Also check between exhaust manifold and cylinder head.

 

I haven't done the boost leak detector thingy either, but I've always had the same question? How does it work, from either end, since there's most likely gonna be at least one cylinder in valve overlap? If you plugged the CCV and the exhaust pipe, couldn't you boost test the whole thing in one shot? Or is there a limit to how much pressure it should hold before something begins to leak anyway?

 

I don't know what the threshold is but I suspect that too much pressure locked up in the crankcase would blow a seal or two. Mine did pass air somewhere when I conducted the test but I couldn't figure out exactly where it was going. like you said not all valves are going to be closed. I applied about 30 lbs constantly to the intake and sprayed soapy water on the places where it could leak. I had none so I figure I'm good.

 

If you block off the CCV line, then there shouldn't be any air going into the crankcase. (Edit: I suppose there will be some piston ring and valve stem seal leaks depending upon the test pressure. Possibly some through the turbo as well) Leaving the oil fill cap off would prevent crankcase pressurization and also provide feedback letting you know you have a leak into the crankcase, stick a latex glove over it and see if it fills up.

 

The common practice is to remove the plastic collar that the CCV connects to and install the tester in the turbo inlet tube. If you do successfully block everything off it would be interesting.

 

Look at this Byron something that might be of interest.

New 5th


Pickup day


Long day of driving


Temp home next to previous 5th

 

Happy Saturday all you infadels....life has been happening fast. Good to be back home and moving forward....WITHOUT snow, ice, and wind.

Wes, what a score! You did great work on the truck too. Hope everyone else is good and life is holding you high....er, something.

 

 

Thanks Brian. Check out my clutch thread for review on that turbine

 

After this past month I'm starting to get tired of wrenching Fun every now n then but not daily. Wife's van threw codes for o2 sensors on 3 hr drive home Sunday night. 4 of those stupid things on that 6 cylinder. Now it has the underlying problem code, with a TSB on it for the software update that was done on it recently. Back to the dealerahip again. Can't remember if this makes the 8th or 9th time there since Dec 20th.

Guess I'm starting to know how those 6.7 guys feel

 

I feel ya....big gasser is next for me. I've had 7.3s for years. I'm ready to not work on something for awhile.

 

"Hi guys, how do i supercharge this fuel hungry V10? And i want more than 4mpg towing heavy"

 

Oh man, I didn't expect that, Byron, that's quite a change. Will you stay with Ford? I've read fleet owners prefer the V10 for it's much lower cost over the life of the truck, both upfront and maintenance. But what about the torque, the noise, the stink? Everything we love about these beasts.

 

I'm in the same boat as Byron. Right now, I'm thinking either the 6.2L F250 or perhaps a Tundra. I'll dig further when it comes time to pull the trigger. Every year, I keep saying "in about another year", but I KNOW that I'm getting closer, and it may just be this fall after the '20's come out.
