Subject: Re: Exhaust Manifold Gasket
Hi Folks,
My thoughts on 2 Litre studs - both exhaust and engine water plates.
What a vile job! The studs rust in or simply jam. They are all BSF and may end up needing to be drilled out if they snap. Stud extractors can help but then they can snap as well, the you are in big trouble trying to carefully drill out studs under the camshaft tunnels.
Heat can help.
In the end it might be easier to pull the engine out and do them all upside down. If not, I think you may find it useful to remove the steering box as well as the dynamo.
I seem to recall that we had a discussion about undesirability of stainless steel bolts/studs so perhaps the new studs could be made from bright zinc plated high tensile BSF set screws which seem to be readily available, possibly dipped in Copper-slip grease so they never seize again!
Brass nuts are then good.
I wish you luck and hope there are not to many broken studs and you get to enjoy the car again quickly.
Colin
