Exclamation zs manifold cure

Ive recently bought a brand new inlet manifold and vis motors but i wanna know if theres anything i can do to prevent the rattle coming back. Ive heard of fitting a catch tank but all the ones ive seen all have the inlet and outlet port close together with no filter meaning big droplets will be collected but any fine mist is going into the manifold! Short of venting to atmosphere i cant think of anything else. Im not sure if you want a lil bit of oil coming into the manifold to lube the buttetflys would be helpfull. Sorry to.repeat threads i did search the forum but couldnt find the info i wanted. Any replys would be helpful cheers guys!

many end up removing the VIS motors and valves completely, theres lots of threads on removal

Apart from a oil catch tank I don't think there's any other options, I was thinkin of buying a brand new one and putting a catch tank on the big vacuum hose and leave the smaller one, personally I wouldn't want any oil going in there to be burned, but I've decided to pocket the cash and just rip the valves out lol.

Thumbs up

Well id bought several second hand manifolds over the use and they all end up the same way think ill just keep buying new ones normally get good 40-60k before they start ratting just hope catch tank does the job maybe even a in-line fuel filter. Cant say i blame you 465 for manifold and vis motors bank balance is hurting lol

I think the problem is the heavier oil getting through, the fine mist will help keep the valves lubricated.

Something to think about , my car is on the original manifold ( 9 years old ) the car has a catch tank on the small pipe , but its been run on fully synth 5w40 oil from 1000 miles , I wonder if this slightly thinner oil has made a difference ?

I opened up my last manifold seems like a mixture of oil and carbon. The thinner oils prehaphs not a bad idea. Its obv. Worked with your.
