E30 (1982 - 1993)
God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

Mein Auto:
Oil leak in spark plugs

So hoping someone can shed light on questions i have regarding my 1989 325i 5spd. Iv done a minor tune up on the car, spark plugs, cap rotor, belts etc.. When i first got the car a year ago i changed the spark plugs and they were covered in oil and a few months after putting the new plugs in they also are drenched in oil when i pull them out. Iv done 2 valve adjustments as well and the car still sounds extremely loud. Idk if i need another head or can mine be saved. Any feed back would help, thanks.

Do you mean the 'inside the engine bit' or the 'outside the engine bit'? If you are oil soaked on the out side - Rocker Cover gasket. Oil soaked on the inside - oil burning. Maybe a head rebuild (new valve guides etc) will fix. This does not sound like the head is cracked, so you should be able to get it reconditioned if required.

Probably valve guides or seals as BMWFF mentioned.

Are they all covered in oil?

How much oil is she burning per 1000 miles? If it's a lot it could be bad oil rings, too.

That sounds like the valve cover gasket is leaking. The oil gets on as you screw them in. If you were burning oil, there would be burnt oil build up on the prong and possibly fouling the gap to the point it wouldn't fire.

Not what I asked, but if you are driving the usual 1K / month than a half a quart is a lot of consumption, which suggest bad oil rings. Unless you have oil leaking from seals and such. Is the lower half of the outside of your engine covered in oil? Is the subframe (cross member-type thing) covered in oil? Is there a lot of oil dripping from the engine area onto the ground?

I dont go with the R/cover ol'grouch. No oil on the outside. I would suggest head recondition, bore check and maybe new piston rings.

After the OPmentioned further details, it sounds like an internally weeping head gasket. I think it will get progressively worse with more miles.
