I really doubt C foam will help you compression unless your rings are completlly gunked, it really just frees up fuel lines, I had a 70's model beater and tossed some Marvel Mystery oil into it, and clean out the oil lines, and it evened out the compression, it worked for a while but not a rebuild in a can - some people are 100% against the mystery oil, so check into before you just do it.
This all depends on why it has low compression. If the rings are worn out, the motor should be rebuilt. If one of the valves is bad, re grinding it or replacing them is the fix. Perform a cylinder leakage test to confirm it. You will probably need to take it to a shop for this, but unfortunately, there usually are no quick fixes for low compression.
Low Compression usually means that the cylinder rings are worn. You should also do a leak down of each cylinder. That will pinpoint which cylinder/s are bad. Also,possible poor seating of valves or improper valve seat contact.
Run a compression test. If only one cylinder has low compression, it's probably a damaged valve or pushrod. If the compression is low in all cylinders the cam is probably not timed correctly.
Primarily the result will be incomplete burn of the mixture or no ignition at all. Reduced compression reduces the particle pressure of the molecules in the cylinder resulting in variations of the burn pattern. This results in uneven pressure build up in the cylinder which manifests itself in a lack of power. Thus drivability of the vehicle is affected.
If it was a head gasket then the compresion would be low in the affected cylinders low compresion as a result of wear wil make the car hard to start and overheating can also lead to electrical problems, Besides blowing a head gasket, overheating can also cause a cylinder head ro crack. Low compression and engine not starting or hard to start are symptoms. As mentioned above, do not discard the possibility of electrical problems due to overheating. However, the prime suspects are blown head gasket and/or cracked cylinder head.
how to fix a cylinder #1 has low compression diagnose on 2.9 chvy colorado 2007
You have to take out the cylinder, how low is it, what is the difference
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
Loss of Power
It should be a high of 185 and a low of 140
A "Bad cylinder" or "dead cylinder" is a cylinder with Low compression psi. Symptoms: rough running low power can cause high oil consumption

A popping sound (when running if it will run), backfiring, and low compression on one cylinder when testing with a compression guage.
If it is causing the cylinder to misfire, yes.
Low compression in one cylinder can mean several things. The valves or piston rings may need to be replaced. There may be a crack on the engine, or the head gasket may have blown. The engine should be diagnosed properly to see what exactly is the cause of the low compression.
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
No. It won't have enough compression to fire the cylinder to burn the fuel and air mixture thus creating a "miss".
