I remember the local mechanic looking at the timing belt on the sons GF's Astra,i think it was.
His comment was if the writing on it hasn't disappeared,it won't need changing.[bighmmm]
No,i said, just change the bloody thing,it looks to me as old as the car, which was about 15yrs old.

Having just done my belts @195k they looked good with no visible sign of age degradation, pity the oil pump didn't fair so well. Tensioner broke off 2 months ago but luckily I was stationary in my drive when it went, 1 slightly bent camshaft and a couple of broken cam cap bolts was the only damage. Tore it down for a full inspection examining each component.
Gave the intakes a thorough clean at the same time.https://uploads.tapatalk-cdn.com/202...2247422260.jpghttps://uploads.tapatalk-cdn.com/202...4be7efa85a.jpghttps://uploads.tapatalk-cdn.com/202...d18c4acfb3.jpg
You were extremely lucky there loanrangie.
If the belt was in good condition it would suggest the timing belt had been changed at some point but not the oil pump.
If the belt was original then that is amazing.
Just shows, if you don’t know if the oil pump has been upgraded, get it done ASAP.
Yea they are all post 09 engines I believe.Quote:

The new housing has more metal and gusseting in the casting around the tensioner bolt hole.Quote:

Definitely a miraculous escape.
Yes 07 build MY08, i was under the impression the belts hadn't been changed by my talks with the 1 previous owner but reading the date markings on the belt it seems the belt was dated after my car was built but same year.Quote:

i was very lucky and got away with just $250 worth of parts not inc the pump and timing kit which was being replaced anyway.
Engine is running great which was a huge relief as i had envisaged fitting a territory motor.
I will add that i understand why workshops would lift the body to work on these,i think i damaged some muscles while lying over the motor and trying to get my hands down the back to reach some of the fuel belt cover bolts. absolutely no room to more so i had to come up with some novel methods to get the job done.
Lucky it happened during lock down since i was working from home and i had the time to strip and inspect and plan my attack.
And they all say the 3.0L is quite a bit more difficult to do.[bigsad]Quote:
