I took my car out to the strip on Sunday trying to break 11's. Well first pass I hit 12.5 bogging second pretty bad. Second pass same thing but once I let off the motor was nocking and smoking some. I drove it half way to the pit area and then I decided to shut it off. I pushed it the rest of the way back. I pop the hood and my oil catch can was smoking and had overflowed and spilled oil everywhere and there was smoke coming from the valve cover breather too. I pulled the plugs and #2 was covered in oil. What does this mean? Ringlands went pushing all my oil out and possibly starve the motor spinning a bearing to make it knock? I wont be able to tear it down for another week to see the damage but I want to know what to expect.

 

well... not sure is will answer the oil on the sparkplug question, but my oil catch can was overflowing because i had an extra quart of oil in there.

 

mine was just below the top mark on the dip stick before the runs and after it overflowed it was below the bottom one so thats about a whole quart it pushed out.

 

mine fills up pretty quick at the track..

 

Where do you guys have the catch can hose's plumbed into?

Mine was filling up and over flowing in probably less than 1/4 mile...Got rid of the rear block barbs and used the valve cover approach..I haven't gotten anything in my can yet

 

do you have a drain back? is the can baffled?

 

I dont have a drain back on the catch can. I rigged up the can myself and put a luffa thing in it as a baffle. The engine is making a lot of noice and knocking but not as loud as a rod knock though.

 

anyone else have any idea of what the knocking is?

 

when does it knock? what rpm/ does it go away? is it rapid? slow? etc.

 

it doesnt go away and it does it all the time and rapid. Its more like chunks of metal rattling in there. Its not hollow sounding like rod knock but that could be it too. I started it after I got home and lots of smoke came out of the breathers.

 

I used to have that same problem in my car with the endyn catch can. I upgraded to the T1 Race Development catch can it it solved my oil puking problem. http://www.t1raceparts.com/pro...n.htm

 

Sounds like a spun bearing. Do a leak down test and see if your rings/ringlands are gone.

Thats what I thought as soon as heard the knock but I looked at my oil pressure and its normal so maybe its something else came loose. I am taking the head and pan off tonight. Sucks cause its a brand new motor.
