Diesel Knock

Posted by Royse on December 13, 2013 at 16:40:49 from (69.36.49.186):

You may have seen my previous posts about this little diesel.

I had the head off and replaced the head gasket.

Head was cleaned, pressure tested and checked for

warps/cracks by the machine shop.

Timing gears were off to replace freeze plugs behind them.

I got it put back together, set the timing as the book said,

which is adjusting the pump gear until fluid just starts pumping

out of the #1 line at 16* BTDC.

It wouldn't start. Just an occasional fire even with glow plugs.

It is in my shop where it is 60 degrees, so not cold.

I adjusted the timing a bit and now, with about 15 seconds of

running the glow plugs and 6 to 10 revolutions of the engine it

cranks right up.

Problem is it hammers badly.

It had a "diesel knock" at idle before I tore it down, but nothing

like this. It is and extremely loud, deep sounding knock. Not like

a valve train rattle, but I can't tell where its coming from.

There is 65-70 psi of oil pressure registering on the gauge and

I made sure I had pressure before I ever tried to start it.

I didn't use any ether.

What do you think? Timing too far off? Injector plugged?

I have a hard time believing its a rod, since it didn't do this

before and nothing in the lower end was disassembled.
