What Happens When A Timing Belt Breaks? ~ FSI Timing Failure

What actually happens when a timing belt breaks? What does a broken timing belt sound like? What is timing belt noise? How much does it cost if a timing belt breaks? These are all timing belt questions I get all the time. Well today we have a 2007 GLI(same as a GTI) FSI that the owner said it had a broken timing belt. We are going to walk through some quick checks you can do to see if your VW has a broken belt, or a broken chain. This engine has both!

Yes yes yes! Finally some more BPY content! I'm so glad you mentioned checking the oil pickup. It's not sufficient to fix the valves w/o finding out WHY it done broke in the first place. Kind of obvious in this case but still -- it's good to be as thorough as you are. Did you know that sometimes more than one thing can be bad? lol. I hope we get to see you do a full valve job since I'm not aware of any valve job videos on all of KZbin covering the BPY let alone ANY VW engine.

[@nigel-Rollercam-channel]

I have had 2 vehicles with interference engines survive a T-belt snapping. So much work for what should have been a little bit maintenance. I thought I preferred timing chains, but now I find that the timing belt change interval helps insure that all the other items that need attention are taken care of. Timing chains just give people the false impression that everything is ok, yet the water pump is seeping and the power steering lines are leaking amongst all the service that has been avoided. Plus cost and accessibility sucks on engines with timing chains, such as B6/7 S4 V8's. Thank you for all your detailed videos!

[@commonsenseisdeadin2024]

Those 2 vehicles happen to be on BPY engines? My timing belt snapped and I see no witness marks on pistons or what I can see off the valves with a dual lens bore scope. I'm going to toss on a timing belt and see! Mines a 06 A4 and the pistons have some relief cuts (which I'm not seeing on others however there's not many others I've seen 😂)

[@blueridgerennsport]

BTW, I have experienced several instances of the dreaded "no compression" sound when re-starting engines (that had been recently started, ran briefly but not fully warmed up, then shut down again) in cold but very humid conditions. It's apparently caused by carbon deposits on the intake valves swelling and preventing them from closing fully, but not enough to make contact with the pistons. When things get cold again for a while or fully warm up, the engine usually takes some time cranking, but it will start. It's a strange phenomenon and doesn't happen very often, but it's quite a relief to customers who thought they were looking at a huge bill.

[@joseargueta4373]

Two things I took from this video. FSI engines are suprisingly similar to 827 DOHC engines from the 80s. And that little secondary timing belt tensioner on the right at 0:25 is a genius invention that stops the timing belt flopping around like it does on my mk2. And yes I tightened it properly.

[@WreckedRevival]

Oof yeah after doing the forged build on the mk5 GTI I had which previously suffered from balance shaft failure, I decided to part ways with it. Mostly because of the dual timing (belt & chain) combo + oil pump/balance shaft setup, overall just too many points of failure in the timing system for my liking.

[@KeithSWD]

My 2005 Chrysler neon cranked exactly like this when it stalled my to town, weeks ago. Weeks prior, it had rough or rattling idling and unusual misfiring at times.

[@helifynoe9930]

Fortunately on my brothers old Volkswagen Jetta, even if the timing belt is screwed, the valves can NOT end up being damaged on that specific engine. In his case the timing belt had slipped due it partially falling apart to the point in which the engine would not run. Anyhow, on the coldest day in years, we still managed to fix the problem via installing a new belt, and set everything to being positioned as it should be, based upon dot position markers, etc. Of course as we tensioned the belt, this knocked off the proper dot positioning a bit, so we offset the position an equal amount in the opposite direction such that once the belt tension was set, everything was at as it was supposed to be. I guess someone else did not take this into account in the past, because we now had a ton more power than ever before.

[@magellanmax]

I'd love to see this particular repair job. Film it if the customer opts for the fix. I had a B5 A4 that had the belt snap but I junked it since it had over 460K miles on it.

Anyway, they are saying that my car is too old and a wedge from the crankshaft broke while the mechanic was testing the engine after replacing the timing belt. What do you think?

Hi HumbleMechanic... I done myself and gotten a 1996 Audi A6 with the ACK engine (30v V6) and I'm about to do the timing belt (amongst other "while you are in there...."). I've gotten one tool for locking the camshafts, but won't I be needing several tools ? How about locking the crankshaft?

