We bought a 1999 XC V70, had it serviced, compression tested, etc., and a few weeks later it threw a valve.
We have access to a 1998 S70 that we know is good, it's a front wheel drive motor.
Will the two engines interchange? On a site I see they are both listed as B5254T engines, using both VINs. One is AWD and the other is FWD.
Or, could I use the head from the S70 to repair the XC? That would sure be a much easier fix.

While the head will 'swap', there is a VVT on your intake cam with the 1999 that you have to worry about. Both engines are low pressure turbos, correct?
If you swap the entire engine from the 1998, you will also need to play with the computer from the 1998.
I would swap just the heads, but replace all of the valve seals and have the wear on the valve seats checked.

Thanks, Klaus.
So are you saying if we swap the entire 1998 engine, we should also "pick" the computer from that engine?

The 1999 computer expects VVT, coil over plugs, and other goodies to be present.
I assume the 1998 doesn't have them, some of the very late production models might be equipt that way, which would make the swap a cake walk. Both MUST be low pressure turbo.

Thanks Klaus. With your information, I'm guessing that a head swap would be more feasible, as it may not involve the computer to do that...

I am always on the look out for the easy way, and head replacement is that. Just do a good inspection of the valve and valve seats on the donor head. You will probably have to keep the cam covers from the 1999. Do NOT remove the VVT from the front of the cam, too much trouble to get it back on.
Get a new Tbelt, tensioner, etc if you need it. Also a good time to replace the PCV system and clean the intake manifold/throttle body.
BTW, it doesn't matter if it is AWD or FWD.

Thanks again for sharing your expertise, Klaus.
I don't think I mentioned, I purchased the '99 XC with a salvage title from body damage. We had major service done right away, including fuel filter change, cleaning of throttle body, and the air filter was deemed in great shape. The major repair done was replacing all 5 ignition coils. Compression was deemed at that time to be all in the right ranges. After that major service, we put on about 1000 miles, when the valve broke.
Options are, $5300 for a repair to the existing cylinder/valves, with all the required stuff that goes with that.
Or, $1800 for a warranted engine from an internet site, one with about 65K miles on it. Parts and labor to install at shop rate.
Or, the salvaged engine from the '98 FWD S70, installed whole into the '99 AWD XC.
Or, the head taken off the '98 S70 and put on the '99 AWD XC. I think this is the most expedient and possibly the best choice mechanically? It would disturb a lot less.
I'm advocating for the last option.
At this point it's a matter of someone convincing the shop service writer that the turbos are compatible.

Two things; replacing the 5 coils is not MAJOR, each coil costs about $50-60 and takes a 10mm wrench to remove. These must be taken off to replace the spark plugs, that is how easy it is.
The VIN for the 1998 GLT is not correct.
There is an outfit that reconditions heads, new valves, seals, seats, etc. for about $750:
http://www.ramscyl.com/PagesHeads/Volvo%2024%205cyl%20V70.html
I have never used them as they are too expensive for me. A local machine shop can usually do it for much less.
Contact Erievovo.com (there is no "L") for a comparable price for a 1999 XC engine. You will be surprised! Your outfit is just outrageous.

woops, transposition again, geez, where did I leave my mind
correction, Klaus, I've switched them around, sorry
98 S70 GLT VIN YV1Ls5649w1420674
99 V70 XC VIN YV1Lz56d1x2541156
yeah, i'm sure there are lots of ways to do this but i gotta work with what's available to me, yes, it's a shop, i'm sure they are maximizing their profit.
right now I want to try to confirm that the turbos on these two engines are sympatico.
erievovo quotes me $1475 plus $400 shipping so they are the same price range as the other outfit, who quoted me $1800 and free shipping

Both of those engines have the same low pressure turbo. The major difference is that the 1999 has a VVT on one of the cams. The cam cover for the 1999 also has a provision to hold the coil overs, as the 1998 only had a single coil and a distributer cap/rotor.
The best option would be to get the head refurbished with new valves, seats, seals, if a suitable donor head from 1999 cannot be found.
Look around, the 1999 Volvos are quite cheap. Here's one in MN:

yeah they quoted me $5300 for the refurbishing of one cylinder of the existing head, Klaus, for the complete job of taking the head off, sending the cylinder out for refurbish, new head gasket, blahdee blahdee...
that's why we are looking at trying to use the head from the S70
(the S70 is my car which we spent a lot to maintain; it was totalled in front of my house by an impaired driver and is now in a salvage yard a few miles from here)

Your mechanic is nuts. First, the cylinder does not get touched. The head comes off, there are 2 pieces to that (a cam cover on top of the head). Any reputable automotive machine shop can get new valves, how many depends on the condition of the other 19 but usually just the exhaust valves, new valve seats, and valve seals for all 20 ($2 each).
If you went to a Volvo dealer, they would want to replace the entire engine with a reconditioned engine for around $5,500. And that is outrageous!
I have to question how they determined that a valve broke. Just checking compression isn't good enough. They would have to lower a scope into the spark plug hole, and take a picture.
Your car is in the wrong place.

yeah, Klaus, they lowered a camera into the cylinder that was not producing any compression and found a broken valve
i just talked to a second service writer at that shop, the original guy is out sick.
the estimate now is $7800....i didn't bother to ask what all it entails. he said it was $4400 in labor...
i'm not doing any more business there...
i'm now onto looking for a head.
husband wants to know, klaus, if you can say....he located a couple heads but needs to know the casting number of the head. is that the same as the VIN?

No, Volvo engines do not have matching numbers.
Look for a head that has the same VVT as your car. 1999-2000, the 2001 are different all together. There are a lot of them out there, used that is.

We don't know what is a VVT Klaus? Oh I see it is variable valve timing hub.
I am thinking we need an entire engine. At this point it is the most expedient.

Variable Valve Timing. On the passenger side of the engine, one of the cam gears has a cone over the front of it. You will need to remove the timing belt cover to see it. It can be either on the intake or exhaust cam, the latter is closer to the firewall.
This a a Tbelt change video, notice that the VVT is on the intake cam. Have spouse watch the video, it is a good learning show. From the looks of it, this head might work for you also??

Klaus, your comments are so helpful, man. The shop I'm working with contacted Volvo apparently last week, but we are waiting for a reply. Personally I am ready to have the head put on and roll with what comes but I am not with the wrench in my hand.
Apparently there is a question as to the turbo, whether they both match up.
I wonder if anyone here can tell, with the right info?
VIN YV1LZ56D1X2541156 1999 V70 XC (the receiving)
VIN JA3AU26U98U014478 1998 S70 GLT (the donor)
Question being, any information available that the turbo will match when the '98 head is donated to the '99 engine which has blown a valve?
The young man working the service desk at the really cool shop needs some authoritative word to proceed on our collective hunch that it will work. The call was put to Volvo last Wed or Thurs....
