1HDT head gasket replacement

[lankyy]

hi guys im needing to replace my head gasket as it has started to leak oil from below the 6th port on the inlet side from the head gasket

where would be the best place to get gaskets from?

Go genuine ,not after market.

Excuse the basic question, , but was it definitely coming from the head gasket, or was it possibly coming from the rocker cover(further up)?

[mumbls]

mine had oil leaking down onto the block, traced back to the back of the rocker cover, it was a 20yr old gasket, replcaing it fixed the problem

[lankyy]

so the leaking wasn't from the head gasket. it was leaking from the inlet gasket but running down the edge of the head gasket

I would be giving it a big clean to confirm where its coming from.
But oil from the intake area is normal on a TD... Crankcase oil vapour gets plumbed back into the inlet system and puts a light coat of oil all over the inlet manifold on the inside.
With boost pressure coming on it can force oil out any small leaks at gaskets or butterfly bushes....

There ain't no butterfly's on a 1HDT so the bushes won't be leaking.

There ain't no butterfly's on a 1HDT so the bushes won't be leaking.

That depends if it's a nz or Aussie new vs jap import....as to if it has egr/ butterfly set up.

But generally start with the simple or easy stuff rocker cover gasket etc. If it still blows oil out from the new gasket it will be worn rings allowing too much compression into the crank case.
