Start up rattle and pre oiler solution

[Guy63]

My car has 82k miles on it but I have just noticed a slight rattle when the engine first starts up! Can anyone recommend a pre oiler that I can buy, I note Johns article on the ( which a lot of people seem to have)  subject but I’m not great mechanically and will get my local garage to fit whichever system is recommended? I see most of them seem to come from the states , does nobody in the UK sell a system? Love to get  some feedback as I think I’d rather get this fix done sooner rather than later, thanks...

In GS 450h it should be the 2GR-FSE V6 3.5l engine. The start up rattle is somewhat standard for ageing engines of this model with the most common cause is the variable valve timing camshaft gear assembly while the engine increases the oil pressure at start up.

If the rattle disappears within 1 second, there is usually nothing to worry about. If it stays for longer - consult toyota specialist.

Fresh engine oil sometimes help to reduce or eliminate the rattle.
