Now it seema the knocking noise is the new water pump? Not sure. Kind of stumped

Well it all just sucks because while it doesnt overheat now and seems to run fine, its now pouring oil out from between the two halves of the head along the passengers side, plus the weird noise it is making. Was not leaking oil before as had finally gotten oil leaks fixed. The two head halves were gasket gooed as well. So either have done something wrong or used wrong stuff or missed a step or something. Have no idea

Gasket has failed between the two halves of the head. So now have different goo to redo that. The noise unsure but going to make sure injector clearances are perfect.

I'm thinking you've stripped a few bolt hole threads between the head sections by over tightening. You might need some helicoils to fix it. When the leaky gap is gone your tapping may disappear too.

They all torqued up well and correctly so dont think that they are stripped. There is one that had to helicoil. But the gasket had failed between head halves as the goo didnt work. Tried different and seems to be holding. Also made sure bump clearances were perfect and seems to be purring nice now

Pics of the gasket Epic?

The old one? Haha yeah ill find them and post them. The old gasket had not failed as such but head had moved as one dowel sheered other not straight. Only weird thing its doing now is first time use accelerator after start up it doesnt register fast. Reversing today turned aircon on and pushed accelerator and nothing. No revs no movement. Then airon to econ mode and it started to respond. Redid when got home (13kms) and responded to pedal as normal. MAP was cleaned not long ago, MAF replaced last year. Plus disco has tune from TRS. So this has only been this bad since putting it back together. Set injector clearance as per RAVE so not sure if they are slightly out. Or if Trans which is 330000kms old and due for a service is cause. Though wish was cable accelerator not fly by wire stuff.

Two things to look at which may cause those symptoms
Air in fuel , did you replace injector washers ?, was everything spotless when doing them?
The other is retarded cam timing
Does it start first go?

**discorevy** · 18th February 2015, 12:34 AM

you say the gasket failed between the head halves........
Which gasket do you mean?.
Cheers

it starts fine first go, purged fuel system several times. injector washers were replaced and all spotless. im not sure if could be retarded cam timing, followed RAVE proceedure on locking chain/pulley/cams in place. but does not mean it isnt the cause.

it otherwise sounds great and super smooth! just the initial when it is cold and use the pedal it just does not register, very delayed throttle response which seems to then be ok when car is warm.
the gasket was the goo one you have to make with a gasket goo between the cam carrier and the rest of the head. so not a proper gasket per say but one now made using 518 loctite flange sealant

and thus far not leaking.
