Bent Valves - slipped timing belt

3 posts in this topic

Hi,

I have a 2004 V70R with about 145k miles.  I did the timing belt shortly after I purchased the car 4 years ago at about 81k miles.  On our way home from visiting family over the 4th of July Holiday the car started running erratically and then refused to start at a rest area off the highway.  I had the car towed to a local repair place and we diagnosed that the timing belt had slipped due to a locked-up idler pulley and I authorized replacing the timing belt, the water pump, the idler pulley and the cam o-rings, etc., hoping to get back on the road.

The repair place called me and said that the car is back together and refuses to start which to me and everyone else means bent valves in the head.  I can't afford to get all the work done at once and was thinking about getting the car towed back to me - it's about 70 miles away - and taking the head off myself and sending it to a local machine shop for repair.

I have a few concerns mostly regarding the pistons and if there's any damage to those but I probably won't know much until I get it apart.

Questions:

1) Where can I find a service manual for the car?  There seems to be a few on-line pdf files or things on ebay - are those legit?  Is there a preferred source?  I did a search here on the forum but didn't find anything.

2) In terms of buying additional parts - like head gaskets, and other items what's a good/reputable source? 

3) I've done this type of work before but not on a car this complicated/new.  Are there any "gotchas" I should be aware of; especially in the turbo area?  Or can I just remove the head, send it to the machine shop and put it back together - all things being equal?

4) Does anyone have any experiences to share with this type of thing?

Thanks,

conorb

Sorry to hear the bad news.

As these engines are interference engines, most likely the valves are cactus.

Unfortunately, no detailed service manuals for the R.

UK publisher Haynes publish a V70 manual - but not specifically for the R variants.

I'd suggest obtain a copy of VIDA, legally through Volvo Cars bookstore, or though other vendors on various eCommerce marketplaces.

Depending where you are, FCP or ipd are good sources for parts.

Thanks for the pointers.  I've been able to get the car home and I'm hoping to do some preliminary inspection in the near future.  I live in the PDX are so ipd is probably a solid resource for me to check out.

Thanks again.
