Hi guys,

 

Can someone help settle a debate, when setting your timing you turn your crankshaft at the belt pully clockwise until the timing bolt stops it? And when adjusting your camshaft you turn the camshaft counter clockwise?

 

I've never had the pleasure of working on these engines before and the service manual just says turn in direction of the engine rotation. Assuming that direction is viewed from the flywheel.

 

I've got a mate trying to do his own timing, sounds like a disaster waiting to happen going to help him out with it but cart remember which way everything turns. 

 

 

 

 

You don't say which engine you're talking about, and it's not clear what car, as your profile says Octavia, but you've posted in the Mk2 Fabia forum.

 

However, I'm reasonably sure that the engine will rotate clockwise when running, looking at the crank pulley of the auxiliary belt run, or the timing belt pulley.  Cam(s) will rotate in the same clockwise manner when viewed from the same end of the engine.

 

If you tell us which car and engine type, an owner of such an engine may be willing to run theirs briefly with bonnet open to confirm.

Sorry, new to the forums, I have an octavia. 

 

Car were going to be working on is a FABIA mk2 1.2tsi CBZB

 

My Octavia turns clockwise at the belt pulley side. 

 

Problem is my mates already drained oil and coolant so we cart turn the engine over to see which way everything rotates. 

 

Thanks for your response.

 

Here's a youtube video that you may/may not have seen, looks to be quite detailed including lots of workshop manual 'borrowing'. Covers more than just chain change.

 

 

Looks like an awful job TBH.

The answer appears at about 5 seconds into this one: 

 

Thanks pal.

No probs, and let us know how you/he gets on please.

Convention is engine rotation always clockwise viewed from the exposed crankshaft pulley, even on the oddballs like the FWD Triumph 1300 that have a starter ring gear carrier on the front that many think is the flywheel.

 

You could turn you engine over by engaging top gear and pushing the car forward or cranking it momentarily but you wont need to, it will be clockwise rotation viewed from the crank pulley as will the camshafts.

Hi, 

 

Just a little update for anyone interested.

 

Got the new chain on. The work went a lot smoother than I expected. We had to adjust the cam slightly before we locked it up but other than that straightforward. Engine was throwing P0340 cam shaft sensor code before. That's cleared and isn't coming back. The car still wont start still and no idea why. It was stood for a few months before we sorted the chain. The battery is new, spark plugs are all working. The engine is trying to crank up but there is no combustion.

 

The old chain was stretched slightly so I suppose it's possible it could of jumped a tooth or two. There not been any signs of engine damage but think it will be wise to test compression.

 

Fuel filter looks a bit old so thinking of replacing that but didn't think that would cause it not to start. Fuel rail pressure is acceptable .

 

@Alexp993

Is this an early 1.2 TSI that had the chain tensioner pre upgrade and you have now fitted the updated kit of chain and tensioner to?

Yeah, manufactured late 2010 registered early 2011.

 

I'm pretty sure chain has been changed before. New was same design the only difference was the new one had one black link. The old one didn't, Both sprockets were the same but were replaced with the chain anyway. The screw that holds the chain guide in place had been pretty much rounded off. I had to use mole grips to get it out so someone has definitely been at it before.

When it's cranking does it sound normal, like it's compressing OK? Or not?

Yeah sounds normal to me. Hard to tell from a recording but took this earlier.

 

No, that sounds like it isn't compressing.

Possibly the hydraulic lifters have drained down while it's been sat. Remove spark plugs, disconnect injectors and spin it on the starter for a bit to get some oil pressure into them?

Compression test would be the first thing I would do, doesn't sound very good to me but it could just be the audio and unfamiliarity with that engine.

 

Could try a drop of oil in the cylinders if its been stood a while and there has been lots of attempted starting

Worth a shot. Will give it a try thank you. How long would you try crank it up for? Its probably had a good 30 - 60 seconds already, spark plugs were dry after which led me to think fuel system. Cars at 70k. 

I dunno, another minute?

 

Given that you have already cranked it for so long, Easy Start used with care would be 1st option to rule out fuel injection issue and give you a chance to hear any un-expected noises as if it does fire it should only run for a few seconds..

Another update. Sorry its been a while. 

 

Its not good news anyway. Decided to get an inspection camera in the cylinders to have a look at the valves.

 

None of the intake valves are fully closing as they should you can see marks on the psiton heads caused by it slapping the valves.

 

Going to strip engine down and rebuild, provided cylinder block/head hasnt warped. If it has i think it will be scraped/broken up. Not enough money in the car for it to be worth sorting

 

Least something will be keeping me out the pub once they re-open.

 

I don't have proper tool for pulling the lambada probe out. Was going to buy one. Anyone got any recommendations?

 

Thanks

Alex

 

 

 

☹️ Oh dear, I did wonder what ever happened with this.

Looks like you were right unfortunately, easy with hindsight but the indications would have been there, sometimes as rude as it may seem when a disaster waiting to happen type of person asks for your help you have to interrogate them as to whats gone on before for their own protection, very often they will hide or forget significant things like "I was driving and there was a jerk, a tinkling noise and the engine stopped, when I tried to start it it span over very fast"

 

Its a shame that you have spent a lot of time trying to help and working on the persons car for no result.

Yup, i was with in the car when it first happened. It started as a misfiring engine I'd hoped we would get lucky as the car was on the drive when it started and it hadn't been driven on. Should of thought about getting an inspection camera first. And yeah shame about the result but I do it cause I love it. Looking forward to stripping the engine down completely now. Thats the easy part though.

Also considered we could of set the timing up wrong but if thats the case I've no idea how, the workshop manual was followed to the letter and I did the testing procedure 4 times. Im not a fan the crank locking bolt or the camshaft key. Sounds daft but seems too straightforward for it to be right.
