What is compression ratio of a trw l2292 piston,it is .030 over

The compression ratio does not depend on the piston, it depends on the application.
Different engines/motors have different compression ratios.
This piston will fit more than one model year and application, so you will want to look it up by "what motor you are fitting it into".
However, this being said, TRW may very well have limits of compression their piston of that number will take.
All pistons are designed to meet certain criteria.
TRW alone might know their limits.
God bless your efforts.

Reset timing on chain for 85 olds cutlass

I used to have one of these...there are 2 top dead centre positions you have to watch for. Top Dead Centre "Compression" and Top Dead Centre "Exhaust".

With the distributor cap on, you will know where number 1 is on the distributer, remove the distributor cap and then turn the motor using the crank...keep turning until you see the rotor pointing to number 1. If the number 1 piston is at TDC then you are good to go with it being at TDC Compression- rotor at 1.
If your rotor is at number 1 but your number 1 piston is down then you need to remove the distributor from the rotor 180 degrees then slide the distributor back into the block carefully...remembering to be careful because your oil pump is run by a shaft which snaps onto the bottom of the distributor.

The car doesn't start good or idle. I changed the timing belt and lined up the marks exactly.

This is a common problem. The marks you are talking about actually line up several times during the cycle of the motor. You need to turn the motor by hand until the number 1 piston is all the way up and the next piston in the firing order is starting it's upward movement, this is Number 1 Top Dead Center. Look at the valves and make sure that both valves on the number one are closed and only the intake valve is open in the next cylinder to fire. That should set the valves to Number 1 TDC. Then align the timing marks and replace the timing belt or chain. This should but you at 0 degrees timed and allow you to be able to adjust the timing as needed to get the motor running smoothly. Good Luck.

Why dose gas come out of tail pipe 2001 .3,3L

It's not possible for liquid gasoline to come out of the tailpipe - however, due to chemical processes that take place inside the engine and in the exhaust system which are too in-depth to explain here, it is very common for water to come out of the tail pipe - especially on cooler more humid days.

My 1984 F-150, inline six, is missing badly. I thought I might have mixed up the wire sequence. I checked the order in the manual and the sequence was different than on my engine. When I switched the...

find your firing order, it may be something like 153624
take the dizzy cap off and rotate the motor to see what direction the rotor turns(it should be clockwise)
now remove the number 1 spark plug and bring the piston up to top dead centre on the compression stroke, to do this put your thumb or finger over the plug hole and rotate the motor by hand, when you feel pressure on your finger the motor is pushing the piston up in that cylinder, if you poke a screwdriver down in the hole you will feel the piston coming up. when it reaches the top and the screwdriver is not coming up any more the piston should be on top dead centre.
have a look at the rotor to see where the brass pointer is poing to on the distributor body, mark the side of the distributor housing and sit the cap on to see which plug lead lines up with that point, that will be number one piston firing position.
if the rotor was turning clock wise the number 5 plug lead would go to that terminal, if the firing order is the same as the one that I have told you then continue on until you have the 6 leads in the right order.
usually the pistons run from front to back like 123456
for an inline 6 cylinder
hope this has helped

Set timing mazda mpv 1993 3litre 6v

It will be the same as most other motors. Disconnect the belt from the harmonic balancer and turn it til you see a mark (it will be a divit or lines) and line it up with the ones that are right above it. When you do this it will be 50/50 shot that the number one piston is top dead center. There should be the number of the pistons on the intake. Or you can call auto parts store and get the firing order. One more thing that you need to check is that the rotor under the distributor is pointing at the plug wire that goes to the number one piston. Those three things all lined up will do it.

I relaced my distributor. brought piston 1 to tdc and rotor button on no.1. now the motor almost starts but doesn't and smells of raw gas.

Did you bring the number one cylilnder to TDC on the compression stroke? It sounds like you may have put it on TDC on the exhaust stroke?
