Reliable repair tutorial Rover K series engine
For the reliable repair of Rover K Series engine, we must observe these measures.
Skimmed for that the block is flat.
The dowels of the top block part
have a height between 10.50 to 11 mm.
Its mission is centring the cylinder head for proper placement, in addition to supplying the oil serves to lubricate the top parts.
The dowels should be of steel never thermos plastic, because
in whatever time the gasket head will be produce the mixture
of oil and coolant.
Never clean the top block with paper, as this can leave
some residue use a rag.
It is very important the issue of the cleaning and especially
in the top block, does not matter if it's metal gasket as
if is of elastomer should not be traces of oil or grease
for proper sealing, it is advisable to clean the top of the
block using alcohol or degreaser and dry completely before
putting on the gasket head.
By joining the two halves of the block there is apply silicone
and verify that this silicone after tightening has not been
introduced into the holes through which pass the
bolts that attach the
cylinder head and block, or any channel through
which oil goes up or down.
After closing the two halves of the block and before harden
removing the excess the silicone with a toothpick.
cylinder head should not exceed 118.30 mm of height, going beyond means weakens
excessively with the consequent risk of breakage. The measure
is valid when is new OEM is 118.95/119.05 mm.
With a cone tool of about 5/8 mm,
we increased the water passages into the cylinder head is a very simple procedure, is simply to remove the burr of surplus assets in excess of the form that already has the water passages, this operation must be to do before the skim.
Cleaning the top of the
cylinder head, must be made in the
same way as that used in the block.
When removing the sealant around the top of the
cylinder head, which makes the seal between the cams, must be done
with utmost care not to produce any deep scratches.
This can be done with a brush, leaf cutter or spatula special
In applying the new sealant to the
cylinder head cover makes
closing the cam, one must be very careful with the amount
of sealant and an excessive amount of sealant, obstruct
the passage of oil that lubricates the cams, producing abnormal
wear on these and aluminium cylinder head.
We'll also seal around the circumference of the spark plug,
if the close is defective were filled in a greater or lesser
extent of oil outside spark plug.
The oil rail is at the bottom of the block and must be
completely clean by observing the cleaning protocol described
for the block.
Due to the squeeze and the temperature it can be cracked
in the aluminium on the outside, if you look at first glance
this should be replaced immediately.
There are two models, most recently for the quality of its alloy provides more rigidity to the structure and reliability, but both are valid.

The liners rover are liners floating and wet before being
placed there is necessary to clean as I have explained above
the dirt that may exist in the block.
Its height should be between 0.09 and 0.11 mm above
the top of the block.
Cleaning should be exhaustive in the seats (support that
has the liner and makes closing the block).
The seat in the block that makes the closing with the liner
also be perfectly clean.
Add a little slow drying cyanoacrylate to the seat liner.
This sealer will make our liners stick perfectly to block and to be slow drying, we have time to put the old gasket and bolts and with the cylinder head skimmed if is possible, do a little torque to settle the liners properly while the superglue dries.
Be careful with the amount of cyanoacrylate, better put
a small amount and spread with a toothpick.
Never hit the liner with a metallic element, because when
put the liner on the block if it is not entirely straight
may snag and be stuck.
If we are to put the pistons back into their liners because
we have retired of the liners must be well oiled by the
When you place the piston rings will always be the correct
position on the cross, separate each about 90 degrees.
If the piston is withdrawn with excessive carbon into the
crown or around the rings, it is advisable clean perfectly.
If you are going to use the same rings and bearings con
rod or crank, mark the cylinder properly and corresponding
Failure to do so can result in a failure, oil consumption
or abnormal wear of parts.
Cylinder Head Bolts
If possible always use new bolts by safety, because when
used the old bolts to having tight and take temperature
the stretching is permanently engraved on them and then
when apply the torque for the press, will not make the proper
closing of the block and cylinder head.
For a perfect squeeze and close, allowing time for the
fire ring gasket to make the support and closed with greater
reliability, use this tightening sequence.
20 Nm +90+90+90+90 degrees.
Thus the stretching of the bolt will be less, because
it is more gradual and not much force is exerted by tightening
Before putting the cylinder head bolts, oil or copper grease applied before tightening bolts and proceed to remove the excess.
This prevents possible damage to the threads of the oil
Do not put fingers or leave oil stains and grease.
Two models are completely reliable if we followed this tutorial
-Ref: LVB 000320 SLP -Elastomer
-Ref: LVB 500190 -Multilayer
If using the gasket (MLS) you must use
the latest rover oil rail.
Since this engine has hydraulic followers is advisable
to use a more viscous oil than 10W/40 and
of course fully synthetic.
Camshaft, Followers and Bearings
Whenever an engine is producing a mixture of oil and coolant
should be replaced all bearings crank, con rod and the axial
and is also recommended to inspect pistons, con rods and
When put back into the engine, we have to clean all parts
with much care, but above all the bearings seats at the
bottom so that the adjustment is perfect and have no dirt
in them, whether on the block or con rod.
The oil should be applied in each and every one of the
con rod and crank bearings, also on all piston pins and
cams seats, for not producing abnormal wear during initial
Do not rotate the crank before they pressed the
cylinder head, because until that this tightening does not occur,
the bearings are ovalized by the lack of pressure from the
bolts, if you turn produce abnormal wear and offset them.
Lubricate the outside follower and housing, thus avoiding
produce scratches on the aluminium cylinder head.
Drain the follower's oil completely before putting it into
the engine if there is mixing of fluids.
Whenever possible, we must replace the thermostat from
88 degrees by another before opening.
If the thermostat has a hole for filling mixing of hot
and cold coolant before it opened, will be placed toward
the cylinder head, never to sump.
Place a fan thermo-contact to acting at 85/90 degrees.
Before put the oil pump on an engine must perform the inspection
of the size spring acting on the wastegate
To proceed to loosen the bolt pump, the pump should be
placed on the engine to avoid damage.
Its size must be between 40/41 mm, If its
length is less need to replace the spring or the pump.
Apply sealant to the nut/bolt before screwing back.
If you disassembled the oil pump, the rotor and the eccentric
should be scratched the least possible.
The rotor has a small notch that indicating their placement,
which should be once you put the pump in its working position
is facing outward.
Observe well the two halves of the interior of the oil
pump, if there is an undermining excessive or wear must
The oil pump with a larger rotor of 11.5 mm is the best one. Ref: LPF 000030
Always 50% antifreeze and replace if possible
every two years.
When an engine has been completely disassembled, to do a simple protocol so that all parts are lubricated before of the start.
Switch off the ramp injectors and proceeds to give the
start for a few seconds and repeat the process 4
or 5 times.
The oil reached all parts and when we proceed to start
the engine and the rpm take 900/1000,
all parts will be properly lubricated.
