Teardown leads to mystery?

[Slipstream]

I finished breaking down my KA just so I could carry it into my garage and shelf it. When I dropped the oil pan, it was full of metal and plastic chunks. I mean literally about a coffee cup full. The oil pickup was even packed full. Problem is, not one internal part was broken, chipped, or cracked. The car was burning oil when I decided to yank it, but it had no visible leaks. Not so much as a drip in my driveway. What gives? Disappearring oil, needed 3 quarts every 900 miles, and then what looks like my engine chewed something up? Anyone run into this?

Maybe your timing chain tensioner stuff broke?

[SD413Silvia]

WTF? Thats random... there shouldnt be any plastic stuff in your engine. check the tensioner as razi mentioned, if you're burning oil without leaks the only thing that comes to mind is head gasket. check your rear main seal also, theyre notorious for goin out.

[Slipstream]

Chain tensioner and guides were fine, so was the head gasket and front and rear seals. Only thing I can think of is someone had it apart before and didn't clean out the oil pan before putting it on. I'll have to get a pic of everything that was in there.

the plastic is from your chain guides, the burning oil is most likely from bad piston rings which is why your losing it but not leaking it. its getting burnt

It's there, just being retracted with that green push pin.

the chain guilds where replaced before i bet. im currently doing a repair on mine right now....pain in the butt...anyways. my bet is that they did what im doing...just not take off the oil pan when doing the swap out. you dont have to take it out to do the swap. so pretty much the guild was destroyed and fell into the pan and now sit there forever

why wouldnt you have to take the pan out? wouldnt you have to reseal the oil pan? looking for shortcuts, always

[biotoxic07]

im going to reseal the cover and install it that way. and ya i love shortcuts as long as they work, doesnt everyone? i mean that is why i play the lottery.....

That's what I was thinking too. Some of the top end had orange rtv on it, a good sign some work had been done, but the oil pan had the gasket and no rtv.

complicating this discussion is the fact the oil pan issue is different for s13 vs s14 and dohc vs sohc. 3 different scenarios.
