Please help- couple of weeks washed car motor and immediately had major motor problems. Dealership called they are not sure what is wrong with the car, they are sure that washing the motor could not cause compression problems in the cylinder. Basically, they want to pull the heads ($600) Monday (5/16/05) to see what is going on. I asked if there could be anything else wrong since pulling the heads is $600. They explained they had pulled the plugs and there was no compression in cylindar 1 therefore there must be a problem w/ the valves or pistons? I am so scared- they said to plan for around $3500 maybe more. I have a 1995 C220- I purchased it used and still owe money and this is my only vehicle. Could it be anything besides something that requires pulling the heads? I have been dealing w/ these guys for a couple of years and they seem honest, but 3500 seems like a lot of money. Also could compression be affected by the timing? thanks for any advice
