hi wanting the timing marks of a rover 220 turbo has anyone got them and where they should be thanks chris

got the timeing marks but still having this problem

the engine turns over as normal after turning over for about 5 spins it goes slow for a turn or tight as you might describe it then back to normal speed eventually after a few times of that it just about starts but runs a bit rough, if i take the coil leed of it turns over fine as many times as you like.

Stolen from elsewhere on the interweb from MGJohn so all credit goes to him.


First picture:



The above illustration shows the crankshaft pulley index in the 9 O'Clock position. Then, pistons Nos. 1 and 4 will be at 90 degrees BEFORE TOP DEAD CENTRE and pistons Nos. 2 and 3 at 90 degrees AFTER TOP DEAD CENTRE. All four pistons will be at the same level in the cylinder bores. When 'timing' the engine prior to fitting the timing belt, that crankshaft index must be set like this.

Picture 2:



The INLET CAMSHAFT PULLEY (on the left) and EXHAUST CAMSHAFT PULLEY (right) need to be in this position. However, it's not as simple as that because there are TWO slots on the camshaft pulleys- see next pictures - and the correct slot must be selected..

Picture 3:



LHB10028 - EXHAUST PULLEY with its locking bolt removed to show that the slot marked 'EX' must be located over the roll pin.

Picture 4:



Again with bolt removed, INLET PULLEY LHB10029 with the Roll Pin located in the slot marked 'IN'. The roll pin is difficult to see but is in the slot marked "IN" if you look closely.

Picture 5:



This is how they should look with the timing belt in place and the CRANKSHAFT PULLY INDEX still showing the 9 O'Clock position - see Picture 1.

WARNING Before starting that engine, DOUBLE CHECK AGAIN that CRANKSHAFT pulley index is still in the 9 O'Clock position.

Pictures taken of the engine in my 1993 TomCat Turbo.

yes that is exactly how they are but still turns as norml for a few turns then tight for 2 then free again eventually starts but rough running call me on 07854456464 for better description does this sound like timing or something else

[E_T_V]

Have you had the pulleys off? They are easily transposed and the engine struggles to run if they are the wrong way round.

Also are the HT leads on the right way round?

[chris799]

just the rear one needed to change the cam due to it not having a cam sensor on it but used the same pully putting it back again

[E_T_V]

With the roll pin in the correct position?

Sorry if I'm teaching you to suck eggs but the number of people who get the timing wrong is HUGE! so it is worth double checking.

[chris799]

yes everything is as in the picture

[chris799]

just looked and spoted something the left pully is a lhb10028 instead of a 10029 so on my car they are both 10028 could this be the problem ???

[E_T_V]

NASP (Normally Aspirated) Rover T16, both Inlet AND Exhaust camshaft Pulleys carry the same ID number LHB10028.
The early T16 Turbos also used the same LHB10028 Pulleys in the 180ps engines I believe.
Later 197ps turbo engines used LHB10029 for the inlet camshaft.

the engine is out of an s reg coupe i have changed the back pully and it is better but still gets a tight spot but not as much any ideas what else i can do ??
