16v on b230 bottom end

[MrBill]

Okay I've had all this stuff for years and I'm finally getting around to doing something with them.

Question #1. Will the lower timing cover off an 8v fit? I'm trying to figure out the easiest way to check ignition timing and the such. I've seen pictures with it fitted, but don't really know if someone had to modify or space it out.

Question #2. Since I don't have the rear portion of the timing cover for the head, I assume the marks on the valve cover are for my cam gears? Just draw an imaginary line?

Question #3. What is the tensioning procedure for the yoshifab tensioner? I see how it spins and moves to tension, but how do I decide what is 'tight enough' for the setup?

Lower cover will need to be chopped in half. NO it doesnt fit to the head...

Tension!? Not so tight you can "play the harp", but just tight enough. There are tools to check if you really aren't sure.

Valve cover, yes

 

[ZVOLV]

Those marks on the valve cover, yes, they are TDC for the cams.

Cool kids on tbricks dont run timing covers!

Standard tension chec on some DOHC 16V Frod thing that the name escapes me now is "half a twist"..IE on the long run of the belt can you turn it 90* without a big strain? Good.

 

[MrBill]

So.. G?ttentite?

Volvo specs the timing belt tension based on engine temp and belt age. The specs are given in a number that corresponds to the value displayed on the gauge of special tool #9988500.

A ways down the page you'll find some different belt tension checking methods, one of them being the 90 degree turn method john mentioned.

so is this just for ignition timing or valve timing as well. if you are checking valve timing , pull the valve cover and use the degree kit i lent you. if you need a hand with setting up the kit, i will be back up in DC later this week.

looks like you're off half a tooth. I like to set things up so that when I roll the slack to the tensioner side, everything "pulls" to tdc.

 

[MrBill]

Yeah not timed final by any means. Gotta cut a groove in a crank pulley for that fancy crank gear and figure out that lower timing cover.
And a bunch of other stuff. J-pipe hits my oil cooler lines.

I like the penta aq171 lower timing cover.

[MrBill]

That is too expensive.
The belt routing hasn't changed enough to impact the fitment of the 8v timing cover. I'll get some standoffs and space it out some.

'That looks pretty sweet so far.^
