I personally use one of these which you can find in B & Q,wilko’s,etc and depending on how bad the muck is,decides whether i will apply it neat or watered down(neat…bad,50/50…so so,25/75…winter salt)but like you say,there is some caustic in there so rubber gloves is a must,and also be careful of the plastic items,it will clean up the manifold cover , rocker cover and thottle body to a like new look, i have the car on a slant facing forward with the engine running to help the drying out after you have washed it away with an hose pipe.
if you do this every year it gets easier because there will not be as much to get deep into???
Don’t forget to cover that coil pack ,when cleaning the rocker cover and rinsing off do not worry about the water that will go down the spark plug tunnel yet,and when everything has dryed off you will need to respray the moving parts with a bit of wd40 or the sprayers nightmare(which i love)silicone lube spray,only because you have just cleaned everything away,including a light dusting on the rocker cover and throttle body,and just wipe down,the only thing left is to undo the spark plugs one by one out and just let the little bit of water that has found its way down there drop in,and just check the ht lead and spark plug is dry before screwing back home again,now just stand back and look what you have just done…wow
Not everyone will agree with using TFR for this but the people i know that use this,and myself for some 20 odd years swear by it,and the owners that have dropped on my door( that now know my secret)will also give a big thumbs up and wow factor on collection.
Thanks to everyone for joining in my mindless guessing game simply for the fun side,watch this space and i’ll do another one soon,and well done chris and i’ll see you soon,and thanks andrew at autolinkuk.co.uk for your freebies,and charlie for being so kind to let me hijack his post.
Any questions just ask…you know where i am.
Kind regards
