I complete VRS kit - Genuine Parts - GASKET SEAL - Engine top overhaul.
It consists of:
head cover to head x1
cylinder head x1
inlet manifold x2
exhaust manifold x1
water manifold x2
for the above $250 plus postage all wrapped in a nice Isuzu Box

These are geninue isuzu parts and are a little expensive but there is nothing like ISUZU GENUINE PARTS.
I do have 1 GENUINE seperate cylinder head gasket $130 plus postage.
btw - sump gaskets are no longer a stocked item.
