DOH....the story continues

So after my last post, i had re fitted the water outlet from the head and waited in hope that no more water appeared and started running down the block, well 48 hours after doing this the dreaded drips continued to show up.............................

BUGGER!

this now means the problem lay with in the head itself, so the tool set was cracked out and off comes the head again.

After removing the head and stripping it of the intake manifold it was time to see where the problem lay..... now before the head was refitted when i rebuild the engine i has taken the head to work and had checked it for flatness, i didnt rush in to skim it as i have read in a few places that the limits you can actually take off are very small with mazda head, so with the aid of a surface table, some parallels and some feeler gauges and a height gauge me and a college checked the head for flatness, now at the time everything seemed to be fine, and the head had seemed as flat as it could be, so it was decided it would be fine to re-fit.

after removing it for a second time i checked it again, and again every thing seemed fine........ so i cracked out the inspection lamp and found a straight edge, this then reveled what i should hope to be the cause of the problem, one corner of the head has actually lifted and is not sitting right by what appears to be .25mm, knowing my luck its probably the one corner we didn't check the first time round with any of the fore mentioned equipment, its also the corner to which the source of the water seemed to be originating from.

so the head will be making its way back to work tomorrow to be skimmed, which stupidly i should have just done in the first place, lets just hope it cures the problem this time.

But in the mean time during all of this i have managed to complete a few other little jobs from the list....

the roll hoop is now fitted and bolted up for the moment, altho this will need to be removed next week so that i can set about making up my boot box cover.

with the head removed i have also been able to gain access to the oil pressure switch, which i was not able to do up due to restrictions on getting a spanner in to tighten it up. so that saves me another job, all tho it could be said that removing the head was a rather radical approach to tightening it up ;o)

Front headlight raiser brackets have been fully finished, painted and will be fitted over the coming weekend, also meaning i can re wire the head lights back in.

i have also with the head removed been able to fit the cable tie anchors that i should have fitted down the drivers side of the engine bay to hold the wiring out of the way, and which i could not fit because the inlet manifold was in the way, i have also moved the wiring to the alternator and starter.

have also started to make my IVA dash, the ally panel has been bent with a good sized radius on the bottom of it all tho i will also be covering this dash in foam and vinyl to be completely on the safe side. and i will start to trim this in over the weekend.

i will add a few more pictures over the weekend for the parts that i have recently covered.
