Hi,
I'm doing my first head gasket job on a LR. I blew the head gasket in my IIa 88. Ordered replacement gasket set STC1567. Before I begin re-assembly I have a concern that the coolant passages in the block and head don't quite match the gasket. I am wondering if this is by-design and I can proceed, or if I have the wrong gasket. The engine is a very late 2.25l - head is marked HRC 1303 and block ERG 4940. The mismatch is at the coolant passages at the rear right of the engine. The gasket has quite small openings for 2 of the passages, and 1 passages is completely blocked by the gasket.
Does anyone know off hand if this is normal and by-design ( to perhaps restrict coolant flow to the back of the engine ?), or do I need to get a different head gasket ?
UPDATE: Engine serial# is 11H03511 - 2.25l from an early 1980's Defender 90.
Thankyou,
Bep
