CaM 0 Report post Posted August 22, 2006 engine breather? figured that would be an easy diagnosis. To stop it - oil catch can system Quote Share this post Link to post Share on other sites
bravo 34 Report post Posted August 22, 2006 Bit of blow-by. Worst case scenario is rings/valve guides, but could be small vacuum leak, or blown headgasket f**king with pressures inside the engine. I had it - would always blow blue smoke on startup as the oil burnt off. A good clean out of the intake system, and checking of all valve clearances, hoses, gaskets solved the problem.

325GRANT 0 Report post Posted August 22, 2006 i just got a catch tank from a guy on trade caled sinco1. he made it to my specs, did everything i wanted and suggested some other mods that might help. his work is awesome, arrived in 3 working days and cost $110.00 delivered. looks like the one in photo but with different size inlets. i will use this guy for any of this sort of work i need from now on.

Gus 5 Report post Posted August 22, 2006 its pretty normal, there prob nothing wrong with your engine the oil breather is the one come from the rocker cover to the throttle body. bout an inch thick or so Quote Share this post Link to post Share on other sites
CaM 0 Report post Posted August 22, 2006 yup, euros seem to love blowby. Am currently sorting a catch can for my pug, for this reason. gums up the idle port in the throttle body, etc Quote Share this post Link to post Share on other sites
nz320i 0 Report post Posted September 6, 2006 if i got a catch system ( purely for riceness/looks ) where does the other tube go to, i guess one comes from the rocker cover?? where does the other go to? Quote Share this post Link to post Share on other sites
325GRANT 0 Report post Posted September 6, 2006 you would prob only need one inlet, i used two because i modified the breather from my sump link to my set up Quote Share this post Link to post Share on other sites
kerrynzl 3 Report post Posted September 6, 2006 BravoMike's answer is correct, the crankcase is pressurising because of Blow-by [cylinder pressure leaking past the rings] BMW's do 100's of 1000's of K's without a problem. when this occurs the motor will be tired [RE-RING IT] If you're selling it [old car shark trick] , make an oil separater by jamming some 'Goldilocks' steel wool in the breather line [don't jam it in too tight, you should be able to puff thru it with your mouth] Remember your Crank Seals will be as tired as the Rings Quote Share this post Link to post Share on other sites
