Well.....That bit me in the bum!
I made the mistake of commenting on how reliable my KV6 Facelift Hippo has been, and neglected to knock on wood.
Yesterday morning I did my 40km commute to work with no issues and spent a few minutes in the car reading the paper. I was surprised when
I got out and found a large pool of coolant spreading under the engine. The header tank was half empty.
Off came the engine cover and examination with a flashlight showed the engine Vee very wet with coolant. My first thought was it was the
thermostat but it was dry. Checking while running (with the cooling system pressurised) revealed a small jet of water coming from the inner front corner
of the intake manifold where it meets the head.
I did have a go at making it home but after refilling the header tank twice in 10km I parked it. When it had cooled down a bit (just normal cooling, it never overheated).
I had a go at tightening the manifold bolts. The bolts under the manifold are next to impossible to get at with all of the ancillaries in place!
Tightening didn't help so it was tow truck time. That auto club membership finally paid off.
Today I picked up new gaskets, and new O-Rings should be at the dealer on Friday so it looks like it will be a busy weekend.
