Cam Chain Sprockets Alignment?

[sfcpiet]

Many thanks to all contributing.  The straightedge method of aligning the sprockets makes sense. 

I put the No. 1 piston at TDC before putting the head back on, so with the marks on the sprockets aligned with the tops of the center bearing caps, no valve to piston introductions should occur.  I will check with the pointer on the crank after putting the primary back together, as well, since the No. 1 piston could be on it's compression/power stroke at TDC, not exhaust/intake.

If it's up, it's up.  The cams define power or overlap stroke...

Either 3.2l V6 or 4.2l V8, can't really tell from the end, just about identical.

And wtf are B8 plugs fitted to a 1000SFC? :

Using to plug holes.  What plugs are recommended, btw?  Getting close to trying to fire up.

NGK B9ES (or EV if you can get them, Gold Palladium tips)
The 9 is the heat range for high comp triples, and the 8 range (for NGK) is the range for lower comp engines.

I pity the poor bastards that wrench on Audis 5 days a week.

I hope my 1.8L doesn't look like that inside.

Looks like my Touareg FSI v-8, chains on the back of the engine, 55hrs labour to change a chain tensioner, ask me how I know!

According to the picture links the top one is a Dodge Challenger and the bottom one an Audi 4.2l V8.

Wasn't aware Dodge fitted Audi engines...

Top pic shows the lower engine with heads removed.

Yeah I'm guessing the audi pic was on the dodge forum as a "So you think the dodge is complicated" type of thing....
