Oily Smell
TZI smells a bit of oil on first start up, Ive checked the breathers (the gauze out the top of the filler is missing) and they are clear and theres no blue smoke. Shes done 90k, do you think it could be old age?
Lots of Motors, mostly semi broken....

At a guess I would say the valve stem seals have hardened, allowing some oil to drain into the cylinders when the engine is stopped; get an assistant to start the car while you watch the exhaust for a puff of smoke.
If this is the case, personally I wouldn't intervene until the car starts smoking on overrun/when you change gear.

It's probably oil Tim

Have you checked the wire gauze mesh under the plastic internal filler neck, where it narrows down?
I think?? your TZI filler tube is the same as a 16v.
To make up a spare top gauze, a pad of coarse wire wool surrounded by chicken wire to hold in place may help.
Ideally the gauze should be in place, as this interrupts the air flow and should attract most of the oil mist present and hopefully return any droplets to the sump.
If possible, (can’t quite remember the tapings on a TZI inlet manifold). Remove a hose/? Or any plug, and probe the lower section of the manifold with stiff electrical cable to see if there is any black sludge. Can build up over the years, especially on short trips.
Regards

I always thought the purpose of the gauze was to catch emulsified (sp?) oil and prevent it from re-entering the oil/breathers? AFAIK no oil is actually supposed to enter it, only the vapours/moisture?
Either way, I've run the valver for about 3 years without as it practically disintergrated. No hint of smoke/smells of oil and plenty of mayo Rocker cover on the other hand....arsehole. Always leaks onto the manifold, must be warped!
Does it smell of oil, oil burning on something hot or oil being mixed with fuel, burnt and being spat out the back end?

A likely source of external oil leakage that may not be apparent when it drips on to the exhaust Manifold is the lower part of the dipstick.
Worth a look before assuming the worse case scenarios!

The lower part of the dipstick is midway down the front of the block (as you look at it). The exhaust manifold is on the back of the head at the top. Am I missing something?kiwi wrote:A likely source of external oil leakage that may not be apparent when it drips on to the exhaust Manifold is the lower part of the dipstick.

I'd guess either rocker cover gasket at the back, a breather blowing vapour onto something hot or one or the O/S driveshaft seal leaking gear oil onto the corner of the downpipe.

I think you've misread Kiwi's post, there's probably a comma missing in a strategic spot Without it, it does read rather different.
