Technical Head gasket blown, balancing options, little money

oney re machining it, if it's within spec, they pull down just fine
Steam from the engine isn't normally caused by the head gasket, it's probably leaking somewhere,

Need identifying first, it will have the plastic thermostat housing which regularly fails

9 times out 10 you will just need a gasket set and cylinder head bolts

Warping isn't normally an issue

2011 pain in the neck getting the correct kit, you need the rubber o rings for the oil galleries
Wanted to ask really quick -- is it required to change rings fro oil galleries?
 
Yes

If your talking about the ones in the valve cover

It's what connects the VVT and oil galleries

Id only change the camshaft if they were leaking

They will be quite hard and flattened, they just pick out with something sharp

Id change the valve seals only if there's blue smoke on startup, and had the correct tool

I'm really sorry I feel like it's right in front of me, but I can't find the procedure for replacing these fro the galleries
 
Explained in link below

Just saw this -- thank youuuu

You will find some o rings like this

This is a good example of how they squish flat

You just stab it with something sharp and they lift out

Getting everything clean takes the time, I used carb or brake cleaner whichever was cheapest at the time
 
Hi all! I’m currently working on tearing my engine apart – – just about ready to take the cam cover off, but it won’t budge and I’ve taken all the cam cover bolts out - any suggestions?
 
Does it feel wobbly, if you give it a gentle tap

Or is it solid

It maybe stuck down with gasket sealant

You still have to be careful as they are easy to damage, Something like a plastic ice scraper may help

Well done, getting the engine mount off is normally the worst bit

Thank you so much – – and I’m trying to be careful – – I wrapped a hammer and a rag and tried giving it gentle taps, I also tried using a plastic razor blade where the gasket lining is

From memory there's only 8 bolt

Can you wiggle 1 with pliers

Put a block of wood under 2 and give it a firm tap, but don't hit it hard

When you undo the bolts

It's a good idea to undo them in the reverse order to which they are tightened

10,9,8.........

Also undo them progressively each bolt a bit at a time

If you haven't drained the coolant yet, it's easier to just syphon a bit out, without undoing anything
And, for those less experienced among us who may be reading this, NEVER slacken head bolts until an engine is completely cold - ie. leave overnight before tackling. Undoing them when the whole engine is not cold is a good way to encourage the head to warp, especially if it's an alloy one - as most are now a days.
 
Hard to tell in photo

To me it looks a bit red from a coolant leak (possibly) here

Could be just pushing out the cap, but the top of the exhaust manifold should be under the heat shield if fitted

Pin hole in the tube between the two arrows are not unknown
