Its running now

Can't reach the 6th glowplug but 2 of the 5 we could get to were bad. It took a LONG time to get it started after we replaced the 2 bad ones.

We're reading 150psi on 2 cylinders (including the #4cyl) and 300 on 3 others. Not so good. I'm not sure if it'll start again in the morning.

So, how much / how hard would it be to have the valve lash adjusted?

You can do the last glow plug by leaving it attached to the bus bar. Just loosen the nut a little so the plug can spin, then use a wrench to screw it out. Use the bus bar to install the new injector. It works pretty well to fish it in there. Glad to hear its running. Those two numbers are pretty low though. Definently do the valves.

That's a common story. The front 3 plugs are easy to access so they get replaced often. #4 is not as easy, 5 is very tricky and 6 seems almost impossible to most mechanics. Therefore the rear ones essentially never get replaced. The car starts OK most of the summer and fall, but then winter comes and the cold temps finally hit and all of a sudden the engine is dead.

Glad to hear it's running again. Replacing the #6 plug is not that bad if you are patient. I have an 8mm wrench with an S-bend in it that helps to get the nut on the terminal loose, and then you just have to take your time and screw the plug out, going in through the rear belt. If you're really having a hard time, removing the #6 injector makes access much easier so that is a way out if you need it. I'm not surprised it was tough to start with the new plugs in, since the rings were probably pretty gummed up with excess fuel from previous attempts to start by that point. It won't be as difficult next time if it now has 5 good plugs in it, though if #6 plug is dead (very likely it is) it will have a miss at startup.

Congrats on getting it going.

Oh, and V8Volvo, my car has surprisingly few miles on it. I just rolled over 120k on it

Looked like 3 of the 6 glow plugs had been replaced before and the two dead ones were the older looking ones.

I'm hoping we can do a valve lash adjustment sometime soon but we're pretty busy now so it may have to wait until the new year.

I would really try to get that last glow plug replaced before winter really sets in. I would also change your oil after you had all that starting stress. You may have gotten a decent amount of fuel down into the crank case.

My dad was a mechanic in the 80`s and have fixed alot on these engines and he says that if one plugg is broken will they other get broken to because they burn up because of the extra power from the broken plugg. It is like a fuse. My dad also change the glow plug behind the pump for me when i need it

You should check the fuel pipe and the hole fuel system of your car.

Told ya.

120k? It's just a baby still. If you keep good synthetic oil in it, don't overheat it, and keep up with your timing belt changes it will never die.
