Timing Help?

Timing Help also Blowby

Since I've had the truck, white smoke has always come out of the exhaust.

I know it's unburned diesel by the smell.

The truck most likely has 166xxx on it (odo rolled over).

I know it could be the injectors or a retarted timing, or some other possible things.

Anyway, I was wondering if I should see if I could get rid of the white smoke by advancing the timing a little bit.

If so, how much do I advance it?

Some advice would be nice.

Thanks!

I've also taken two videos.

In the first you can see the white smoke from the exhaust

In the second video, I came across some smoke from the oil cap and dipstick (I think this is called blowby but I don't know what this means)

Any help would be greatly appreciated.

Thanks.

Can you tell us how many miles are on the injection pump and injectors? If you want to advance the timing please make a mark with a center punch in the joint line where the pump meets the housing its bolted to. That way you can return the pump if it runs worse after moving it and you actually see how much the pump was moved. To advance the timing the pump must be moved towards the passenger side fender. Move it about 1/16 inch for starters.

It appears to me that the pump and injectors are the originals.

The ODO reads 66,380 which I would say is 166,380, as this was the PO's farm truck.

Should I be worried about that blowby?

Also, would I follow this guide?

Where would I make a punch?

Will do. What about the blowby? Could you inform me on something there?

I "think" not sure where I saw it! May have been one of the guru's here, blowby at idle looks like a coffey pot perking.
Now many younguns never seen one in action,,,,, a light haze easily dispersed with a decent " blow out the candel(1)"
Not an 80 yr old firestorm.

Right. I know for sure I saw it, it dissipated when I upped the RPM's. I read somewhere about cleaning/changing the CDR valve.

Yep
I did the cdr test /cleaning mel put in the stickies ,,,on the 88 with the banks conversion ( lousey *** design) did little for blow by...helped with intake oiling. The second vid looks ok....

Interesting. I appreciate the help.
