After my disappointing performance on the rolling road the other Sat, I had it tuned, and it turns out the vacuum/advance mechanism was not engaged in the dissy base plate:shock:Should be a bit better now, butI wonder by how much.......

Richard stop making funny mouse like noises you are frightning an already frightened man......imagine the chains snapping in a traffic jam.......I am going to start taking Aspirin next time I drive about in the Stag.

Sukh.

P.s an aspirin a day keeps Stag paranoia away...

I am just surprised that it runs like that. I had a 1.6 Petrol cavalier that at 140k slipped the cambelt by one tooth. The engine ran like a pig and then when I eventually stopped in a safe place - off the motorway it wouldn't restart. Fixed the cambelt and tensionerand it ran many more miles

re chains snapping,the reason - rightly or wrongly - that I don't use German chains is that I heard they don't rattle like a tin of marbles before they do snap. I like that built in and very audible safety factor letting me know that piston / valve contact is going to happen soon.

You should try freebasing Daynurse for that extra carefree experience

Thats funny,LOL Daynurse,can you recommend the correct dosage?

Sukhis engine seems much better now with the new timing chains so the timing chain problems probably affected the results, but there is also a lack of ignitionadvance (see my other post) which may also be contributing, although it seems to pull like a train now and revs freely . We will have to see what we now need to do if anything.

Russ checked my timing for me and that was 2 degrees out @ idle and that has made a noticeable difference.

Good idea:dude::dude::dude:

Would make a good comparison wouldn't it?

Waht do you reckon Stag Andy, can you swing it?

I can try but we already know the average output of a standard stag,i cant promise anything but i can have a word.

Sukhi,

If you go for a re-run let me know.....I'd love to see what mine is now the carbs are sorted cos it feels like a different car!

Do you have any rolling road figures yet? I see that the Stagwas offered another rolling road run at Enginuity, has it been there yet, if not can you post the results on here when it has been on the rolling road.

Hi guys,

I can confirm that a Stag runs very badly with chain problems. I stopped on just off the A14 - one of my 'favourite' roads after the car's engine note changed at about 60mph. Power just faded away and the car came to a halt on a roundabout. Couldn't get it to start; turning over on the starter motor seemed very slow.

I was on my way to Clive Tate near Evesham to have a ZF Auto box fitted but had to complete my journey on a recovery vehicle.

Clove took off the oil filler cover and saw just a sprocket, no chain!

After stripping he found that the RH chain had come apart at a joiner - I haven't seen it yet but assume that it's rather like a bike chain. Clive also told me that the LH chain had slipped a tooth - stretching ?

I'll try to find out whether the chain was nominally English or German. At the moment I'm assuming English as there may have been some stretch.

I'll report findings later

Hi Peter,

good luck with that - you were lucky that there was no real damage.

Bad news Peter

Wager that if there is no chain then the valves and pistons will have become intimate.

Onto stretching chains

A while back I fitted a set of new chains and sprockets, not many miles later I had reason to remove them but on reassembly I could not get one of the chains to refit onto Cam sprocket correctly. Bought a new pair of "non German" chains from HRS (as was then) and they fitted a treat. I came to the conclusion that even though the car had done less than 10k miles the chains had stretched badly.

I would be very hesitant fitting such a highly stressed componant with a bike chain type joiner .. eek

Good luck with your engine

I understand that there are some modern BMW engines that use chains of the same length as one of the Stag chains (108 or 106 links - not sure which) and they use link joiners.
