Just redid timing after belt skipped. Valve did hit pistons, comptest showed that only number 2 piston was below (120). Car idling great, but was lacking some power. Then...

Today, I drive it to work, still no power. On the way home, even less power. Did notice a bit of smoke coming from ex. mani. after each drive.

ON the way home, the temp* is waving around, no power at all (barely make 40mph).

Get home and pop the hood:

1. Oil pool in valve cover
2. Oil on the hood heatshield
3. Oil shot out of the breather valve filter (on outside of IC pipe.
4. Coolant is bubbling in resevoir.
5. Smoking from ex. mani.
6. At full throttle, no power still, and boost still rises.
7. Timing is still perfect

I am really at a loss with this. All I can think of is either headgasket, rings on #2 cyl., or crankcase ventilation.

Recently, I have done the BS removal, new oil pump and case, changed all 8 intake valves, changed out old MAS with used one. REbuilt like 4 months ago, only problem from then was no boost, which was fixed.

What the F*** is going on??? (sorry for long post)

It sounds like your ring went on the piston, I had the same thing, smoke out the exhaust and breather valve would smoke. Then it completly went sounded like the car was a V8 and absolutly no power at all.

yeah man if a ring is shot the compression will get worse and worse and eventually start to mess stuff up, and the lsat thing you wanna do it just have it die on you when your far from home, change the rings but when you remove the piston check the walls and make sure they arent scratched or chipped especially on top of block where compression is cuz it could leak around the head gasket also

you put all kinds of pressure all through the motor although the pressure in the coolent is prob a sign that the head gasket let go at some point too

I"m surprised that 1 bad cylinder would cause all of this. What sucks is that my car is a daily driver, so my decisions are driven somewhat by time. Why, this time, I didn't do a wet test on the 2nd cylinder is beyond me. I assumed that the valves were bent on it. Thankfully, my bro got his own car, so now we have a spare that I can drive. I might just end up rebuilding everything again in the next few weeks. Gotta get my eBay business back and running so I can afford the stuff I want. Thanks for your input. More would be appreciated.

Any answer for the coolant boiling in the resevoir or could it be air being blown into it causing all the bubbling?

naw, the dipstick was still firmly in place. that's the first thing I thought, after I saw all the oil everywhere, I figged that I was getting some awful ventilation.
