Hell bells

!! where to look first

!?

Yours is a rev 3/4 head on a rev 2

?

It is

Whats sort of head gasket you running

??
Standard rev 3

I know the rev 3 has come sort of cavitation in comparison to the rev 2 head for coolant.

.

.

did you use a rev 2 destined gasket or a rev 3

??
Didn't alter it at all

I understnad you've probably addressed all avenues, but its often the simplest one overlooked.

I know when i've stuck a rev 3 gasket onto a rev 1/2, I've had to drill additional holes into it to allow circulation of coolant into the outter regions of the valve

/ combustion area of the head

- always been paranoid in shifting stagnant coolant pockets

!

This is only the HG being address here, were the holes for the coolant passages are in the right place

? and are they big enough.

Seem to remember there were a couple of small holes in the gasket that didn't match the block??

I know the rev 3/4 head has an extension to the swirl pot

( sensor stalk

/ what ever you want to call it

) in comparison to the rev 1/2's

.

.

.

this channel looks like its directly to the area in discussion of the head which may provide that additional coolant flow out of the head

??? or did you use your rev 2 one and block the hole up

???
Managed to use a rev3

I know you've spent forever bleeding it

! What sort of rad cap you got on it

?? not tried fitting one of those 1.2 bar caps on it as a trail

??
As Dino said its a TRD 1.5

hhhmmmm

ponder time
At the mo i am trying to get to the water pump to check it, strugling to get the crank pulley off.

Have you seen the video Neil shot, you can see the coolant shoot out?
Thanks J
