Ke30 4k Blow By

[Trent-KE30]

Hey guys, just been observing my corolla of late, and its got an awful lot of blow by, like when you follow me it smells like oil :D And the breather out of the rocker cover has got a bit of steamy/smoke coming out of it, btw its a 4K. I always thought this was slightly worn rings? Any queries?

 

Cheers Trent ;)

yeah this means that you rings are worn or bore polished. and the compression is getting past your compression ring and in to you crank case. might need rebiuld soon. 4ks are easy small bit of knowlege and tools and your sweet to do it. basic engine. good luck

Any standard setup has the breather hose going back to the air intake. And the PCV valve hose going to the base of the carby, which keeps the breather as a closed system, and you never smell oil.

 

Having a open breather will always give off a oily smell. A small amout of steam and oily vapor is normal. But if the breather puffs out oil like a chimney, then its time for a engine rebuild.

Oh ok, i knew it had something to do with worn rings.. I'm a 3rd yr apprentice at a engine rebuilder so i will get it out and take it in and rebuild it!

 

Thanks Guys :y:

 

Oh also there is an awful lot of oil coming out of the spark plug holes, i think its pushing its way out of the head.. I think i might put my old 3K back in it..

Pano has had a heart transplant in the form of turbo_rolla's old 4K from his KE70.

 

Now I just gotta get the gearbox working right. *sigh*

 

I put the wrong clutch fork in so the box has to come out again :y:

[Trent-KE30]

Love_KE70, I had a vague idea what it was if you read the first post... And where i am Tamworth NSW, i miss out on the TAFE Engine rebuilding course, closest one is in Newcastle, So i do Fitting/Machining and don't learn the basics about motors etc, because its mostly lathe and mill work.. And at work I got put on the machines, eg.. I grind/polish cranks, resize/recondition conrods, I got books and stuff to read but i'am too flat out lol...
