Timing chain replacement on 88 SSE AT 220,000 Kilometers
I will replace the timing chain on my bonnie this week.My car has now 220,000 khms
(~130K miles) because the engine is getting very noisy and I suspect the chain starting to flick on the casing
I would like to know if some of you guy had to replace their timing chain and at which mileage.
Is there any other parts I should replace at the same time since it will be opened there?
thanks

Yes, the plastic magnet that is in the camshaft timing gear. The magnets in those brittle plastic casing break free every once in a while. Might as well replace it while you're in it. Its an interrupter, and costs 20 bucks at the dealer.
You sure the noise is the chain? What kind of noise, and has it been like that a while, or just started? Hows the oil pressure too?

timing chain
i have a buddy that will be replacing the timing chain on my 89 sse the end of the month. it has 293,000km and i got the car from my aunt so i know the chain is original. it started making a "tinny" sounding rattle in the motor about a month ago. he also suggested since the car has the original water pump and it has to come off at the same time, replace it as well.

Yes the noise was validated by my mechanic.
The oil pressure is within the gauge limit.
run this car since 10 years now with synthetic oil.
I add now a oil treatment BARDHALL type at each oil change to improve the compression performance. Engine use to run smoother but now the timing chain is audible clearly.

Yes, but don't the timing chains stretch? Wouldn't they say, stretch to the point where its affecting timing slightly? Meaning, the engine would not feel as new as it did when delivered from the factory? Just curious.

i know with my sse, the friend who is changing if for me has had several bonnevilles and lesabres so i'm trusting his opinion when he says the noise is the timing chain. i've also started to notice the last few days it occasionally starts, backfires a bit, stalls, and then starts again, which if i remember my mechanics from the old days of v-8'*, is a sign of timing trouble.
i did drive the car on occasion when my aunt owned it and i do notice a difference in power from when she had the car to now.
the car had 270km on it when i got it at christmas and has 293km now( about 15,000 miles driving ) and until a few weeks ago when the noise started i hadn't noticed any significant change in the car. maybe it takes a while for it to get to the point of no return and then it goes quick.
anyhow parts have been ordered and it goes in next week to be done so i will post the end result!!!
