Hi all in the next day or too im want to strip off my breather pipes to clean all the old oil and grease etc out.Whats the best way to clean them. is there anythink i can buy to soak them in etc

wynns carb cleaner

[Entwood]

I found carb cleaner to be the best ... the fact it sprays as well seems to help shift lumps of crud ... so I sprayed, left to stand, sprayed again, etc etc..

Right well i cleaned them today i used carb clean like u said with a little brush that i can put down the pipes so now all nice and clean as there was loads of dryed up oil in them

[yorkshire ripper]

did you clean the metal pipe that runs down the side of the block ? passenger side rear as you look at the lump. mine was solid. also worth taking your sump off and cleaning the pick up pipe. again mine was solid, soaked it in thinners over night and it came up like new.

I find it salways worth doing the ICV at the same time.  If breather pipes are gunked up, the icv normally is too.  Pick up a new gasket (only a pound or two) before tackling though.

most garages use old brake fluid as it is an astringent and rips through oil guk like there is no tomoz

Way back when I used to dip all my parts for cleaning into a trike bath... those days are long gone now tho

Need a fume cupboard for that now. Didn't do me any harm. But brake fluid does work. Just wear gloves

Whats the ICV.No i didnt do that pipe going into the engine block.i`ll do that when i have some spare time but the car seems to go hell of alot better now iv cleaned the pipes

Its the idle (air) control valve, basically feeds air to the engine when idling so the car doesnt stall.  If your revs are all over the place when you stop, or it stalls often, or between changing gears (in an auto anyway) it normally is a sign it needs cleaning.

If you follow the air intake (the big black tube, has a breather pipe going between it and cam cover) to where it joins the throttle body you should find the icv under its silver metal, and to the right has a connector that looks similar to the one on the MAF.

It tends to get as gunked up as the breather pipes, with the same oil stuff.

There are a couple of guides to cleaning it on the site and this one is pretty complete
