Went out for a drive the other week, and it threw a CEL, I pulled over, cycled the ignition, and went to turn around and head home, when it decided to eject a spark plug out of the head...
Naturally I did not have a spark plug socket with me, or anything I could use really, and the coolant level was very low as well which concerned me, so I opted to just get recovered home.
RAC sent someone very quickly, was very happy with them!
The offending ejected sparkplug. Apparently these engines
can vibrate the spark plugs loose if they weren't torqued correctly.
Removed and inspected all the plugs, re-set the gaps as they were a bit off, and torqued them to spec.
I noticed while I was in there that the rocker covers were leaking a little, and the bolts were a little loose, so I torqued them to the factory spec.
Which then caused this... Phooey!
So I whipped the cover off...
This is a common problem apparently, they are made of cast aluminium and are quite fragile.
Got it welded up by a local friend...
Lovely. Its covered by an engine cover so no need to dress it much, rather leave the full weld bead for strength.
Re-installed it, but not before noticing this on the driveway... That is where my coolant was going. All over the floor.
Pinpointed the leak to this coolant bypass pipe behind the water pump.
Got the bits... (didn't need the bypass pipe but got it just in case)
O rings a bit flat, and some corrosion in here...
Cleaned up...
Fixed!
