EA888/1 2.0t TSI Seized Balance Shaft removal & Checking for bent valves

[@pvfeB7Ax]

Yep, happened to me TWICE on my 14 GTI. The second time it happened I got rid of it. Now cruising in a 16' Audi A3! No one's had any issues with the balance shafts on the gen 3 engines yet! 🤞

[@Weissworx]

Nor have we. The Gen 3 went to a needle roller bearing style balance shaft, which seems to get better flow.

Awesome video. Where did you get the service manual book from ? All i can find are downloads from Erwin USA. Thanks !

[@Weissworx]

Shoot us an email. I can send you the pdf files we have.

[@trojangpete8]

excellent! so why does vw say that if you remove the bolt on the sprocket above the intake balance shaft, that you now have to replace that sprocket, even if you just loosen it?

[@Weissworx]

Which bolt above the intake shaft?

[@musondachansa8035]

Thank you so much you're a life saver, keep it with your good work

[@scoobdoo4233]

That spur gear on inlet balance shaft did you replace it as recommended or reuse? As I refitted mine and had no back lash and had tight spots when spinning it.they re new ones as come with coating to set the backlash

[@Weissworx]

That one we did reuse. The spur gear on the crank was replaced

[@720Growth]

What was torque for this gear?

[@Weissworx]

@@720Growth for the balance shaft intermediate gear? Or crank gear?

Quick question. If the front balance shaft has seized, would it also prevent the water pump from working? I'm having a "zero" oil pressure problem. Before the problem began, however, my engine began vibrating (not idling rough) but vibrating the way it would if you had a broken engine mount. I found the dogbone/transmission mount had failed, but after replacing it, the engine was still vibrating. Before I replace the rest of the engine mounts, I'm trying to figure out if my oil pressure and vibration problems are balance shaft related. I assume the engine would lock up if a balance shaft seized but I suppose the sprocket could just shear off and the engine would still run but not be balanced. Thoughts?

[@Weissworx]

Good evening. If the belt has snapped off the back side it would cause the waterpump failure. With a failing balance shaft you would or could have oil pressure issues and. Vibrations. I would pull the timing belt cover off and take a look to see if the belt is intact.

[@quesnoy1342]

it's a tsi. Timing chains, not belts. I think I'm gonna check the motor mounts before anything else. If one or both are bad, I replace those. Then, if vibration is fixed, I'll replace oil pump. If that doesn't fix the low pressure, I'm gonna sell the car as a project. I've already replaced the timing chain tensioner once. If I have to dig that deep into this engine again, it's not worth the hassle.@@Weissworx

[@Weissworx]

@quesnoy1342 Even on a tsi, there is a small belt that drives the water pump. When ro you see an oil light

[@quesnoy1342]

correct. I've changed the water pump belt within the last couple years. The car did not overheat when the vibration first started. And I drove it at least 30 miles before I got home. So I assume at least the front side balance shaft did not fail. It could also be some RTV bits blocking the oil pickup. VW really screwed up by using RTV instead of O rings on many seals.@@Weissworx

@Weissworx hey, did u replace the balance shaft tube ( plastic one ) on the exhaust shaft .I pulled mine out on that plastic is broken , a peice felk down the hole ... idk how to get it out , if it's a necessary to replace it with a new one

Very nice job on the descriptions and the video work. I was wondering what manual are you using and if you can recommend a location to purchase it?

[@Weissworx]

I would replace it yes. It helps prevent oil from foaming up

[@andriivoloshyn4581]

​@Weissworx can I take the upper oil pan off the engine without separating engine and transmission? 1 peice of that plastic fell down the hole and chilling where the crankshaft is ...

[@Weissworx]

@@andriivoloshyn4581 you will have to pull the trans and flywheel to get access to the Lower bolts on the rear main seal, where it bolts to the upper pan.

[@andriivoloshyn4581]

​@Weissworx I managed to pull out big chunk of that plastic , but a very small one ( like a size of a t30 bolt in diameter) don't know what to do ... I don't wanna pull the engine out , but don't want to F up the engine ... Do u think it's bad to leave that there ? Or it will just fall down to the oil pan and pick up tube screen will catch it ?

