220 xr8 annoying engine noise/issue

[troystanton78]

So, i have this noise, it sounds exactly the same as a slipping belt(but it isn't), it only happens whilst accelerating, usually hard, but not all the time, it sounds as if its coming from the right side of engine as you are looking at it, deep though, not a pulley or belt, as i said its not all the time, when it happens it stops when i back off, but i can slip it into neutral and keep it going at around 1500+ rpm, there is no miss or power drop or anything else that i have noticed when it occurs, although i have backed off straight away as i don't know what it is, i have had two guys give 2 totally different suggestions, 1. vacuum noise 2.timing chain bit sceptical on these, what do you guys reakon
cheers

Is it a rattle sound (Metal), or sound a bit like a knocking from motor.

I just had a similar thing with my XR6, same engine range, under power so I took it to Ford in Cardiff and they reckon it was the heat shield from cat converter, so they removed it.?? Made it a bit quieter, still sort of there so will be watching this thread closely.

Cam synchroniser I would say. Do a search- there is plenty of info on here. Very common, not an expensive fix either.

Thanks crakrz, done a search, amazing how someone has always had the same issue already, one ordered from rockauto, 67 bucks delivered

Yeah, no probs. Just did mine a few weeks ago. Some good info on here that really saves some stuffin around.

The other good thing about it is that you can dismantle the old one, clean it up, re-grease the shaft, re-assemble it and you have another one ready to go on the shelf.

Cam sybchroniser for sure. I've done mine twice in 3 months, but went from original to chinese knock off (rockauto one) and it was quiet until 2 weeks ago, so put original back in and was worse. So put copy one back in and noise gone again!
