oil in inlet manifold ?

As per title i took the inlet off last week to be powder coated

just noticed today that the inlet looks to have a little oil inside the port, the one on the driver side closest to the bulkhead (number1) i think

is this normal or could it be cause for concern, the rest of the ports on the manifold look ok and clean

Any help appreciated

Normal, the oil gets in to the manifold due to the engine breather system.

A small film of oil will be ok, if it's dripping wet then you have issues.

Sounds like it's ok then, it's only a small amount to be fair nothing excessive, just thought I beat check first, is it best to give it a clean before refitting or would you not recommend it

Yeah i would clean it out, wont harm. I would personally use some brake cleaner or petrol and maybe a pipe cleaner to get into it abit better.

Spot on I will do that then cheers

That's what a catch can is for, it's normal and ok at lower powers but from what I've read, it can cause problems at higher powers

Maybe worth just checking and cleaning the breathers to while your on. Wont harm any.

Ah that makes more sense to me, I'll give the breathers a clean to before I re assemble what's the easiest way of cleaning them?

I think I'll invest on a catch can anyway, I know it's not nessacary but may aswell, plus it's getting mapped soon so should help a little

Ideally a 3 port catach can but a cheap 2 port with breathers 'T' together will surfice.

Can you link me a decent 3 port catch can as I can only seem to find 2 ports?

Stupid question what the difference between the 2 port an the 3 port

your engine has 3 breathers, one on top ov each cylinder head and one from the bottomend (crankcase breather)

so a 3 port catch tank can have each breather going straight too catch tank.

where a 2 port one would require you too T , 2 ov the breathers together..

Cheers for clearing that up, would I be ok with a 2 port one then? Will it do the same job

yeah will do the same job, and less pipe work tee'ing pipes together