Why not use the slide hammer tool on the front balance shaft? Getting ready to do this job and just curious.

[@Weissworx]

The front shaft doesn't have room for the tool

[@ivanvega2821]

I recently removed the balance shafts out of my 2010 CC due to the vehicle having low oil pressure issues. Upon removal of the exhaust balance shaft, I noticed that 2 of the screens were blown in. The intake side balance shaft had intact screens, seems to be in working order. I guess my question is, would the exhaust balance shaft having blown in screens cause failure and producing low oil pressure issues?

[@Weissworx]

I have rarely seen a rear balance shaft fail. Most of the time it's the front that causes the oil issue. The front shaft can appear to spin freely. But I have seen when the shaft is worn out it'll cause an oiling issue

[@ivanvega2821]

@@Weissworx the intake side balance shaft seemed to be in working order. 3 of the screens had contaminant inside but it seemed to be working. The exhaust balance shaft 3 of the screens were blown in and one of the screens was missing. It appeared that it slightly melted the plastic sleeve that covers it at the passenger side end. Another observation I made was that the girdle cover (valve cover 🤷) is pretty scored up but the actual cylinder head isn’t. Both the cams are also slightly scored/scratched. Going to be replacing both cams with used but in good condition cams I pulled from a perfectly running vehicle and replace both balance shafts and button it up and cross my fingers.

[@ivanvega2821]

Well, I’m reporting back a little late but I figure I would document my experience. No more low oil pressure issues. As of right now, not sure if the cams and/or both balance shafts replacing worked. Vehicle has been running great. I was able to order the exhaust balance shaft tool. I was able to remove the exhaust side balance shaft with 2 90degree curved breaker bars. It wasn’t pretty… but it worked after a couple attempts. Also, I had to freeze the new balance shafts for a day in order for them to fit without fighting them. Thanks for the video man!

[@Azaiak272]

Any tips on getting the plastic sleeve in?

[@ivanvega2821]

@@Azaiak272 make sure it isn’t damaged. Ideally, she sure you take good note in the direction of how it comes out and that’s how I put mine back in. If the sleeve is damaged. You can find the part at the dealer. They aren’t very expensive and worth the peace of mind.

[@Pokingclams]

Hey there buddy. What type of socket did you use to torque or even take off that balance shaft tensioner. The 27mm. All the ones ive tried hits the block.

[@Weissworx]

I have a duralast 12 point 27mm the walls of the socket are a little bit thinner and clears perefectly

@thehitmanisup no problem! Glad to help

[@iancoulthard7409]

Sorry for asking stupid question why would balance shafts bend valves

[@Weissworx]

We have seen, a balance shaft lock up and snap a chain, the chain got caught up in the main chain, and made it jump timing causing it to bend valves

[@iancoulthard7409]

@@Weissworx reason I ask is I’m doing A4 2l 2005 hex Job balance shaft set up so you could understand why I asked

@iancoulthard7409 this was a non runner. So we did the check as precaution.

Can you know if the balance shafts are seized or not without pulling them out ? im trying to diagnose low oil pressure problem on an 2.0T Audi and havent got the puller tool yet, rotating the balance shaft gears seems fine by hand. Thank you.

[@Azaiak272]

Did you figure this out? I have a gti 2010 low oil pressure sitting at 10psi idle when hot, removed sump pick up and oil pump are both new so it’s either bearings or balance shafts now how would I carry on diagnosing

"Borsehung Germany" ? I live in germany, work in the automotive industry and own my own small shop. And Ive never heard of this brand. 😄 Regarding the repair: I think you did a pretty good job on the repair. But if you replace the chains its strongly recommended to replace the chain gears, too. Because the chain gears wear in, too and they wear wrongly if the old chain was already stretched (a bit).

[@GibsonMukaro]

Thanks 👍 so much

[@deejay4837]

Wouldn't it have been better to not put the springs in since that was the failure point...they got clogged?

[@Weissworx]

That's a loaded question. The screens did their job, preventing trash from hitting the shaft, but also doing its job it blocked all oil flow.
