Hello Fellows,

I am in need of the Ford crank case testing procedure. If you have the full testing procedure could somebody please provide me with it ( email,pm, etc). I'm looking to get more information about my engine than just flip the filler cap and see if it puff it off.

I would really appreciate it.

Thanks,

Brice

 

It involves the use of the rotunda gauge manifold rig.

The procedure is as follows:

Bring engine to normal operating temp.
Cork off crank case ventilator.
Remove oil filler cap.
Install oil filter cap adapter on the gauge manifold.
(If i remember correctly it was the middle one)
With test rig hooked up... run rpm up to 2500 for 2 minutes while someone watches the gauge.

It should barely move.

Having blowby in and of itself really only points at 1 or 2 things.
Piston/cylinder blowby...
Or an unseated valve.

If its bad enough that it is a concern...
Save yourself the headache messing with the finiky rotunda doodad and just compression test it.

 

C,
Thanks a lot for posting.

I'm trying to figure out an oil issue is the reason for trying to perform this test. Oil issue is, the compressor side seals (on a brand new center cartridge) with the crank case vent open to atmosphere and the discharge IC pipe removed are leaking. I know there will be some oil residue in there from the CCV. I have cleaning the oil out of the H pipe several times and I feel pretty confident that the residue has been eliminated from the compressor casing. When running the truck for a bit the oil slowly starts seeping out on the discharge side of the compressor. I ran a compression test on the engine a couple of weeks ago and posted my numbers on this tread.

Not the best compression numbers but not the worst ones out there either. I tried plugging off the CCV with my thumb today at idle. After the engine had ran a couple of minutes at idle, when I removed my thumb from the CCV you could hear the built up pressure escaping. My thought here is that, the crank case is building up just enough pressure hat the oil outlet flow from the turbo is being restricted and casing the seals to leak. I found in a ford book that 4" of water column is max using an "Ashcroft Gauge" (Name Brand) but it didn't specify a testing procedure. At this point, I'm running out of ideas. I'm trying to rule out, with testing, everything I can that would be causing the oil seal issue before I make any drastic decision.

Thanks again for the help.
