Engine missfire and low power!? How to Check Twin Spark correct timing

Hello guys! How many times!? "after changing the timing the car pulls little on lows and missfires" and until now every time I get a car like this, the solution was to synchronize the engine correctly! There are exceptions, yes. But anyway, when looking for a fault, you always have to start with the basics, when checking the correct engine timing.
In this video I also show you how to change the belt itself, how to tension it properly and how to readjust the timing of the engine after installing the new belt.

looking for information on a camshaft sensor change on my 147 2.0TS after being diagnosed and going into limp mode... your video not only showed the location and what needs to be removed to get to it but also showed how easy it can get damaged by a (mis-shaped)bad pulley on the back. I will also now be doing the cambelt change along with all the other parts that make sense while doing so. A great video that goes beyond just doing the job... doing it with precision and care...what all Alfa's need.👍

@@alfaromeonoproblem No problem. Btw, any reason why a new tensioner would not hold it's tension? If set with the correct tool.

[@alfaromeonoproblem]

@thomass8118 hello. It will move wildly when the engine is spinning, even by and. It's normal. It's dinamic. But it should be in the correct spot once you time it slowly

[@DashCamSerbia]

Amazing work. The procedure is not simple and takes some time, so I bet that is why mechanics don't bother doing it and just do it close enough ("customers are too stupid to notice anyway, right?"). That is why it is worth doing it yourself (if you can) or pay it (an arm and a leg) to be done properly at the official dealer. I heard it is the similar procedure with the 1.75 TBi engines, and that is why most of them are out of phase usually as well? What about the 1.4 T-Jet (FIRE) engines though?

[@alfaromeonoproblem]

Hello. That is correct. This and other engines that require locking tools are often out of timing. Very unfortunate to happen, mainly when the technician knows he's cutting corners...

[@kingissback]

Hello. What is the purpose of the green wrench you use when tensioning the tensioner ball of the timing belt? And can I get this key too? There is no Turkish option in the subtitle feature of the videos. That's why I'm having a hard time understanding. thanks.

[@alfaromeonoproblem]

Hello. There are two types of green wrench to use. One for the belt tensioner, the other one for the 2.0 that has the belt for the balancing shafts. That belt has a tensioner and with that a different wrench. The tools you can by online and it on a store for workshop tools.

[@kingissback]

There is no this key in my city. Is there a different way to stretch instead?

[@kingissback]

By the way, thank you for your reply.

[@kingissback]

I fitted the channel of the timing belt tensioner to the pull and then tightened the bolt by tensioning the ball with the help of a crowbar.

[@LyTaS2796]

Hi! Thanks for amazing video!!! I’m trying to do correct synchronization on my 2.0 twin spark engine after changing timing belt and I really need your help :( No matter what I do…. exhaust cam is always shows bad on my cam tool. I’m using gauge and locking tool for TDC and I can achieve intake cam synchronization correctly. What I’m doing wrong? Maybe when I’m rotating engine back to TDC I screw something up? Btw to rotate engine back and avoid touching crankshaft nut, I’m using auxiliary belt pulley and hands (not sure if I can do this simply with my socket wrench) 😄

[@LyTaS2796]

I need to also mention, that I get bad timing on exhaust cam when I spin the engine. Until I spin the engine I make everything perfect 🙄

[@LyTaS2796]

Maybe I’m doing something wrong with the belt tensioner… Because it seems that it can’t stand in place sometimes…

[@alfaromeonoproblem]

@LyTaS2796 hello. Can you adjust the exhaust sprocket?

[@LyTaS2796]

@@alfaromeonoproblem Yes. I do everything as you show in your video. I rotate the engine clockwise till my cam tool sits correctly on exhaust cam. Then I loosen exhaust sprocket and rotate engine with auxiliary belt pulley by hand back till I get TDC. Then I tighten the exhaust sprocket. After that I remove everything and try to rotate my engine clockwise once and I always get my exhaust cam off from timing tool by roughly 1 mm to the left... :(

[@alfaromeonoproblem]

@LyTaS2796 ok. Normally that happens because the sprocket is not all the way to the right when the belt is being installed

[@Zion-jw3gm]

FINALLY!!!!! It's about time, THANK YOU, THANK YOU, THANK YOU. Last year I was so desperate and had no help. I did do my belt for the first time, but did not know how to adjust the intake and exhaust which were both out of sync slightly. In the end I still had to take it to a mechanic to adjust it at a painful cost. Knowing I was so close to understanding this made the experience even more difficult to digest. Hopefully I can find a crank lock as I didn't have one, without it it takes a long time.

