Nah, they won't work. Pretty sure only e70s fit

Blow by is essentially combustion pressure getting outside the combustion chamber by any way other than when the exhaust valve opens. Usually in older engines this is caused by rings that are worn and letting combustion pass, though it can be caused by leaking valvese.. Remember you will also ways have some small amount of blow by as rings aren't a perfect seal (which is why there is a crank case breather, but it should be quite minimal on a good condition engine. With the engine running, pop your oil cap off and feel how much air comes out. Best case at idle it is minimal, i have had engines that have so much blow by that when you take the oil cap off they just about stall. Also if it were me, id put the crank case ventilation back to stock and get rid of that catch can thing. if you have that much blow by you are better off burning it rather than trying to contain it.
