in so that the rotor ends up pointing to the #1 spark plug wire tower on the distributor cap. As you drop it down, the gear on the dist. shaft will mesh with another gear and turn slightly. You want it ending up pointing directly to #1. Get it seated, then you can start the engine and set the timing according to specs with a timing light.

To find TDC of the compression stroke (as opposed to TDC of the exhaust stroke), pull the #1 spark plug out. Put a socket and wrench on the crankshaft pulley and turn it in its normal direction (clockwise), with your finger over the spark plug hole. As the number one piston is rising on its compression stroke, you can feel the pressure build up under your finger. You won't feel any pressure as the piston rises on the exhaust stroke, only on the compression stroke. So when you feel pressure, you know the piston is rising on its compression stroke, and you can turn the crank on around until the piston is at top of its travel-the notch on the crank pulley will now line up with the zero degrees mark on the pointer scale beside the pulley. There, TDC of compression stroke. Now drop in the distributor so the rotor tip lines up with the #1 spark plug tower on the dist. cap.

1992 chevy 5.7L 350 8 cylinder engine. I took the distributor shaft off without marking it. How do I know it is in the right position when I replace it?


You have to retime it. You put number one cylinder at top dead center (TDC) of compression stroke, then drop in the distributor so the rotor is pointing to number one tower on the distributor cap.
To find TDC of compression stroke, remove number one spark plug. Use a socket and ratchet on the crank pulley and turn clockwise. Keep a finger over the number one spark plug hole. When turning the crankshaft and you feel pressure against your finger, the number one piston is rising on the compression stroke. Now use the ratchet and turn the crankshaft on around until the crank pulley notch lines up with the zero mark on the pointer scale. Piston will now be at TDC. You can now drop in the distributor. When seated, the rotor must be pointing to the number one cylinder on the dist. cap tower. Dist. shaft will turn as it is seating-if you get it wrong, pull up distributor and reposition the shaft until it drops down into the exact right position. When done, start the engine and use timing light to set the timing to specs.

Regaurding firing order on 1993 chevy G20 350 small block is 1 8 4 3 6 5 7 2 but WHERE does number 1 START? ... clock wise I was told and there is a manifacture raised line between two posts IS THAT WHERE...


Yeah, likely that raised line is your starting point. #1. Try lining up your crankshaft pointer(turn with a socket wrench on crank pulley) to 0 degrees. If you are on compression stroke on cyl. 1, your rotor will be pointing to no. 1 plug tower. If you are on exhaust stroke of no. 1 cyl., then your rotor will be exactly 180 degrees off. If you are confused, just turn your crank clockwise one turn (360), and line up zero again. Now your rotor will be (again) either pointing to No.1 position, or 180 degrees off (pointing in opposite direction)One of those positions should line up with that manuf. mark. (Here is easiest way to find TDC of #1 cyl. on compression stroke: pull #1 plug out. Hold finger or thumb over hole, while turning crank, when you feel pressure building on cyl, you are approaching TDC of compression stroke. Just turn crank (clockwise) till pointer is on zero. Done!) Now your rotor will definitely be pointing to #1 plug on your dist. cap.

I need to know how to set the distributor on a 82 toyota corolla 3tc engine ive already set the piston at top dead center ,, but every time i ste the distributor to align with the number one spark on the...


Most of these vehicles distributor lock in connection at the end of the distributor shaft can only go in one way, the reason why it won't go in at rotor number one terminal position is because you probably have the TDC position 360 degrees out, there are two spots concerning TDC because for every one revolution the camshaft turns the crankshaft turns twice and unless you put you finger into a spark plug hole and turn over the motor to feel compression air being forced out the hole (compression stroke) you will not know for sure that you are at correct timing check point that is TDC compression stroke or otherwise known as TDC firing stroke, In you case just continue to turn the crankshaft pulley until the pulley notch comes around again then drop the distributor in. As I said before the distributors usually can only go in one way but this may be the exception.

How to set timing mark


Timing mark is appearing with number 0 and line marks on the area near the pulley crankshaft.
The crankshaft pulley mark has to be lined up with the cam shaft mark and the piston # 1 has to be on top position providing its intake and exhaust valves in close position. This is called TDC ( top dead center). It sounds complicated to understand, but it is simple to imagine like this: All valves are closed and Piston #1 is up at high position to make a peak compression and a spark ignites to make a compression pushing the piston down to make a stroke. Hope this can help.

Golf fti 8v, 1993 k- reg 2 E engine, Is the engine at tdc?


slide a straw or a pen into the plug hole and slowly rotate crank pully back and forward and note the rise and fall of the straw this will indicate TDC . once TDC is achieved note the mark on the pully should be alighn with a mark on the timming case .rotor button to number one lead will have you on compression stroke .cheers MAL
