      hahaha, good post. Yes, another guy learning the hard way. If you don't meet the octane requirement 100% of the time you'll be sorry. And might STILL not know what happened. Call ME people before you start guessing your butt off like this guy did. The Edelbrocks and the right cam have MUCH more potential than this. Over 6000 sets done at my shop.

    The Pontiac we raced in Stock Eliminator had a beat adaptation. We ran no dip stick, we used the PCV system and no valve cover breathers. We also had a pressure/vacuum gauge going into the valve cover that showed lots of vacuum in the engine at idle but zero through the traps at 6800. When we started losing the low tension rings we saw pressure through the traps and did a "Freshen Up" before something went south,

  • @JordieG8
    @JordieG8 4 ปีที่แล้ว +2

    Rich! What you describe is called pre-ignition. Detonation is a secondary ignition even that occurs after the spark plugs fires. The result is 2 flame fronts that increases the rate of burn and spikes cylinder pressure before the optimal crank angle. Both are bad, pre ignition is generally worse and it's less controllable.

    Time to leak it down. Is that distributor locked out? Cranks like it has lot of timing on start up. Check your timing or put a curve kit in it.

      Because E85 is ~115 octane and you can make much more power than any other pump gas you're going to get. More compression, more timing, more power, runs cooler. No downsides. $1.50/gallon race gas.

    The big problem with Pontiacs and blow by is when the pressure starts building the rear oil pan seal starts pushing out. Eventually the pan seal will push out all the way and make one hell of a mess under the car, as soon as the oil gets to the headers via the torque converter all hell brakes loose. Make damn sure the flexplate cover is on the transmission.

    Not a bad engine either, I've come back to domestic recently and have been building a Turbo 4l AMC Inline 6 for my AMC Eagle SX/4 4WD coupe. I've done what a lot of people don't like and kept the SX/4's height, technically dropping it a tad with new suspension, and have gone with trying to lower my center of gravity and making a great offroad/rallycross grassroots car. The 4l I6's aren't bad for power either...if you basically just replace the head entirely :|.

      The rings lost tension. Don't waste time measuring since there's no other option but to replace.

    @kevinsoderblom4348 4 ปีที่แล้ว

    Just a thought, it might not be rings but instead be tapered cylinder walls, so you get good compression, but at BDC its blowing past the rings.

  • @wrfarms9741
    @wrfarms9741 4 ปีที่แล้ว +1

    Hope you installed a a good bit higher/longer duration cam on the engine rebuild to break up and overcome the higher compression ratio at start-up. Plus it makes for a real nice mid & high range boost in hp & torque. Looks good! 👍

      Sounds like the starter is fighting too much timing, not compression.

  • @wdixon27
    @wdixon27 4 ปีที่แล้ว

    ya keep a lil more of that air in the cylinders and it outta make a few more hp, sucking the excessive blowby back though the intake with the pcv system will lower the effective octane via oil contamination, a catch can/separator/check valve may be an option to dump it into the exhaust for short term reduction of stink/embarrassment/mess

  • @davidrusso4750
    @davidrusso4750 4 ปีที่แล้ว

    My definition of detonation versus the charge burning it that the flame front in detonation MOVES faster than the speed of sound (~ 767 mph at STP). That is why you hear engine knock - the flame front moves with a sonic boom. The problem is that a flame front moving that fast is HOTTER than a burning flame front and thus things begin to melt.

    Your content is so diverse. I guess as a result of trying to get your channel off the ground. Anyway, this isn’t my favorite build but this episode was great. There has never been anything as exciting as the Audi. It was just so oddball and genuine and slightly foreign to us Americans. I know you feel the same way. You were more excited than any of us. It was a real roller coaster. Bring it back out and race the thing.

  • @ThePaulv12
    @ThePaulv12 4 ปีที่แล้ว

    re the blowby, unless the motor has been majorly overheated it is unlikely the rings have lost tension.
    My bet would be if it has tapered rings in it, one or two of the top rings are in upside down but it's just a guess.

      Ring gap(s) and piston load during cam BI kinda crucial. btw, what was timing set on during BI run and the metallic chatter, conv/flexplate bolt lengths? Pont always ran warm imo, also, what is the stochio on it with that induction setup?

    What's all that smoke?? Hate to say this fellas (from a Pontiac guy) You've got a broken ring or two, preignition the cause! The ring static pressure will be zero, but the engine will (inexplicably) still develop near its full hp. The crankcase develops pressure at full throttle... and the dipstick pops up.
    I've rebuilt five original (running) GTO engines with miles on them... all of them had the same problem, broken rings

    they came with 360hp stock, and you could drop in a 390hp 428 bone stock in 1969, iron intake, Qjet carb, point ignition, no porting. you gained 60hp, and a lot of blowby. was it worth it ?

    • @mattspontiacta
      @mattspontiacta ปีที่แล้ว

      428 poncho with 390 hp would not be worth dropping in unless he destroyed the current 455. Edelbrock heads while much better than the factory iron heads in my opinion are not worth the cost at all.
      Before I would spend 4K on E heads, I would go LS . I also run a 461 ironed headed stroker in my 81 TA . It dynoed 330 rwhp and 440 rwtq. Runs good for what it is. If I build another for the TA it will be a 6.0 LS
