Manifold cleanings
 

I did put mine in the dishwasher and it made a very good job of it, I had to run the dishwasher on a clean cycle afterwards though :D

Someone on here used Mr Muscle on theirs, it has no detrimental effect on the manifold.

I have also seen good use of original Ariel washing powder, used in a big tub and left to soak overnight.

There are lots of ways to clean them, I will admit that I didn't notice any difference in my car after it was done though.


Dirty job however way you do it, if you have a friendly local garage they might have a parts washer and might charge you a fiver or so for doing it.

Any of the oven cleaners will work ,
Get the one with the bag , leave it overnight , works wonders

Oven bag plenty big enough, I left mine overnight and then pressure washed it all out the next day, never seen so much black crud come out of an inlet manifold! that's what persuaded me to unplug the egr thereafter, definitely didn't want to do that again anytime soon!

I do this method, far easier than the spray on oven cleaner.

I put one in the dishwasher once, stained it with oil for months.

Or save yourself a messy job and contact Arctic for one he's prepared earlier - like I did :D:D.

Pretty easy to swap a filthy one for a clean one.

Please advise, s it necessary to replace the manifold seals? Thanks.

I did not when I cleaned mine
