Setup is a 83mm Bensons sleeved, Earl Laskey assembled LS block. Eagle rods, CP Pistons and rings, ACL bearings, and new oil/water pump/timing belt.

Approx 2000 Kilometers (1250 miles). No boost whatsoever for the first 800K then 15 PSI since with Hondata and 720's.

I removed the PCV valve and plugged the bung from the manifold, so the block can breathe under boost.

Also, the valve cover breather is a hose running to the ground.

At idle, I can see the blow-by coming out the valve cover breather, and after a hard run, my hood has a fresh coating of "rustproofing: LOL (it comes out the hole where the PCV Valve was originally installed and blows right up to the hood.

Is this normal?

might wanna do a compression check, and check with whoever tuned it and make sure they didnt dick up the tune.

was the car tuned rite after u got the block or did u wait 500miles and then tune?

Put back the pcv. I can almost guarantee you that the crankcase blowby will go away.

did you read this? https://honda-tech.com/zerothread?id=878397

Absolutley. He built my motor. I started it up with a wideband, and it was bouncing from 14.5-14.9.

I drove it like that with no boost for 500 miles (800K) and then tuned it to 15 PSI. There was hardly no blow-by at all on the dyno, but it's been getting worse and worse by the week since.

Not a happy camper.

whats ur compression looking like?

if you read the whole thread ... earl said to tune IMMEDIATELY! not to wait X amount of miles. read the thread again

do a leakdown and let me know the results. if it is smoking, a ring or piston could be hurt. tuning first before break in is so critical, even without boosting. too rich can be as bad as too lean also.

spark plugs.

man o man....i did the EXACT same thing even down to running to hose to the ground to hide the smoke. it's gonna get worse...MUCH MUCH WORSE. it was my rings and i ran it until they just gave out and the car wouldn't turn over.

The tune was fine. I had a wideband on it since start-up. Numbers were perfect.

After the dyno, numbers were pretty much identical, and under WOT boost, it hangs around 10.8-11.4.

Head comes off this weekend. We'll see what's going on.

i would check compression first and then leak down befor you go riping things apart.

Did you remove the pcv after, or did you never have it since the beginning?

Turboteggy

It was hooked up at first, because there was never any boost to the motor.

It was disconnected on Dyno day.

Why dont you just try putting it back and see what happens. It cant hurt.
