Gold-Car had 200+ compression in every slug..Still possible rings?
Im thinking its the valve seals. how many miles on the motor since rebuild ?

Yep motor needs to come out. easiest way since timing has to be reset etc

Just replied to you in the for sale section..If you give me a couple days,I could dig up the receipt with the specs..When I bought mine just recently,,the fronts are readily available on EBay..Same exact ones for Trans Am/Camaro..The rears I had custom made from ARE as ZR1 offsets were discontinued long ago and no supplier anywhere had left over stock...They made my rears for $300 each..

Thank you.

What kind of advice have you gotten from Marc or Arron on the oil consumption?

Haven't spoken to either of them on consumption..Only spoken to Marc on tuning issues...I think it's safe to assume that constant tailpipe smoke is not normal..

Not normal for sure....something bad wrong? Not convinced, I'm leaning heavily on the side of valve seals.

Almost sounds like it has too much pressure and can't breathe.

As far as I'm concerned if the the motor needs to come out,,that's bad..If I were to have it pulled,believe me it would get torn down and fully rebuilt..I did speak to Marc on rebuilding as a worse case scenario..He wants 9K to fully rebuild to 368 specs..That's even using my liners and rods..Then another $800 to dyno tune it..Then whatever other problems he may find..On top of that its probably gonna cost an additional $1500 to get it there,return home,then back again to get it..I love the car..But not that much...


To much pressure,can't breath?..What kind of pressure?..here's my take..It can't be too much fuel..Car has no gas in crankcase,starts easily...Car has strong compression and plenty of pulling power,no blowby from oil cap or dipstick..Rings seem good..Only thing left is PCV which I triple checked for obstruction in every tube..Non found..That only leaves valve seals...

Are they next to each other? What modification had been to this motor is anything?

Im certainly no LT5 expert but a broken ring or big problem would be causing drivability issues one would think.

It may be worth your while to call SGC and see what they recommend.
