I can't - but any on the manifold or below the carb will do.
From memory there's one for the breather system (on the back of the manifold, below the carb?) which you could remove, attach a short length of hose in its place for the purpose of conducting the "Chinese Water Torture", then replace it when you're done. cheers James

As I recall you held it at 3000rpm whilst I did the dipping of the pipe in the water. Something to do with you refusing to take responsibility for blowing up your own engine and feeling much better if someone else blew it up and then had to pay for the repair......... Anyway, the point is that it worked and made the car much more driveable, idle more sweetly and generally run sweeter. It is definitely worth doing, but be careful - only small amounts of water at a time and for short periods only. |

Just one last question - can I dribble water down the hose that connects from the top of the air inlet to the PCV valve? If I can - then I think I've finally sussed out what I need to do and where!

little report, car running sweeter than ever, 'ran on' twice out of 10 stops, whereas it used to run on 9 times out of 10. So improvement but still not perfect, but proof that it surely works! I only done it for 5 mins twice. So probably a 15 min session would be perfect.

I can confirm that this works well. I learned it 20 years ago on my first car, a '65 Corvair. It was an 'old lady' car, and this trick is a good first step if you're buying a car that had only been used to go to and from the shops. Because the Corvair was a downdraught carb, I used our old coke bottle with the 'sprinkle' ironing end to drip water so that I didn't get too much in there. My dad's white Corolla was parked next to the exhaust, and was covered in soot! oops.
I've also done a redex decoke on a 2 stroke engine. What that involved was pouring redex into the engine through the spark plug holes. Turning the engine over a few times with the plugs out to coat everything and pump out any excess. let it sit overnight, turn the engine by hand slowly to make sure its not locked, then start up, making sure there is nothing valuable (like one's father's car) next to the exhaust. This is best done at night, when the neighbours can't see the cloud of smoke. |
