Sump plug

The oil leak thread up there ^ made me think of drain washers. I reuse
mine all the time, but I wonder... has anyone ever heard of one
leaking?

 

When I bought the LE Velocette it was dripping slowly, the fibre washer
was rock hard. A new fibre washer fixed it at a cost of almost bugger all.
Why take the risk when a new washer costs pennies and takes seconds to fit ?

 

For sump plugs? No effing way.

 

Not really necessary, but equally don't use the same one for decades.

 

I have, once. Camchain tensioner mounting bolt on my GT750. Low torque,
set the wrench to that low torque (about 8 ft/lbs IIRC) and it stripped.
Bastard thing.

 

the bloke that wrote the manual, you mean?

 

K100 16V cam cap bolts. Fucking cunting things, especially after home
servicing by people who don't use a torque wrench....

I had a box of Trueserts ready on the bench.

And of course I was under orders after the BBC R80 debacle, I had to TORQUE
every sump plug and drop a blob of silver paint on the join.

The one that freaks me a bit sometimes is bleed nipples. A bit of corrosion
can make sealing them feel too damn tight.

Me neither.

<shuts the **** up>

 

Ditto, through believing the Book of Lies. A fecking mistprint had a
rogue '1' in front of a '7' for a 6mm camcover torque setting.

 

I had that on the torque settings for the cam caps, same bike, same
manual. It was in Metric and looked odd, so I did a conversion and
discovered it was out by a factor of 10. Lucky I'd double checked
before applying a spanner, but something like 85ft/lbs looked damned
odd for a cam cap bolt.

 

Nope, never. I've snapped a bolt and streched another one by blindly
believing the torque wrench though

I did cross thread a spark plug once :/ [1]

Fucker was down in amongst some FI pipework.

That was a head off and helicoil job

Whats the rubber tube trick?

You put a longish tight fitting rubber tube over the ceramic and wind
the plug in by hand. Especially useful on engines that have plugs
buried deep inside the cylinder head where fingers won't reach.

It stops plugs getting cross threaded as easily as just blindly relying
on a socket to wind it in all the way. With the rubber tube your
fingers will feel if it cross threads cos it will stop and the tube
gets kinked up.

 

Amazing. Iv never had an engine that the plugs were that deep, so would
never have thought.

I always finger screw plugs in however until they need nipping up.

Golf gti 16v - not good....

 

Yes. eventually they die even with annealing.

My car started dripping oil afther the fisrt oul change in my
possession, I think. I've tried new washers and even a new bolt - all
to no avail. As far as I can tell the surface is OK and I don't think
I cross-threaded it or anything. I torqued it up correctly and
everything [1]. I eventually started using soft silicone that I bought
for diff drain plugs on another vehicle. That fixed it.

[1] except last time - I took the torque reading out of a workshop
manual for an older model rather than the car's own user handbook - I
thought it seemed a bit excessive at the time. It was only when I
stumbled upon the correct value whil looking for something else that I
realized my mistake. Luckily it doesn't seem to have done any damage.

 

Never, ever.

I sometimes find myself gritting my teeth just doing a bolt up to the
correct torque - head studs and fromt brake caliper bolts often do up
tighter than most normal bolts of a similar size & thread.

 

*cough*

The guy who bought an 8V K100RS off me claimed that I'd overtightened
one of the cam cover bolts. Of course, he could have broken it himself
but I do have memories of one feeling 'not quite right'.

Undoing them always has me wincing as I wind up the pressure, ever
since I had at least one shear off my old XS750.

Nowadays I generally use Plusgas first and fit an old small socket
over the top - just big enough to bear on the hex part - and give it a
few taps with a hammer to help crack any seal that might have
developed. I do them up with minimum force - just enough to seal with
the lever pulled hard, then tighten a tweak more.

I hate undoing bleed nipples.

 

On SOBs, I apply heat as a matter of course before I wave a spanner
anywhere near the bastard things.

 

I don't even know what one is. Well, I've seen a bleeding nipple[1],
but I don't think that's what you meant.

I'm not even sure this thread is written in English - I haven't
understood a word of it.
