Behaving badly

[Duquette5]

Yup - spark plug tube seals.

So it looks like 1,3&5 (drivers side are the odd cylinders correct?) have been leaking slightly for a while now. 3 & 5 finally gave up today. Ordering them now and will do all 6. No sense in tempting fate. Never a dull moment!

Bin there done that. Nice clean motor now with no oil smell after every drive
This will give you a chance to prove your inventiveness for creating a tool to remove and install tubes

While this does account for smell and smoke sort of (If leaking oil was getting on exhaust)
it doesn't account for bad engine behavior
