Title: motor been sitting for ten years Post by: waynos on November 08, 2007, 09:00:57 PM hey my 186 finally got running properly but is constantly blowing smoke.kept thinking it was running too rich but is not black smoke.the unfinshed project i bought was sitting in a carport for ten years.my hope is that valve stem oil seals have perished due to lack of oil to top end.hoping i haven't scored the bore on start up still has heaps of compression though.tried wynns stop smoke for half an hour got slightly better.would appreciate any knowledge as i always expect the worst.
thanks heaps waynos :) Title: Re: motor been sitting for ten years Post by: mcl1959 on November 08, 2007, 09:50:26 PM What did you do before starting the motor? Oil burning smoke is usually a blue/grey colour. Good compression means that compression rings are OK, but oil rings may be broken.

Title: Re: motor been sitting for ten years Post by: FB_MAD on November 09, 2007, 02:44:10 PM I worked in a wrecking yard for 2 years in the late 1980's.Some of the motors we fitted had been sitting around in the shed for years and displayed symptoms similar to yours.Most came good after a good run under load ( ie , a good long drive on the road ) and smoke and rough running diminished as well in most cases.
I remember fitting a Gemini motor which had been sitting around for ages.The boss said he remembered it was a good motor so I fitted it. Once fitted I just couldn't get it started no matter what including aerostart.Compression test resulted it all cylinders around 40 to 50 psi.This motor ain't gonna go, it's stuffed. No, it was a good running motor the boss said so we eventually got it going by tow starting.Ran rough as hell at first and quite a bit of smoke. Took it for a 10 KM drive and came back idling and running much better. Gave it to the owner and he brought it back a week later for a "checkup". Compression test all cylinders, 130 to 140 psi and engine running perfect, no smoke. If you are able to, take the car for a bit of a drive and see if the smoke situation improves. Terry.
