oil in the 1st spark plug

[r0nin]

been reading online and it looks like the o-ring probably gave out.

doesnt suprise me since the engine probably hasnt had maitenance since manufactured in 92

was wondering if i need to take it to the shop, or if it would be cool to do myself?

and if all it would be is the o-rings....

That's a DIY job. Pull off the valve cover and replace all four spark plug tube seals.
