Oil leak advice??
Bryanj:
Sorry have to disagree with oddjob as oiled threads need a totaly different torque. BUT you must make sure that the threads on nut and stud are perfectly clean so the nuts run freely and the thick washers are under them.
Honda never recommended a retorque in any manual and normaly a leak that quick would be a bad or displaced "O" ring
Bryanj:
The only one i remember moly being quoted for was the GL100 main bearing bolts but i do agree on the free running nuts. Now I am in the heavy world things like wheel nuts on HGV are specified dry but they do go up to a heavy torque

I've recently rebuilt the engine and been on the road for 200 miles but seem to have got an oil leak from the head gasket. I don't think it's the pucks as the oil only appears on the fin below the head gasket but I will check the pucks by lifting the rocker cover. I'm thinking three options.
1. A slight tweak of the head bolts, risky I know but an easy option.
2. Lift the head and replace head gasket and o rings however it s a new one only 200 miles ago.
3. Lift head, skim head taking minimum off and replace with new gasket and o rings.
Your thoughts would be great fully received. Thanks in advance.
Are they ORIGINAL GASKETS? I think is a MUST use ORIGINAL GASKETS, O,RINGS, or VERY GOOD QUALITY BRAND......

Never ever had a problem with Vesrah in the 70's/80's and you are right about the GL headbolts but i don't remember that being in the original book when i had to rebuild one in 76 for a n idioy customer

I also use Vesrah and I have not oil leaks problem at the moment on my CB550 K3 rebuild engine. I skim head engine for peace of mind and use Edelbrock Gasgacinch for the Engine Head Gasket. re-torque the Engine Head bolts does not work, I think that when there is oil leaks, the only solution is take off the engine head, skim head, change the o,rings(both) and use new gasket head engine(good quality or Original).
Now I am working on my 400 Four that has oil leaks also, 400 km after rebuild engine and the oil leaks show on the corner of the engine head, I used cheaper gaskets and o´rings and that is the problem, I check that the measure of the o´rings are different that the originals..... Again I will skim head, Gasgacinch on the Engine Head Gasket, NEW ORGINALS O´rings and Gaskets and pray.................
Sorry for my English....
