92 318i ticking\tapping unsure what it is

[pcmase]

Well let's start by saying I just purchased this vehicle a month ago barely running has about 240k I've pretty much worked everything out just got it on the road last week after a few days it started tapping and its getting louder I know a little about engine but this is the first BMW I've owned and better to get an opinion from more knowledgeable ppl then trust locals who think they know. From what I've researched im thinking it's either my chain tensioner or lifters I don't notice any loss of power it changes with rpm but sometimes I hear it and it will go away at 3k rpm and come back when below that I've had an idle problem since purchase but the tick changes when idle fluctuates also I have no belt on my AC but idles better with AC on but that's not the important part if someone can give me a more definite answer someone who maybe had same issue I can start repairing it before any more damage occurs thanks in advance I'll try posting video link if it's allowed

Too hard to pick, I'd get the new style chain tension piston for starters.

Or try the piece of wood trick.

I'm gonna Google that wood trick that's new to me I'm already in process of tensioner seen the stories on here. I've noticed the tap stop and my idle smooths but only for a half of second and comes back more annoying with the stares I get being I'm the only e36 in the surrounding cities and I'd like to get this running nicely even if it takes new engine I plan on pulling valve cover to check and see if there is anything loose or gunked it does have 240k so maybe a good upper inspection is needed not a bad car for 1000$ so far

Wood trick is great, place wood where you think noise is coming from place ear on the other end.
Repeat till found.
But a new chain tensioner wouldn't hurt, they have upgraded them!

I'm starting to think this car hates new parts or me because out of no where the ticking stopped only does it slight tick on cold start so I'm assuming lifter problem . but now my clutch is starting to grind so another project is around the corner

[Darky]

Did you replace something?

Remember both these problems are from oil, bad oil, wrong oil or not enough changes!

I haven't had much time to do anything to it the last thing I did pull the oil filter which was crushed a little inside the holder and put a new one so that makes sense in restricting oil flow
