SBD cam cover breather modification
http://www.sbdev.co....odification.htm





Removal of the small cam cover breather hose connection using a hinge pin removal tool, the hole will be blanked off with a nut and bolt.






Cam covers now off to be put through a commercial parts washer prior to being paint stripped ready for high temperature coating by HPC

will be interesting to see how this looks on the roof of the Manta

[opelmantagsi]

finally got round to tapping out the cam cover to blank off the breather pipe connection not needed when running carbs.
Rather than use a nut and bolt  I drilled out to 6.5mm then tapped out M8x1.25 used stainless steel dome head alan key bolts with thread lock
these can now go to be blasted and HCP coated, the coating will go over the bolt head.







my engine is still with the engine builder, should get it back next week now that this has arrived from the UK
one serious head gasket, I can see now why the cost so much.

Heck!!!   that is good looking engine build.

[opelmantagsi]

I only wish the missus was so enthusiastic

[opel2000]

He He, times I've been told off for leaving cylinder heads on the kitchen table. Never really understood why they saw the items as unattractive, must be a girl thing
All looking very very good Derek

[Kevin Abbott]

Wow, looking great. Quality work and loads of time spent.

Yeah, those Accralite pistons are thing of beauty, would have preferred to have mine on display in the house rather than hidden away in the engine.
BTW I think those are flat top pistons, race top are domed with a dish in the middle - http://img.photobuck...ct/SP_A0228.jpg

I would not go with powder coating again. ( You quoted)

Why  is that then? I have never used it, but was always been very  impressed with the finish I have seen with it.
This is a brilliant project, just can't wait to see the finished car, but like you, wait I will have to!!

I found it can chip off, had a couple of bits chip off on me and made me very grumpy indeed
got a set of wheels for my boys chevette powder coated black that I will be taking back as its all flaking off....could have just been applied wrong?
anyway I am getting these guys to do my rocker cover and belt cover, will put up pics when I get them back this week

the 120amp alternator I am using has a 10mm bolt hole, the standard alternator bushes are holed 8mm
easier to get some split bolt through bushes run up than try and find replacements (possibly Powerflex for Saab 900?)
anyway here is the plan, these are designed so there wont be a washed on the inner side of the bush between the alternator and the bush.
also sorted out a rose jointed adjustment bracket for the top mount, will post pics of that later

[dynamytedan]

looking good !  very good .  those brake servos in the boot with an electric pump is a cracking idea .
much better than the spear pointing at your chest in the behind the headlight servo mod.

Excellent rebuild thread fella... Have just read from the begining and love the attention to detail and innovative ideas, along with your determination to source the parts you want from around the globe!

You must be a patient man, as I know only too well just how long the research on the net takes, let alone the fabrication, prep work and parts fiting.

I'm quite envious and inspired by your talent, so will watch the progress with interest!

Out of a Honda Integra I picked these up for around 200 quid your money then spent the day getting them clean, they have come up well, might need to replace the bolster foam at some stage tho.
amazing what a pressure washer, persil granules and a commercial wet vac can do
I am hoping they fit in the Manta, the shoulders look a bit wide but got to be worth buying as I am sure I could sell them now cleaned up and make a profit.
need to source the red materials for the rear seat if they do fit
