Trying to stop my oil consumption. Truck has used oil since i installed it from the junkyard. Don't see it leaking anywhere when its parked or running. Pulled plug number 3 and found this on the threads.



Did a compression test on that cylinder.



Put new valve seals in and it cleared up the visual smoke. Any ideas on this. Its probably using 2 quarts every 600miles. Been beating the snot out of it. Crankcase is vented and intake is blocked off.

 

What kind of breathers are you using to vent the crankcase? Pics of those?

 

I can grab a pic tomorrow. I've just got the valve covers ran together and a SBC vent in the oil fill cap.

 

Is it just that #3 cylinder using oil ?
All the others look good?

Could be valve seals bad.
Oil ring stuck
Or sucking it through the PCV into the intake track

 

how does that compression reading compare to the other cylinders? do you have access to a leak down tester?

 

Got my plugs out. Planned on switching to br7s and doing a compression test. Well, my compression gauge took a crap, so I'll have to get another one tomorrow. Here a some pics of the plugs. Basically, there is oil on all of them.

Cyl 8,6,4,2


Cyl 1,3,5,7


Cyl 8 at the top right, cyl 1 at bottom left. In order

Makes me think its coming through the I take now. I'm running 2 of the same valve covers with the oil fill caps. One cap is vented. Both of the hoses are teed together on the valve covers. Intake is blocked off at the throttle body vacuum port and at the pcv port on the intake. Anything I'm missing? Don't really think its the turbo seals. It burned about the same amount of oil n/a and I had some of the intake piping out around 2 weeks ago. All looked very clean.

 

What gap are you running? You might want to cool down a heat range. The black dot on the porcelain of the #1 plug in the last pic can be an indication of too hot of a spark plug. Do you have flow matched injectors? Make sure you retighten the plugs after a couple heat cycles.

 

Those were .035 gapped tr6s. I've got a br7 I'm going to be putting it. Thing the Inejectors could have to do with the varied color of porcelain on the plugs? Also found a pretty burnt plug wire on #7. But t around the boot pretty heavily. Does it even look like #7 was firing?

 

You guys and all your cold plugs make me crazy. BR7'S ??? I rock reg 55's on a bit of boost. What makes this 7 so good? Something else going on IMO

 

your best bet is a leak down test, not sure if you have done that before but its a bit involved, it will let you know condition of your rings, usually 10% leakdown through crankcase is the norm, more then 15-20% and you have ring problems
