'Orrible Noises

.....coming from the block
Something's bust ,rattling under any sort of revs .It happened 1/2 mile from home so limped back OK .My new neighbor's a mechanic ,I'll get him to have a listen but I fear the worst

mmmm....not sounding good...but it may be nowt!

Exhaust or heat-shield?? I like to keep a positive mind about these things.

maybe just an old socket rattling around in the Vee.
I found a 10mm one when I had my engine out.

I wish ...........
No it's definitely somewhere deeper Can't locate it but it's bad ,really clattering .Not audible on tickover but when the revs rise it's like a hammer drill .

Are you sure its not a loose spark plug? I had that and it sounded awfully nasty.....like big ends.....big relief when it wasnt!!

I remember you saying ,but no they're all fine
I'll whip it down the road to my local MOT guy Monday morning for a listen ,daren't risk a trip over to my main man .

Not asure if this is good or bad news.... I had a similar noise from a SAAB years ago- it turned out to be a broken valve spring- amazingly it didn't drop but it did shed some metal and the compression on that cylinder was never quite as good after the repair. I drove it back like that and had to fit a new guide and valve as a result- get it fixed quick!

It's an Alpine, bound to be something terminal and/or expensive

Never met a bottom end problem that wasnt caused by poor oil pressure - have encountered nasty cam noise thanks to blocked oil jets on rocker arms - thankfully you need only replace the arm and not the cam - doing so can be done in the car if it's a DeLorean where we can remove the back.... very interested to know when you do work it out.

Oil pressure's always been good ,never drops much below half on the gauge anyway .I hope it's something simple 'cause if not it's not getting done this year

First diagnosis from the guy up the road is CRANK
Does this mean engine out or not

yes, engine out to replace the crank.

bigger thought so Longterm project ahead then
If it has to come out then lots of other bits will be attended to ..........

Lee, can you drop the oil pan and have a look see at the crank, perhaps you will see something a-miss, or something in the pan.
