Re: What Oil do you Use in your 6'er

Threads like these can always get a bit messy!

This article carries a pretty strong warning not to use VR1 other than in a race car...

Re: What Oil do you Use in your 6'er

All of the ones you list will be ok for the conditions the car you will be use in, but I'd be inclined to stick to the manufacturer's recommended of 15W40.

Re: Brake pedal randomly goes to the floor

All else staying the same, the effect of an increase in bore will be that you need to press the brake pedal harder to achieve the same braking pressure in the lines, but pedal travel will bit less. You are exactly right there, and that is the effect I was going after anyway. I much prefer braking b...

I installed the same 750 master with the upgraded calipers, no extra pressure needed.
The car always had pretty good brakes, but the upgrade when your on the track really
makes deeper braking possible.
Ok, but it's altogether different if you install different calipers at the same time.

Re: Brake pedal randomly goes to the floor

I'm glad you've had a good outcome. Any circumstances in which the brakes aren't functioning properly is always disconcerting to say the least!! I'm intrigued that you feel that fitting a bigger bore MC is an 'upgrade'. How so? Just in terms of the bore diameter? All else staying the same, the effec...

Would the compressor from an E34 of the same era be any good? Were the E34s using R134a all along?

Re: Brake pedal randomly goes to the floor

If one of the calipers is dragging slightly due to a sticking master cylinder the fluid will heat up in that circuit and can release into the system usually when bringing the car to a stop causing a super soft brake pedal If the master cylinder piston gets itself stuck towards the end of its normal...

Re: Changing auto box oil - what have I done wrong?

The drain from the torque converter is a function of time, as the fluid gets to transit through valves, pump, control tubes and channels, etc. on its way back to the pan. The scheme of a hot, engine running level check goes back to the 1940's and 50's first hydromatics, torque flytes, and ford o ma...

Re: Changing auto box oil - what have I done wrong?

A running engine has fluid filling the torque converter, with a non-running engine, the torque converter drains down to about half of total volume which adds to the level in the sump/pan. This volume is a large percentage of the total fluid capacity of the transmission unlike an engine that has a r...

Re: Changing auto box oil - what have I done wrong?

Could the original fill that you drained have been overfilled so that you are chasing a ghost? DON'T run it to get more out of the box. Rely on the proper dipstick reading technique. The original drain down produced over 5 litres of fluid and I replaced with a like amount. But second time round it ...

Re: e24 OEM First Aid Kit - Brand New

I find it interesting that your first aid kit has an image of 6 Series on the front. As far as I was aware the same kit was installed on quite a number of different models from around the 80s, but clearly yours is very specific to 6ers. Right now there are a couple of the type I have in my car ('88 ...

Re: Seat back latches

Sounds like you need to remove the seat backs to get at the de-latching cable. Not sure whether it's true of all seat versions, but mine have two screws at the base of the back cover and then the cover should slide upwards (having first removed both release levers and their surrounds) - but might be...

Re: Strong exhaust fumes smell

Presumably a cat equipped car has a lambda sensor (whereas non-cat cars of the era, like my own, did not)?

That's where I would first be looking ie is the lambda sensor still connected and/or in good working order. Otherwise I guess I might be thinking it could be a faulty airflow meter.

Yours was designed and tuned to run a catalytic converter, the Euro models weren't.
Clearly that's true, but does that also imply that the ecu mapping is different to suit both versions? And if so, can the ecu be re-mapped?

If it is grossly overfilled, there is the opportunity for the rotating parts to cause foaming of the fluid in the sump. This foam will prevent proper pressures to build as well has having air which has no lubricating or cooling properties enter the ant farm of passages in the transmission, possibly...

It draws air from in the cabin to measure the temperature. It's the thermostat that controls the heat/AC. That thermostat is a small box mounted on the under dash panel on the left side. Thanks.

Clearly this is some kind of vacuum pipe, but what is it it's purpose? Heater related? Interesting the Real OEM depiction of where this pipe is attached to the manifold shows it as capped off, but mine has always had the pipe. It came to my attention because I found that it had become detached. Coul...

Re: Strong exhaust fumes smell

You found it. That lack of a catalytic converter is the cause. Partially burned hydrocarbons because there's no catalyst to complete the combustion. But many/most 6ers supplied into the European market didn't have a cat, but I would never have said I've found exhaust smells to be especially noticea...

Re: Changing auto box oil - what have I done wrong?

Just to conclude, I re-filled the box and set the level with the engine running, although technically the gearbox fluid would still be cold so I needed to take that into account. It took around 4.5 litres so I'm reasonably happy with that. Just one last question in case anyone can provide an answer ...
