I'm not sure head pics will help if that's the case, it sounds more like piston trouble to me  

its possible ( looking again at the physical parts) that its had rocket cover leak form one side....could have possibly leaked over and around exhuast manifold....maybe even into it..

Wouldn't explain why oil is also coming up through the inlet into the throttle body  :-/

was it a substantial amount?

[Marks DTM Calib]

Time to take a step back people....

1) The oil control ring is exactly that....a control device. It ensures an even coating of oil on the bore and stops to much getting to the compression rings.

2) 0 compression cant be due to a broken ring....thre are at least three rings on the engine!

3) Do the parafin test on the head.......this will show if the valves are sealing correctly.....it must be done before stripping he head

[JamesV6CDX]

I agree with Mark's suggestions. With the camshafts out, (so valves are all up against their seats) - on a close inspection, are they all seating right? (especailly on the cylinder that's playing up).

If you can't see anything, do as Mark suggests, the paraffin test - it will show if any valves are not sealing in their seats for whatever reason..

Oooooop head already off before Marks suggestion....

[Markie]

pictures aint perfect.....and head is not yet cleaned, oil in throtle body was not that bad....just something i havent seen before...

[Dazzler]

I can't see from the pics but in order to get 0 compression there must be a big hole somewhere :-/ Just like James's LPG head on his Veccy, a lump of valve was missing. I would have thought there should be something quite obvious to see :-/

You Need the head off for Mark's suggestion

Ok, put the plugs back in.

Put the head down (in a tray), valve side up.

Fill each bank of valves with an equal amount of parrafin (as much as you can), and see if the level drops.

If it does, it indicates a poor valve seal... (against the seat)....

[Marks DTM Calib]

Look for the parafin appearing in an inlet or exhaust port.

Im done for tonight, and by the look of my outlook calander i doubt im going to get much more done prior to the weekend  

[Marks DTM Calib]

Looks like number 1 cylinder has been steam cleaned to me......much cleaner than the rest of them both on the head and the block so thats a major head gasket failure.

God that K series block design is bloody awful.....no lateral support between cylinders just drop in liners.......no wonder it has problems.

Get a straight edge on the head....I bet its warped.

And i bet your right, the head gasket looked in resonable condition to me, ie not the original from a 1998 car with 100000miles on it.....

Thats probably its third then......

thats pretty good,but then you probably look after the Rover   those that dont generally get 50-60k

Small update on this.....whereby my powers of observation will be reprimanded by Mr DTM...

All my attention was focused on the head and valves.

Remember 0 compression on no2 and 20% reduced compression on no4. Oil from exhaust manifold on no4.

Last night whilst tidying workshop i just happened to glance at the block which is still inthe car.....

number 4 cylinder has a hole in it   so would that explain oil and obviously low compression.

Now if thats what happens to nomber 4 with low compression what on earth will i uncover on no2 no compression !!

I have an identical block on a hoist currently so sometime / somehow i can create a complete engine from this lot...
