Time to do another valve adjustment(every 160k) and spark plug change on K20 with 320k+ km.
PP 0W20(winter), 5W30(summer) and sometimes a mix of the two(left over oil from unused jugs) + Fram Ultra(every other oil change)
MM usually indicates 10% oil life left around 10-12k km of driving.
Compared to 160k pics, no obvious difference under valve cover.
Spark plugs remain at 0.040 gap, will put new Denso TT spark plug in.
2 questions:
1. I did not replace the spark plug tube seals last time. From these pics, seems like 2 have a little oil leak?
2. I stupidly applied a bit of anti-seize last time when installing new spark plugs. It did make removal a bit rougher. Is there an easy way to clean up the threads a bit?
