F7r Head Removal

[chip]

Doing the headgasket in the bay isn't too bad, i've done it once before and I'd probably do it that way again unless the engine is already out

Depends on the reason you are doing it and when you last inspected the shells and changed the pumps etc really.

Most of these cars that are doing the head gasket now are doing so cause they are so old and lots of other parts are on their way too, so its a good excuse for a freshen up of the rest at the same time IMHO

Mind you im probably more fussy than most like that, mine hadnt blown, was still working fine, didnt make any rattles or knocks and I pulled it apart and freshened it up just as a matter of course because I have been giving it death round track for a couple of years so felt it was due about now.

Ill be whacking the head back on tomorrow night when i get back to Leicester so hopefully i can get the engine rebuilt this weekend.

just out of interest does anyone have the torge settings for the CAM pulleys and tensioners?

Haynes manual has all the torque settings you'll need.

All well and good if you have one!

It's 37 lb/ft for the camshaft sprockets and tensioner nut.

Cheers for that wobba,
If i weren't so broke and hand more time on my hands id get a haynes manual!

Is it 50NM for the crank pulley and other bottom pulley as well?

got my engine in yesterday and cranked it up along with all the electrical problems of no ignition or fuel pump, theres water pissing into 3 piss-pots,

had the head skimmed & pressure tested
new gasket & bolts
cleaned bottom end with rag and diesel
gasket on right way & locating dowels in the right place
torqued to 30nm in correct sequence
then to 50 degrees in correct sequence
waited 3 mins and loosened completely in reverse order
then same again to 25nm and 108 degrees and left it.

somethings obviously not right and for water to be in 3 cylinders it suggests the head or gasket or both aren't sitting correctly.

i missed donington today in the clio but luckily my mate brought his lotus 7 to save the day with a sympathy drive.

oh well engine back out.................

You've not done something stupid like attach a water pipe to a breather pipe or something have you?

Seems unlikely to be that 3 cylinders would all fail on the water side of things on a new head gasket even if you arent really sure what you are doing, its hard to get it *that* wrong bolting down a head.

[scratabout1988]

i don't think so pretty sure i wouldn't have, but seems a logical explanation if so as that head was definitely sitting right and torqued down to those specs,

In sheffield during the week but will be back in Leicester friday night so i will double check when i get back,

for now i flushed all the water out and chucked some oil into the bores and cranked it to stop the rings rusting.

I'm cycling from John O Groats to Lands end at the weekend so won't be able to do much on the car for a couple of weeks anyway

[scratabout1988]

oh and i seem to have alot of compression as the water chucks out like a fountain,