[@jordangroves5068]

Charles! I have a 2007 GLI. I am dealing with quite a few oil leaks, the obvious vacuum pump seal leak, but also apparently there's a leak somewhere at the timing belt and the manifold cover as well. Taking it in next week for repairs. My mechanic told me to get it fixed soon because good chance there is oil on the belt and its wearing away. I'm hoping this isn't too expensive of a repair. With the timing belt leak, in your experience, where do you think it is leaking? I am going to try and tackle to vacuum pump leak myself (thanks to your help) but I'm worried about this timing belt leak. Thank you, I appreciate any advice you can give

[@krazykyfan]

My wife's Beetle Turbo (2013.5 model) had a timing chain tensioner that failed at 44k miles. It would barely turn over and had little to no power. Ran the codes and it came back as a "camshaft positioning sensor" fault. Took it to our local VW shop and thank God it didn't have bent valves or any damage from the problem. Warranty covered 70% of the repair. Turns out there was a recall on the tensioner. Shop had it for a week lol.

[@HumbleMechanic]

It must have been out of warranty by time? Luckily the chain didn't break, it sounds like the tensioner may have been maxed out. Glad you didn't have to pay that whole bill.

[@krazykyfan]

@@HumbleMechanic yeah as you are probably familiar the warranty pays out at different percentages based on the length of time elapsed since the recall. The tensioner hadn't completely failed but was almost there. Apparently it was a problem with the early production third gen EA888 2.0 TSI motors. Hers was one of the first models made with that motor.

[@rxpx69]

Just attempted the chain last weekend along the way I broke the coolant flange nipple, broke a VVT plastic seal in the VVT housing just by touching it and broke a vacuum hose, but got the VVT adjuster bolt out without it stripping so that's a win!

[@HumbleMechanic]

Some of that stuff you can’t even look at.

[@lukew2194]

So, now you need a new VVT adjustment unit. How hard was that bolt to take out? Did you use the proper bit?

[@rxpx69]

@@lukew2194 Luckily I've found the 3 plastic O rings on their own for the VVT housing side of things, but my VVT adjuster does have grooves inside of it so i'll have to see if goes back together without throwing codes, a few people on forums have said they've not had issues from the wear in the grooves. Advice I would use for next time MARK THE CAMS BEFORE UNDOING THE CAM BOLT and do not use a cheap Chinese cam locking tool, on my cheap version there is a small bolt holding on each of the two legs to the top of the locking tool, the legs snapped off with ease when trying to undo the the big cam bolt, the camshafts just pushed against the legs and pushed them out of the way, I was able to reinstall two stainless steel M5x20 bolts to reconnect the cam locking tools legs back on which allowed me to get the cam bolt undone. Also bought a cheap ebay T40080 socket which didn't even fit the cam bolt so ended up using a T40080 made by Laser and worked well, I'd recommend undoing the cam bolt with one arm and using your other arm to grip the VVT adjust while pushing the T40080 tool into the bolt so it doesn't slip to the side.

I'm in Canada and despite what my dealership says 5 months or 8000KM albit this is a GDI turbo engine and set my onboard service interval to 4 months or 4000KM and that's using Amsoil full synthetic oil.. sometimes I use 5w30 Sig series and when money is tight I use the same but it's the OEM branded also using a catch can.

Hi, I have a 2007 VW GTI. I changed the timing belt at 120k but am wondering about the chain???

[@tjayrichards4175]

This happened to me with my Hyundai Sonata, is it better to get a new engine?

I had a piston dissappear on my 07 GolfV Gt Sport 1.4 Tsi. Weird!!!

My 2005 Audi 2.0T made that exact same sound when the timing chain broke at 230K miles (after breakdown it appears the tensioner failed). Ironically I was going to replace to chain and tensioner on the weekend (this happened on a Tues). Rebuild was not too difficult. Not as much internal damage as I expected.

Hi. My tensioner failed and the chain broke, I am skeptical about pulling the top because I think changing the chain and tensioner will work. What was your experience, did the valves bend? Did you need to pull the top?

@@charlesikechukwu5081 I pulled the head because I was certain valves were bent but all were perfect even though it’s an inference engine. My car is a manual and I instinctively immediately slammed the clutch pedal to the floor. I have no clue if this saved the valves or not. I did replace the head anyway because the cam guides were seriously worn after 250,000 miles; almost the depth of a human hair in some spots. If I were you I would pull the head just for inspection and cleaning (great opportunity to clean carbon buildup). If all is good it will only cost you a head gasket and 10 TTY head bolts. A small cost for peace of mind. Good luck with you project and let us know how it turns out.

Great video Charles . I guess the million dollar question is when do you walk away from a repair , junk the vehicle and buy something else . Do find yourself advising customers on what to do financially ? I have a hard time spending thousands on a repair when the car is on borrowed time .. Your thoughts please ?