[@alfaromeonoproblem]

I had to replace camshaft sensor on my 2.0 jts, did it myself, but now, as I saw your video, next job will be the replacing of timing belt, as I have the spare parts for almost a year !Hopefully I will make it ok! I have 2.0 jts cam lock tools and I was wondering if the crankshaft locking tool is common for 2.0 engines!

[@peterholland8380]

Oi Bruno! About the crankshaft locking tool: I have an Alfa Romeo 147 1.6 T.Spark Eco 77 kW/105 hp and I don't think the crankshaft locking tool you showed ─ or any crankshaft locking tool for that matter ─ can be used with this particular engine to determine TDC. Can you confirm this? By the way, I have watched many others of your videos and learned a lot of them! Obrigado from the Netherlands

[@alfaromeonoproblem]

Hello. The eco engine doesn't exist here in Portugal, I do not have any experience on it.. sorry. But being similar to the 120hp, I believe it should be the same. Now the cam locks, those may be different.

[@PeDe-uj9er]

Brilliant. One question. After tensioning why did you not leave the cam sprockets to rotate without bolting and leave the cams in place and turn the engine over without cams , spread the belt tension and then tighten cams?

[@alfaromeonoproblem]

I'm not sure i follow your question. Bur leaving the sprockets loose and rotating the engine can damage them and the valves

[@sig-75]

Good explanation, you are good technician, but I'm Italian and in my city, a few car repair mechanics use this method. They do by signs. How are the symptoms of a incorrect procedure, for example if the motor started even? Low power, detonation, or other?

[@alfaromeonoproblem]

Hi, great instructional videos! Any idea what could be causing a build up of cambelt dust (esp around the tensioner) soon after a 166 3.0 v6 skf cambelt kit change? Engine runs fine but belt seems tight even with tensioner set correctly, so that upper fixed idler has thrown its grease out. I can't see any obvious errors.

[@alfaromeonoproblem]

Hello. A few years ago I saw some tensioners with problems, new they were croken and did just that. Is the belt straight?

[@jameskirk7746]

@@alfaromeonoproblem Hello and thanks for the response. The inner edge of the belt has a very slight wear from touching the tensioner guide but otherwise ok (after 3 months/1000km). I swapped out the belt kit as soon as I saw the ejected grease from the failed idler; when I took off the tensioner I saw dust all over it. I fitted a new SKF belt kit 10 days ago and have just checked behind the covers and the dust is back! Also the belt makings are imprinted on the roller bearings again. 2nd kit was definately not too tight - did a dynamic test to view pointer position. Unlikely 2 belt kits are defective from different suppliers. Any bad fitting techniques could cause this? Surely this is mea culpa? Getting despondent. Just ordered a 3rd kit, Gates.

[@chrissavage5966]

I think folk sometimes misunderstand what the 'cam locks' are actually for and use them to hold the cams when loosening/tightening the pulley bolts....which rips out the bolts holding the cam locks to the head because they don't go in far enough, hence the example here where someone had to change the bolts from M7 to M8. Don't know what else you could call them to try and avoid the confusion though!

I typed a great long comment about timing marks but it hasn’t appeared. Weird, but I’ve had this a couple of times on YT lately. Anyhoo, I’ll try again! Bruno, your main point about understanding is key. I had a 12 valve Bussu in a 164 many years back where the timing mark on the cam cap was 1 tooth out. Those marks always looked hand-done to me! Long story short, after much time and messing, I went back to basics and timed it using valve lift and crank position from the cam data and that sorted it. I later came across the template you can use on the camwheel marks. So much better, and always accurate as those are machined in.
