MG MGB GT V8 Factory Originals Technical - Which timing cover?

I have recently bought a Range Rover engine fitted with the standard 3.5 EFi front timing cover. I know I need the shorter P6 water pump, cranl pulley etc but do I also need to change to the SD1 timing cover?

Yes. See www.v8tuner.co.uk front timing cover new for 199.95.

The SD1 timing cover is fine, just get a new oil pump base with remote filter and cooler. the P5 short nose pump (std MGBGTV8) fits.

Thanks for your help

So what is the difference between the Range Rover and SD1 covers?

I think the earlier Rangie covers were the same as SD1 up until about 1994 ish.

Thanks Mark

The engine I have just bought is a rebuilt 3.9. I bought it from a guy who had it in his Range Rover for only a few thousand miles before lots of other things went wrong with it, think it failed it's MOT too. He decided to brake up the car so I bought the engine. Under the rockers and the inlet gasket is still bright and shiny, you could eat your dinner of it! Basically it has just been run in. It was an exchange engine from V8 Developments fitted with a high torque cam. The guy exchanged his onld 3.5 for it, so when he got the new engine he fitted up his original 3.5 rocker covers, sumop, timing cover etc.

He was using a dual point mallory dizzy which has the SD1 drive gear on it. The 3.5 was an EFi engine so was late 80's. Does that mean the cover is the same as the SD1?

Sorry to keep asking questions but I'm pretty new to the V8 so havn't got my head round all the production differences yet! I've tried looking for pictures on the web to see if I can see any difference but obviously this is pretty difficult cos they're hidden behind radiators when they're in the car!

I don't want to go buying an SD1 cover only to find it's the same as the one I've already got.

My engine is in bits at the moment due to a 4.6 upgrade. The timing cover is off so if you like I could send a few pics.
When I first fitted my 4.0L (2000 discovery engine)
I used a second hand SD1 timing cover.
I experienced big problems with low oil pressure and noticed that the oil pump housing showed signs of wear.
As a last resort I bought a new cover from real steel which fixed the problem. Very good pressure ever since.

If I can help with anything else let me know. Engine is out at the moment so good for body pics if you need any.

The Range water pump is not the same. The oil pump is in the casing, if it's not in good condition, it does not have there oil press.

If you could send me a couple of pics that would be great, thanks!

I hope I can keep the cover because it also had new oil pump gears and seals fitted.

Thanks for the offer of some body pics, I'll be making a start on the engine / tunnel mods after Xmas so I may well take you up on your offer.

Hope the upgrade is going well, I think the 3.9 will do me for starters, twice the power I was used to will be plenty!

Hi Paul,
Noticed that your engine originally came from V8 Developments. My original 1973 original GTV8 3.5 was also swapped for a 3.9 from these guys.
They are top notch on the Rover V8 and very friendly to deal with. My 3.9 was dyno tested before I pickked it up - just over 200bhp.
If you have any queries on your engine then speak to Ray Webb (owner) or Shaun at the Company.
No financial interest from me just a very satisfied customer.
They also do a lot of TVR stuff - checkout Pistonheads site.

Good Luck
