My old merc could do with a good clean under the bonnet - years of slow oil leaks have given it a nice coating in the bay…any recommendations?
I had a coolant hose burst on me in the Saab a few months back. That cleaned the engine nicely.
I’d like to do this to the old girl too but in all honesty I can’t be bothered.
Would certainly help with diagnosing where the new leaks are coming from!
