Now fitting a new genuine Honda cylinder base gasket.

Is there any reason why it's green on one side and blue on the other (i.e. does it matter which way up it goes, as it fits properly both ways up)?

Ta, D.

Thanks BryanJ. I guessed as much, but always nice to hear from a real expert! Cheers, D.

Dear expert peeps,

Here's another inevitable follow-up question...

The oil weep clearing job has taken a little longer than expected (what's new?) thanks to one of my exhaust pipes literally falling apart from the collector box. Clearly, it's rotted through from the inside but only became noticeable when disturbed. Hey ho, some miracle welding from a genius welder mate of mine and it'll be ready to go back together next week.

During the intervening period, with no head on the engine, oil is now weeping from the cylinder base gasket area.

Does this mean I now have to remove the block and replace that gasket, or will it seal up again when the head if finally reattached and torqued down?

Ta, D.

Yes indeed. I received a suggestion by PM hence not sharing, sorry.

I was shown a picture of an 'oil pump gaskets set' that had only two of the questioned O-rings therein. The two options shown in the parts catalogue are shown on David Silver's website to be of different sizes, 13.8mm or 15mm. I simply then measured the ones off my bike (15mm).

I'm still unsure as to why there are two sizes, but at least I got the answer I needed to progress.

Cheers,

D.

Thank you!

The inevitable additional question...

Looking at the parts book (see attached photo of oil pump assembly), there are 0-rings numbered 286 & 287 but only one item is shown.

Does that mean both are required or that they're optional or they're model-dependent?

Mine's an early bike (i.e. not an F1 or F2).

Thank you all (again),

D.

Thank you all again.

This forum has always been a refreshing change from the bleating and moaning on other forums that I have since left!

Thanks Mike, will do. I'm hopeful it will still be like a clean sewing machine in there!

Thank you all for your wise council.

Bryanj - the copperised ones are the ones I was thinking of. I'll check out Hondaman too.

I think we can all agree, there's probably no rush to do this as I think we've all now got lots of spare time on our hands!

Stay well everyone.

Can't remember that either, but I  know they leak all from the top if the wrong ones are used, so I guessed they can't be re-used.

No doubt when I actually start the work, some of this will come flooding back!

Thank you Nurse Julie. Maybe using that stuff last time is my problem... not that I can remember what I did/didn't use!

Hello all,

When I rebuilt my 400/4 some years ago, I didn't quite seal it properly so I have oil weeps from most of the major split points (i.e. cylinder head, block base, etc.). They're not bad enough to worry much about, I just wipe it over every time I use it... it's hardly old British bike territory!

However (you know what's coming), this enforced isolation business is a good opportunity to spend time in the garage fixing it.

My question is this:

I would like to buy all the bits I need to do the job IN ONE HIT (especially as some of it will come from David Silver and so I'd just like to pay one lot of postage please)! Is there anything else I need on my shopping list in addition to these items:

- Gasket set
- Oil seals set
- Head bolts (with oil seal washers)
- Hylomar or some such

Thank you, D.
