So much thanks for this video. I have an Audi Q3 in the workshop, from 2014. Also engine rattle and inlet cam sensor codes. Replaced the timing chain which was worn, no result. Removed the cam bridge, did the test of this video and the air came came out somewhere, instead of building up pressure in the head. So now know what to do, and that’s removing the head and check/replace the valve 👌🏻 Also go to replace the cam bridge, because the screen was popped out.
Thanks for the explanation. Very good. I just found out yesterday that on my model of engine, sometimes the manufacturer didn't install these valves. My timing chain rattle started a few months ago. Only for a few seconds on cold start up. I now think these check valves are either worn or not there.
EVERY chain tensioner video Audi and VW I've seen ALL have the screen blown out in the cam bridge....So why not remove the screen to begin with. You said you'd replace the bridge all together, so then you're going to have a screen floating around in the head again.....Your thoughts?
Hi there did this engine get a rattle noise from 1,500rpm to like 3,200rpm wen revving and did the noise went away by removing the magnetic solenoid wire plug and come back wen plugged back in??
hi thanks for the video and when you are saying that it will cause misfires and timing codes is it because the oil goes back to the oil pan or the oil pressure is lower than normal in general and yes i got one Tiguan with bad balancer shaft and low oil pressure when the oil was hot what i've notice is I usually go for a test drive and get the oil real hot and then I go into the instrument cluster and check for engine RPM and oil pressure switch closing and normally the switch should close at around 1000 rpm but if it's higher like 1300 rpm or more then I know that the balancer shaft might be worn out but first I put in a new oil pressure switch just to make sure that it not the switch one funny thing I got a few car that even with new oil 5W40 oil and OE filter the oil light would come on event with a new switch and it I would check the oil pressure with a gauge it would be within specs i would then get a new switch from a different model that closes easier then it would be ok I never had any issues with car that I had to do this. I think the switches are from Audi A4 with similar engines.
You should only use the proper part number sensors, they all different pressure ratings, if you use a wrong one the light might not come on, but the pressure will be too low.... If the check valve fails the engine will miss fire because the timing will be off, due to pressure low in the cam adjuster.... I always use a mechanical gauge to check the pressure when there is a suspicion on the pressure being low...
You can use the video on the timing chain plus the video on the water pump, in between the two you will have all the information you need, there will be only two bolts extra, the once that hold the actual balance shafts to the block
EdgeMotors, Thanks again for explaining these checks. Your videos makes me understand this engine even more. I've had 1.8t's, current B7 2.0t , B8 2.0t, 2.7t motor and this B8 2.0t is for more iffy with all these components. My current B8 2.0t A4 Avant currently runs good but no CEL or Misfires. I do however have the Low oil Pressure warning as the engine oil gets hot. I've replaced the PCV, the Oil spring tube under the Oil filter and still get the low oil pressure. Still no misfires. You still think its the Balance Shafts? Or can those check valves or Cam Bridge cause the low pressure. Just want to make before I tear this down. Thanks.
@@EDGEMOTORS That's actually next in the process. Check the pressure from the Oil pressure sensor location next to the Oil Filter housing. You know what the pressure range would be on idle and rpms when oil is warmed up?
@@EDGEMOTORS Finally got around to check the oil pressure and as it got warm the pressure drops below the 20psi requirement. So it looks like I'll need to do the balance shafts and or test the other check valves. BTW I did notice some oil leaking from the valve cover near the Fuel Pump. Looks like i'll need to reseal that. Could a leak from the Valve Cover cause a low oil pressure?
Hi How u checking valve? Pressure and should hold pressure or air needs to flow through. How do I now if is good or bad....sorry it’s bit cofusing in the video. Cheers
im working on a 2009 tiguan. it seems like cylinder block is not receiving any oil at all. there is no oil coming out of this hole in the cilynder with the cam bridge out and cranking the engine. i do see Oil coming out the oil filter port when oil filter is not installed. Possible balance shafts ?
this check valve is only to prevent oil coming back down when car is shut off . how this is going to reduce your oil pressure when car is running . please explain . thank you

Yes, but if it’s stuck sideways as it usually happens due to the valve shaft guide wear, it will not only drain the oil when the car off, but also restrict oil flow from going up…
Hey, I have new timing, new Cambridge, camshaft and when the engine is hot, at around 1500 rpm there is loud rattle noise from cams or chain also hot engine is hard to start with short crank, when it’s cold car starts with no problem. Could that be that valve ?

How many of those cambridge check valve ball have you really seen blow out? The mesh screen is notorious for coming apart under 50k kms as people have checked. Just wondering as I myself have replaced the cambridge without the screen as per vag tech guidelines.

Can this valve be replaced without replacing the chain? Also, is this common on the later 1.8 tsi engines?

Did you ever check the actual pressure?
@@EDGEMOTORS That's actually next in the process. Check the pressure from the Oil pressure sensor location next to the Oil Filter housing. You know what the pressure range would be on idle and rpms when oil is warmed up?
That should of been done first:)
At idle you should see around 20psi and higher, at around 2000 should be above 35psi...

No. It has to be pouring in order to affect oil pressure
Thank You
With help from this video I've found my check valve has failed. Do you have a part number for the oil check valve.
Thanks

I fixed mine by changing balance shafts because of no oil pressure at idle when engine hot
Did you use pressure or vacuum to check that valve? Not trying to be a smart ass but that looked like a vacuum pump
Pressure,
@@EDGEMOTORS cool i have my head apart but im not exactly sure how you change this valve? Any tips would be much appreciated thank you in advanced
