Ok so i drilled out the blocked off holes and it worked fine. Bout 10mm down then it joined up with the rest of the water passages, gave it a thourough blasting with the karcher to get metal shards out. I've whacked the head back on but typical tassie weather, it starts to piss down with rain and my garage isnt free so the cars outside

So ill hopefully get it done tomrow or later tonite.

Yes blofly it sucks rectum, big big rectum. Ive been doing everything right and this is how my 'faithful' datsun repays me

Ok well an update, i had an ephiphany today.. They dont happen often so bear with me!

Ok so i have an H89 head that has water galleries to the inlet manifold but i have had these since blocked off due to the twin 40's im running has no galleries in the manifold so i got these blocked up. But then i realised that this problem has only happened since this has been done so then i was thinking what could have caused this to happen, and this is the evidence i found!

There are galleries on the deck of the block as we all know but i seem to have found that there has been 2 galleries blocked on the BOTTOM of my head (maybe the shop compensated for the blocked galleries and plugged these up).

Pictures mean a thousand words













Well thats the evidence i have got and cannot think of anything else in order to make this happen (apart from leak in block )
But as i said before, the problems only happend after ive upgraded my engine - different cam, bearings, twin 40's, head plugged and double valve springs. So really this 'upgrade' can only have lead to this problem!

Any comments and thoughts welcome guys

Cheers
Dave (kinda more happy as i hope this is the problem )

yea i did the exact same thing as unfamilia... worked a treat and didnt notice any differences or breakdowns etc.

Theres alot of useless emmissions and vaccum lines on our beloved dattos! Maybe not useless but not needed (only to pass rego/factory specs).

Dave

Anyone at all ?

yeah they are quite close to the idler arm, i was quite skeptical when fitting mine but i have different mounts for my engine so the engine sits a bout 2 - 3mm to the left more which is good.
Get the grinder out or yeah replace the idler with a later model sunny/120y ones.

Dave

Ok an update, got the head pressure tested and checked today. No leaks at all, wasnt warrped and performned fine.... damn

So its back to the drawing board, i had a talk to the bloke and at worst its a hole in the block/water passages but this is the worst of worst scenarios but the most identifiable as there are really no other places where water can mix with oil. Unless my water pump/timing cover are mixing??

Any thoughts guys? I think its time to give up on Datsuns for a while then come back to them when i have a reliable one that loves me back

Cheers
Dave

Whens the next one guys? Are we still following along the same lines of first sunday of every month?

The ute will be there (if nothing else goes wrong) and it will be my first appearance for a while so will be good to catch up with everyone.

Any more interest?

Cheers
Dave
