Hi, I want to spray off general salt and grime from my engine. I won't use a high pressure lance, it will be a hand pumped sprayer. I just wanted to know which parts I need to cover with a bit of tin foil before I begin. Do these engines have a distributor cap ? I know the air intake sensor needs covering. Please advise. Thanks.

Tin foil??? You will end up shorting something out with that.

Cover electrical connections/plugs and the fuse box with plastic bags and spray the bits that dont look electrical.

Spray over on light spray setting with hose pipe.

I use Meguairs engine cleaner spray on and leave to soak for five mins

Agitate with a alloy wheel brush and a soft detail or paint brush for the tricky areas

Spray off lightly

I use Meguairs engine dressing spray on liberally shut bonnet for 10 mins

Wipe down with microfibres cloth and start engine to dry any hidden components

I use the jet wash on it about once a month. No issues at all.

same here.

Distributor cap?  On a diesel?????

Modern engine bays are so much cleaner.  Can't be bottomed any more.

But when I was, a jet wash with the lance held quite a distance away.  Then a good blast of dispersant, then immediately start the engine and go for a drive to evaporate any lurking moisture.  Take your tin of wd40 and a wiper with you just in case.

Should you get back OK, open the bonnet to let out any residual vapour and mop up any puddles remaining.

I prefer my engine to be dirty and greasy, the best anti-corrosion resistence there is!

 

After all it's only ever me and the local Skoda dealer that see's it.

Soooooo, where are the spark plugs then, clever clogs

Id have the engine running whilst you clean it then give it a run round the block to dry out the engine bay & electrical connections.
