Thread: Running out of ideas..

Motor just newly built and we did the start up. Motor fires up right away, set the tps,timing,fuel pressure and let it ran at operating temp. Did rev the motor a couple times and motor sound healthy...
The car is not drivable yet but I'm almost done. But recently when I started up the car I noticed she was smoking..white...not coolant though.She's not overheating....I checked the sparkplug holes and I noticed there's oil in it..looks like it's coming from the rings but all 4? I did the compression test and made 165 all across. I did the leak down test and they were all good...Also did the pressure test in my radiator and it's good ..

Any thoughts on what it can be?

Set up
Cp pistons 9:0.1 cr 87mm
cometic head gasket
arp head studs
Jwt ecu
720 cc injectors
Z32 maf

Could be bad valve seals.

Hmmmm...the seals are new..they replaced that when they did the valve job but I was thinking about that too...thanks

Dumb question .. are you talking about oil in tbe spark plug holes prior to removing the plugs ?

I removed the spark plugs in the holes and looking inside you can see oil on the pistons. My valve cover gasket is not leaking oil..

What were the numbers and leak locations on the cylinders?

10-14 % they're all pretty much close and leak that you can hear were coming from the block breather or oil dipstick..which i think that's normal..

If it only smokes when you start it, and then nothing as it runs, then I'm thinking valve seals.

No, idle smokes and when you rev..more smokes...

I know everybody will think even me thought about that..that maybe it's the oil rings but why all four?

Sometimes it's an issue with break-in, or a bad hone job on the cylinders. There's a chance it will go away after a bit of driving, but I wouldn't count on that.
