Title: NO OIL PRESSURE... BBF
Post by: enginedoctor on October 07, 2009, 08:49:45 PM
Fresh rebuild 460 Ford...
Guy brings it in... Local shop that built it , blew him off..said improper break in  :screwy:

Upon my t/d & inspection... I find the crank to be .030/.030  with std. rod & main bearings installed :banghead:

So much for blueprinted assemblies....Oil clearances were over  .015 thous. across the board  :thumbdown:

Yaaa blame the poor customer  :thumbdown: :thumbdown: :thumbdown:

Just throw some 290 wt oil in it and let it roll......, maybe a bucket or two of axle grease..   :thumbup:


I did one in about 1999 that was missing the center cam bearing....Not spun...MISSISNG. LOL..

Did the builder make it right after finding out it was his mistake?

If not, I think it would be a good time to "drop off" the crank to the builder.  Maybe "accidently" drop it on his foot  :mad:   ;)

Not really, I had $3000 in my rebuild and I reused the cam and did the build myself.

Just FYI   the rule of thumb is about  $ 1200.00 per  100 hp. Plus Parts ;D

$1200 sounds conservative  ::)  but then I do tend to get carried away  >:D

I remember back in 1975', prior to getting into the biz:

I sent out a BBC to a shop and paid them $2200.. just for basic machine work, No parts, No assy!
Back in 75"  ;D

0.015+ on the bearings, eh? Easy. Blend Valvoline 60-wt with 1 can STP oil treatment, spike with Lucas Oil Stabilizer, pour into crankcase. Add a lLttlefiled 12/71 on top with a mechanical injection system, use methanol for fuel.
