Head gasket "discrepencies" 4th gen GTR

[Vlad]

hey there All,

So first time posting about my 4th Gen GTR ST162 3SGE.. 86

Not terribly long ago I did a compression check on her and found that cyl2 was rather low in compression...

So I went about doing a head gasket.

New vrs kit MLS head gasket .. head was sent away for skimming and checking was pressure tested also..

So she's all back together new head bolts, new hoses timing belt etc..

The ISSUE. I'm loosing water...

but only when i actually drive it{300M down the road} and the water levl drops below the top fins of the radiator......I can sit in the backyard idling for n hr and not loss any water.

there are NO leaks anywhere.

So Its A GTR with a 3SGE in it, has 2 individual rocker covers{2 peice}, no EGR, there is a YAMAHA stamp out{raised} just above the exhaust ports... and the head looks nothing like any of the othe 4 3SGE head i have on spare parts cars. . . also have a huge allen keys looking "welsh plug" between the 2 sets of exhaust ports..

going 2 be pulling her all down again in the nearish future so can and will take any 'requested" pics.

any body have a similar issue? or can anybody shed some light on the situation.

I'm thinking that my blocks got a crack somewhere. .. . . .

Before the head gasket everything was fine the was no water loss the was no mixed fluids..

Just a "flat spot in the engine power that i figured was a compression issue, which "panned out" ..

BUT has made things EXTREMELY worse.

Peace

Cheers

Does it blow white smoke?

Was the cooling system correctly bled when re-assembled?

I'm guessing no machining was done on the block?
