I replaced the clutch pushrod oil seal and now it pops out when the engine is started, dumping all the oil on the road.
It looks like the housing where the oil seal fits in has been damaged at the back so that the oil pressure forces it out.
It looks like the damage was there a while but the previous seal held without any problems.
Has anybody encountered this before?
I'm wondering if there is a safe way of using an adhesive to hold the seal in without the risk of it dumping the engine contents on my back tire.

In order of likely causes based on what you've said, first would be the wrong seal, after all, the last one held OK. Scratching up the housing with a chisel or centre punch is actually standard practice for a seal that doesn't fit tight enough so it's unlikely to be caused by the damage you can see. The crankcase is ventilated by other means offering a pathway of much less resistance, assuming that's not blocked there wouldn't be enough pressure to blow the seal out.
Think about it logically, the old seal didn't blow out and the new one does and nothing else has changed, what does that suggest?
I use Loctite 641 for seals and bearings but I really don't think that's your problem, I've never heard of this before (on an FJ).
Where did the seal come from?

That's funny....Crankcase venting is not the issue. The oil pressure on the clutch push rod is considerable as anyone can attest who has started their engine without the clutch slave installed.....
Just ask my cat.....
Did you use a genuine Yamaha seal?

...and it gets funnier.
So you're saying the seal is subject to oil pressure and this forces it out. How does the seal come to have oil pressure bearing on it?

Noel,
The information you seek regarding the pressurized oil at the seal can be easily found in the GYSM...
Mick, snap a photo of the housing with the seal and shaft removed. I can advise if there is damage.

Credit where credit's due.
Pat, I suspect it wasn't intentional but Randy responding was a knock out tactical move. You avoid answering and I can't make any further comment.
Maybe we'll get to revisit it sometime in the future.

Thanks Randy, I don't have a manual but I know what you're referring to and that wasn't the information I was after on this occasion.

Noel, I don't understand your confusion....
The oil pressure on the clutch push rod seal comes from the oil pump...not from pressure in the crankcase.
Do you agree with this? If so, why do you even mention crankcase pressure?
It's ok, no big deal....you just got confused....
.....again....

How much of the naked clutch can we show before it turns into FJporn?

I literally just googled to see if the terms "male" and "female" are used in the USA to describe fittings (because my post would be deleted if they didn't) and found some very funny but completely serious content explaining the obvious origins of the terminology, haha, one guy even apologises in advance for the crude reference. :lol:

Noel, I do not believe your recent post was deleted by any of the admin. When a post is reported it is to be addressed, it is discussed prior to removal.
I have inquired with all the admin and waiting for their response, but they know the procedure.
If it was removed, I will let you know. But of it wasn't, then something on your end occurred.
Now, hopefully Mick was able to get the assistance he originally requested before you steered the topic elsewhere.
Randy - RPM
Noel,
Just a quick follow-up. Your post was not edited or deleted.
As a reminder to all, if there ever is a post deleted or edited, the person who made the post is advised via PM of the reason of the administrative change(s).

Thanks for the update Randy but I'm long past worrying about how or why. Given the extent of fiddling with my posts over the last couple of years, this is insignificant.

My final word on the subject was to suggest that from his description and sequence of events, the seal was the most likely culprit and encouraged him to think the process through for himself. Advice Pat then repeated and I think perhaps even you did the same. Good teamwork. Sound advice endorsed by two of the forums technical experts and uncluttered by too many replies, textbook assistance, perfect.
If only it had been left at that.
It was Pats following smart arse comment that "steered the topic elsewhere," not me, but it was fortunately
after Mick had been given his advice, so there was no overlap or contamination of the information. I think you have confused me with Pat, (he's the one with the hair :biggrin: )
I don't mind copping a bit of flak from time to time but I'm not going to be someone else's whipping boy.
