Im planning on changing head gasket this w/end as it is blown. Has anyone done this recently? Just trying to get a bit of info before I start it.

So far I have headgasket, timing belt and water pump.

Any other parts I have missed out on.

Any tips/tricks that anyone knows of, anything I should look out for?

Thanks.

Ben

You don't really need timing belt and water pump, unless they are due for replacement. They don't have to come off to get the head off.

You'll probably need manifold gaskets.

While the head is off, check the condition of the welsh plugs, and replace if necessary (Repco have them).

Lots of bandaids for skinned knuckles !!

pull the head off and if you have any probs with timing pm me and i'll help you.

headbolts tension .tighten to 29 nm then to 98 nmthen loosen them , tighten to 25-34 nm then 93 - 103 nm .

make sure you line up all the timing marks with the marks on the belt ( use a new one ).make sure you insall the tensioner pulley washers and spring as they come off . when u insall the timing belt to adjust the tension rotate crank clockwise 2 turns with tensioner instalation bolt loose then use alen key and tighten the instalaton bolt 43-58 nm .dont overtighten case they are known to break .

you will need 27 mm socket and a gear puller to pull the crank pulley off . it will be very tight 150 nm undo it say 10 mm then put the gear puller and it will come then u undo the bolt .

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
