Hi guys,
Removed the rocker cover yesterday and had is sandblasted ready for paint. Put the cover back on and all runs fine until a few hours later when a rattle-grind was coming from the engine and then at idle the engine warning light would flicker on and off. What could this have been caused by? The oil level is fine so I’m worried there is still left over sand in the engine?! There’s also white smoke coming from the engine bay also? Could anyone give me some suggestions on what it could be and how to sort it, thanks!!
UPDATE:
Since having a misfire I checked the plugs and I’ve got oil on all four plugs. Clearly the spark plug tube seals have failed so I’m replacing them and getting new plugs. The warning flickering light was most likely the lack of pressure because of the leaking seals. So for anyone taking of the rocker cover, REPLACE THE SEALS!! DO NOT LISTEN TO A CERTAIN TUTORIAL THAT SAYS YOU CAN GET AWAY WITH IT, CLEARY NOT ALWAYS YOU CANT SO BETTER BE SAFE THAN SORRY!!!
