OIL LEAKING FROM EXHAUST/SMOKING HEAVILY

Post by pablo66 » Wed Dec 04, 2019 9:50 pm



Hello
I recently purchased a 1976 GL 1000 LTD with 28,000 miles on the clock .The bike had sat for maybe 3-5 years ,I re-built the carbs using Randaaks carb kits ,carb # 4 the gas in the bowl had turned to a hard gooey stuff but I was able to dissolve it with carb cleaner and made sure all jets & passageways were thorughly cleaned on all four carbs , I changed belts ,plugs ,points & condenser,checked valve clearance % ignition timing , I drained the tank of old gas ,replaced the fuel filter .The bike is on a stand and therefore not leaning to any side ,the bike starts easily with choke on ,my garage is not heated so temp usually around 5 c (33 f) ,once warmed up I can close the choke and it idles smoothely @ 1100 rpm & I can rev the engine and it feels like it's firing on all four .The problem is it's smoking like a freight train out the right exhaust and even after letting it run for 15 minutes the smoking does not clear-up but stays fairly constant and oil will start dripping out the connection between the header pipe and exhaust .In my internet search for a cause I found this thread "Lastwachter » Thu Jun 19, 2014 9:58 am" in "OIL LEAKING FROM EXHAUST"
on this website which describes exactly the issues with my bike ,there was alot of info on possible causes and solutions but never a definite answer as to what caused the problem as it came to an end .I have not started any work to solve the problem and presently just gathering as much info before getting started which might not be untill next year as the Cdn prairie winter is in full swing & I am unable to ride the bike .Just wandering if any one has had this problem and what causes it & how to fix .Thx for any info.
Here is the post

So just as I was finishing up with the last thing on the list of problems with the Goldwing to get her road worthy a new problem arose.

She is leaking oil out the left exhaust.
Symptoms
-Oil dripping down onto the center stand where the sportster muffler attaches to the headers. Creating puddle, so its a decent amount.
- -Smoke billowing out of the exhaust.

There is no oil in the coolant overflow
The oil has NOT been overfilled. Its half way from full and low like Randakk suggests.
It has been on the center stand for over a week (not on the side stand)
It did not do this before. I have driven it several times a total of 35 miles while working out other issues on the bike before this started happening. So it is not just residue oil in the headers or exhaust and it is not from being on the side stand.
I read this could be a head gasket leaking. Anyone way to confirm or deny that?
Any other suggestions?
Thanks guys!

You are having a blown head gasket coming on. The steam/smoke will be sweet smelling. The steam is cleaning residues in the header and mixing with residue and dripping out.
Check the spark plugs, compare all 4. One or two cleaner than the others? While plugs are out, cold engine, put cloths draped over plug holes, kill switch off, crank over the motor, is there wet hitting the cloths?

Thx,for the info .It's been awhile due to the un heated cold garage ,but I did pull the plugs which were brand new and had probably 45 minutes of run time ,only on the lift not actual road time ,I found the two plugs on the left side where there is no smoking issues looked normal , the right side which has the problem with continuous smoking of what I would consider whitish smoke with sweet smell the plugs
looked hardly used and one was very clean .I know for a fact the engine was running on all four cylinders as I removed the plug leads while the engine was running one at a time on the right side and there was a definite drop in power .Just wandering if coolant is entering the combustion chamber would it still fire My thinking is if it was bad rings ,warn valve seals or warn valve guides then for sure the plugs would be oil fouled instead of being clean .I caught some of the oil dripping out of the header pipe exhaust connection ,did not find any evidence of coolant with the oil sample .I also did a compression check and got 120 psi on all four cylinders ,unable to do a leak down test .Was planning on waiting till spring to ride the bike & try adding oil additives to free what maybe could be seized rings but evidence pointing to leaking head gasket .

Yes you probably have a small amount of antifreeze leaking into a cylinder which causes steam when heated and sweet smelling and yes the small amount of antifreeze will not effect the running until it starts leaking a lot into the cylinders, which will burn off as steam.
The dripping is steam cleaned header, stuck on exhaust carbon in the header, mixed with steam which condenses as it cools and drips out a hole, not oil as you are thinking.

Well thx for the info as this has convinced me rather than wait and probably waste money on oil additives etc thinking it might be seized rings I will go ahead and order a top end re-build kit and re-build both heads ,I will update once the repairs are done ,

Why the thought that you have seized rings??? Top end gasket set yes.. .
Unless the motor was seized don't worry about it. The rings will loosen with use. Squirt a few drops of Marvel Mystery oil in the spark plug holes and crank over the motor with the kill sw off to move the MMO around into the rings.

what he said ... plenty of people (myself included) ended up with an awesome engine after getting ugly compression numbers at first.

The reason was thinking maybe seized rings was due to the amount of smoke from the exhaust & oil dripping out the header pipe , the bike had sat for about 4 years ,initially it would not start and there was alot of cranking of the engine by the previous owner to get it started which it never did due to the bad gas .The info gathered so far on this site like white sweet smelling continuous smoke ,clean plugs ,the dripping from the header pipe has definitely convinced me otherwise .

You have leaking headgasket. Not rimgs. Sweet smell is antifreeze.

My symptoms were similar on a 76 that sat here in the desert for four years at least. Once I got the heads off the right side gasket was quite rusted between the cylinders and around the fire rings. Glad I decided to remove the heads.

Qite common on the 4 cylinder wings that have sat a long time unused. The main problem is most people don't loosen and retorque the head bolts before running and retorque again like a new head gasket needs.

Well it's been over three weeks since the last post ,all the hardwork has been done ,heads removed & cleaned up ,valves lapped ,waiting on parts to arrive for the fun part ,the re-build. The side that was leaking the gasket was really badly corroded so that was the problem ,the cylinder walls are ok with no signs of scouring ,can just barely see the original honing marks .Just wandering if anyone has re-honed with the pistons in place and whether it's advisable to even attempt this .

Not enough depth to do that.

Parts arrived & had the re-build done in a few days , kept my fingers crossed & fired her up ,at first it was still blowing the whitish sweet smell smoke out the right side & my smile turned into a frown but after a minute the residue in the header pipe cleaned up and the smoke disappeared .I let it build up engine heat and ran without the rad cap on untill the fan came on ,I then shut it down untill the engine was cool to the touch ,removed the valve covers and re-torqued the head bolts one at a time by slightly cracking the head bolts and re-torque to 45 ft/lbs .I then re-started and let it run on the stand for about 1/2 hour ,revving the engine occasionally and letting the fan come on a few times,so far absolutely no smoke and all looking good but the real test will be out on the road but unfortunately that won't happen untill spring comes around .
The process is still fresh in my head ,so anyone needing to change the head gaskets on their Gold Wing 1000 & have doubts about something just ask .
