Showing My Ignorance.

[KE30Coupe]

OK time to show my ignorance for all things mechanical. I've got 3 holes that I don't know what to do with (keep it clean :dry: ) I've attached the pics with arrows showing where they are. When you all have finished laughing at my total lack of knowledge and have composed yourselves please advise what to do with them or what to attach them to.

 

Thanks

 

Oh and its a 3k in a KE30 that still needs a lot of work :sad:

the hose in the middle of the tappet cover goes into the stock air cleaner, it's a crankcase breather, but being hooked into the air cleaner (not very strong vac source) it doesn't do an awful lot. if you have room, you can put one of those trick little chrome filters on it, i used to have one of these. i recently got a 10mm rubber cap and blocked it off

 

the hose on the end of the tappet cover is for the pcv valve. there is supposed to be a piece of rubber in that pipe that the pcv valve goes into, a hose then goes from the valve, to the sandwich plate between the carb and the inlet manifold. if you've lost this piece of hose, you can use normal 8mm fuel hose. you could also hook up a catch can to this pipe, i'd still have a hose sucking from the sandwich plate to the catch can though

 

i don't recommend running without a pcv system, you pollute your oil really quickly (<500km), and if you leave the hole uncovered it will make a oily mess all over your bonnet and tappet cover

 

the pipe on the tappet cover is part of an early K motor emissions system (i believe -H motors?), it originally connects to a three-pronged valve which you may or may not find still present on the engine block, just rearward of the distributor. the valve vents the front of the crankcase to atmosphere when the engine reaches a certain temp, or when certain vacuum conditions (probably what) exist. don't worry about it, it's a waste of time, block it off. i had one of these on my old 3k, i blocked it off with a piece of fuel hose with a bolt in it. these day's i'd get a classy looking little 6mm rubber cap and put that on there

 

you can see here my 3k with the timing cover hose blocked. i had little foam filters on the tappet cover at this point. big mistake.

 

here is my engine bay at the moment, i'm halfway thru a carb install, so i don't have the pcv hose hooked up to the manifold at the moment, but that will be an easy task

number 3 on my old ke30 went to the fuel tank vent hose.
