is this ok to do it has around 100k miles on it i was wondering if i could dump some diesel in the valve cover with the oil drain plug undone to flush everything out. can i do this if so how much do i use. ill only do it once so im not really worried about messing up the gaskets unless you think it will really harm them

 

o well i already did it i dumped about 2 quarts of diesel with the drain plug and oil drain plug off then followed it with a quart of fresh oil. then put the drain plug back in and new oil filter and added 5 quarts.

today was basically a day to completly clean out the motor as much as possible. i ran sea foam in the intake twice, sprayed carb cleaner in the intake with it running, i also ran about a cup of water in the intake too with it running, my auto tech teacher told me the steam it creats helps clean and break up carbon build up then added some sea foam to the gas tank and added some to the oil. i also cleaned the fuel injectors by soaking them in mineral spirits in a sonic bath cleaner and blew out my fuel line and put in new ngk platnum plugs, replaced the pvc valve and changed the oil and flushed it al with diesel.

 

You were really into flushing out your car weren't you...I'll pay you $29.50 to do the same thing to my car

 

I'm next in line.

 

i can tell ya it seems a little smother at idle but that could just be the new plugs. but i can tell that the injectors are quieter now you could hear them clicking b4 with the hood up.now you cant

 

Ya so when you do mine it will sound the same right?

 

You did everything right except waste your money on platinum plugs. No added benefit on the neon because of it's waste spark ignition system.

 

whats a waste spark ignition system? and even the cold iridiums wouldnt be a benefit either?

 

The spark plugs are fired directly from the coils. The spark timing is controlled by an Ignition Control Unit (ICU) and the Engine Control Unit (ECU). The distributorless ignition system may have one coil per cylinder, or one coil for each pair of cylinders.

Some popular systems use one ignition coil per two cylinders. This type of system is often known as the waste spark distribution method. In this system, each cylinder is paired with the cylinder opposite it in the firing order (usually 1-4, 2-3 on 4-cylinder engines or 1-4, 2-5, 3-6 on V6 engines). The ends of each coil secondary leads are attached to spark plugs for the paired opposites. These two plugs are on companion cylinders, cylinders that are at Top Dead Center (TDC) at the same time. But, they are paired opposites, because they are always at opposing ends of the 4 stroke engine cycle. When one is at TDC of the compression stroke, the other is at TDC of the exhaust stroke. The one that is on compression is said to be the event cylinder and one on the exhaust stroke, the waste cylinder. When the coil discharges, both plugs fire at the same time to complete the series circuit.

Since the polarity of the primary and the secondary windings are fixed, one plug always fires in a forward direction and the other in reverse. This is different than a conventional system firing all plugs the same direction each time. Because of the demand for additional energy; the coil design, saturation time and primary current flow are also different. This redesign of the system allows higher energy to be available from the distributorless coils, greater than 40 kilovolts at all rpm ranges.

The Direct Ignition System (DIS) uses either a magnetic crankshaft sensor, camshaft position sensor, or both, to determine crankshaft position and engine speed. This signal is sent to the ignition control module or engine control module which then energizes the appropriate coil.

The advantages of no distributor, in theory, is:

* No timing adjustments
* No distributor cap and rotor
* No moving parts to wear out
* No distributor to accumulate moisture and cause starting problems
* No distributor to drive thus providing less engine drag

The major components of a distributorless ignition are:

* ECU or Engine Control Unit
* ICU or Ignition Control Unit
* Magnetic Triggering Device such as the Crankshaft Position Sensor and the Camshaft Position Sensor
* Coil Packs
