Re: Front crank oil seal.

I've found a spare assembly from an early 3.9 engine - which I assume has the same diameter as my SD1 EFI? It is worn too where the seal rubs, but I've measured the unworn bit at 48.6mm, using digital callipers. (only have a 1" micrometer) Be very grateful if one of you proper engineers could confir...

Re: Front crank oil seal.

Thing is, I don't think I can measure the pulley assembly on the car. So it would mean disabling the car by removing it, measuring, sending off for the sleeve etc. Rather than a day's job for the lot, if I had it before starting.

Re: Mumford linkage.

Happily the engine is running sweet now after years of grief. The problem would only happen on track and not on rolling road! out of 6 different tuners only one diagnosed the problem to be faulty wiring done by the original installers of the EFI system It has cost a fortune to sort out. Very annoyi...

Re: Front crank oil seal.

I was hoping there was perhaps an RV8 engine parts supplier who stocked them, rather than relying on my measurements. :D

Re: Front crank oil seal.

I've searched for my spare pulley without success. So the sleeve idea looks the way forward, since it looks easy to fit. Anyone got a part number or size or whatever, and where to buy retail? Engine is a RV8 3.5 EFI in an SD1.

Re: Front crank oil seal.

I ended up with Corteco - made in Germany. Twin lips and directional. Not fitted yet as I haven't found the spare unworn pulley body I bought ages ago. :D

Re: Time to start wiring the car!

Yup - you can loop the +12v power feed from 30 to 85. Although you might want to use a different +12v supply. Like say one switched by the ignition, with the main power direct from the battery, via a fuse. It may help the think of a relay as two separate devices. A switch (contacts) and the means to...

Re: Time to start wiring the car!

When being triggered by MS, the connections to a relay would be:- +12v Power to 30/51 and 85 Load to 87 Ground trigger from MS to 86 I dunno how happy you are with computers, but a 2D CAD prog like the free version of DraftSight makes drawing so much easier. Once you've drawn a relay (or found a sui...

Re: Time to start wiring the car!

Not looked through them all - but one thing stands out. You're using an MS3? That supplies a ground for the fuel pump relay, not a switched 'live'. As do pretty well all of the MS outputs. I'll have a better look at them on a decent size monitor. I'd not be able to comment on anything which is race ...

Re: Single terminal oil pressure switch for Rover SD1 V8?

The three terminal switch doesn't seem to be the most reliable device, judging by posts on the SD1 forum. When injection arrived, the fuel pump cut-off became an inertia switch. (The purpose is to prevent fuel spilling in an accident - not to protect the engine) So it made sense to change to the sam...

Re: Tweaking stepper motor megasquirt

My guess would be:-

1. Set the throttle stop so the butterfly is just cracking open. (0.004", 0.1mm)
2. With the stepper motor close, set the idle sped to 600rpm with the bypass screw. (Best to use the Tuner Studio tach for this)
3. Set the required idle speed with Tuner Studio.

Re: 4.0l Thor v8 oil leak

I'd first check the rocker cover gaskets. A leak there can find its way into the valley. And they're the easiest to check.

I use ImgBB. But others are similar. Upload your pic to it, then set 'embed code' to 'BBcode full'. Copy and paste that link here.

Re: Lambda LSU4.2 or 4.9?

It was the MS forum that told me not to use Innovate. :D I didn't have an opinion on them before getting MS. Favourite these days seems to be Spartan.
