Exhaust gases leaking.

[awf]

Hi,

My GZ has been sat in the garage for the best part of a year while other things have been going on…

I have got it up and running again after installation of a new battery, clearing out of an insect nest from the vacuum line and reconnection to the petcock etc. etc. etc.

After starting up and running on idle for a few minutes exhaust gases start to escape from the gasket area where the left hand exhaust pipe connects to the cylinder head and at stopping the exhaust backfires. I'm assuming that the backfiring is caused by the escaping gases prior to the muffler.

What is the best way to seal this leak? I'm wondering whether changing the steel gasket is necessary or an application of a liquid gasket sealant?

Thanks in advance for any pointers!

I too replaced the left side exhaust gasket [while doing this I replaced both sides] I also discovered a small head gasket leak and replaced it also. Runs great, no exhaust noise now. you may want to check the head bolts/gasket just to be sure. terry

Fair point from Terry. Just check your torque settings on the head bolts to make sure they haven't backed out some over time.
