pretty sure they are going out on my car.. it sounds like my car has no oil while under load but sounds ok when it idles.. any info is appreciated.. video of bad lifters? advice? things to check? doesnt sound like cam chain tentioner.. my hunch is lifters but unsure.. car also has been throwing a lean code..

what in the world is lifter? :D

It's most likely a clogged pick up tube and low oil pressure uptop. I thought mine sounded like a lifter (used to sbc) and it was the oil pickup. Try seafoam and an oil change or clean th epickup yourself. I also use lucas oil stabalizer.

What is your oil weight?
If it's 0w-30~0w-40...
then you need oil withing the engine spec, 5w-40 or 10w-40.

Then behold normal hydraulic lifter

Check the oil pressure first. It is very common to get lifter noise on a 1.8T if the oil pressure is even a little bit low. Generally, if the pressure ever get's below 20psi or so, you'll have some extra noise.

This is also the reason of ticker oil.
A simple explanation;
At idle the oil pressure is at minimal but when using higher RPM it doesn't make noise, as more oil is moving and hydraulic lifter stay full. Symptom of oil pressure.
There is just too much distance between surfaces of your hydraulic lifter, therefor oil with lower viscosity cannot hold.

using synthetic 10w 40.. ill go ahead an check the oil pressure in the next couple days.. would the lean code have to do with the lifters at all? also its pretty much in conjuction with the turbo spool.. if i get past 2-3psi it sounds like the lifters are going crazy.. ill see if i can get a video of it.. seems to intermittent aswell.. seems like when the car is cold it doesnt act up as much..

so any reason it would not make noise if its cold? an lifters would make more noise when warm?

yup.. 91 oct.. if i use anything else the car misfires bad in the mornings..

Then this doesn't look like lifter, hotter oil would flow better to the top of the engine.
Do you have any CEL? (Check engine light)

That's true, but the oil pressure is at absolute minimum when the oil is hot. So if there is any kind of pressure problem, it will show most when the oil is up to temp.

i think one of the bolts from the exhaust manifold-turbo is a little loose.. saw a small tuff of smoke when i revved it looking under the hood.. i have read that "lifter" noise can be heared if exhaust pieces are loose or cracked.. dont know how valid that is tho..
and yes i do have a code. p1128 lean code..

whats the easiest way of going about checking the oil pressure?

its the higher pitched wavy noise with the turbo spool.. kinda hard to hear.

can hear it best in the later part of the video.. once again its the higher pitched noise..

The easiest way to go about it is to pay someone to do it, lol. But you do it using a mechanical oil pressure gauge. Your mechanic probably has one, but he may have to dig it out. It isn't a tool he uses everyday. They usually are housed in a little red case (they are almost always red, who knows why), and they look like this when you open them:

Then you hook it up to the oil pressure check port. It is an unused plug on the top of the oil filter flange/housing. Here is a photo for reference (2001+ engine shown, earlier engines are similar):

The little red plug is the aux check port. The alternative hookup is to remove the factory oil pressure switch and connect the gauge there. That is the item in the red box. Both connections use a Metric 10x1.0 thread, so you use the appropriate adapter on your gauge for that. It should take a mechanic no more than 15 minutes or so to get a reading, that's after he finds his gauge. Perhaps another 15 minutes to put the car back together. You want hot (~200F) and cold readings, ideally. As stated above, the hot reading is more important as that is when the pressure is at its lowest.
