The other day was driving my car and got up to 140~km/hr and suddenly the car stalls, I started it back up again and slowed right now and the car won't stay idling and the oil pressure light kept flashing, I was about 2 blocks away from my house and as I was driving it the car lost all power and by time I got home I couldn't even get it up the driveway it had no power.

So now I have the car up on jack stands I did a compression test cylinder 1 had 140 cylinder 2 had 140 cylinder 3 had 125 and cylinder 4 had 125, I did some research and what happened was the timing belt skipped a tooth I took it all apart bought a hanes manual and timed the car properly, and still the same noise... I did a compression test right after and all cylinders jumped up 10... *if there was a bent valve wouldn't that mean their would be no compression, or it would slowly drop??* I took off the valve cover and adjusted the valves most of them I had to back them off, but some I did have to tighten so now their all within stock specifications. I took out the lifters and replaced them with new ones still no change in the sound... It is definitely a top end knock/tick sounds like right underneath the valve cover on the driver side.

Here is a video I found off youtube that sounds identical to my knock I understand video to real life is different but this is really close if not the same issue. that isn't my car or me in the video.

I'm lost now on what to do, or what the issue could be I've done lots of research and nothing has worked yet... If the head or valves are ****ed I have a spare head to put on, and spare block, worst case scenario. Any help/suggestions/or ideas would be greatly appreciated thanks in advance.

Needs an engine? Flashing oil light screams of too much clearance in the bearings (spun a bearing, trashed a bearing, etc.).

Pull the oil filter off and cut it open (don't use a saw), look for metal in the element (trashed a bearing)...If you find metal then pull the oil pan and check bearing damage. (Note, only the smallest pieces may get past the screen on the oil pickup tube and into the oil filter. You might find a lot more metal in the pan when you get it off.)


The engine noise in the video is caused by wiped rod bearing(s). The actual noise is probably coming from a piston contacting the bottom of the cylinder head.
