Paul Amey Posted Saturday at 16:22 Report Posted Saturday at 16:22 (edited) Does the bell housing to gearbox gasket need Hylomar on it on reassembly? (Vitesse 2.0, non overdrive). Edited Saturday at 17:07 by Paul Amey
Colin Lindsay Posted Saturday at 19:32 Report Posted Saturday at 19:32 No. It does need a gasket but unless there's some significant deformation or damage you won't need any. Unless of course you WANT some, in which case, add as required.

JohnD Posted Saturday at 21:38 Report Posted Saturday at 21:38 It's more expensive than Hylomar in a tube, but an aerosol of the sealant makes spreading a thin, even layer much easier! https://www.merlinmotorsport.co.uk/p/hylomar-universal-m-aerosol-gasket-sealant-hmmaero-200m?vat=on¤cy=GBP&utm_source=Google&utm_medium=ShoppingUK&utm_campaign=ShoppingUK&gad_source=1&gclid=CjwKCAiAjKu6BhAMEiwAx4UsAuCqBkwrfxQIPK-3vKRmloVUrNZz19BjKl5Ial4ONlk8oBce1O9RXxoCGIAQAvD_BwE John

I was thinking more in terms of oil leaks but that will help the gasket stay in place, although I usually stand the gearbox on its' end, position the gasket, then lower the bellhousing onto it and bolt through. Obviously with no oil in the gearbox!
Pete Lewis Posted Sunday at 10:07 Report Posted Sunday at 10:07 not really but a thin smear if you like its a hard mating fit you dont want sealer making a slippy joint you do need a copper washer or sealer on the lower bolt that is a bore through to the oil Pete

I'm aware of the bottom bolt copper washer.
Paul Amey Posted Sunday at 19:46 Author Report Posted Sunday at 19:46 So, regarding oil, I believe the manual says EP90. I have a litre of EP80W-90, will that be right? I'm told you can't buy straight EP90 anymore.

If it's going to be hard to get I'll invest in a couple!

Yes, I've spotted the one I have is GL5 which would react with copper or bronze, so that's not going in!
johny Posted Monday at 07:01 Report Posted Monday at 07:01 GL5 COULD react to yellow metal. Highly unlikely these days but read label and decide...
PeteH Posted Monday at 07:33 Report Posted Monday at 07:33 Google comes up with the following:- GL-5 gear oil is not recommended for older cars because it has more extreme-pressure (EP) additives than GL-4 gear oil, and the additives can react with copper and bronze: EP additives GL-5 gear oil has about twice the amount of EP additives as GL-4 gear oil. These additives help the oil function under extreme pressure. Copper and bronze The sulphur and phosphorus additives in GL-5 gear oil can react aggressively with copper and bronze. API specifications API GL-4 and GL-5 are specifications set by the American Petroleum Institute (API) that determine the performance characteristics of gear oil. The API specifications for gear oils are not backwards compatible with each other. For older vehicles, you can use a mineral oil based lubricant that is formulated without EP additives. Some companies, like Millers Oils, have developed products specifically for older vehicles. I topped up the Axle in Plum, back last year, with GL4 that I had on the shelf for a while. Availabilty of GL4 does not appear to be an issue, But the prices vary from around 21 quid for 5 litre, to the stars I think. Double what was on the container I used last year!!😭 Pete
johny Posted Monday at 07:49 Report Posted Monday at 07:49 yes we do need EP but the high level protection of GL5 is wasted on our cars so not worth buying it. However the standards dont dictate the additives used just the performance so GL5 can be made with non yellow metal aggressive additives and this should be indicated on the label...
johny Posted Monday at 08:22 Report Posted Monday at 08:22 This make for example shows a GL5 spec thats ok for brass...
Paul Amey Posted Tuesday at 21:00 Author Report Posted Tuesday at 21:00 I'm ordered some Castrol EP90 for the gearbox.
