My morning disaster - how done am I?

A 99 engine won't really work. Lots of parts are completely different between the two.

Valves are not hard to replace If it turns out you bent some valves, I'd reccomend that you rebuild the head yourself, replacing whatever valves need to be replaced in the proceess. Its possible that the damage is more extensive than just bent valves, not not all that common. Sometimes the pistons can get badly damaged and or the valve heads can break off and have a little cylinder party. Again though, worst case scenario and more often than not, you can inspect all the valves and replace as needed.

So, do I NEED to be looking for ONLY '95 to '98 model engines? Or something like that? Can somebody tell me please? I seriously can't use the '99? That really sucks...!!
Thanks

I had exactly the same thing happen on my 98 V70 5 speed. The mechanical tensioner crapped out and the belt walked off the cogs through the plastic cover. I ended up having the head redone, 4 bent valves and replaced everything connected to the TB. All good now, cost a bit but the car only has 130k kms on it and seven seats. Stick with the original bottom end if still in good shape I reckon. The cost to change out with another engine with no history was about the same as doing the head up. Cheers.

If you buy the car ran on Diesel - I'd also replace the O2 sensor. Low sulphur diesel has some silicone in it; which kills the sensor off fairly quick.

This actually happened to an entire country one day:

Many cars died that time, but the fix was easy. New plugs, oil change, new O2 sensor, drain the diesel, change the fuel filter for completeness and you're good to go!

If you can get that V70r for cheap, it's worth a thought!

Try Vance Hanes Auto Parts Can-NS(Upper-Brookside) as they might have your engine.

The first question to think about is .. do you have the time an ability to change this engine... which means you will have to also pay for the transmission too from a wrecker if your going to change the whole unit. Make sure you inspect the main seal before you put it in to ensure your not going to need to remove it again because of oil leaks.

Changing the cylinder head might be easier, but how much do you feel the car is worth to you? There is certainly a lot of good advice and instructions found here to help you out if you decide to tackle it.

If you feel that you want to go ahead and keep the price down then rebuild or find another engine which you can take the top-end off. I usually look for cars with less than 200,000 kilometers in good running condition. The most economical option might be finding an 850 which has the similar engine. ( The 98 s70 is essentially a 850 with a nose and butt job)

The hard part is finding any Volvo's in the Maritimes, there are very few if any listed in Craigslist. Maybe Montreal or New England is the place to go?

Here's a few pics. Im not sure how to inspect, theres a 12mm that holds on the cover, that right? Gone to check it out. Looks like from pic 5 the belt is not on the cam gear, so do I have to worry about a tool that will lock them together... to late anyway isn't it?

Belt is off, timing is off but not incredibly. Ball bearings suggest one of the rollers failed.

I have been through this too, I know the sinking feeling. Presumably there are bent valves but the only way to know for sure is to put it back together and try to run it. See You have 2 options: pull the head and have it reman'ed or put in a reman you pick up somewhere else, or swap the engine. I've recently done both, here are my thoughts.

The engine swap takes longer but is much less technical. You can't really screw up an engine swap, you just take stuff out then put it back in. Compared to the head swap you need more space in the garage and special tools (engine hoist, engine stand). A good thing is you can freshen up all of the seals on the engine (there is a great write-up here at MVS), and end up with a setup that will run a long, long, time. A bad thing is you can never be really sure about the condition of someone else's used engine.

Pulling the head see the first response from JDS60R. Except don't expect it to take 2 days, if you are a weekend mechanic this will probably take 3 or 4 weekends by either route. Pulling the head is much more technical, you have to do things right and more carefully, but about the same amount of work (and time) as the engine swap. A good thing is the valve stem seals tend to go out on these engines anyway, so you can freshen those up when the head is rebuilt. Use only the Volvo branded seals.

Thanks for the moral support and advice. I really don't know what I'm going/should do yet. About any of this.

Here's a vid of what I guess went wrong (and I think what people told me went wrong), tensioner pulley? Mustve blown up and shot those lil ball bearings everywhere.

Wow! Hard luck. I hope you haven't bent anything but it looks like you are in for an interesting weekend or two.

That video is the reason I replace all the rolling parts at every timing belt change-no matter how 'good' they feel.
