300tdi Head gasket ??

<< < (3/6) > >>

minty:
me and funky rhino have just done his and we got the wrong one to start with. don't worry you will no straight away if its the wrong one as with the above you need to take into account how many times the head has been skimmed as well easyest way take the one you take off to mach up and get one a bit thicker job done. you will need to have head skimmed and you will need a thin 19mm socket or so attachment to get to the head bolt at the back of head near the bulk head. the just follow the Haynes manual you wont go wrong.

cheers matey, dont think ill be getting it skimmed as afaik it is not warped in anyway.  So hopefully strip off replace gasket and back on  :dance:  Just want it done quick  :roll:

Range Rover Blues:
Check it's flat with a steel rule and feelers, if it's warped you are wasting your time putting it back on.

Minty, why fit a thicker gasket if ther head has been skimmed? the head it utterly flat, the thickness of the gasket is purley to take account of the varience of piston projection (above the top of the block at TDC).

Muddy:
Did this on a defender about a month ago, head pressure tested (300's often crack) skimmed and all new bolts and gaskets came to about £165, quite expensive but at least i knew if i put it back together correctly it should be all ok (which it was till i wrote it of 2 weeks later :roll:).

Don't forget that there is a certain order to torque the bolts up in and the last 30degree takes some doing. :lol:


RRB, out of interest did you pop a core plug to drain the water when you did it? and if so which one did you do?


Cheers, Will.

marky:
On mine there is a drain plug about half way down the block on the turbo side near the front.
