car wont ideal compression low in two cylinders what could be wroung

Answer
If the 2 cylinders that have low compression are next to eachother.. then the headgasket is blown between cylinders. If they are on opposite sides of the engine or not touching eachother, then you would look into buildup on valves or rings... Check the spark plugs and see if they have oily residue on them, or look burned in this case.
To g o into ANY more detail than that, though, I will need to know the year, model, engine size... and the 2 cylinders that have low compression. I can also (most likely) provide instructions for the repair, if needed.
Just let me know if you need anything else!
