Sticky Lifters
Discussion
I have a ticking noise from the engine about 70% of the time. Been through many things (EMG, compression test etc) to diagnose but could be a 'sticky' lifter.
The fact that it WILL go away completely some of the time leads me to think it's not:
Piston Slap
Blown Ring
Noisy Cam
It does seem to coincide with lumpy running so it may well be.
Elsewhere on various forums, the advice to clear a sticky lifter has been to:
Drain out a few pints of the oil - add 'as much oil as has been drained out' of Automatic Transmission Fluid (ATF) and run the engine for 500 odd miles and then complete change of oil and filter.
Many may be horrified by this but ATF is a high detergent lubricant and pretty much the same stuff as you'd pay £12 for a little 500ml bottle from Halfrauds.
- What does everyone else think?
- Has anyone had a sticky lifter cured by adding those 'Hydraulic Lifter Treatments'.
- Do lifters often stick in RV8's?

The thing is - the Cam and lifters were done not 7000 miles ago!
I do do a lot of small trips to work (4 miles) and back every day, and it has been cold recently too. I've heard that can be harsh on the oil. Incidentally, I have very little oil pressure when idling warm. It's about 33 at cold start idle and just off the ' 0 ' mark when warm idle and about 30 when at motorway speeds.
I'll change the oil + filter, clean the injectors, get the AFM & Lambda mixture looked at professionally and if it's STILL running rough and ticking then I'm going to strip it down and rebuild it - on the bl**dy street if I have to!!!
