Cylinder Head torquing
Having steam cleaned engine and bay and also replaced the timing seal and cover I find I have a weeping cylinder head at the front end over cylinder 1 (radiator end).
Do I simply torque down the relevant bolts or am I looking at a more complicated procedure or even replace the gasket?

Re: Cylinder Head torquing
Is it head to block? If so, new gasket required.
If however, it is rocker cover to head, just clean and seal with a thin smear of liquid gasket assuming the cork seal hasn't been squashed flat by over tightening.

It's head to block. Rocker cover seems fine.
Never removed a cylinder head. No where did I put that manual?

Re: Cylinder Head torquing
Thinking about this further, I'd just re-torque the head and keep my eye on it. The oil way is outside of the cylinder bores so it could go on for quite a while before you got any adverse effects to performance.

Pull it down evenly to 44 ft lbf and cross your fingers. Was the head disturbed recently ?
Re: Cylinder Head torquing
Thanks guys. Cylinder head not been off in my ownership of 30 months.
I assume I re-torque all head bolts starting in the middle and working out spirally?

Re: Cylinder Head torquing
Yes, that is correct.

Re: Cylinder Head torquing
This is the correct sequence of undoing and doing up/setting the torque of the 9 stud cylinder head nuts.[frame][/frame]
Some other workshop manuals start the tightening sequence at No: 2 above but the schematic is as recommended in the Minor Wksp manual section AA Fig: AA5.

Re: Cylinder Head torquing
Thanks guys esp Philthehill for the drawing. My working spirally would have been a bit different! Will report back in a few weeks to see what the results are.
Cheers for now.

If you haven't got a Workshop Manual - download it free - just search for 'Morris Minor Workshop Manual'....it's there and free.
Re: Cylinder Head torquing
Hi Bmcecosse - got the workshop manual which I was given a week or two after my birthday when I bought the car. Trouble is can't find it! Not looked too hard and last had it in UK over summer so could be in the garage somewhere I suppose instead of the bookcase where it's meant to be.
Might just download a copy though. Thanks for the tip.
