full gasket set with some odd parts?

[nrg19uk]

i purchased a full gasket which seems to have loads of little odd bits any ideas?

[GTMaster]

The two round ones are valve stem seals. I think there's only two in the kit for the induction valves. The plastic cylinder i don't know of, i think there was one in mine can't remember, but i don't think it's listed in my service manual. I did however do a foolish thing since my kit had two flat red coloured round washers and i mistakenly thought they were the valve stem seals (to this day i don't know why since i've changed quite a few valve stem seals), later finding out they go under the washer and nut on the valve cover

i thought as much but they dont fit over the valve stems.
i have two of the black ones and 8 of the red ones

The Red and Black are different sizes they are a tight fit. Never seen the yellow tube in the kit , but maybe you put it over the the end of the valve to slip the valve stem oil seal over the indent for the collets?

[nrg19uk]

The tube bit makes sense but the biggest seal is about 15mm dia and my valve steams are about 20 mm dia, when I stripped the engine I had small rubber o-rings that had gone hard so I replaced like for like so too speak out of the kit. Unless the kit comes with various diffrent one because of changes from year to year?

I took the rocker assembly apart last night and both the end oil ways are blocked solid with crap so I had to soak the tube give them a poke and blow all the rubbish out with a airline. Solid hard stuff came out so I'm gonna strip the whole engine and give it all a clean

Sounds as if its a bit gunged up Neil, If you get stuck with the valve stem oil seals you should be able to pick them up at an Engine recon' shop, in my gasket set there was only 2 red ones for the inlet valves but no way would they fit over the valve stem, ended up putting the old ones back on

ive been looking into this a bit and it seems the aircooled has rubber orings and the bis has oil seals,

but depending on the quality and year of your engine this may have changed.

it would be intresting to know from others what model, year, oil seals they have also the engine class which is stamped on the pistons a/b/c.


another problem i have is the timing chain seems very slack and does not have the oil flingers is this the bis timing chain? or just worn ?

[Pete126]

Yes thats the bis timing chain without the flingers

[nrg19uk]

Is there any diffrence apart from the flingers? Size of cogs?

[Pete126]

The timing chain on the bis and air-cooled are not the same, the teeth and the timing gears are a different pitch ideally your air-cooled should have the correct chain and gears because not only do the little oil flinger's splash the oil but they also tighten the chain, which keeps the timing constant and reduces timing chain noise. 

[nrg19uk]

I thought as much!!  another item to be ordered.

  That Could explain why my timing was all over the place, ive just noticed that the piece of metal between the two cogs has worn away in places.

Thanks for your help pete
