Okay you cleared up a lot. Technically it may be your injection pump. Since all your hard lines dribble. Plus you have cleaned out any crud that may have been present or not in the delivery valve.

I suspect the number one injection pump element may be damaged. To the extent it will still pump but is no longer able to reach the injectors pop off pressure required. The piston fit to bore inside the element is leaking more than is permissible.

If injection pumps are easily and cheaply available in your area I might locate one. If not cheap or readily available I would take a spare hard line. Cut it into two pieces and plumb a pressure gauge in. Then hang an injector off the end.

Then I would see what pressure is obtained when hand rotating the engine over in comparison to another element. One that you know is still hitting a release pressure.

Sorry but WVO type fueled engines are more prone to injection pump issues if that is the fuel you have been using. You also might have other elements in that injection pump that have more wear than desirable. Perhaps even being close to compounding the issue.

I did weight the possibility of accumulated fats in the base of the injection pump causing an obstruction. But feel since you see a dribble at each injector nut this is not the issue. I can of course be wrong.

It is important to mention what fuel was used early in a thread if not diesel number 1 or 2.. Not because people will pick on it as once was the case. Just changes the more likely possibilities. I am not sure either but with no mechanical lift pump this means no check valves that with an electric pump normally would be no issue. Yet still might account for your fuel back draining from the element you noticed. I was wondering about that earlier.

So thanks a lot that was really helpful. My injectors were firing streams of fuel when I tested them except the number one and I eventually got it to pop as well.

Here's what I found when I removed the valve cover. The lobes on cam are excellent barely any scratches on only one of em. Also they weren't worn like I remembered. But all the valves were over tight and my chain had half inch of play. Upon further inspection of the chain I noticed the tensioner was stationary and it should push out against it no matter what because of the spring inside it. Took that out cleaned it up and it works great now holding the chain under tension all the time. With almost no slack. I checked the timing by line up the cam mark with the tower mark and it's only maybe 3 degrees off! After adjusting the valves and strapping the valve cover back down. It takes maybe an hour but the battery is low and needs charged. It starts but is idling hard and dies at stops in drive.I adjusted the rack damper pin in all the way but barely a difference. Also tried adjusting the delivery valve seats. They wiggle left and right to line up the hole on the side with the groove of the shaft piston.

In the attempt to start it I pulled the air tube off the turbo and it dumped out about half a quart of oil and the turbo impeller opening continues to dump oil when I try to start the car. I ordered a full rebuild kit for it with the new 360 degree thrust bearing. Also it's very apparent your thrust is going when you drive it now. Doesn't punch ya back in the seat quite the same and of course it's directly related to low power at take offs. Could the pretty blown turbo be giving me an idle problem?

Also I compensate for the lift pump check valve I use.a in line filter with a one way valve built in and cleanable....spendy little sob but worth every penny lol

Well the turbo needs rebuilt anyways. So it will be a wait and see. I feel the engine should still idle well but there is no certainty.

Under many situations I would run a cleaner through that injection pump. Actually a real soaking. It could unfortunately produce bad results if some of the injection pump elements are weak.

Weak elements could also upset cylinder injection timing as well as volume. Now if you can find a spare injection pump stlll on a car with fuel in it cheap enough I might entertain it.

After making sure air is not playing a role in any way currently with your injection pump. Once another injection pump is in your hands or in sight then I would try a real internal soaking of the current injection pump.

This will do one of three things. It will remain the same, Improve substantially, or make it worse. Right now it still runs.

Personally I do not like the engine quitting at idle. This is not a good symptom either. Remember these are just thoughts I have. Not certainties.

For example I have no solid idea of why the number one injection pump element came back up to pressure. If it's piston was stuck at the top of it's bore the hard line would not have dribbled like the others. I guess it could have been draggy in it's bore though. If there was sticky goo involved.

This is why I thought a good soaking may have been warranted. At the same time sticky goo in there may be the only reason you have a decent seal at all. There has been a lot of fat flushed out of the injection pumps on occasion when on WVO.

Got the idle problem pretty much licked. I picked up some new fuel lines and in the process of replacing them noticed the number one injector return line was half off and frayed. I snipped and replaced it with a new section. Also I had replaced the check valve with a heavier one six months ago So I went into my harbour freight spring kit replaced it with a softer one. Got the car started air out of the lines and it idled much better. Let it do that for fifteen mins or so put it into drive held the brake and it didn't die but did lurch a bit.

So I cracked each injector nut and the number two didn't give much idle drop. Tomorrow on break at work I'll pull this injector out and clean it up and see. If not then replace the spring in my IP check valve with a stronger one. If nothing still then I'll play with the position of the delivery valve seats.

Just so we're on the same page perhaps I wasn't clear but the hard line never dribbled it shot streams of fuel when I had it off the injector it would barely even dribble out of the injector. Also I've become very intimate with the inner working of these injection pumps and they are very hard to break.

Yes they are durable. This is why the injection pumps are sometimes the last thing to suspect. Sounds like you are slowly getting there. I totally agree being on the same page is very important as well as you mention.

I assumed you were just slightly loosening the nut at the injector and getting a dribble. Never considered a hard line totally off. Sorry.

I might try running the engine on straight diesel to see how it does. Maybe you have. The diesels thinner viscosity can sometimes indicate something.

If it will run on it then pretty certain the injection pump will tolerate a real internal soaking cleanout. You could be processing fats in there into the delivery valves causing upsets.

People have reported gobs of stuff coming out their relief valve port after injection pump soakings. Kind of a crap shoot but at the same time has fixed issues many times. Otherwise you risk being in a vicious circle situation. At the same time it may not be this at all.

My thoughts go back to people that have purchased WVO burning cars in the past. If those cars had engine issues I used to recommend cleaning out the fuel system first. At least unlike many people in the past that did conversions. You know how things work and seem to know what you are doing.

Did you consider that you might not be changing your oil often enough? There is a chance that chain tensioner got gummed up with wvo component in the oil. What you described about it was unusual. Just something I would think about. It could be something else that caused it not to function.

I've been running on diesel for weeks now and I'm usually always mixing my oil 50/50 with diesel. Also I really try to meticulously strain and settle the WVO. I like the idea of a soak though I'll wait till summer when it's warm though. Thanks again for being so patient and helpful.

I am just glad to see you are getting it sorted out.
