Audi80 engine sound/tappet noise--> need opinions
Hey!
I'm just trying to get some opinions on the engine sound. I guess one or more hydraulic lifters are ready for replacement judging by the tapping sound? Besides the tapping sound there seems to be some other sound like a whining? I don't have access to another audi so I don't know if this is a normal sound for this engine. Here's the vid if anyone wants to take a look: http://www.mediafire.com/watch/ipjv9...di80engine.mp4 ThanX!! |
yeah, tappets dont sounds too healthy
whining... dont know, maybe a distributor? |
thanx replying!
Yeah, I've been thinking of ordering and doing them tappets soon. I don't like the sound at all and the engine isn't working as smooth as it should. Distributor has been rebuild. I'm thinking maybe alternator bearing could make that sound -.- |

I'm adding oil when heard tapping noise on starting up and no change oil 5 year since installed with 24.000 miles just keep top off when needed because, my Audi (10 Valves A/T, 249.400 miles now) has an "Engine OIL Cleaning Device". Good luck. x19 |

Got no A/C hehe :P
But you could be right with the power steering pump as it's still the original.... It has been making a screeching sound lately when I lock the wheel to one side, but after correcting the belt tension it doesn't do that anymore unless I force the wheel and again only sometimes (fluid level ok). As for the oil, last time it got Shell helix 10w40. Oil level fine, no detectable oil loss between changing intervals, so that's great :) So today I ordered some new tappets from ebay: http://www.ebay.com/itm/170615073673?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AITAbout 16$ less then from a store here.... I plan on doing timing belt, tappets and water pump for now. I've been thinking of doing the head too, but not sure though. The car's been mostly in the garage as I've been renewing alot of stuff and I wanna drive it for a while now :D When you watch the engine it regularly shakes/jumps a small bit (sounds like a small pop from exhaust, barely noticable though), so I guess it could be related to the tappets as I've changed all ignition related stuff? Also when I cruise in any gear without throttle it gets jerky around 2K rpm and then gets still again aproaching min rpm. Very strange! |
did it start making that noise after you fixed the screeching sound?
any idea what oil pressure you are pumping out? |
I drove around earlier and I noticed the screeching sound appears primarily when I lock to the left o.O not on the right for now.... strange indeed.
I could try record it tomorrow. I think the "whirring" background sound was present before I changed/adjusted the servo belt. As for oil pressure, no, I don't have a clue. But this gives me the idea to finally install a pressure gauge :) I replaced the valve cover gasket a month ago and it didn't occur to me to check the tappets for up/down play. I read they aren't allowed to have any free play. |
there is going to be some play no matter what, otherwise they would not move, you should be able to measure between the cam and a tappet with a feeler gauge. but i don't 100% on your engine what those measurements should be. btw, you engine compartment look clean!!! :)
p.s. you should be able to install a set of these Nick's Black 90 - 3B Swap: VEMS - Boost! :: motorgeek.com :))) |
also check if the noise stops when you press the clutch in
