Smokin Zed

[biker]

I have noticed lately that my poor little Zed is starting to blow a bit of blue smoke under acceleration. I was hoping that it was fuel but something tells me it is probably oil..

Power is still good and oil pressure has no noticable change except at idle where it seems to drop a bit lower than normal and I can smell oil fumes in the car.

I usually associate blue smoke with either rings or valve seals.

Anyone got an idea on how to eliminate one or the other. Any other suggestions as it seems to be more noticable since I changed the coil to a higher voltage.

Just bringing this topic back to the top

Anyone with any advice???????

I too have this problem. After reading a lot in this forum, as well as others, I am guessing that the non-hardened valve seats have deteriorated from lack of leaded gas use by the previous owner. I guess it could also of course be the rings, but I would be surprised if this was the case since the engine only has 110,000 miles on it.

In either case, I think it is in need of a rebuild or a swap-out. I am not really insterested in building a super performance Z, as it is fun enough to drive in stock form, IMHO.

Oil consumption is pretty high, I need to add about half a quart every 100 miles! I do not really plan on driving it much more until I do something about this problem.

I know several people on this board have sent their engines into companies like Jasper to have them rebuilt, were you happy with the results? How much was the total cost with shipping and everything? I wish I had the time to rebuild it myself and learn a lot along the way, but I just do not have the time at this point . I would much rather have the entire engine rebuilt at this point, rather than just pulling the head and having some headwork done - Rather get it all at once and have a nearly 'like-new' engine to enjoy and treat well from the beginning.

Sorry to hijack your thread biker, just seemed like the right place for my post to be since the problems sound identical.

No problem Andrew

A litre of oil every 100 klicks - whoohoo its got to be going somewhere:D

I won some Fuch oil at the races last year and gave it a go. Seemed pretty good as pressure was up and thickness stayed for a lot longer.

However, a mate has said that he has been noticing the smoke for some time following me round the track :cheeky: but can't remember when he first noticed it.
