engine trouble

[jozzer]

My H reg Fiesta ran out of oil my fault for not putting the oil cap on tight enough.Anyway the man from the RAC put some in and we were able to get home just about.I filled the oil up at home but now the engine is making a terrible knocking sound.Is there any chance it could be saved my poor old Fiesta?

sounds like the camshaft has gone, being the highest point of the engine, the overhead cam runs out of oil first. unfortunately this will need to be replaced.

you can buy one second hand or a recon one

cazzz... you never cease to amaze me!

I know, Im a sad git :D

[sara3]

you're so not :o)

probably the big end shells that have gone, when starved of oil these are designed to take the hit first before the big ends, wouldnt think its economical to fix given what the car is worth.
this isnt an overhead cam engine, it will probably be the old pushrod engine therefore the camshaft is not located at the top of the engine, the rocker shaft is, im presuming it is he old 1.1 hcs engine???

[cazzz1975]

the overhead valves were around from 1989, if the knocking comes from the top of the engine it is the cam, if the knocking is from the sump its the big ends, considering the big end get a lot more oil, the first casualty will be from the top of the engine

cazz the overhead valve engines are still around today, they are fitted in ford kaa's,

If the engine has NO oil the big end shells will go first, and the likelihood is that it is the 1.1hcs OVERHEAD VALVE engine in which case the camshaft is located in the block not the cylinder head. If your theory was correct the rocker shaft would seize up which obviously hasnt happened as its still running. IF it is a 1.4 CVH engine your theory may be correct but not on a 1.1 HCS engine. Given the fact that this is a 90/91 H plate then the likelihod is its the more popular 1.1 engine.

"If the engine has NO oil the big end shells will go first,

the rocker shaft shells or the cam shaft shells are more likely to go before the big end shells

and the likelihood is that it is the 1.1hcs OVERHEAD VALVE engine in which case the camshaft is located in the block not the cylinder head. If your theory was correct the rocker shaft would seize up

the rockers can wear without seizing

IF it is a 1.4 CVH engine your theory may be correct but not on a 1.1 HCS engine. Given the fact that this is a 90/91 H plate then the likelihod is its the more popular 1.1 engine.

possibly the small end shells could go but definately more likely than the big end shells as they are on the crankshaft

ok cazz we will agree to disagree, youll need to text the person your asking for the info quicker as it takes some time for you post an answer

[cazzz1975]

well I have better things to do than spend every waking hour checking for your patronising replies. Im hoping you are not a mechanic..
