your chain tensioner probley has broken apart and u might need a new one.
valves need adjusting,.030mm or .12
If its chain driven, Could be the timing chain tensioner! Does it also have a rattle driving the vehicle at around 2000 R.P.M?
Most likely a rattle from that area in the engine bay when cold that subsides somewhat when engine gets warm.
It means the timing chain needs replacing.
If the noise goes away when the clutch pedal is pressed down, then the problem is most likely the clutch throw out bearing. It may be the stainless steel shrouds on the exaust pipe. My 1994 truck will rattle when the engine is at a certain speed. The screws holding the metal together have begun to rust out, and the loose pieces are making the rattle. My 1994 truck does just the same. About 3 years ago I was advised by the dealer to replace the timing chain immediately for about 1600.-$CDN (typical advice for a female...) and shrugged it off ever since. I just replace the engine oil more often. I read a few times that the models around 1994 have a slightly lose timing chain causing the intermittent rattle but are of no major concern. I will post again if my engine blows up after all....
A baby in the back (with a rattle of course), or a rattle snake under the seat
Till it starts to rattle.
yes it is repace tentioners on the timing chain and remove uper chain gard
Something bad. Possibly a loose bolt. Get it looked at ASAP
something wrong with the ignition, most likely bad timing.
This is a common and unique problem with the Z24 engine. It is cause by the timing tensioner seeping oil while shutdown. The chain actually rattles on it's housing until oil pressure is built up again and brings the timing chain to the appropriate tension again. I have a 1996 Nissan Pickup with about 150,000 miles on it and it has done it since it had about 50,000 miles (I bought it new with 12 miles on it). I would assume that the constant rattling at startup would lead to a reduce lifespan of the timing chain, but it is actually not common for one to snap. One of those strange anomalies that we live with, because the trucks are so great (and otherwise bulletproof!) The god awful noise it makes when the steering wheel is turned to the limits to the right and allowed to roll forward or back is another, normal bad sounding thing!
There are many different reasons for you to hear a horrible rattle in your 98 Lancer, including a faulty engine timing. To ensure you find the right cause, your best bet is to consult a licensed mechanic.
