Thread: sticky valve fix

What sort of engine? Hydraulic lifters?
I run a small amount of old fashioned redex (upper cylinder lube) in all of my vehicles both current and in the past, swear by it. Did 400,000 k's in my last Subaru, still going fine when I sold it.
If it is a lifter problem, try some subaru lifter treatment (available at dealers), then change oil and filter. I have seen this work wonders in some older gummed up engines.
Depending on the engine, try removing the valve cover and squirting a thin oil (upper cylinder lube?) around the valve stem, this may work depending on the quality and or type of valve stem seal you have.

Redex,Morey's,remember Golden Fleece or similar upper cylinder cylinder worked well on the side exhaust valves on my old 2.6 litre series 11A.

remove rocker cover & rockers, make adaptor to put compressed air in spark plug hole. remove valve retainer and spring, grab valve in cordless drill chuck,

release compressed air - spin valve , a bit of brasso and WD40 on the stem & bobs your uncle,

put compressed air back on (so you dont drop the valve) and reassemble.

Given you've posted in the RRC section are you referring to a 3.5/3.9 V8? If so, give it the 'goingbush' treatment and, if as I suspect it's the exhaust valves, remove the valve stem oil seals...not needed and their removal assists in reducing further buildup... let's know how you get on ?

Yes I remember it well!
I always put a small bottle of Golden Fleece "Upper Cylinder Lube" in my motorcycles and a large bottle in my cars. It was always in those miniature sized (choice of two sizes) oil bottles near the bowsers. Got the idea/habit from my father, seemed like a good idea at the time but not really sure if ever did any good, but probally didn't do any harm though.
Probally softer on the engine than the "Liquid Tungsten" that was in CX3! :-)

Take the air cleaner off and tip some two stroke oil down the throat. Warning, do this in a well ventilated area - it will generate a LOT of smoke. Seen this done (and done it myself) many times.

Cheers,

P.S. Make sure your neighbours are not working for the EPA.

I thought the main reason for sticky valves was a build up of carbon /varnish/combustion gunk on the stems. So 2 stroke oil acts as a solvent for carbon/varnish etc... is this correct?
