I'm fixing the busted head gasket on my 1100.
It has bolts, not studs, what is the reccomended torque people?
Thanks in advance

Head studs 42 ft/lb, Rocker shafts 26ft/lb........what head gasket are you using Tombo

The recommended thing is to throw the bolts away and fit studs. The bolts were only used for a couple of years and are not very reliable. They usually break shortly after changing a head gasket.

I'm using a monotorque this time. Morris 1100 wrote: The recommended thing is to throw the bolts away and fit studs.

So no one can tell me the recommended torque????

According to the Morris 1300 workshop manual the correct tension for the head bolts is 50lbs/ft. |

Scott did tell you and he is right your theory about clamping pressures is wrong the tension sets the clamping pressure not the type of thread |

Make sure you start a thread about how you should drive the engine just after you get it all running again with the head gasket. And is it a copper head gasket?

And is it a copper head gasket? Ok boys!!... I think we have had ample fun with both these subjects.

Are copper head gaskets superior to other types? |

Have a read ! http://www.goodvibesracing.com/Copper_Gasket_Tech.htm They dont mention it but they have to be annealed to work properly and I,ve been told there is art to doing it properly and that is why most people are happy to use the off the shelf ones. . |

Oh crap,,, is this still going
Alrighty, its my fault that there is al this "banter" about copper head gaskets. There was a thread a while ago, a bunch of people (everyone on here) said they "blow so hell no" and I said I've always used em on my motors with out issue. So after everyone tried to convience me I was mad, and a few experts got involved and tried to tell me I was seeing things I went and started some research (I know I know,, pretty bad bit of OCD there )
Heres what I have found so far; There are 3 main manufactures of copper head gaskets for A series motors, Payen, Rover and I forget the third but if you really want to know I'll find out and put it up. Now at least one of these guys ""claims"" to have a different type of composite... its my bet that I was just lucky enough to be buying them from one of the manufactures that have a combo that works. ***** BUT***** After reading everyones testimony that they "don't work" I personally am not going to risk it anymore and the motors I do from now on I am going to use BK450's... Now there are probably a couple of you out there who knew this but BK450 does not always mean ""metro turbo gasket"" the bastards that make these gaskets thought it would be halarious to use the same part number for multiple products. The standard one which has a 4cc compressed volume and the turbo one has a 3.1cc compressed volume.. Maybe some one can explain that, I don't get it. I thought that the turbo gasket might have held more so that it also had so de compressing capabilities as a posed to jacked the comp ratio up? So there you go... the ""Copper Head Gasket Guy"" doesn't use em any more either
