i can see 2 with the heat shield on...

Take the bugger off then

If your gonna start without doing compression test......my advice is take the heat shield off and soak the the exhaust manifold studs in whatever......i used wd40..plus gas is also recommended.....just soak em in it....and leave overnight.....you dont want to go snapping any studs of Tunnie.....so easy on un doing them   you might find on turning the copper nuts the studs come out with them.....but thats fine

Seeing as it looks like you are not going to machine the head, does the manifold (and associated risk with studs) need to come off?

If I'm helping with this, I'm not going to take anything for granted. The head will be inspected within an inch of it's life with a straight edge / feeler blade, I would want to be very confident it's OK before refitting. Driving back from brum with a failed HG alone should be ok, providing it's not overheated enough to distort anything.

Personal recommendation would be to replace the manifold gasket and flatten the manifold surfaces, because the 4 pots are known for going. However - it is Tunnie's choice - and also Tunnie's risk (!) - that if any studs do break, then it will be a trip to the machine shop for rethreading!

I'm also not re-fitting a used cambelt kit and / or water pump... that would be daft following that work.

My concern with the head - and it assumes the coolant loss and HG are related - is that the coolant loss was noticed, topped up, then driven to brum and back. Would the coolant start to channel a groove?  Also, apparently there was no heat in cabin, so therefore the temp gauges would work (again, apparently not reading, or reading low), so we don't know how hot it got.

My fear is, I know Tunnie's dad is in a hurry for car back, that you will strip down, find it needs machining, then have to come back again - I know you have no issue with doing this, but I also know how very busy you are, on and off the forum.

Whist I hope you're wrong, I do agree that there is a chance.

Well, if it needs machining, then it'll have to be done! I guess we won't see that, until it's off though. The only way any time could be saved, is if Tunnie wants to get his fingers dirty and remove the head now, and I'll help with re-fitting!

I don't mind either way..

[Taxi_Driver]

no puddles of coolant after its been parked.

Most signs point to head gasket, strong petrol smell in the header tank, but i am too suprised it failed the snifer test.

Just had Jaime around complaining why i had not the head off my dads 2.2 yet, simple fact is I am scared!

To big areas: cam belt removal, and second dropping the exhaust.

Its also the fact its my dads car, if it were mine i'd happily get stuck in. But being my dads, i don't like touching it.

You dont need to take the exhaust off......undo the manifold to cat bolts and the exhaust will stay where it is  

[tunnie]

the best solution would be for me to remove the head first, but i am still not confident in doing this on my dads car. I would do it on mine, but not his.... i don't want to shear something!

AFAIK there was heat in the cabin, and the temp stayed at a constant 85.....

[Craig_R]

For the price of a skim i would do i for peace of mind its only about 30 quid.

If you are iffy about doing your dads car tunnie make sure you tell him the price a garage would charge which is around the £500 mark and if it was VX Bah It could be a million pounds.

As long as you take your time there is not alot that can go wrong its just time consuming but with james helpping out it will be a days work tops for the both of you.

Dont forget when removing the head there is a bracket that gos from the bottom of the intake manifold to the engine block the numpty who did my head gasket snapped this bolt off in the engine block and left the bracket on it took me ages to find out what the ringing noise was when driving it was the bracket tapping against the engine block but the noise was traveling up the bracket (mount) into the throttle body.

Since i cant drill the snapped bolt out i had to remove the bracket (mount) from the intake manifold to the engine block, And i cant go back to the guy who did as it took me 7 months to track it down   and he will just say it had nothing to do with me,

He said it was cold in car (or did I dream that bit?).

You can do it!

Ah....risky shift.

Its ok for somebody else to bugger it but not you!  

You realy need to take that head off and get it skimmed before James comes for the re-fit.

Removal is not difficult and that way you know when its going to be fixed plus if a stud snaps then it can be sorted by the machine shop at the same time.

Presumably, 90 degrees past tdc is 'safe' from piston/valve view, how does tunnie know where TDC is on a 2.2?

Hasnt Tunnie lent his Dad either the Senny or his Omega? That way theres no big rush.....id have thought  :-/.....or perhaps he has lent his Dad the rust bucket.....hence why his Dad is in a big rush to get his Omega back  

[TheBoy]

He won't drive the Senny (understandable), and won't drive manuals (sensible man).
