You are working on a 1988 Honda civic lx and the timing belt is broken how do you set the timing for number one cylinder to topd dead center on the compression stroke?

you will have to use the firing order to verify what stroke you are on take your camshaft gear and rotate until you have one cylinders intake and exhaust valves shut your firing order should be 1 3 4 2 with ones valves shut, 3 intake valves should be open if they are not, you are 180 degrees out rotate camshaft one revolution and that should be correct. this should also place the timing marks on the cam shaft gear level with the head and the word up on the back of the timing gear should be at 12 o clock. the rotor should be pointing at the location of number one cylinder on the distributer.

At what position is top dead center on a crate 350?
the piston in cylinder #1 at the top on the compression stroke
What is top dead center on a 1992 Buick road master?
It is when the number one cylinder has reached top dead center on the compression stroke.
Where is top dead center on a 3.8 V6 ford windstar?
That would be the top of the compression stroke on the number one cylinder.
What is TDC for a 1991 Z28 Camaro TPI 305?
The TDC is when the number one cylinder is at the top or top dead center of the compression.
What is the compression psi of a compression ratio of 16.2?
There is no direct connection between compression ratio and pressure. Ratio is a mathematical calculation of the cylinder volume from bottom center to top center. Actual cylinder pressure will depend on the volumetric efficiency of the engine. Factors the affect volumetric efficiency include rpm, intake design, throttle plate size, amount of restriction in the exhaust, size of the valves, shape of piston and combustion chamber.
Does the rotary button have to point to the number 1 cylinder with the number 1 cyl at top dead center on the compression stroke of a dodge 5.2?
Yes
What is top dead center on a 1994 22re?
In the field of automotive repair, we always refer to top dead center as. The #1 cylinder being at the TOP MOST POSITION during its compression stroke. The 22RE is no exception.
What valve will be open when the number one cylinder is at top dead center?
Presumably we are talking 4 stroke? If so, none or the exhaust - it will be at the top of the compression or the exhaust stroke
What does a compression test tell you?
A compression test can tell you many things such as if you're getting blow by. which means one of two things either all the compression ring gaps on the piston line up in sync or possibly you have a crack in your cylinder. Also if you have the distributor shaft apart from the engine a compression test will help indicate when the proper piston is at TDC (top dead center). If you get low compression on one cylinder, put a teaspoon of engine oil down the bore. If the compression improves, then you have a worn bore or rings. If there is no difference, you have a burnt valve. If two adjacent cylinders are low, it is very likely that you have a blown cylinder head gasket between those cylinders. This could also include a warped cylinder head and may need skimming.
When do I put in the distribeter before or after finding top dead center?
You want the TDC on the compression stroke of the #1 cylinder, then drop in the distributor with the rotor pointing to #1 on the distributor cap.
You are losing compression threw your carb on 5hp Briggs do you have valve sticking?
Valve sticking, Burnt or broken valve, or bad valve seat could all be the problem. Be sure to check leakdown compression at 15-20 degrees PAST top dead center! Compression release is still engaged at TDC!
Auto Technician A says the total volume of all the cylinders in an engine is called the compression ratio?
The volume of an engine is called displacement and is typically measured in cubic inches or liters. An eight cylinder engine that could hold 1/2 liter of water (or air) in each cylinder would be a four liter engine. As the pistons move to the top of the cylinder in an exhaust stroke, they theoretically "displace" the 1/2 liter of air in each of the cylinders. The compression ratio is calculated during the compression stroke. If the piston occupies 90% of the enclosed cylinder space when it is at top dead center, the compression ratio is said to be 10 to 1, or 10:1. If the displacement of the cylinder was 10 cubic inches, it would have been compressed to 1 cubic inch.
