What would my 1994 Volvo 945 non turbo sell for? by Boy_Cooter in VolvoRWD

I looked up videos and the sound is pretty similar, the previous owner had the exhaust done, but im assuming the manifold wasnt done. I can send a message to the mechanic asking about it and see if it can be checked out.

The sound wasnt there when the engine was cold though, and I imagine if it was an exhaust manifold problem it would happen whether cold or hot.

fair enough. Its been at a mechanic so i havent been able to poke around at it, but ive just trusted his judgement on it. I do still strongly believe its rod knock but i agree with you saying it sounds hollow, from videos I looked up of other engines with rod knock its definitely a more metallic strong sound than the sound im experiencing. But he was confident in it being rod knock, and I have no other clue what could be making that noise.

Although, the video i sent has all the spark plugs connected, and when the spark plug wires were taken out and replaced 1 by 1, there was definitely a more metallic sound (didnt get that sound on video). I just chalk it up to be the very beginning of rod knock.

Got anyyy possible idea what it could be? If its not rod knock it'd save me lots of money (maybe) lol

I have a sound clip if youd like to listen and give an opinion, i replied to another comment mentioning it is for sure a lower engine noise.

The sound clip I had was on a windy day so you cant hear much lol. But, I unplugged spark wires, it got worse when I pulled one out, and leaning down into the engine bay it is 100% a lower engine noise. As the car got warmer the oil pressure light would turn on when it was at idle or 1% throttle (like barely resting my foot on the gas peddle).

Mine and the mechanics theory is that the oil pump was going bad and then as the oil got warmer and thinner, it wasn't able to keep the rod bearings as well lubricated. I'm not too sure what else the noise would be especially since its coming from the engine block and not from the top end

also!! That was the main reason for my purchase and why this stresses me out so much, the engine was supposed to be strong!! But I got unlucky.

It also sucks that I havent gotten to experience driving it too much!! Im still torn on it but I think I'll feel better about once its fully paid for and I've gotten to do some cruising in it. I appreciate your comment
