s10lowrider1994 Posted August 10, 2011 Report Share Posted August 10, 2011 Yeah, I can't undo what happened though, I learned my lesson. Think that a volvo dealership has valves in stock for this? I would imagine Volvo stocks them, you'd have much better luck online though as many of the parts sources carry them a lot cheaper than the dealership. Never know though you might get lucky and have no damage, stranger things have happened. The majority of the time you end up with a bunch of bad valves and a little head work, I;ve seen them fly apart and do no damage at all on occasion, just depends where everything stops.

MrWinkey Posted August 10, 2011 Report Share Posted August 10, 2011 I'd advise against putting on the belt and "seeing what happens". If you have any internal damage trying to run the car even for a few seconds is going to do even more damage. You may or may not have bent valves, if you do you might end up destroying a piston as well if you havent already by trying to run the car without checking for any other damage. Sometimes the valves get bent, sometimes they dont, more often than not though they do receive damage. The safest way to go about it is to pull the head and see what you have and go from there. If nothing is damaged you're out a few bucks for a head gasket, with the probability of something being broken or bent though its really the correct way t go about it. You could put the belt on and cross your fingers but why chance it, especially if you have a mechanic at your disposal. Personally If I receive anything with a broken timing belt, the head comes off, no questions asked. Trying to cut corners and save time is just asking for trouble. sigh Link to comment Share on other sites More sharing options...

Slaywood Posted August 11, 2011 Author Report Share Posted August 11, 2011 reply from mechanic brother: we tore into it last nightt: we pulled the cams and belt etc., so the valves would all be closed. then measured the height of all the lifters to see if any were hanging open (shorter than any others) and all measured good. then we took the hose from a compression tester with the core removed and blew air into all the cylinders. all were tight with almost zero leakage except for #4 which had a very slight hiss into the intake. i'm on the fence about that cylinder, as it could be a bit of carbon etc. holding the intake open?. i would have thought if it hit they would have catastrophically bent, not just barely tweaked enough to seep air. i reeeeeally don't want to pull the head if we can help it, but i want to do it once and do it right! we're going to locate a borescope to check for witness marks on the piston top and if there was contact the head is coming off. otherwise he's the luckiest person on the planet! and fwiw, i had every intention of changing the belt this week, swear to god! he asked me about doing it last week but i was on vacation, i can't believe it couldn't hold on for a couple more days! even if we hafta replace the 2 valves, we'll be out of it for less than the stealer would have charged to do the belt in the first place so thats a win, and most of the seals and gaskets were pretty cooked from all the heat so it will be sealed up nicely thanks for all your input, it was helpful, i just didnt like the idea of cranking the engine with so much stuff open and unplugged to do a compression test so i substituted air- Link to comment Share on other sites More sharing options...
Slaywood Posted August 11, 2011 Author Report Share Posted August 11, 2011 boooooooo! ONE valve hit... #4 intake, head is coming off with much cursing and fist-shaking hahaha. couple stupid questions: has anyone here physically pulled a head on one of these? can i leave the exhaust manifold attached and just disconnect it from the turbo or do i have to soap up my arm and slide it in there to undo the manifold from the head with it in the car? also, i have never done a timing belt on anything with vvt, is it possible to put the belt on one tooth off due to the slack in the cam sprockets or do i just line up the marks and let oil pressure do the rest? thanks for any info its gonna be a long day!on the plus side, this is a fun bonding experience and he is learning a lot... now he can picture what all the widgets are doing in there while it's running (AND why 135k is waaaaaay too long to run a timing belt)!

PyROTech Posted August 11, 2011 Report Share Posted August 11, 2011 i had the same thing happen to me, but much worse. Since then i have been always extremely careful. good luck with the repairs. Link to comment Share on other sites More sharing options...
NEU Posted August 11, 2011 Report Share Posted August 11, 2011 I had been putting off the timing belt till this coming weekend. Wanted to ad, 135k is far beyond what anyone should put on a timing belt. (AND why 135k is waaaaaay too long to run a timing belt)! You were really living on borrowed time, 30K worth! The RN motors timing belts are due at 105K. So if you do 15K a year it was due 2 years ago.... :ph34r: Link to comment Share on other sites More sharing options...
bum2kev Posted August 11, 2011 Report Share Posted August 11, 2011 good to hear that compression came back good..let hope its some carbon. get a borescope to check it out. Link to comment Share on other sites More sharing options...

Looks like I was correct about the valves, damn what a shame! a broken belt is difference then being off timing, who would imagine that! way to be a dink though, thankfully your good at that!

MrWinkey Posted August 12, 2011 Report Share Posted August 12, 2011 How endearing! Looks like I was correct about the valves, I never stated you were incorrect ...I only stated give it chance before you pull the head. I apologize that my 20+yrs of professional experience made me type that. It's all good Link to comment Share on other sites More sharing options...

I apologize that my 20+yrs of professional experience made me type that. It's all good I was just messing with you for the one word comment. No issue, just anoyying playing 12 year old with someone that busts out a$& clown squirrels haha Anyway, back on topic. To the OP, read the VADIS manual on how to set the VVT since you will have to remove it to swap the seal. The bolt can be a major pain so i would recommend doing it out of the car with an impact gun. Also get the valve stem seals from volvo and have the machine shop do it. Much better then some random over priced seal they will use. Link to comment Share on other sites More sharing options...
