Had it towed to the dealer, don’t want to mess anything up, oil pressure never seen it up 265, and always ran within the normal limits. I’ll update once the stealership tells me.

That's oil temp, we were talking about oil pressure

Towed to the dealer will give updatez

Ya, at first, i thought it was the sound of cavitation as in oil pump cavitation.

On second listen sound like valve train.

easy thing would be check oil pressure first.

zz

Rod bearing is diagnosis, will never buy Nissan again after this haha. I guess corvette is in my future once I swap the engine and sale this thing. 57k miles and blown engine is just terrible. Never drove it hard, maintain as scheduled, just unreal. Bye VQ; hello LS

You did say you are second owner.

You did say an old man owned it before you, so who's to say he didn't run it dry just one time? Did you check his maintenance records?

Yep, I bought from a dealership owner, they specialize in Nissan and Datsun restorations car fax shows maintenance as required so I continued it. Only put 5000 miles on it. Just sucks, loved the car, other than that it’s in immaculate condition inside and out. Just as you would see on showroom floor.

Fortunately I can work on cars have experience with engine swaps and builds. This was the only car I wanted to leave stock and not touch a thing to prevent this exact situation 😂 so can anyone direct me to a thread of ins and outs of engine removal and installation? Anything I should know before buying a used engine? Thanks for input, you guys are awesome!

I still think gallery gasket failure and it caused low oil pressure. You should do like Rusty mentioned and put an oil pressure gauge on it if you want to try to find out what caused the failure

Yeah that's really the only failure point on the engines, either that or it started to burn oil and was unknowingly ran low.

He isn't the first one to have a rod knock on this forum. He's about number 6 since I've been on this forum. Being an '09, I suspect the galley gaskets.

What are the gulley gaskets?

Behind the front engine cover, behind the timing chain. There is 2 gaskets that seal off the oil galley. On the early models, these have been known to leak / blow out. When this happens. You will lose oil pressure, either slowly or all of a sudden. The engine will lose pressure to the crank, rods and everywhere else. The oil pressure sensor doesn't do a very good job. When the light comes on. It's too late.

The noise seems to be on top back of engine, where we traced it. I dropped oil pan and no shavings or metal even with a magnet. Oil was clean as well. Don’t see any visible damage. I’ll have to look into the gallery gaskets
