The water continued to show....

In my previous post i had just reassembled the engine after having the head skimmed, to see if this cured the water leak... well unfortunately i have to say the water has still continued to seep around the sides of the head...... BUGGER!!

Now we are onto the serious business of looking for a warp in the block, so it was back off with the head again, ( i am starting to get very quick at doing this now ) after removing the the head i brought home a long parallel from work and set about checking the top of the block for distortion.
it then became clear that i also had issues with top of the block being warped, at the moment it looks like there is a .04mm deviation in the center and across to 2 corners, now reading online it appears the maximum tolerance for flatness on the mazda block is .015mm. so now it was time to take the engine back out and strip down, ready for a trip to work to be machined.

So yesterday the engine was taken into work, first job was to remove the 2 locating dowels in the block that position the head, i then made 2 new ones to replace them. the block was ten set up on the machine and clocked up, it then showed as expected slight distortion of about 0.038mm.

so a light fly cut was set up and the distortion was machined out, i am now really hoping that this has cured the problem, other wise i might be looking at a new engine if this doesn't work.

i shall find out this week!
