Since I've re-built the engine, the car has developed a reasonable oil leak from the HG. Its coming from the drivers side end where the timing chain and is weeping out once the engine gets warm.
My understanding this the area in the block/head is at atmospheric pressure so the oil is coming out by being splashed on the wall and running down but if it is as atmospheric pressure I'm amazed its leaking out.
The bolts holding the outside of the head down are only 6mm so its difficult to put any torque on them without ruining the block's thread. At the meet last night I was chatting to Andy Chan who has a similar problem (but to a much lesser) degeree and he said this problem is quite common.
I'm wondering if the Metal HG needs more compression than a standard HG and its not possible to torque up the bolts sufficiently to stop the weeping.
I did some more remedial work over the weekend and haven't yet had the chance to see if it was successful but my next step is to lift the engine on that side, remove the thread and use a nut and bolt.
Anyone else any similar experiences or solutions?
Cheers,
Jim.
