How do you know if your 1967 350 is on compression stoke for piston 1?

You will need a another person to help you do this.
Remove #1 spark plug and get someone to bump the engine over alittle at a time while you hold your finger over the #1 plug hole and as soon as you fill it blowing out compression from under your finger and it stops, Then #1 piston will be at TDC. TOP DEAD CENTER. You may have to bump the engine over a few times to get the feel of it.
When #1 is at TDC then the timing mark on the harmonic balancer will be lined up with zero on the timing tab on cover.

How do you know if a k'x80 piston is blown?
Do a compression test.
Why would a motor loose compression in a 5th cylinder when it is a 6 cylinder?
from what i know there is no difference in what piston loses compression based on the layout. a piston loses compression due to faulty valves/seats/stems or damaged piston rings. if you have low compression problems, check the above, in that order
When the number one cylinder is on its compression stroke is the intake valve open?
The piston is on the up stroke to compress so both valves are closed
Is Port Vale better than Stoke City?
In theory, the answer is no. Even as a Vale fan, I know that the Stoke City are better than us. Stoke are in the premier league and Vale are in League one, However, Stoke is in the Premier League. From these facts, we can tell that Stoke are better than Vale.
Is Alton towers in stoke on Trent?
It's technically is in Stoke-on-Trent, but many people know as it being in the Staffordshire Moorlands.
How do you know if the piston rings in your car are bad?
Worn piston rings will cause your car to burn oil. It will smoke, and you'll have to add oil frequently. Additionally, the performance will fall off as compression is lost past the worn rings. There may be a "slapping" sound as the piston skirts slap the cylinder walls, and this will occur in cases of advanced ring wear.
Is carmount side primary school the best in stoke on Trent?
yes carmount side is the best primary school in stoke on Trent i should know i used to go there
How do you know if the push rods are bent on a 1997 s-10 when the timing chain broke?
Line up the timing marks, install new chain and gears, then do a compression test. If you have some cylinders with no compression, the push rods and maybe some valves are bent. There may be some piston damage done also. Good luck.
How do you know when the motor is TOPDEAD CENTER on a 1992 VW Jetta?
Find the # 1 cylinder. Remove all spark plugs, turn the engine over (BY HAND, DO NOT USE THE STARTER) until the # 1 piston is at the very top on the compression stroke. You now have TDC. Placing your finger over the spark plug hole will tell you when you are on the compression stroke. A long handle screwdriver inserted in the # 1 cylinder, will tell you when the piston is at the top. Caution: Turn the engine by hand, never with the starter.
You did a compression test and have 195lbs what is the compression of the pistions?
There is no possible way to answer that question based on just PSI. Try googling compression ratio calculator. Once opening the first result you will need to enter your engine specifications to find out the answer. You will need to know the bore, stroke, gasket thickness, size of the combustion chamber and specs of the piston head to get an accurate answer. If you have a unmodified engine then it may be easier to search google and wikipedia for your specific engine to find the results.
Are the timing gear marks dot to dot when number 1 piston is up and on the compression stroke on a 1978 350 Chevy?
Usually, but there are some model years where both dots are at the top of the sprockets when #1 is up for compression. You'll know right away when you start adjusting the valves because when you finish #1 and move on to the next it won't adjust right.
What happens if i pull the compression lever in when your bike is running on a 2002 yzF250?
it will slightly open 1 exhaust valve and there is a small chance of piston contact, u will notice this as u will sure hear it or u will drop a valve and boom , u know the rest
