Title: Oil in the plug wells
Post by: Brian T on 14 July 2008, 16:46:36
Over the weekend some of you were good enough to help me diagnose the possible cause of Oil in the plug wells. What started out as a 10 minute job to change 4 plugs has now turned into a slightly longer problem to resolve. But my question is.....
How do I get the oil out of the wells. If I take the plugs out surely it's going to go into the pots. As far as I can tell I cant remove the cam cover without removing the plugs. So whats a boy to do?

Also....there's always an also!
Would blocked breathers affect fuel consumption?

get pack of kitchen rolls.

Tear 1 bit off.

Roll it into a thin cigar type shape, then push it down... maybe use a screwdriver to push it right down to get the last bits.

I have always intended to go into the pharmacy and ask for a pack of syringes ::) (for motoring diy purposes of course!)

OK now I'm confused...again!
To change the Cam gasket I need to undo the 10 torx bolts either side of the ecotech strip correct?

When I lift that off are you saying that the plugs stay where they are?
Sorry to sound dumb but this will be my first gasket change :-[

If you do take the plugs out, I don't think the oil will do any harm at all if allowed to fall into the pots. Will soon burn off, even if it is held in the pots until you start up again.

Too much oil can have very bad effects .. it may foul the plugs and prevent ignition (neat fuel then reaches the cats)..... and can also "coat" the precious metals in the cats with oil  .... both these can damage (if not destroy) them .. an expensive risk for a bit of time with some paper towel !!!

I think I agree Shyboy, but if the oil is excessive the initial mis-firing start up, with a very oilly mixture, could allow too much fuel to remain unburnt and cause damage to the cats? :-/ :-/ :-/

Just a thought, but could be totally wrong! ;D :y

The amount of oil held in the plug wells wouldn't be that great though would it? I'd be very surprised if it interfered with ignition on start-up, but I suppose a few minutes spent soaking it up would be a good insurance.

If you let too much oil into the combustion chamber it could cause a problem.

Oil is not compressible and at the top of the compression stroke the volume of the combustion chamber is pretty small. If the volume of the oil exceeds the volume of the combustion chamber the engine will hydrolock. At best it won't turn over. At worst it could cause serious damage as the piston is forced up into an immovable mass of oil.

I would clean up as much as possible before removing the plugs. A little oil will do no harm and will just burn off when the engine is started.

As ever useful advice with lots of various opinions all of which I think point to the same thing.....basically get the oil out first.

Sage advice guys and gals, I will spend the time cleaning it out as I need to put new plugs in anyway and I'd rather not shower the neighbours with clouds of blue smoke!

Yep - I think that is the best bet, mop as much of it out as possible first.

Take it steady with the cam seal and make sure to clean the breathers  and not over torque the cover bolts on reassembly.

I've just spent £30 on a Torque wrench that goes down that low my old one starts at 25nm!
