A little spark plug inquiry

[Mortification]

Wey I just removed some of my plugs and wanted your guys opinions. Also confused about the liquid substance I found on them. On to the pics...

Also just noticed part is #BPR7ES... which doesn't trace to a 325 at all ?

[e30davie]

is that lyquid oil or fuel?

If that pool of liquid in your spark plug hold oil? if so your tappet cover gasket might be leakin.

Hard to tell from those photos, but they do look a bit sooted up. does it run rich? hows your fuel economy?

Do you know when they were last changed? If they are fairly new, give them a clean up and re-gap them. If you dont know just throw some new ones in.

[UlrichFennec]

You look like you're running rich. Was the liquid on the plugs oily or was it fuel?

BPR7ES are 2 heat ranges cooler than stock IIRC. There's not neccesarily anything wrong with them, but I would switch to a BPR5ES for a stock engine.

Funny thing is when you search for these plugs, they are also used in lawn mowers. lol

[YosemiteSam]

I hope I'm wrong, but from those pictures that fluid looks kinda coolant-ey to me. If that's the case OP, that would not be a good sign.

[flyboyx]

i think it looks like oil

[nando]

yeah if it was enough coolant to coat the plug, I think you would know by the huge clouds of smoke coming out of the engine.

[Mortification]

Well if it was coolant where would it be coming from? I'm not sure but it seems all the plugs have it. Maybe wd40? I didn't do this and I just got car not too long ago. Also car had a previous turbo setup and had a turbo chip... hence the plugs I'm guessing and the running rich part. I just switched the chip out. From my understanding these cars don't have spark plug seals like Hondas do. So it's definitely not coolant. The fluid was in too part of plug. Not inside... if it was coolant my guess would be that it'd be on then plug itself from combustion chamber? Correct me if I'm wrong.

Also ... FYI head gasket was just done by previous owner. Or so I was told but the head looks clean as hell to me so I believe it. Also the engine is a 2.7 with a is head from what I've been researching.

he probably meant to go one heat range hotter - but NGK numbers work backwards. lower number is hotter, higher number is colder.

Well I have a old thread about me trying to find out what my car had. Apparently car was running a turbo setup. Hence the colder plug. Gonna switch back to stock today

bpr7es is a popular turbo plug. PO probably just never went back to stock when selling the car.

Also can anyone tell me anything about that pulse sensor that goes on the spark plug wire? I'm running a I/is head on a 2.7 block apparently and can't find details as to what that wire does or where it connects to. Any insight would be greatly appreciated. I'm completely new to this e30 stuff. Thanks

[Mortification]

Heck I don't even have that sensor on any wire
