Cam timing is complete, I think. HELP
 

This may go down as the dumbest question ever asked but I completed the cam timing per Wayne's book and the Bentley manual tonight and everthing seemed to work out fine.

My question is I took pictures before the engine was torn down and comparing the left/right sid cam sprockets the pins were only spaced about 3 holes apart from each other. Here's the pictures

I've been working long hours and am probably loosing it but now the pins are about 180 degrees apart (sorry no pictures). Shouldn't the pins be pretty close in spacing to where I took them apart after it's timed again?

My cam timing procedure
Set valve clearance #1 intake
Turn to TDC
set up dial indicator
turn until I get the correct lift on dial (1.25mm)
take out cam nut and pin
turn to line up notch with case split
reinsert pin and torque bolt
turn over twice and check lift
repeat for #4

Semmed pretty simple but the pictures got me thinking I messed up, I can't envision why the pins would have moved.

it sounds like you did it right.

since there are more holes in the gear than dwells you'd have to put the gear back in the exact same orientation within the chain to be able to put the pin in the same dwell.

Just to confirm #1 and #4 are supposed to be 360 degrees apart?

360 degrees of crankshaft rotation? Yes.

btw, I didn't see a mention of preloading the chain tensioner sprocket during your procedure. This will help maintain consistency when timing 1 and 4.

Brian the key here is #1 and #4 are 360 crankshaft degrees apart. You did that. Should be fine.
Nice pictures. The timing chains are near the end of their life. Nothing critical, but I would plan on replacement within the next year or so.

Thanks guys,

The chains in the pictures are the old ones before I started tearing them apart, I replaced them with new ones during the rebuild and the tensioners are no where near that extended.

And yes I was talking about 360 degrees on the crank and the chains were loaded when I did the timing.

I starting to get pumped up, another week or so and I hope to hear the sweet sound of success.

Thanks guys

Brian

Good Luck Brian,
