Timing Chain slap. How to reduce the noise?

[yonip]

How can I reduce the noise coming from the timing chain? I think they call it timing chain slap and they said it is due to tensioners 1 & 2. If I will use a different weight of Oil, will it reduce the slap?

How many miles do you have on it? I heard that if you hear noises from the timing chain, thats when you need to replace it, if you don't, you know what happens.

Replace the tensioners...

Replace the tensioners...

True, but while you are at it, might as well replace the chain, thats why I didn't just say replace the tensioners.

mine slaps too

i havent fixed it tho but the mechanic said it was a tensioner just by hearing it , right now im changing shocks and springs , then i have to fix AC leak, tensioner fix will be soon also, but it will be good to know how much is that fix ?$$$$$

I will be interested in hearing the amount too since everything will have to be taken off the front of the engine. Somebody said that an Inspection II is about 500 or so dollars and I believe that should include replacement of the timing belt/chain, so go figure.

Inspection II does not inolve changing of the timing chain. That will be a pricey undertaking if you take it to a shop. While the actual act of changing the chain is not really any more difficult than changing a timing belt, it's the design of the E36 engines that make it more difficult to access the chain and hence make the job more labor intensive. The engine simply was not designed with changing the chain in mind.

To answer the initial question - changing oil viscosities/weights will not change the slap. You have worn tensioners and they need to be replaced - changing the oil weight will not fix the problem.
