Head Gasket Replacement Sign In


I've just had the head gasket replaced on my car - just wondering about how to drive it now I have it back - is there a "breaking in" period for a new gasket?

As I only generally do city driving my thinking is that if I drive it softly, then some time in the future go for a blast on the motorway for a couple of hundred miles, it may cause damage? Is it better to drive quite hard (for the first tank of fuel or so after HG replacement) so it gets used to it; or would that be a waste of time/petrol?

Apologies but I don't quite know how it works.

Thanks for any replies.

There is nothing to "break in". The job was either done right or it wasn't. If the head wasn't sent to the machine shop for inspection and resurfacing, it will likely have more problems. If it was done right, then your only concern is not overheating it.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Thanks for your reply. I'm confident the job was done right, I was just wondering if I needed to adapt my driving style at all to wear it in, which you have answered.

Many thanks

Ditto with HT. Some replacements are better than the original. Drive on, no break in for those,

Depending on vehicle and engine they have some where you have to go back and re-torque the head bolts after a certain number of heat cycles.
