Re: Cylinder compression 150 per cylinder good?
Thanks for the informative reply Steve. I have tried the water method once
and cannot be sure of the results. I'm looking at a product called BG 44K
which is reported to have excellent results in cleaning injectors, carbon,
etc.
Thanks,
Bill

Re: Cylinder compression 150 per cylinder good?
You will not clean the injectors by pouring stuff down the intake manifold.
If you pour into the intake manifold slow enough to not stall the motor,
there is no danger of hydro-locking the motor. As for the injectors, you
will clean the very tips of them with this method, but this is not what they
do when they talk about injector cleaning. To clean the inside of an
injector, you have to introduce the cleaner into the fuel supply somewhere.

Re: Cylinder compression 150 per cylinder good?
But, that stuff will not change your compression. Your injectors are new,
and I assume they are clean. Your compression is high, but within reason.
You can forget about this "problem" and move on to other things.

Re: Cylinder compression 150 per cylinder good?
But, that stuff will not change your compression. Your injectors are new,
and I assume they are clean. Your compression is high, but within reason.
You can forget about this "problem" and move on to other things.
