Hi everyone!
I've got an interesting one for you today! on my '91 E250 Club Wagon 7.3
So late last year I had a miss fire and shake at idle, witch I determined it wasn't injector related, upon removing valve covers and pressing down on the rocker arms push rod side, I found I had 3 bad lifters that weren't holding pressure.
So I replaced all lifters, put everything back together, still had a slight miss, found a bad - 1 month old injector on #6. replaced it with another brand new one. Engine ran like brand new for 10 min idling.
I shut it down to finish putting everything back together, start it back up, miss fire is back and dry lifter tick.
After cursing every word I know, I said the hell with it, drove it like that for a lil over a month before storing it for winter.
Now I have everything opened up again (intake not off yet), I have both valve covers off and all my lifters have pressure in them? Engine been sitting for 3+ weeks now.
And it's got dry lifter noise when it runs, worst at idle. When a lifter gets noisy isn't it because it's not pumping up or holding pressure?
What else can this be? Any other way of finding out witch one went bad when all of them are holding pressure? It is miss firing, you hear it through the exhaust and has a very noticeable miss if you put your hand in front of the tail pipe.
Long shot but could my new IP be causing the miss and putting extra pressure on a lifter making it noisy?
I'm totally stomped here, and believe me, its no walk in the park getting this deep into an IDI that's in a fully loaded van...
