I'm not usually one to endorse the ramblings of these additive companies...

However after using both their PAS additive and Transmission stop slip, both of which worked really quite well I decided to try their oil additive.

My Old V8 recently started a nice Cam follower tick on cold start and when Hot, i'm assuming because the oil thinned out and that tappet lost prime..

At idle it was irritating the hell out of me so, whats to lose with the Lucas?

Consistency wise it is very sticky, it leaves greasy strings like hot glue, so be wary of that!!

I drained out some of the 10w60 to make room..

New stuff took an age to pour in, in hindsight I should of warmed the bottle up..

Filled up

A good hard drive ensued, and upon returning home the TICK was no longer present, even with my ear in the arch which is where it was really prevalent..

I've since Started it from cold too, and the tap has disappeared there too...

So it sum up..

It does work in some cases....

Here is the Cold start rattle...

Probably just me, but all I hear is fan roar. Are you saying this is the sound after you used Lucas, or before?

'Tis before.

There is a faint rattle lol

Gone now after lucas!

I was thinking belt idlers too. Maybe it's just me but I would have thought a cam and followers would have been higher up the list of priorities than a Tornado?

Hiya Richard.

I have the Cam and followers to fit...

Just gotta find the time!

There used to be no end of magic potions to disguise a worn out engine, STP was the usual one used to get rid of the big end clatter on a cold start. They would work after a fashion but not for long (only until you'd managed to flog off the old dog in most cases), although bunging a litre of EP90 into the sump did much the same job. I tried Lucas power steering stop leak as I was told it was wonderful stuff and would cure a leaking power steering rack. It didn't, made no difference at all.....

I am trying the Xado on a couple of engines here, but so far not seeing much change ...
