Christian, don't be impressed just yet. If there is still a problem with the compression, I could have made things worse!

Teresa,
are you still getting white smoke with no knock? What is the temperature where you are? Unless you're loosing "coolant" or making bubbles in your coolant you may just be seeing steam from temperature.

Just wondering--Would that steam be present even if it was say 70* out?

I've seen it from an atomic four I used to have even when it was 90* out.......I'm wondering if cold water could cause it too as I've seen it while "motoring" at the dock.

If your engine starts easily when cold...your compression is just fine. Without adequate compression a diesel can not run. a 700 hour Yanmar doesn't need be concerned with compression.

I think the injector was you problem. Now... with 730 hours on your engine, the question is why is your injector clogged? Do you have a water separator? Small amounts of water in the fuel will damage injectors.

A white or light grey smoke can be signs of timing issues in diesels. A sticky injector could have been it and also caused the knocking noise. More often than sticking, injectors become weak and the problem is leaking or delivering too much fuel and therefore a black smoke. Are the smoke and knocking gone? You can ussually smell coolant in the "smoke" if it is there. I hope it isn't.

I'm just wondering, A do-it-your-selfer may miss this.
Have the head bolts been re-torqued? This should be done early on when an engine is young. Along with valve clearances.

Have fun!

Hello,
Can you give us a brief but specific re-cap of what happened? Why did it not start and then it did—what did you do?

You have replaced one injector and now have changed the symptoms in what ways exactly? What are the symptoms now?

Coolant level?
Oil dilution?
Visible exhaust and if so what does it smell like? (Fuel or coolant?)
Does the visible exhaust go away on warm-up?
Is the engine warming up?
The knock is gone at all times or goes away on warm—up?
Has the injector replacement restored full original power?
Why do you think the spare injector you installed is an issue? Improper storage is not good but quite possibly had no negative effect.

I’m old and slow so help us out here. Look like too many cooks...........

To check the cooling system. There's a kit that has a fitting that goes in place of the radiator (header tank) cap. It has a means of pressurising the cooling system and a guage. The leakdown test simply is seeing if the pressure is maintaned over time. Advance auto has a tool loaner program if there's one in your area. I saw a diesel compression test kit last time at harbor freight. $60 or so. Simple testing tools tell the whole story. Also simple visual checks of fluids. White in oil indicates water, black or oil in water indicates crack or leak somewhere
