my opel astra started doing the exact same thing after I did an oil change. Oil light comes on while engines running. The weird thing is, it started doing it after the oil change, same day. I had the correct type of oil too. Still havnt figured out what it is yet

[vbevan]

You used the right weight as well as correct quality (mineral/fully synthetic/whatever you had in before)?

You changed the oil filter at the same time?

[vbevan]

After some advice by others I think it's lifters. It stops as you rev as oil pressure increases...oh well, probably time for an oil change.

Imma run some cleaner through mine and change oil and hope it fixes it mine has about 30 psi oil pressure and ticks then it gets warm stops ticking and drops oil pressure to about 15 psi idk ill guess I will find out

Lifter Issue, these things and the Vh41s were chronic for it

sounds like a lifter issue

[m4a1fox]

Oh man, I know this vid is old, but I bet it was rod knock--sounds just like when my S13s KA went out--I know for sure my z32 has lifter tick, and this isn't what it sounds like!

i would say exhaust lk and a rod knock 99 percent sure run thick oil in it and fx the leak if you care enough about the noise

[TheJordanpost]

Oil pump is really bad, didn't make the noise with the old thick oil, now with new clean oil at idle both noises bearing and lifter are caused by bad oil pump. don't drive fix the pump asap.

ok sir OP .. the first noise it lifter for sure..but after u done reving .. it also have a knock knock knock .. and that not good at all..

[SuperStevenallan]

Two things I think. Just a loose lifter. When you give gas it stops so it could be a weak oil pump when give gas pump works more to get the oil on top of lifters. Somthing to check. Just giving a little advice just trying helpout. I could use a little myself I'm going to change the headgaskets in my audi90 1993 at this moment. That's why I was searching on YouTube I saw your video so I checked it out. I'll take any advice Highly apriciated thanks!!!!
