Your help/advice please


Recommended Posts

The guy who looks after my car is currently away and so I am hoping that one of you might be able to give me some idea as to what might have happened so that I can give him the 'bad' news when he returns.

I was returning from a shortish blat when my car lost all power and just coasted to a stop. There was no associated 'bang' or any other indications that this was going to happen. The engine 'turned over' when trying to restart but did not 'fire up'. After a couple of attempts I tried pumping the accelerator and was able to get her to start but she sounded v sick, a cross between a bad case of timing out and a badly blown exhaust, and as soon as I took my foot of the accelerator or tried to move forward in gear, the engine just expired again. I tried this a couple of times and then gave up.

Luckily fairly close to home and SWMBO came and towed me home!

I fear the worse, so please be forthcoming as to what the problem might be. I am told that if the cam belt had broken I would not have been able to turn the engine over.

Thanks.

PS The car/engine is a 2005 Roadsport K Series 1800VVC - as original, no upgrades(yet).

could be fuel pump. Can you hear it running when you first turn on the ignition? If you have an impact switch, this may have been tripped, possibly but not necessarily if you went over a harsh bump. I'm not sure where it would be mounted, maybe on the bulkhead in the engine bay but its black and has a rubber top. impact switch Press this down firmly and you should hear a click as it resets. Failing that check the fuel pump fuse which is notorious for failing for no apparent reason. See recent thread on the subject but, basically replace with 15 or 20Amp rated fuse.

It won't be anything too serious, just needs sorting. If your cambelt had gone it probably wouldn't turn over on the starter and it certainly wouldn't try and run, however badly.

If you're anywhere near Guildford I could come out and have a look if it would help.

Thank you for the response Paul and I am the more knowledgeable for it - not hard when it comes to me and things mechanical!

Somewhere for me to start either this evening or in the morning. Hopefully John, my mechanic, will be on the case soon, but useful for me not to look too ignorant.

I will keep you posted.

PS Thanks for the offer of help and whilst Brighton not too far from Guildford, the seaside is not necessarily the best place to be with this weather we are currently having!

did you have a missfire before hand?...Sounds like a Coil pack has packed up and has dropped down to running on 2 Cylinders there are two coil packs plugged into the head one per pair of cylinders if one goes it sounds like a badly blown exhaust and lumpy...Coil packs do pack up a lot on a K Series..if it is, just make sure you get the correct coil pack VVC ones have red tabs on them and Red on the ends of the rubber casing..all black ones are the wrong ones as they are shorter and only for non VVC...

 

Frightening when it happens as you think something major has gone wrong with the Engine!!.

I would make sure all Engine external components are checked.. 160 VVC is a strong well specced engine, yours being 2005 is probably the 160 Trophy spec too which has the higher spec Trophy pistons and larger valves in the head.... Please do report back as having owned a 160 VVC for 3 years I'm intrigued and curious to know what it is. *cool*

Hi guys - in particular StEVEN - and sorry for the delay in coming back to you.

 

A synopsis of what the problem was follows (to those that might be interested) and I am pleased to say we are 'on track (well the road) again.

 

It turned out that there was no compression in cylinder no 4 and the reason was this - and please bare with me as I am only now just about understanding the basic workings of the Rover VVC:

The camshaft for C4 is hollow to allow the passage for the camshaft to C2 and is only pressed into the drive boss. What had happened was that the camshaft had turned(!) in the boss and as a result the lobes on the camshaft for C4 were no longer at a 90' angle to C2 - in fact they were in line!

 

Bottom end ok but needed some work and a new camshaft to the top end.

 

Not sure what caused the problem, but has been suggested that over revving the engine might have caused it. Certainly was not doing so at the time it happened and whilst conscious that on a few occassions the rev limiter might have come into play, I thought that was what it was there for!?

 

Anyway, everything seems ok now and thanks to Dave Andrews (Oily) for his chat with my guy down here.

 

Looks as if it is going to be a nice weekend down here in the South, so feel a couple of blats coming on.

 

Hope you all have a good one.

Sounds odd that cam/lobes had turned 😳

 

The inlet cam is actually in two parts. The exhaust cam is one piece. There is a short cam belt at the rear of the engine that drives the inlet cam for cylinders 3 and 4.

 

Glad to hear it has been sorted.

The part of the cam with the lobes is only a press fit into the part that drives it, if the interference is not spot on then under the affects of duress and temperature the cam can turn in the end boss, it's a common problem which is why I was able to diagnose it quickly over the 'phone.

 

I have seen a number of engines rebuilt without the builders realising the mechanism had slipped with the result that after replacing bent valves and rebuilding, they immediately bent again on startup.

 

Something to watch for.

That's sounds really carp! Is it literally just a press fit? Surely a more sensible option would have been splined or male/female lobes to join it. What was the reason for making it in 2 parts anyway. Anyone know?
