Are the timing gear marks in a slant engine marked with "dots" like in the V engines?

If so, do the dots go to the inside facing each other to line every thing up?

For those that read my other post on my 170 being VERY hard to turn over by hand...........Well I think I may have roached out the timing gear as well as wiping the distributor gear.

Ugh! I should know by the end of luch time today though.


Thanks,

Chris E.

Think I answered my own question. Just pulled the timing cover and there is a "dot" on the cam gear and a "o" on the crank gear. Also noticed 2 lines on the cam gear??

They DID actually line toward eachother up when I rotated the engine by hand. Although the chain was hanging with more slack than I thought could be possible!

The engine just doesn't sound right when I crank it and I was really thinking I skipped the timing chain somehow. Is there any way these timing marks could actually line up and the engine still be out of time?

Thanks for bearing with my ameture questions here

The dots should face each other. Another way of describing is that the dots should fall on a line between the centerlines of the cam and crankshaft.

I mention the second description because I once heard someone mistakenly line the the dots straight up and down because thats how they learned on a V-8.
No, but be sure to replace that old timing chain before putting it back together. I usually leave the gear on the crank and just replace the cam gear and chain or even just the chain if the gear is in good shape.

Remember, you may still have a hung valve or lifter if moisture is involved. Take off the valve cover and check for bent push rods and while you are under there, tap the rocker arm on top of each valve. The closed valves should give a nice 'thunk' as they snap back shut and the half open valves will have a similar feel of springyness as they snap back to the rocker/ rod/lifter. Don't need a big hammer, you are going for the feeling, not lots of movement.

Slant6Ram, Thank you much for the good advice. I pulled the cam gear and chain at lunch today. I can't tell if the gears are worn out but I ordered both gears and the chain anyhow.

I will pull the valve cover today after work and check the rockers like as you have suggested and look at the push rods.

Again, thank you!

Chris E.

Problems, problems...danger, Will Robinson, danger!

There have been timing sets for the slant-6 that were in more-or-less correct alignment only when the dots lined up with cam and crank...with both dots at the same clock position as viewed from the front, rather than with both dots closest to each other.

There have also been timing sets on which lining up the dots (either way) doesn't get you within sight of correct cam timing.

So yeah, lining up the dots so they're closest is probably the most common indication that you're in the same neighbourhood as the ballpark of correct cam timing, but it is not the only one, and it's devillishly difficult to figure out what you're dealing with unless you do some super sleuthing.

As John Jerome wrote in Truck, his highly entertaining account of rebuilding a '50 Dodge truck, "You can't get the cam timing right until the cam timing's right!".

Well that was a great confidence builder So, I'll be taking a chance either way I do it!!!

Well, first I'll make sure that the marks on the new gears are the same in relation to the campin and the woodruff key, as the old gears.

The old gears were in with the marks set closest to eachother, the chances of the marks lining up after having a chain slip are slim to none. So I'm gunna work on the premise that the cam and crank are where they should be respective of eachother.

Then cross my fingers

The cam tining will be correct, whether the dots are towards each other or with the crank dot at the top and the cam dot at the top. With the cam and crank dots towards each other, you are timing the cam at #6 TDC compression(which is correct). The other way you are timing #1 at TDC compression, and you will have to retime the distributer 180 degrees.
