Hi all,
Just put a vr6 in my mk3 golf gti, finished fitting it a couple of days ago - seems to be a funny noise coming from the engine, not sure if its the timing chains.
It looks like they've been done before, so i'm not 100% sure if the noise is coming from the chains or not. Sometimes when i start it theres no noise at all and it sounds all ok, and then the noise will suddenly come after a while.
I need to replace my clutch, not sure if the noise is possibly coming from there but when i put my foot on the clutch the noise is still there, but sometimes it'll go and then come back again.
Don't know much about the vr engines, so wouldn't really know where to pinpoint the noise or where it could be coming from.
Dont know if theres anybody on here whos had the same or a similar problem or if theres anybody in the Birmingham area who i could drive to who knows a bit more about the vr engine?
I have got a video of when i first start it and theres no noise and then when the noise is there but i'm not sure how to upload it??? :undecided:

I dont know to much about these motors myself but I did own a VR6 which did have a rattle from the timing chain.The sound on my old car seemed to come from the top of the head on the passanger side kinda rattled more when you reved the engine etc.The VR6 owners club is a good forum to join if you have a VR there is plenty of info on there about the VR :wink:
-
I would suggest it is in your best interest to change that chain asap!
-
cant you check the tension by taking the cam cover of?
-
You would have been better to replace the chains before fitting the engine, if it needs the chains doing your looking at engine back out.
It is major work to replace them.

Or gearbox out...
The chain don't normally fail on their own, it's the guides that break up first...
-
Hydraulic tensioner may be clogged/failing or your oil pressure may be low, this can give intermittant rattling of chain.
Best just to do the lot in one hit and buy a kit.
Can be done with the engine in car but is a bit tight and fiddley, always best to to belts and chains before you stuff it in :grin:
-
Just chuck some thicker oil and/or some sawdust in :grin:

WIN ^^^

With the engine running stick your head at the gearbox end of the head, if you hear a rattling sound, then as AudiA8Quattro said, its likely to be a failed chain guide. Mine rattles a little from time to time and I will be doing the chains etc when I do my rebuild but they have been like that for around a year now and has never got any worse or caused me any problems.
I suggest saving up a bit of money and getting them done but I dont think its life or death right now :wink:
As already said, it can be done with the engine in situ, but for the sake of an extra gasket, a couple more bolts and a few more hoses, I would just take the engine out :cool:
-
I agree about the chain guides, later one's (all obd2 cars?) were plastic and usually go around 100k!!
only about £10 for the part (later model) but while it's stripped it's worthwhile doing the chains too
-
Also early upper tensioners were only hydraulic, later were also spring loaded.
This is what the dealer told me.
The tensioner could be clogged as already stated, the later tensioner would be better...

They are sprung loaded to stop the chain going too loose on engine stop, and irc once you have released the spring its a done deal and need a new one if you messed the timing up :lipsrsealed:
Even worse if find out after putting it all back together :lipsrsealed: fecking spastic....

Nice one for the replies lads
Mine sounds a little like the problem benvictors has, think i'll probably end up rebuilding mine after christmas.
The most common thing people are saying is a faulty runner and it being clogged up, so for now i might just try and get some better oil - not to keen on the sawdust idea :grin:
Does anyone know what the best oil to get for a vr is? Dont know if the oil i got from the car shop up the road from me was any good.
Also wondered where i could get the timing chain kit from??
Little bit off topic, but i've got 2 sets of wheels, bbs replicas which are on my car at the minute and a set of 17" audi tt rims - i'm after a set of standard vw or audi wheels 16" or 17" with stretched tyres on.
Will put some pics up later of my wheels and probably in the classifieds section as well, & also a pic of what kind of vw or audi wheels i'm after

You want Quantum Synta 10w40
I got 10 litres from the dealers the other day for £35!

Great thing about doing an engine swap you realise just how easy it is to remove/install the engine, just time consuming. I did the same, bought a vr6 engine for my mk2 and put it straight in as it was only on 65k. Only problem was stuck thermostat & cracked housing.
It depends how bad the chains are. If they are not that loud then just don't rev the tits off it, make sure oil is at the correct level and keep an eye/ear out for the noise getting worse until you can replace them. If they are getting worse then stop driving it. If they are bad they sound like marbles rattling around. Youtube has vids of rattling chains, some sound horrendous! If left the guides will break up and get chewed to pieces in there.
VW intended the chains and guides on the vr6 engine to be lifetime parts. Only problem is they wear out quickly if the engine has been run low on oil, or around 100k if not maintained as well as they should have been.
