Engine noise

[Jamie22]

hey guys Im new to this forums hello to all. but I have a problem with the misses car I don't know much Toyota camrys 2004 model but the girlfriends car has like a timing belt/chain noise coming from the engine plus the oil light comes on at the dash. now the oil is full so it has oil in there and im think it could be a oil pressure problem or maybe oil pump not working probably or on it way out or I just don't know and another thing I could be wrong on this but do the 2004 model camry use a timing belt and don't they have to be change something like every 100,000ks?

Sounds rather nasty. Time for a workshop mechanic's investigation.

I agree with what you've suggested. It's fairly close probably.

Not a job for a plain home mechanic. Good luck.

if its a v6 engine then there's timing belt. if its a 4 cylinder engine, then it runs on timing chain, which doesnt need replacing

Sorry, but I beg to differ - that is, 'from a general point of view'.

They are all belts between 1990 and 2002, (to the best of my knowledge, see link).

The current question then is that it would be a chain in that case.

Why? He is correct.

The Gen5 Camry came in 2 flavours: V6 (1mz-fe) and 4-cylinder (2az-fe). The 1mz uses a timing belt and the 2az uses a timing chain.

I don't know what the service interval is for a 2az (Jeffy may know; he has one and probably has access to the manual) but the 1mz recommends replacement of the timing belt at the 150k mark.

I had a look at the Service manual for 2az-fe, it didn't have the recommended Service interval for Timing Chain replacement...

[jeffy]

Timing chain replaces at 150,000 kms, well thats when i got mine replaced i mean.

service intervals are 7500kms or 5000kms "under extreme conditions"
