How much does it cost to fix low compression in my car?
My Jeep’s engine keeps backfiring when I start it up. My friend who is a mechanic told me it’s probably a compression issue. I’m not handy at all, so I’ll need to get a professional to fix this. How much will it cost to fix low compression in my car?

Ugh—engine troubles are never fun. There are many potential culprits for low compression, but you can expect to spend between $100 to $200 to fix low compression.
Your costs at the mechanic are for both the labor hours and any parts they need to fix your car. In this case, an issue with the compression means a part of your engine will need to be replaced. How much the repair costs will be determined by what part needs replacing.
Low compression is caused by an issue with a piston, a valve, or the head gasket. Piston or valve repairs should only cost $100 to $200. However, replacing the head gasket will be much pricer—likely $1000 to $2000.
The only way to find out how much you’ll be paying is to bring your car to a mechanic. It’s best not to wait—these issues can cause further damage to your engine, leading to pricier repairs down the road.
