I think you can see the pics only if you log in to tapatalk. It forces people to use their software.
I cannot see the pics either.

Oof!

I need a new hosting service... and not photobucket cos its soooooooo sloooooowwww.

i suspect that the reason those pics are not displaying is the size, try a smaller size...... those are too big for the forum i think ......

Whats the max pic size for the forum to happily display? I will alter my phone camera settings to suit.

Well after many delays and being used as a reference, its going back together at long last! Cam is timed and fixed (my own gear adaptors) so just a few tweaks needed to the sump baffle and it can be closed up [SMILING FACE WITH SMILING EYES]
Should be ready nicely in time for when the syncro comes home...[img]//uploads.tapatalk-cdn.com/201705 ... 66e6ed.jpg[/img][img]//uploads.tapatalk-cdn.com/201705 ... e951a1.jpg[/img]

Fresh in this morning, two dozen 98mm pistons for 2.5 or 3.7 Oettinger engines with 82mm stroke.
The Oettinger spec 9.7:1 (49.5cc) are pre-sold and headed to Japan for 3.7 wbx-6, whereas the new 10:1 (45.5cc) will be available for 2.5 engines using AMC heads with the 23cc combustion chamber.
The 10:1 are a smidge heavier than the 9.7 at 515g but a good deal lighter than the OEM DJ piston which comes in at a hefty 585g (both weighed with pins , no rings) so that a lot less strain on your big-end bolts and bearings.

Hmmm ..you just cant beat a bit of piston porn!

For one reason or another, this engine has been sat around waiting for some love for ages...
It seemed like a good time to get it closed up.
I also got the heads stripped down and roughly degreased. The porting work is all Oettinger.

PS I get the blanking plugs BZP plated because on my 1985 syncro's original DG that same plug had perforated!

Camshaft notching for long-stroke engines. This allows the big end bolt heads to clear the cam, but the notches have to be "timed" relative to TDC to 4 pairs of different angles and not just every 90 degrees

Well this has taken an age! I've just lapped the valves in, they just need a quick tickle on the grinder and the heads can go on.
Funny thing is that after all this time, this engine now surplus to requirements.
If you want to join a very exclusive club and have your bus wear the Oettinger badge with pride, pm me.

By way of a reminder:

Engine #53, heads and inlet manifold fully ported, NOS 9.7:1 pistons and liners, my profile 2.5 cam (notched), new TRW valves, new con-rods (case clearanced), 26mm o-ringed pump, Speedshop stainless exhaust (s/h), DJ loom and ecu etc.
A thermostatic, fan-assisted oil cooler system with remote oil cooler is a highly- recommended option.
