Pressure wash engine bay before valve seal change?
Getting ready to swap out the valve spring seals on my 02 JGC Overland 4.7L HO this weekend. 334,000+ KM. Smokes after engine comes up to temp at idle, blows a bit of smoke when taking off from a stop sign. So I ordered the tool from Happy Hank on ebay, got new FelPro valve spring seals and valve cover gaskets, new sparks plugs... got the 12" spark plug hose to insert air into the chamber while pulling the springs. My question is.... " Has anyone cleaned the engine bay with a pressure washer before doing major engine work?" Any tips helpful. TIA
