hasn't overheated then would the cylinder head need to be skimmed or not
? I have read that an updated head gasket was issued in the early 1990s.
Is this true or not ? Are there any differences in replacement head
gaskets sold by Rover and those sold through motor factors ?
Re: Replacing the head gasket on a Rover K16 engine
Usually dosen't need skimmed but check for corrosion micro pitting on the
head face around the top of the bores.
Rover head gaskets are made by Paynes and sold under both these names and
also Unipart branded ones are also still in circulation - don't use any
other type but these -- latest spec gaskets have stainless steel dowls
To be sure it is a gasket failure before stripping check the manifold gasket
and water pump for leaks, also if the car done 80kmile+ check the rad very
carefully. The work shop manual stripping procedure should be followed
exactly. Bigest problem is likely to rounded hex heads on the inlets
manifold bolts --- best to use a brand new tight fitting 6 point socket.
Head bolts are safe to use if checked carefully following the procedures in
the manual. The inlet manifold gasket and cam roll pins should also be
renewed (latter can be hard to find) as a matter of couse.
Use Loctite when assembling the cam sprokets on to the cam. When filling
with coolant bleed air from the system via the bleed bolt on the raddiator
hose below the distributer cap.
