I am doing a head gasket job on a 2001 S80 T6 and the previous owner must have had a camshaft seal leak, so he goobered up the metal plug with some sort of blue sealant on the driver side of the head to fix it. When i removed the plug I bent it and I cannot locate the replacement part.

The metal plug is located on the intake camshaft, drivers side. It is installed where the Volvo camshaft locking tool is placed.

Also, previous owner said it overheated and blew the headgasket, but the waterpump looks good, thermostat was deleted by previous owner. Any ideas on why it would have overheated?

 

Why not go to the dealer?

As for the overheating, the radiator could be bad.

 

Yes that's it! Thanks.

As for the overheating, I have to put it back together still to diagnose that. I am waiting on a valve spring compressor from the snap on guy and then I still have to straighten the head and lap valves.

 

I bought one on e-bay for like $5.00 free shipping. Had it in three days...
