leaking engine front gasket 1100

Postby Flyboy6 » Mon May 11, 2015 9:59 am



Dang - just spent 20 hours up inside the engine front, replacing water pump, checking coolant system, etc, all good now, except put her all back together and put fluids back in and now have a serious oil drip in lower right side, below the oil filter cover. It is at the front cover/case gasket, not the oil filter cover. I followed advice on the forum here and did not use any gasket sealant, put the new gasket on dry. Now I'm second guessing this. Interestingly, the new water pump cover gasket had a thin bead of sealant applied at the factory - the bigger one did not. Both OEM parts.

- Do I have the option of a period of time to pull the front cover (aaargh!) and re-use gasket, or is it now toast?

- Advice on sealant to use with gasket - I obviously have some scoring now on the face of one of the components (had a very difficult time getting old gasket material cleared off)

I will pay face value for all free advice.

The gasket faces really do need to be flat and smooth for the gasket to mate and seal properly. It is also essential that the gasket be there, as without it, you will not be able to shift gears due to clearance issues (very tight tolerances). I think your only option at this point is to remove the cover, clean the gasket off, and redo it with a new one. If the faces are scored like you said, you may have to use some kind of sealant in order to get it to seal properly without leaking. Just make sure whatever you use does not squeeze and migrate into the inside of the engine when you seal it shut.

Thanks - figured this is my likely route - draining the fluids now and psyching myself up for another episode of tugging the rad out.

If gasket just put in comes out clean, is it safe to put it back in?

What would you recommend as a bead of sealant?

Back in the early 70's I used Permatex which is still available. I tried some Three-Bond in 2000 and have been using it since. Put on a thin coat and apply the gasket, smoothing it with your fingertip. Apply a thin coat onto the gasket surface and give it time to cure out. Install the part as normal. Three-bond is available from Honda and Yamaha as "Hondabond" and "Yamabond". I use it on my British bikes which are notorious for leaking, and they do not leak one bit.(Beezerbond I guess.)
I used it to replace the water pump on my Goldwing. No leaks. Worth a try.

I always use black rtv. Just a thin coating with your finger, works great. It comes off easy like rubber if you ever have to redo it also.

Thanks for the note. Just finished putting the gasket back in with some gentle coating of black RTV (Permatex) to help with any irregularities - though I re-examined the faces and they were pretty clean and flat. Cinched up the bolts and hope for the best. Did it this time with rad still in - what a fit getting my big mitts and little wrench in there to do those top three bolts. (was glad for the reminder to tuck the right side top bolt in before placing the cover - otherwise frame blocks the path.

So, later today I'll top up the oil and see if it holds. I REALLY don't want to dive back into the engine a third time - my knuckles can't take the bashing and the neighbour kids are learning some new words. Steep learning curve at the moment.

btw - Wing Admin - thanks for note some time ago about the 'Mechanix' gloves - making life easier than going through many pairs of the disposable ones each day.

Just be careful to keep oil/hydraulic fluid off the Mechanix gloves. Once you get them oily, you'll never get them clean! They soak it in.

I went back and looked at the posts and did some investigating on the nitrile gloves, especially the ones at HF recommended.
Most of the recent reviews say that "they aren't what they used to be", seeming thinner and tearing easier.
Reviews from the big box stores say basically the same.

Is this the case? Have you found another alternative, or just dealing with it?

When wrenching, I usually just use some cheap leather palm (~$3 each) with a latex glove inside if I know that it's going to get messy.
It's never too late to have a happy childhood!

HF has various thickness of Nitrile gloves, I always buy the thickest ones, as they last the longest before tearing.

I read the post saying you bought the 9 mil ones.
Have you noticed any difference in quality since your post about 1 1/2 years ago?

No, because the last time they had a crazy sale on them, I bought so many boxes that I haven't needed to buy any more in a really long time! :)

just bought a box of heavy duty black gloves at NAPA (same time as I bought the others) and they are ok- pretty tough - but sized kind of small, so a pain to get on, and once off, hands are damp, reach for a new pair - dry the other ones out.

Finished this last job with bare hands and went at them with the orange pumice and 60 grit sandpaper.

Speaking of which - just filled up the fluids and ran the bike for 10 minutes. Aside from smoke where I dribbled oil down the headers on one side (took valve covers off and did gaps while I had things apart) - now the gasket seems tight, but I'm getting some coolant dribble out of the dribble hole, which is annoying. New o rings in there, and no play in the bearings on the new pump, so I don't know what's up, but I'm going to live with it for a while. Time to stop wrenching and ride for a while.
