E36 metallic "chickety - chickety - chickety" sound

[Mockngbrd]

on my 318is I've been having this very annoying metallic "chickety - chickety - chickety" coming from the front of the car, i've changed the timing chain tensioner, i've changed the water pump, changed the belts, and i've had the aircon bearings reconditioned and it went softer for a very short period of time, but it came back and is very loud now, turning on/off the aircon just changes the frequency and pitch of the sound. It sounds like a mix between rubbing two pieces of A4 paper together / flapping the edges of playing cards against each other. It's really annoying but the aircon still blows cold.

It really does seem to be coming from the aircon compressor area, should i just bite the bullet and buy a brand new compressor? Or is there any possible other (cheaper) part that could be making the noise?

Maybe a chicken-cricket hybrid got under the hood?

Have you checked the drive and fan belts? As for whether it's the A/C system's components, best to go to a reliable specialist for them to t-shoot.

Good luck! And dunt stir up the zombies with the clatter ya.

is the compressor pulley bearing replaceable? might b the cause

Re: E36 metallic "chickety - chickety - chickety" sound

yeah agree try the bearing first (if it's an option) and then the compressor

if above doesn't solve the problem then you need to convert your car to quattro.. guaranteed fix

Re: E36 metallic "chickety - chickety - chickety" sound

thnx for the tips. i've actually had the bearings redone just a few months ago.. so it's either the compressor now or the aircon shop did some shoddy work.

might try to isolate the noise by running the car with the aircon belt removed just to be sure it's the aircon making the noise too

Might be due to free play in your aircon shaft? Mine had noise coming from the compressor. In the end, replace the compressor for $6xx (kana chop)......

Re: E36 metallic "chickety - chickety - chickety" sound

Eng Soon also quote $6xx

when you changed your fan belts, did you change the a/c belt tensioner pulley? When I changed mine, there was definitely play. Causes the belt not to run in a straight line and maybe rub on something.

When they 're-con' your bearings.. did they just put in another old compressor?

My compressor had this same annoying noise.. then I took it out and replaced it with a spare.. ok for awhile then the noise came back.. finally I dismantled the compressor and replaced the bearing myself with an SKF german bearing, been fine ever since

Bearings are important.. a lot of workshops order the cheap chinese/taiwanese ones.. they last only a while before giving way.. I make sure all the bearings in my car are either SKF/FAG or NTN Japan, costs more but the car runs much smoother
