Re: Engine issues

But I did a compression test on all of the cylinders, all hit 150-160psi but one. The center one on the drivers side put out 30psi and had oil all over the plug. Now I know what I have to do.

Someone NAILED that one on the head...

I still don't understand how the smoking got worse with 5w30 and then cut back a lot when I added Lucas oil treatment. Granted it got bad again, but it still seams odd to me.

Re: Engine issues

What is the sensor back by the distributor? I broke it and need to get a new one.

Re: Engine issues

Knock sensor screws into the block. The other sensor that screw into the stand off oil is the oil pressure señor for the Gauge cluster.

Re: Engine issues

The one I broke is on a 90 degree bend and it's a cylinder shaped.

answer to... more smoke, less smoke, more smoke. some oils will smoke more than others. It is an old USED CAR SALES TRICK. If the car smokes a-little. change the oil to a heaver grade or change it to synthetic. if your car smokes a-little with 10w-30 (lite grey) . it will not smoke enough to see with synthetic (very lite blue). that is unless you have a very big problem. like my old Mitsu GSX only smoked under boost. it was the turbo. it had a cracked waist-gate and bad bearings. It sucked the oil right into the exhaust and caused one hell of a SMOKE SCREEN.

Re: Engine issues

I had same issue couple of months ago, smoking and blow by out of oil filler tube. Do compression test. My findings for my old motor were not good. This is #1 piston, all the others OK. I hate to say this, but probably better get mentally prepared to spend a few thousand.

The pic doesnt show up in the quote above,but this is exactly what happened to mine. Ive only pulled the head off so far, but I can see the chunk missing, and there is no wall damage either. But since my 2nd kid is coming very soon, I need to get this thing done asap. So those new DART coated JE pistons are going to have to wait until another blow up, knowing my luck, thats not too far away!
