Retro-gone. Posted February 28, 2009 Report Posted February 28, 2009 are they worth bothering with ad if so what do reccomend, theres nothing wrong with my engine, no rattles or smoke but i want to ensure it stays that way, i was given some Wynns gearbox additive by Leonmex to try and it really smoothened out the gearchange so i was thinking maybe treating my engine too, apparently it leaves a protective coating on all moving parts which cant be a bad thing.. do any of you use such a thing? also ive never used a lead fuel substitute but do you think i shoul start? im on the lookout for another 2.0 head so i can get the unleaded conversion done but that may take a few months.
Fiesta Steve Posted February 28, 2009 Report Posted February 28, 2009 I have no idea if these addivtives really work or not, but if its as easy as pouring something in your oil, why don't the manufacturers put in in the oil to start with. As for leads subs, I've never used them either and on inspection suffered no signs of excessive wear. I think if you are going to pay for a lead free conversion then why not wait until the engine needs it, which it may never ?
Admin Vista Posted February 28, 2009 Admin Report Posted February 28, 2009 I use castrol valvemaster plus in the alfa but don't bother in the escort as it has hardened valve seats already. Valvemaster plus is a lead substitute and an octane booster, I use for two reasons. a. I believe the Alfa engine was originally conceived for 5 star fuel. b. It's just too damned expensive to rebuild if I do get problems with valve seat recession.
Fiesta Steve Posted February 28, 2009 Report Posted February 28, 2009 I've used my car daily for 3 1/2 years without lead subs and rekon the money saved would easily cover a lead free conversion.
Fiesta Steve Posted February 28, 2009 Report Posted February 28, 2009 ...not that it needs seats yet either, it will do many more miles trouble free

Not on an Alfa V8 mate decent head gaskets alone will set you back over £200! Oh and the engine has to come out to do the job properly.

johnny_h Posted February 28, 2009 Report Posted February 28, 2009 can't recomend this stuff enough, the miltary use it in fookin EVERYTHING, it has a nato part number so if you know someone in the forces see if they can source a few litres. Otherwise Halfrauds do it etc etc...
LEONMEX Posted February 28, 2009 Report Posted February 28, 2009 glad that gear treatment worked,ive always used it in my cars & my type 9 has been trouble free for the years ive had it in my car & it does get some abuse. I always use slick 50 in my engines but i guess you never really know if makes a difference as who keeps there engines for long enough to find out?? the stuff mr johnny h has mentioned i have heard is supposed to be the dog's dansgles tough. but for me an oil change every few thousand miles don't gp a miss

johnny_h Posted March 1, 2009 Report Posted March 1, 2009 It's on the bottle's you can buy in civilian stores.
mk1super Posted March 1, 2009 Report Posted March 1, 2009 I use Ledex on my scort and tbh ive noticed it causes it to smoke a bit, maybe i used to much lol
V8ian Posted March 1, 2009 Report Posted March 1, 2009 Gearbox antifriction addatives, sort of defeat the object of syncromesh, by reducing the friction, the cones do not grip as well, and do not speed up the gears effectivly, although its not allways apparent, and the syncros have to work hard to give smooth changes, after a while the syncros die,
