220 coupe

[kib510]

My 220 coupe (non turbo) has no compression on No1 cylinder. Its done 112,000 miles since registered in 95. Could be a sticking valve according to the nice man from the AA. Any suggestions?

Could be but i've not heared of it before its not a common problem. More likley to be head gasket whats the oil/water like.

Try posting on rovertech.net loads of really helpful people over there.

Rare for a t16 to let go of the head gasket without any overheating going on.

What are the symptoms? Using oil? Smoking or steaming from exhaust? Mayo in oil or water? Lumpy running? Low/no power?

Going back some time now (about 13 years!) I had a less than 1 year old 8k on the clock Rover 220 Coupe, which whilst in my ownership had a burnt valve on one of the cylinders, so no compression.



Rover contributed towards the cost of the repair, although not the full amount. At the time one of their chaps said that some of the early cars (mine was a L-reg) had a head for leaded petrol, when everything was just being run on unleaded. Not sure if that’s true, or a cause.



Could be a burnt valve. Seem to remember it wasn’t cheap..!

Now, I'm not the be-all-and-end-all of Rover wisdom but I have NEVER heard that before and it sounds like a bunch of danglies to me.

Main reason I think it's danglies is that the T16 engine was designed to run with a catalytic converter which will be killed stone dead if used with leaded petrol.

So I think yer man there was having you on.

The early 420's had the M16 which didn't require a cat but that was without doubt before L reg. Latest of the lates would have been a K I reckon.

The 220 GTI had the M16 to well the H/J plate ones anyway. I think Jonny5 had one.

Oh aye, forgot about that one.

And yes, Jonny had that when I first got my 214... back when this 'ere were all fields, lad

If compression on No.2 is less than 80% of 3 and 4, then suspect head gasket. If it's No.1 only, I would suspect a cracked compression ring or a holed piston. Go to www.rovertech.net  for more advice (I'm on there, a 220 Tomcat owner, as 'Aquila').

Well.... sussed out the problem!! Removed the head and found a bloody great big hole in one of the exhaust valves! no wonder there was no compression.

If one has gone, is it likely to happen to the other 15, or can i get away with just replacing the one valve?
