You guys know your stuff. Thanks. I worked through the list above and sure enough oil in the plug bores around the coil packs on both banks. So where next. I guess new cam cover gaskets. I heard somewhere that the breather system could be a cause. Checked the pipes entering back of plenum and all seem fine. Pointers please.

Oil in the plug bores is a service job, it isn't the cause of the engine not cranking. Fix the more serious problems first, by doing one at a time.


When you've done that, there is a guide for dealing with the entire breather system - not just the pipes - which should be done as part of changing the cam cover gaskets.

Engine should always crank when you turn the key. Put the lights on and try it. If the lights dim but the engine does not crank, suspect the starter. If the lights do not dim there is not power going to the starter, suspect the starter relay, which sits on top of the starter. Check if there is power going to the starter relay to pull it in when you turn the key (smaller lead to starter).

If there is power to the relay when key is turned but starter does not crank, fault is in the relay. As the relay comes with the starter, again you need a new starter.

It’s all stripped down now so can’t test the starter but- I noticed oil has got onto starter. Would that goose the relay.

Terry, you've written relay when you meant solenoid.

You're right Nick. As I recall, the solenoid pulls a lever, which in turn engages the starter gear with the flywheel gear and pushes 2 contacts together, carrying a large current to the starter motor. A relay is a large current switch activated by a smaller current.
