A piston without compression in a Chevy 350 engine could be due to a broken or worn piston ring, a damaged cylinder wall, a blown head gasket, or improperly seated valves. Any of these issues can result in loss of compression and affect the engine's performance.
The lack of compression in one cylinder of a Chevy 355 engine could be caused by a number of issues such as a leaking valve, a blown head gasket, a cracked piston, or improper sealing of the piston rings. It is recommended to perform a compression test and further diagnostic tests to identify the exact cause of the low compression in that cylinder.
It is from a 1968 Chevy 327cid
Number one cylinder is located driver's side front of engine. With the # 1 piston at TDC on the compression stroke, the rotor will be pointing at #1 plug on cap.Number one cylinder is located driver's side front of engine. With the # 1 piston at TDC on the compression stroke, the rotor will be pointing at #1 plug on cap.
The number 1 piston on that motor is the first cylinder on the drivers side.
When the # 1 piston is at TDC on the compression stroke, the rotor is pointing to at the # 1 position on the cap. # 1 cylinder is on driver's side, at front of engine.
bent valve, burnt valve, stuck valve, broken piston ring, cracked piston, cracked head, blown head gasket.
Driver side, front.
Crank motor over until number 1 piston is all the way up on compression stroke, the distributor with rotor bug, if installed correctly, will be pointing toward number 1 post.
front right drivers side
closest to the pulley/belt.
