start-up noise

[TurboKA37]

already posted this in the 240 general forum and got a response saying it may have to do with timing, which is what i thought it might be:

about a week or two ago i noticed a strange noise right after the engine fires on start up. its hard to descripe but its kinda like a rattling/rubbing noise that lasts for about a second. the car is currently not being driven much, just sitting in the garage for the most part. i was just reading through some of the 240sx Faqs and came across the timing chain problems and thought this may apply. i also noticed that this only happens when the engine is started cold. what do u guys think the problem is? its a 1995 240 stock.

tell me what u guys think

first try changing your oil and filter, use a nissan filter. after you have driven it. the next morning check it again see if noise is still there if it is it may be the chain tensioner.
