Using a qt. every 200 mi. If my tpi intake was sucking oil from the galley would I be able to tell looking into the injector hole with a bore scope?

 

Maybe... you could look to see if the gasket is folded up into the intake port. The oil itself might or might not show up.

 

What heads? Sealant on rocker studs & studs tight?

 

It could be sucking oil there at the intake flange or even at the rocker studs holes.

 

If its a motor you put together w/ different heads then you might have a mismatch somewhere, I had a similar oil burning problem. I had to buy a felpro 2520 checker to figure it out. Basically the heads were to high. Which causes the mismatch at the intake flanges. I had 20 taken off the heads & ran a thinner head gasket. Sometimes using thicker intake gaskets help too.

 

Was a felpro steel cored intake gasket. Dart SHP heads. Did not seal rocker studs. Hard to believe oil could get by those threads

 

I thought the same thing on the rocker studs, till I pulled them & they had a coat of oil on them. On my heads, some of the holes go through to the intake port. Plus each time the rocker opens & closes the stud flexes slightly & the ones that are under engine vacuum are the worst.

 

Interesting about the checker. Took about .020 off the block as well.

 

IIRC all the intake ports had a stud hole. With the dart lengthy disclaimer , would have thought they would have mentioned to seal them. Could that much oil get by the threads? Should try that first before I pull the intake.

 

Yes, I would check that first. Might want to pull plugs and see if they are all contaminated and if only a couplecheck the studs on those and cross reference by checking a stud on a clean cylinder. If they re slightly loose the oil consumption gets bad really quickly.

 

Big mistake.

Not sure how much "that much" is, in your opinion; but, ALOT can get by there.

Vacuum on one side, crankcase on the other.

Go back and fix that mistake. No sense in "troubleshooting" any more with such a gaping mistake as that.

Use the Permatex "high temp automotive thread sealer with Teflon". NOT any kind of silicone, or gorilla snot. Both dissolve in gasoline.

 

Some of the plugs are worse than others. The fouled section of the plug is pointed toward the intake valve. Maybe just seal the intakes? The studs are all torqued down tight. Any sealer better than an other?

 

Seal them all. Why do it half-a$$ed when you're ALREADY in there ANYWAY and it basically doesn't cost another dime?

Not sure about the sealer question; maybe one of the posts farther up might shed some light on what to use and why not to use the common substitutes.
