Inside a 300,000 Mile Volvo Engine - Teardown, Disassembly, and Inspection

► Ever wonder what the inside of a 300k mile engine looks like? On this special bonus episode of the 850 project, Cory and Jacob tear down the original 850 N Whiteblock engine to see exactly what age and a ton of miles do to the inside of an engine. From the cylinder head to the oil pan with piston rings, cylinder walls, rod bearings, and crankshaft in between, we find out if this engine was on its last legs, or had another 100k miles under its belt.

This kind of old engine disassembly videos are always so interesting! I want more of them.

Explains a lot, I put well over 300K on this same 5 cylinder and was amazed how well it still ran, although it was needing some oil added at that point. Incredible engines.

At my previous job there was someone with a volo 240, and he had 850000 km with the original engine . The man said that he changed the oil once a year, regardless of the km he had driven. There was even a year that the car had driven 88000 km with the same oil. An oil change once a year regardless of the km was sufficient, he said, provided you use good quality oil. He did check the oil level every month, and when necessary he topped up a little .

Great video guys. So nice to hear two American professionals talk knowledgeably and respectfully about non-American cars!! Gotta give credit where it's due and Volvo do it right. Good job. 👍🇬🇧

Appears to have the original water pump.

With the condition of the engine, I’d wager that it was owned by someone that did a lot of long highway commutes. They’d be getting it serviced more often, and putting the engine through less heat cycles

Had 850 T5 and 850 GLT wagon, really amazing cars all around, so incredibly reliable, with proper maintenance these volvos will practically last 500k. Amazing machine, really miss it.

very well kept. frequent servicing in shorter intervals is the trick for a engine long life.
I have just bought a Volvo S80 MK1 with 718K miles, nearly 1.150 million kilometres, which I am going to repair and carry on driving. its on its second engine though, but it has done nearly 370k since it was fitted in the car.

I went to a Volvo dealer with a 2006 S60 with around 237, 000 km on it and they wanted me to replace the engine for $17k. I said 'nope' and left. I took it in to begin with cause the exhaust was blowing white smoke and had a burning smell in the cabin. Found out later that the only problem was low oil in the engine. No problems since i topped up with a quart.

I sold Volvo at my dealership for 20 years. Those 5 cylinder aluminum engines are the best of the best. They have great power and are reliable. I highly recommend one. Yes, you have a few oil leaks and if you don't keep your oil changed, you will have messes. Go Volvo!

The biggest thing I took from this video is BMW need to talk to Volvo about good rod bearings 😂😂

[josechimal]

Those 850's are tanks, I have two 850's and they are great machines.

[yearssober]

I have a 1992 740 Volvo with almost 500K miles all original. Valve cover has never been removed. Nothing but regular oil changes. If you’re in Florida I’d gladly let you tear it down and inspect it.

Sent my 99 V70 to the scrapper with 330K, no reverse for a year prior, the son had bounced it off a few trees, but it ran good, just found an 01 V70T5 with 115K, super clean for $3000 USD. Volvo for life.

[ryanspeck]

I pulled apart my friend's 99 V70 engine apart after it burnt a valve and it was the same story as this. Could not believe that there was basically no wear on anything. Lapped in a couple new exhaust valves on that cylinder and put it back together. Runs good.

[medic-chan]

YouTube recommended this video and having never seen your stuff I thought, "Wow, what a beautiful volvo engine for 300k miles, I can't wait to see how they restore it!"

All the way until right before the end of the video, haha.

[davidellis]

Considering the mileage that engine was in great condition and would probably gone on for another 100, 000. The wear on the Crank Journals was probably unmeasurable from new if the shells are anything to go by and the cylinder bores still had honing marks on them. That engine could easily be rebuilt by fitting new Piston Rings and Crank bearings along with a decoke and the valves relapped and reassembled, it would probably go on to do another 300, 000 miles.

Not at all surprising. Around 2008, my dad's car got totaled and he began looking for a replacement he could pay cash for. We found a 1994 740 at an independent dealer. It showed 140, 000 miles or so. We took it for a ride. The blower motor loudly spat debris in our faces, the transmission was firm but strong, and the engine loudly clattered it's way up to speed. Dad felt it may have a had a few more miles so he checked it's history. Turns out in 1998, it went in for service at the dealer and the reported mileage was around 250, 000. The thing had probably rolled over. Impressive!
