Bless 'em.

Still - could be worse. They normally call it a "wrist pin", ffs.

My Volvo 740 did 230,000 miles without an oil or filter change. I
eventually scrapped it because of rust. It had 120,000 on the clock when I
bought it and was 15 years old. I was trying to see if I could kill it but
it won. My other Volvos were much better treated, that one was a test bed
;-)

And I just noticed they think the head pivots on it. FFS indeed.

How much you betting on that?

A couple of years back, I went to a shot-blasters on a local farm business-
unit site. Drove up the lane. Dropped off the stuff. Very brief chat. Drove
out. Ooops. Can't. Lane's blocked. Completely. No way round. Some ****'s
just fly-tipped COMPLETELY blocking the lane - in the FIVE MINUTES since I
drove up there!

I swear some of the scrotes out there actually put more effort into fly-
tipping than it would take to get shot of it legitimately.

Calm down, dear, it's only a 'merkin.

Incidentally, I have a wrist pin. It's in my wrist and is actually a screw.

Yes there is, you're wasting your money. Few if any
engines fail due to a lack of frequent enough oil changes.

My local council have just decided to charge £20 to pick up kerbside rubbish
that isnt put in the bucket, which they have also decided to empty once a
fortnight, instead of every week. I pay the *******s £2700 in tax a year to
do their job. Merkins have it easy.

Takes deep breath, lights up a fag ;-), from a packet of twenty that costs a
fiver, swigs a beer that costs £2.90 a pint, and replies on a 1meg BB
connection that costs £24 a month. :-)

My Golf has done 30 years with only a couple of oil and filter changes.

The engine is still going fine.
