So far so good with mine. I think running the crankcases under partial vacuum must help.

Magazine testers of co-op Triumphs consistently used to marvel at their oil-tightness so it can be done. Probably one or a series of ham-fisted home mechanics destroyed the Meriden craftsmanship before it was passed on to you ?

Good to know... Winter's coming in my part of the hemisphere. Something to strive for when I'm grounded.

Well,

I can only speak with any authority on the earlier models, but I do not accept that oil leaks are either inevitable or necessary !

All the Triumphs that have gone through my hands leaked - when I GOT them. NONE of them leaked when I passed 'em on. All down to surface preparation, quality parts and care when assembling.

I currently run two pre-unit Triumphs. One Dynamo model, Daisy, which doesn't leak, not even from the dynamo (except recently in Sweden when the cork seal actually broke in half!)and one alternator model.

I *do* get a couple of drips occasionally from the engine breather? But that's about it.

I've often heard it said that ALL Triumphs leak, especially from the pushrod tubes?

Load of old Bollix, in my view. An excuse for bad assembly is what that is.

Graham, you might appreciate this with the mentioning of the PRTs.

I've disassembled what was my late dad's T140. I remember building the engine 15 years ago and I could have sworn we put them in.

However, when the head came off, there wasn't an o-ring answering roll call on the top of the PRT. Either fore or aft!

Now, that must have leaked, you say? Actually, it wasn't bad. I'd wipe them off every month or so and they'd be as good as new. Where those o rings went? Beats me. But I know it didn't leak!

FWIW

Damn bloody bastard thing of mine just did a brisk 120 miles in the company of Ducatis and other bloody heathen things and wept not a drop !

I suspect that it is trying to make a dickhead of me.

Tiger---your use of that word brought back a memory to me.
I am Tridentman on this board but my real name is Richard Beard.
The abbreviation for Richard is of course Dick.
I attended a technical conference once where they got my second name a bit snarled---they had me down as Mr. Head.
Of course the receptionist said---Good Morning, Dick Head---I thought it was a bit too close to the truth!

Here in Oz we had a country western balladeer (Stan Costa) who wrote and sang a song called Richard Head. What a good song it was too. RR

I think the iron headed ones give less pushrod tube oily grief.

Well I have ye olde 1970 Tiger and it leaks from many spots, but each of these leaks is ye small one. Quite wee little leaks they be. I'm in ye process of attempting to address each leak one at a time with patience and me considerable technical prowess. The leaks are perhaps even what one might call weepage. For example if I run it on the highway at 65 mph for an hour, the top of the oil tank is covered with a thin film, I guess seepage form ye oil tank cap. Much to me dismay the acorn bolts on the primary had tears of oil running of them, then I found out through looking through me olde parts manual that there should be copper washers there, but they are absent, lo. The primary and sump drain plugs both weep, there are ye drops on the floor of Rippington's garage, lo. I just bought a new primary drain plug which I'll install later and I'll try annealing the sump washer and sanding down any imperfections in the mating surface. Ol Rippington, he hopes to get it reasonably oil leak free, but agree that if you have a fun time riding it, why stress out if a bit of oil leaks, still I must attempt to fix ye leaks. 'Ol Rippingtons Tiger has leaked and or burnt about 1/2 pint of oil in 150 miles of barn burner riding, 6000 rpms she did see on the last journey so perhaps me 'ol Triumph when ridden like the dickens will use and leak a wee bit of oil, can't be helped can it??

Here's a good example - from last summer...

Grandad has a Tiger 90, and it has always leaked from the usual places. Last summer he did a top end rebuild, and afterwards it leaked from all the usual places.

I told him off BIG time. "You had this apart, and you DIDN'T fix the leaks?" I couldn't believe it. Grandad complained that he'd done all he could, and then He fell back on the old favourite "well they all do that, anyway"

So, I made him take that top end down again, and we did all the facings (they were crap) and we carefully 'trued' the push rod tunnel lips, and we cleaned out the rocker box 'o' ring grooves, and we made new gaskets, and we put it all back together ....

Didn't leak a drop.

Still doesn't, a year on.

Like I said, preparation, and care in assembly is all it really takes.

Poor old Grandad!!

I'm a G'pa too and all the young fellas pick on me as well.

Grandad is going to feel very insecure now. For years he's relied on those little oil leaks as indicators he has oil on board. What has got to rely on now? RR

mine's been oil tight for years. lately I've been getting some drips when sitting on the side stand. I suspect it's gear oil leaking down the gear box mainshaft splines because the side stand lug is bent and it leans way over.
