No, quite the opposite- the idea of gaskets is to ensure that an engine gives HIGH compression.
If your car has just had a cylinder head gasket change and you are STILL getting low compression, then this suggests that the problem lies with the cylinder head itself- it may be cracked. Unfortunately there's no effective repair for this, the only solution is to get a new cylinder head I'm afraid.
To reduce compression in an internal combustion engine you should change the standard pistons for a more flatter piston, which will increase the combustion chamber size, some people also change the standard head gasket for a slightly thicker one.
There are several possible indications of a blown head gasket: If the head gasket is blown between adjacent cylinders there will be poor or no compression in either cylinder. Poor compression in any cylinder can be caused by a blown head gasket. That condition can also be caused by a burned valve or piston. Coolant in the crank case can be caused by a blown head gasket. Compression in the coolant can be caused by a blown head gasket. An engine with a blown head gasket usually loses performance and runs poorly or not at all.
it depends on your head gasket. a d16y8 head gasket will work best for giving you the highest compression. as for the compression ratio.. i do not know. i would not worry about it since the power out put will be approximate to that of a d16z6 give or take a few hp.
Have a compression test run on the engine.
Do a compression test.
You can change the head gasket by removing the valve cover. Remove the gasket and clean the gasket surface. Put the new head gasket on the cleaned surface.
Your piston rings may be bad. Do a compression test to find out.
A compression test will verify if the head gasket if blown or not, the majority of the time.
How to change head gasket on a harley sportster motorcycle?
Your head gasket choice should be based on the type of heads and compression ratio you are using. Contact technical assistance at a parts supplier or parts manufacturer for your specific application.
No compression could mean a blown head gasket, cracked head or cylinder.
Most of the times when you have low compression on one cylinder it's an indication that the head gasket is blown. If more than one cylinder has low compression and is hard to start the you most deffinatly have a blown head gasket
