Anyway, I have done the repair in the last couple of days,Removed sump, oil filter, droped oil pick up, removed water pump fan, harminic balancer and replaced cover complete with new oil pump gears !

In the process the engine was completely drained of oil, when I finished the job toninght (with the help of Taff ) we filled with coolant and oil and started her up !

It had a noise like the tappets had no oil ??? Can any one tell me if I need to prime the oil pump or any thing that im required to to to complete the job ?

Cheers
and thanks in advance !

If similar to pre 95 V8....Yes, yes. You must pack the pump with petrolium jelly (or similar) and pull the dizzy and is a good idea to make an adapter and spin pump with a cordless low torque drill till it gets firm. . Well at least pack the pump and kill coil till oil light goes out.
I hope it did not run for long? If so it may have sh-t the pump and con rod bearings

I run for about 5 mins and the noise did not apear to be getting any better ?
Could the oil pump not be working ? The gears were spinning freely when i fitted the cover ?

Thans for the advice "Rangier Rover" are you saying I have to remove the cover again ??? is there any way to prime it without removing the cover

I cant recall pump set up on p 38 but if similar to pre 95 pump is on end of dizzy drive. Remove end cap and pack pump. Is good idea to prime any pump after overhall.

It's a totally different type of pump. It's driven from the nose of the crankshaft and it's inside the timing cover. To pack it would entail removing the sump, the timing cover, and all the ancillaries. YOu can't drive it with an eectric drill

Jez, you say you ran it for 5 mins. Did the oil pressure light go out? I assume it did or else you may have damaged the engine.

If it didn't, you could try unscrewing the top oil line and injecting oil down into the pump.

If you want to spin the engine over without it starting, do NOT remove the spark plug leads - that will damage the electronics. Disconnect the connector to the coil pack.

Thanks Ron..for picking up on this one...What a worry. If it were mine, Id have the sump off and be looking. Injecting oil into galery sounds good though.

OK, I ran it for 5 mins and the Oil light was not iluminated ?!?!? But When I replaced the cover, It had a new presure switch fitted that had a different style of plug on it ........... My presure switch had a different thread so I made an adaptor to fit the wire on and rang rovacraft and they told me that would be fine ?? So im not 100% sure its OK but did not run it any longer incase !

I will try oil down the pipe and check again !

Cheers
