Head gasket replacement in your Detroit Diesel or Cummins engine is considered to be one of the most challenging jobs. Most people probably want to know how to fix a blown head gasket without replacing it. Unfortunately, for these models of engines, this is only possible if you’ve caught the signs of a blown head gasket very early on. Check out the signs of a blown head gasket here. If you have, you can apply a quality sealer to stop leaks. If the head gasket is too far gone, you’re more than likely going to need to start thinking about replacing it.
Finding the proper parts for head gasket repair is simple, just select your engine model and you’ll be able to find the right gasket for your head.
While head gasket parts aren’t too expensive, the labor it takes a mechanic to do the job can end up costing thousands. However, it is entirely possible to perform gasket repair yourself – just be sure to always consult your vehicle’s service manual if you’re thinking about taking the job.
We’ve compiled a list of six general tips you can use when replacing the head gasket of your Cummins or Detroit Diesel engine on your own.
- Always mark and index everything on your engine before starting removal.
- Check the cylinder head and block for flatness. You can check your service manual for the exact specifications; if they’re out of line, you’ll have to send them to a machine shop to be repaired.
- Do not use tools that will remove or scratch the metal on the engine block’s deck or mounting surface of the cylinder head. Surface irregularities can cause more issues in the future.
- Clean your bolt or stud holes before putting head bolts back in. Any interference within the threads can throw off your torque readings.
- Never use sealant unless the manufacturer specifically requires you to. Head gaskets that require sealants will come with the proper type, and the service manual will outline where and how much you should put on.
- 6. Always tighten head bolts in the proper sequence and torque as outlined by the service manual. If you don’t, your head gasket will not be installed appropriately and can fail quickly.
