Sump plug

You've never bled brakes?

 

nope.

 

I suppose it's a class thing.

 

Heh. "There are only two classes..........."

 

well, I'm not in paid employment, for sure.

 

I can imagine a Scooby would be difficult.
A 997 model Porker is an Up on the Ramp job.

 

The Jeep's had the same plug in cylinder #6 for 108k miles cos I never
could figure out how to change it. Still runs perfectly though.

 

Not a Champion plug then

 

Christ no I'd have thrown it at the dealer to change if it had those.

 

This has just filtered through. You bastard.

Do what?

 

On a similar subject, I replaced my cars cylinder head last week, and a
valve broke as soon as the engine was turned over.

Being as it was tightened up, should I use new bolts? I was thinking of
checking the torque they are tightened to, then doing them up again to
that torque when refitting - they are originally tightened to 60nm, then
90 degrees, then a further 90 degrees.

They are £20ish a set, and I'm a bit short of cash at the moment, so
would like to save some cash if possible.

Swedish oil company, innit.

 

or 180 degrees of course...

Yes, it is a pain in the arse, they are so tight that you think they
will snap at any time on the second 90 degrees, I was using an 18"
breaker bar to get the leverage.
You are right, I should use new bolts, but I'm so pissed at having to
speend more money on it. I will be reusing the head gasket though, they
are £35, and I cannot see a problem reusing it, as it hasnt even had any
fluids in it.

No way would I re-use stretched bolts. What I might do if stuck is find
some 'normal' bolts and stick them in and torque to the nominal book
figure, depending on gut feeling.

 

Agreed. Except for copper head gaskets on some basic strokers - they can
be re-annealed and used again and again. I must have had the head off my
Yamaha Why Bother 100 more than a dozen times to decoke it and never
bought a new head gasket.

ISTR my power-valve, though, had a very complex sandwich-type head
gasket, and that was definitely a use-once-then-throw-away jobbie.

Oh for the days of double-ground and no gasket head joints on some SO
brit singles - or perhaps not.

The 604 'Frigerio' barrel Nordwest used a solid copper head gasket. I
even acquired a slightly thicker 'bespoke' one in an attempt to cure the
cooling system pressurisation issues. This worked for a while longer but
significantly reduced the CR, so I went back to the original spec.


If a composite gasket I would never try to re-use one, even if the motor
has never fired, particularly given the sort of torque involved.

Sounds like the bolts may be designed to stretch and so definitely not
re-usable.

Through studs on bike engines are a different matter so long as the nuts
have never been over-tightened, but it is alarming just how much they
can stretch when you eventually compare them with new items.

My TZR125 had a simple cornflake-type head gasket.

Didn't last long, mind.
