I recently pulled the engine out of my 1967 ALFA - the first time it's ever been out.
You can imagine the amount of dirt, oil, grease and other crud embalming it, the gearbox and the engine compartment after 100,000 miles.
I found a bottle of Power Dissolver in my garage, spayed it on and couldn't believe the results.
The Dissolver cut through it like magic.
I hope I can find a comparable product.
