Long story short-- 2005 F150 5.4 crankshaft never had the #5 rod journal oil passage drilled into the main oil gallery. Any machinists out there who can verify if the passage can be drilled and if it would be cheaper than a remanufactured crank? Thanks. BTW. Engine is still in truck, picture taken with camera sitting on front axle.

 

It ran like that and didn't damage the crank or bearing? How many miles?

 

230,000 km. Yes you read that right.. The bearings were hammered on journal #5 but all the other bearings look new.

 

I gotta' 3/8 drill that'll fix that. Then just clean up the burrs and go. lol

 

If you don't drill it, it has to come out.

If you drill it and miss the passage, it has to come out.

If you don't drill it and pull it for a shop to drill, it has to come out.

If you drill it and hit the passage, it stays.


I don't see any downside to drilling it insitu.

 

One of 2 things will happen.


Either drilling it works, or it doesn't work.


You got a 50-50 chance.

 

Couldn't you pull the corresponding rod cap off the next journal and get a pretty good idea of the 'angle' you should be drilling?




Also, I was thinking - I MIGHT use a slightly smaller drill bit so drill burrs would not be a problem just inside that depression. ?? Interesting problem.
