Lots of oil in spark plug chamber

Post by **Drax** » Wed Sep 27, 2017 3:59 pm

i went to change the spark plugs in the BB4 last night and there is a LOT of oil in all 4 chambers

now i can dry most of this out before removing the spark plugs, but i wont get all of it. it there any biggie if a bit of oil drops onto the top of the pistons, will it just burn off with a bit of smokiness?

I had a similar issue with a B16A i was working on, some muppet had resealed the rocker cover gasket and plug seals with silicone which hadn't worked at all because the gasket was so dried up it had shrunk and completely flattened off, there were literally pools of oil in the plug wells. I used a load of kitchen paper wrapped around a screwdriver to get right in and around the gaps where the socket would meet the plug, pretty sure i got 98% of it out, i didn't notice any smoke afterwards and the engine ran perfect.

In terms of oil getting into the combustion chamber i would have thought a few drops would be fine since some oil mist makes its way in there naturally via the rocker cover breather and through the intake?

A little oil should be alright. I'd bring it up to temperature gradually, then take it for a blast. I'd be more concerned about why there's loads of oil in all four wells...

happened to me before when the plug seals hadn't sealed properly, get most of it out and there shouldn't be problem

Yeah any minor spill of oil into he cylinders will just burn off fine, car will just be a bit more smokey for short period of time
