Upgraded Thermostat

Post by Hi-Fi Man » 15 Jul 2017, 05:37

I just thought I would give a follow up to my last post regarding the modified thermostat I fitted a week ago. I have no connection to the seller in the US (logic7amps) but I would urge anyone with a V8 powered BMW to fit one, its a very easy diy job and the difference it makes is quite astonishing. Before the mod, you could spit roast a hog over my engine, even after it had been switched off for an hour and when stuck in traffic for any length of time, the car felt sluggish and the stem seals would start puffing oil, it was clearly running way too hot (as it was designed to do by BMW) but my cooling system was in perfect condition and I had only just fitted a new genuine BMW thermostat and expansion tank and cap. Now, there is none of that, the engine is much cooler running and a lot smoother in heavy traffic and the stem seals show no signs of smoke. The only downside is that it seems to do about 1 mpg less around town but its a 6, who cares about mpg.
Also, while im here, could I please ask people for there opinion on the Elipsoid wheels. I cant make up my mind about them, they are very easy to clean and they seem very strong as I have hit a few pot holes hard and they show no damage. Ive seen plenty of good looking wheels online for about £500/£600 a set but they look like they would fall to pieces at the first sign of a pot hole and I don't want to drop £1500/£2000 on a set of wheels as that money is going towards my new 500bhp heads/cams. Your opinions, good or bad is welcome, thank you.

Not a fan of the elipsoid wheel personally, I have a set of 19" F06 rep wheels for sale that I had on my 650i, also have a full Bilstein B12 suspension setup available as well.

Your wheels do look nice, just looked them up and real ones are £2200 each! which is way over the top for me, what sort of figure are you looking for.

Good info on the stat,
Each to their own when it comes to wheels etc,
but personally I think the mighty six deserves better.

+1 for ditching the elipsoidals - I'm not sure they ever looked good, but certainly 'age' the car. I put a set of cheapo 19s on mine and neve rhad a problem with tyre seating, potholes etc.

A set of cheapo's it is then. I will put the Elipsoids in the shed just in case the cheapo's fall to bits.

Great info on the 'stat. Do you have any links? I'm helping a friend with a smokey 745 at the mo, this might be a cheaper alternative

Glad it may be of some help but if the valve guide stem seals are totally shot, then nothing short of replacement will stop the smoking.
Information and how to buy can be found here. http://www.bmwlogicseven.com/?cat=151" onclick="window.open(this.href);return false;
I also run 5/40 in my engine as opposed to 5/30, its a tad thicker when hot and does not get past the seals so easy and does not and has not caused any harm to my engine.
