Effects of no exhaust stem seals?
Turbo Mini Forums

Hi!

I get a puff of blue smoke if the engie sat at idle for awhile (at lights p.e.) and I acclerate hard... Also on start-up from cold Iget a puff of blue smoke. But not under normal driving & acceleration...

I didn't fit stem sealsto the exhaust valves - could this be the reason? Also the guides are pretty worn, so the intake seals might have only a limited effect.

Could this be related, or is it rather the rings? :)

Engine is a n/a 998 'junk/spare' enginewith a 12G940, so nothing precious or expensive. I'm not worried. Oil consumption is normal, even when you conider how much oil it pisses on the drive way

It's just - I've never ran a engine without exhaust stem seals... :)

Cheers,
Jan

[X] nail here for new monitor

sounds like stem seals the later rover ones are good. but worn guides will make it smoke too. can i ask why you didnt put any on the exhaust valves

Done now needs redoing lol

If the guides are worn then they will give you the smoke. You will be fine if not better without seals on the exhausts particularly on a turbo where the valves get warrm.
